"Boot configuration data is missing or contains errors"

Q: "Boot configuration data is missing or contains errors"

This is the message I get when I try to boot:

"The boot configuration data for your PC is missing or contains errors"

File: \EFI\Microsoft\Boot\BCD
Error code: 0xc000000f

I had a linux partition installed separate from my windows partition. I deleted the linux partition, which apparently messed up the windows boot loader since it seems to have been overwritten by the linux boot loader. i tried installing linux again to restore its bootloader, but selecting windows from the boot loader is no use since the windows boot loader no longer works. i've been using the command prompt in the windows 8 recovery environment but have not had success so far.

A: "Boot configuration data is missing or contains errors"

Delete Linux, boot off of the Windows 8 DVD choose your language and Repair Your Computer. That should fix the boot file.

I tried copying a fresh version of the file to \Windows\System32. No dice. I tried renaming it all uppercase and then all lowercase. Nothing. I put a copy in the root directory. No effect. I tried everything I could think of, but nothing worked.

Then--doh!--I stopped thrashing and did what I should have done initially: I dug into the Microsoft Knowledge Base and learned about XP's built-in Rebuild command. It can often easily fix "Missing HAL" and similar problems in just a minute or two. If you know about this command and how to use it, you can potentially save yourself hours and hours of manually reinstalling or rebuilding a failed operating system.

We are getting the above error randomly on some of the laptops we have deployed. The error comes right after you boot or when the windows 7 is left running. There are no special software running. The error in details is below.
"The boot configuration Data (BCD) settings for the following boot application have changed since Bitlocker was enabled
boot appplication: \windows\system32\winload.exe
change settings: 0x26000090
You must supply a bitlocker recovery key to start this system.
Confirm that the changes to the BCD settings are trusted.

If the changes are trusted then suspend and resume bitlocker. This will reset bitlocker to use the new BCD settings.
Otherwise restore the original BCD settings"
Can anyone please explain on how to correct this error. As before this is happening on few of the machines and we are seeing more as we go. Any tips would be nice...Thanks

somehow my win7 system boot records seems corrupted hence it's showing OS not found. i have tried with bcdedit /enum & its showing "The boot configuration data store could not be found. The requested system device cannot be found". tried
bootrec /fixmbr & bootrec /fixboot which is showing sucessfully. bootrec /rebuildbcd is able to detect C:\windows but showing "the requested system device cannot be found" while adding installation to boot list. i went into diskpart, selected
EFI partition & able to see EFI contents (bootx64.efi/bootmgr.efi etc) there.
Kindly suggest how can i recreate BCDstore without reinstallation.

A:BCDEdit /enum showing "The boot configuration data store could not be opened"

When you boot the machine make sure you are booting with a UEFI device i.e. if you boot with a Win7 CD, make sure that the CD is booting from UEFI and not legacy BIOS CD. You have to boot from the same type of partition that the hard drive was created with
for BCDEdit to work.

So if you booted from WDS network, then you need to boot from a UEFI ethernet/pxe connection.

Hello. Last night I set Acronis Disk Director to merge two partitions on my C drive.
I had an unnallocated 100mb that used to be partitioned as system reserved, but I deleted that partition as it was not needed. So I made a new partition out of that unallocated space and set it to merge with my primary partition on my c drive. It restarted my computer and 40% through, showed an error and restarted quickly. Now I get the following message when attempting to boot my computer:

File: \Boot\BCD
Status: 0xc0000225
Info: The Boot Configuration Data for your PC is missing or contains errors.

The second partition, that I attempted to merge, now has 1mb of space on it. Whenever I try to run chkdsk on the primary partition, it says that the disk structure is corrupt and uunreadable.

Any help would be greatly appreciated. I need my c drive recovered.

So I have been literally trying to fix my windows not being able to boot at all for more than 12 hours straight till now. I almost read every single article and troubleshooting step on the web to find a solution but nothing seems to work. I will keep it short as much as I can.

I was playing the Division game on my PC then suddenly the PC crashed and then it restarted by itself but stuck at the windows logo forever. I tried system restore using the windows recovery CD then it failed as well, since then, whenever I try to boot from my HDD, it gives the error 0xc00000f "The Boot configuration data for your pc is missing or contains errors"

I then boot through the CD in the cd drive, have only 4 or 5 options which are

1 - Reset this PC
2 - Refresh this PC
3 - System Restore
4- Command Prompt
5- Automatic Repair

the "Reset this PC" gave an error "The required drive partition is missing"
the "Refresh this PC" gave an error "The drive where windows is installed is locked. Please unlock and try again"
the system restore gave an error something I don't actually remember but its like "Choose your OS and then try again"

I tried the so-called commands in the CMD (bootrec /fixboot, /fixmbr, /rebuildbcd, etc...) and all didn't work. Also the rebuildbcd command showed that "Total identified windows installations is ZERO"

Tried the diskpart command as well and when I listed all the volumes, all appeared as Healthy a... Read more

Hi I'm trying to fix my nephew's laptop.  It is a Toshiba P75-A7100 running an Intel Core I7 processor. It came with Windows 8.1 installed and he upgraded to Windows 10 when it was available.  other than these recent developments the laptop has been running fine.
Right now I'm getting a Windows failed to start message.
File: \EFI\Microsoft\Boot\BCD
Status: 0xc000000f
Info: The Boot Configuration Data for your PC is missing or contains errors.
He was receiving Unexpected Store Exception errors, the first time while updating a steam game, then while working on a photoshop project.  He ran system file checker (sfc.exe) and the output file has 23,977 lines most of which say Primative installers committed for repair.  (i have a copy of this file if needed)
I removed his hard drive and attached to my laptop with a USB to IDE/SATA cable adapter and ran a AVG ( my anti virus) scan on it and it came back clean.

Hi Folks,
I am running with an ASUS Pro31 Series and Windows XP Pro. In trying to fix a problem with Microsoft Outlooks, I was frequently rebooting my computer (trying to access the SAFE MODE boot menu) and it has now permanently failed to boot and has the following error on screen:

"Missing Operating System"

I have tried but cannot seem to access the menu where you can select to reboot in "Safe Mode" etc. I can only access the BIOS SETUP UTILITY using F2 and the BIOS RAM EASY FLASH UTILITY using F4.

Using the recovery DVD I got as far as the three options:
- Recover Windows XP to first partition
- Recover Windows XP to entire HD
- Recover Windows XP to entire HD with 2 partitions

I stopped there because it is essential that I retrieve the data from the HD. I am not concerned about the laptop, just the data. Yes I am a dumb dumb for not backing all of it up.

This laptop was supplied to me by my employer, so I am not sure how many partiotions it came with etc. Is it safe to assume that the first partition contains the C: drive data?

Are there any fancy tools I can get my hands on - over the net or otherwise - to try to get it booting normally again?

If not, what options would I have for trying to get the data off the HD?

Also, why does is it that I cannot access the SAFE MODE start up menu?

I have no idea where to start, a friend of mine sent me a link for Windows 8 Pro link, it's not original nor cracked, it's just non-activated (it kept asking me for activation key), that's not the problem tho.
I have windows 7 already, downloaded the iso he sent me, I tried to extract it into a flash, tried to boot from it, it didn't work, I said why not extracting it? I did, and opened setup.exe, and installed windows 8 successfully! And I could dual-boot normally.
I went back on windows 7, backed up my files into another partition, renamed the partitions into Windows 7, Windows 8, Others(backup) and went to windows 8 and started restorting from the new parition, after all I went to delete windows 7 in a stupid way by deleting the Windows 7 partition, it didn't work fully, some folders stayed as Windows/Windows.old ....etc, so I went to windows 8 partition to extend it since I deleted lot of gbs off the windows 7 partition, I've done so, and there was option saying to make it primary parition althought it was checked on windows 7, I checked on it and it went unchecked on windows 7, I didn't care much.. and it asked for reboot, and I did.

I've been reading this post as it's the only thing I could find on the net about my problem.

I just upgraded from Vista Home Premium to Win7 professional x64 hoping to fix the above mentioned problem. After a complete re-install Im getting the same errors.

Im not sure of the proper terminology here, but during startup the computer does a scan of all hardware and "Volume 0" has a "failed" message.

The odd thing is that sometimes after a few restarts and pointless boot menu visits the computer starts up fine.

I tried windows repair feature by booting from the disk, but when I get to the window where i select the operating system to repair, its empty. Drive C, where the operating system is, is not showing.

I have a feeling that the hard drive itself has gone bad and is very unstable. Please let me know if I'm missing something or we just need to get a new HD.

Thank you

A:Win7 pro startup error "Boot MGR missing"/"Operating System Not Found

What type of hdd do you have. For example if you have a Seagate drive, there is software you can run to do a diagonostic on the hdd before the operating system boots.
This would be a good idea, especially if you were having same issues when Vista Home Premium was installed first.

Do you have more than one hdd installed. If yes, make sure in BIOS settings, the proper drive is selected for First Boot. And better yet make sure its the only drive attached when booting.

Here is my situation. I have 2 hard drives. C:, which is where I have Windows XP installed and D:, where I have various music, movies and games installed. Basically D: is my storage drive.

I decided to set up a dual boot configuration with Windows XP and Vista Ultimate. As I said Windows XP was already installed on C:. I used partition magic to reduce C:'s size so I would have enough space to create a new partition on the XP drive for Vista. I created it and installed Vista fine and now I can choose whether I load XP or Vista on startup.

Vista seems to be running fine however when I open explorer I encounter a problem. C:, which in Vista is the main partition displays and can be accessed fine. D:, which is the main partition for XP (and is displayed as C: when booting in XP) displays and can be accessed fine. E:, which is the storage drive I mentioned (displayed as D: when booting in XP) earlier is named Access Denied in Vista. When I click on it in explorer it says Access Denied. When in XP all drives and partitions display and can be accessed fine. When in Vista, all drives and partitions except E: (D: when in XP) display and can be accessed fine.

I have read in some forums that I should "take ownership" of E: (in Vista) and that will allow me access. As I understand it this would then deny me access to it while in XP and that is obviously not good because the reason I chose to dual boot is so I can access everything from both operating systems.

What I'm trying to do:
Ultimately, I want to have a clean install (wipe everything) of Windows 10 on my computer.

What my computer state was before the trouble:
Windows 7 Home Premium and Linux dual boot. Everything worked great and dandy (except intermittent issues with DVD drive not reading disks). All my files were saved to external hard drive. Ready to be wiped and have just one instance of Windows 10 installed (No dual boot)

What I did to break it:
I deleted my Linux partition using the instructions found here.
I also had 3 other partitions, my primary one which has Windows 7 on it, and two others that care pre-installed on the machine when I purchased it brand new. I can't recall their labels but I think one had "data" in the name with some numbers, and the other was "restore". I might be totally wrong about that though.

I decided, "What the heck, I've never needed these before" and so I deleted both of those as well. I'm guessing this was a poor decision but what do I know. The computer ran fine while it was still on but when I rebooted (to see if my linux partition was gone) that's where it all went wrong.

What's wrong and how I've tried to fix it:
When I start it up, I get a black screen with the grub rescue terminal and this text: "error: no such partition grub rescue>". Don't know much about grub (anything at all actually) but after some googling I tried to create a Windows Repair Disk and run it. Burned the disk follo... Read more

A:"A required CD/DVD drive device driver is missing" and other errors

Solved it! And then went and cried in a corner because it was so simple.

Something I had failed to realize in the past was that of the 4 USB ports on my laptop, two of them are USB 3.0 ports. During my efforts, I had tried the thumb drives on (by sheer chance) both of the 3.0 ports rather than the 2.0 ones. My laptop (and most other modern computers I believe) require extra drivers to be downloaded before being able to use the 3.0 ports that aren't on the computer's firmware. That was the drivers it was complaining about not having.

So, for other troubled souls having the same issue in the future; verify that the port you are trying to load the USB on is a 2.0 port rather than a 3.0 port. The difference is pretty easy to spot when you're looking for it. USB 3.0 ports have an "SS" (for Super Speed) next to the US symbol, whereas USB 2.0 ports do not. See below image for a visual.

Hey guys!

I just messed up my only computer atm

Firstly I created a partition of 1 GB on my 128GB OCZ Agility 3

Then I used bitlocker to encrypt it, and then for some reason when I tried to reboot the computer after doing the aforementioned, I get the message that windows cant boot, because the boot configuration is missing or conatins errors

I dont see how BitLocker and Disk Management can screw something up so much so that they either deleted or encrypted my boot config rendering me unable to boot up the computer.

What I did was shrinking the c:drive by 1000mb then formatted and partitioned those 1000 mb into a new drive. Secondly I encrypted the 1gig with Bitlocker with a short 12-character password.

I am now unable to boot up my laptop. Anyone has ANY idea what to do, I am so tired of screwing up my computers from me experimenting with various things......
I will accept all answers with open arms!

I have one particular series that is showing up as an "area" but I want it to be drawn as a "line" instead, so it DOESN'T fill in the area below it. I currently have the "background" as "none", but now I have a line from the last value down to "0", and that's what I want to avoid...

Thanks in advance!

Hi, I'm back with another issue

So, my laptop Windows Vista 32x.

My Hard-Drive I guess had an issue. And my data vanished.......... But the HDD is reading as if it is still there. I re-installed windows, Went to windows.old And my Data is not there............... But I have 1GB left on my HDD is there a way to get the data before I format it?

Update 1.

I downloaded the everything program. Entered the names and found the files. When I went the folder, it was empty, I did folder options to show hidden views, I got the data, But the Files are kinda Shaded out in a light color if that makes sense

Hello Pinakfans,

A faded file or folder indicates that it was either set to be hidden, or is a hidden system file. You may be able to unhide them by unticking the "Hidden" box as in the tutorial below to not have them faded anymore.

Hello !

It's been a while now that my Windows 7 computer gets a crippling "server is busy" error.
My problem, in a nutshell : I don't manage to identify WHICH process is responsible for this, I also don't know if recognizable patterns are logged as events, or not

Description of the problem:
By crippling, I mean:
- I cannot run any program requiring to be elevated to admin level. For instance, I can start the tasks manager, but if I click the button to display the processes of all the users, the tasks manager will suddenly freeze. Or I can't also open any of the Windows administrative tools.
- Some other programs cannot run either (meaning : I click their icon or win-R their name, they exist as processes shown in the process manager, but their windows are nowhere to be seen, even with alt-tab), like Photoshop or mspaint (hence : no screenshots of the problem) and, frequently, I may click the Start button and have its entries shown, but clicking inside will be ignored
- fundamental programs don't start at all, like the antivirus (Comodo), firewall (Avast), Samsung Magician.
- I just noticed, it's an edit : opening folders, opening a library, opening the files browser, it all fails with a big white cross over a red circle, telling the remote procedure call has failed O_o

This happens most of the time on the first boot of the day, but there are days (like here, sigh) where even two reboots later, the problem is still present. It's raising in frequency, healthy boot... Read more

Ok, so I had the "file recovery virus." I was using malwarebytes and Another malware removal program (can't remember that name) to get rid of it. I remember one of them listed a file name with "boot" in it as infected so I deleted it as suggested. Well now I can't boot windows 7 64 bit on my HP Pavillion laptop. It said no bootable device was found.

My husband made me a repair disk from his work computer but Under the system recovery options, it is blank. It says "if your operating system isn't listed, click load drivers". When I click load drivers, there are a ton of files listed and I don't know which one to choose.

If i dont boot from CD, I am also getting a windows boot manager screen that says to insert the windows installation cd (which I don't have) and restart.

Have you tried the factory recovery option built into the PC frm the factory, I believe it's the F12 key (for HP) at PC startup, that will over-write any date you may be trying to save though.

And I've set the SSD to the primary boot, I've tried to directly boot it via BIOS but they both still give the same result, I've put the Win7 disk in and done a repair but still, no change.

Since my OS is installed to my SSD, is there a chance it could have corrupted the files or the actual drive when the computer crashed? From what I heard SSD's seem to be a bit fragile.

Any help or recommendations would greatly appreciated.

Startup repair (up to 3x consecutive runs might be needed, but probably only 1) will fix it.

You might try your luck with "finding" a Win 8 (or 8.1 if you have that instead) .iso to burn or make a USB out of, so you get to startup repair. Check hashes if you do this, compared to known well discs or official disc.

Someone will probably have a suggestion or two how to get one. Maybe even officially.

It would be helpful to everyone if you give the exact machine model and submodel (if there is one).

Hello all, I'm new & having a spot of trouble so I decided to ask for some help here after seeing many other similar issues resolved

The current situation:
I have 1 partition containing my windows 7 install, but it won't even get to the stage where I can select (e.g.) safe mode because it hangs at "Verifying DMI pool data....." after the POST. The windows 7 partition is the active partition. Startup recovery via the windows 7 cd does not help, and bootrec commands give "element not found". I think it's because I deleted some crucial files off what was the boot partition (an XP partition), then deleted that partition.

The question:
How do I get my windows 7 install to boot?
The Full Story (aka the wall of text)

How it happened

When I set up the installs on my current system hard drive a year or two ago, I initially installed Windows XP Pro (x86) on a 100gb partition, then decided to install Windows 7 Ultimate x64 on the remaining 830gb or so. About a month later I realized I barely used the XP install but didn't want to reinstall everything, so from my 7 install I deleted all the directories except Windows and any directories marked as System, which were hidden (i.e. left all files in the root of the XP partition alone). I intended to resize the XP partition later & use the reclaimed space, but I ended up unmapping the drive letter from the XP drive & so forgot about it.

Fast forward to a few days ago. I was (ironically, when you cons... Read more

A:Boot failure - Hangs at "Verifying DMI pool data"

Solved it; my system hard drive was not the first hard drive in the BIOS boot priority list. Once I changed the priority to make that hard drive the first hard drive, it got past the Verifying DMI pool data" step after about 15 seconds of waiting, and gave me the "BOOTMGR is missing", "Press CTRL+ALT+DEL to restart" messages.

I went into the setup dvd, and this time it actually spent some time searching for windows installations. It found one and prompted me to fix it (separate from startup repair), I chose no and went into the command prompt and did bootrec /fixboot. I didn't get "element not found" this time!

Sadly after a restart I still couldn't boot into windows, so I fired up the setup CD and this time allowed the repair. After a reboot, it still didn't work, so I fired up the dvd again yet again and used the manual "Startup Repair" option from the list of about 5 options. This time the diagnostic information gave a different message, something like "the boot record is corrupt", and after clicking Finish, it restarted and windows booted

Hi, i decided to upgrade my windows vista to windows 7 so I did a clean install.

This is my first time trying to fix a computer, so please forgive my ignorance.

I recently changed the motherboard and hard drive on my hp computer. Before I did that, I was able to create a windows 7 recovery cd (before the old HD died entirely), and I also have a system image on an external hard drive. Problem is that I cannot get past "Verifying DMI pool data... INSERT SYSTEM DISK AND PRESS ENTER". At first, I would put the disk in, but my keyboard wouldn't work, so I couldn't press the enter key. (Although oddly, the keyboard does work to get me into BIOS and in BIOS). So, after some research, I went into BIOS and changed the USB keyboard setting to enabled. After that when I went back to try to boot again, as soon as it got to "verifying...", it waited a couple of seconds and then just turned off. I didn't even have time to put a cd in and press enter, even if I wanted to. Now it just keeps doing the same thing. I have the boot priority set to CDROM first, then HD, and to be quite honest, I am not even sure that was the right move. The HD is blank - I haven't done anything to it. The only thing I know is a friend who is head of IT for his company, gave me this HD because he had it lying around. It is in working order, but I have no idea about partitioning, or what the even is. I don't know... I am confused and have spent HOURS trying to figure this out with no luck.

Hoping someone can help!

I could be wrong here (it will definitely need clarification) but an HP machine will have an OEM install, and since you've changed the motherboard that Windows installation will no longer be valid. Maybe that's why the recovery disks aren't working.

I just got a new Hewlett Packard computer with Windows XP. The CD drive is a combo CD reader, writer and DVD. The main reason I need it is to backup my many documents, database programs (RootsMagic family history, Quicken, etc.), photographs and drawings. The pre-installed burning program on the computer is Adaptec's (I think) Sonic RecordNow!, which is useless for my needs because of the way it works. The HP tech suggested I download DLA to enable me to use "drag & drop" through Windows Explorer, but I haven't had much luck with that, either. What I need is to be able to use a CD-RW as a giant floppy - to add, delete, copy, edit and move files, just as I do on my regular floppies, using "drag & drop" through Windows Explorer, or "save as...".

Assuming either Vista or Windows 7, then THIS THREAD has the typical answer.  Of course you need a real install disk for Vista or Windows 7 or a repair disk.  You can borrow an install disk from someone and boot to the disk and pick repair instead of install.  As long as you do not try the install it will be fine.  Read the link. HP does not provide a disk, so that is your choice to find one.  Like I said, you can borrow one.

 Hi folks, couple weeks ago I bought a new server to my company, and installed Server 2012 Foundation to it. Also, using Intelligent Provisioning, I enabled RAID 10 (4x1TB HDD).

I'm trying to do a fresh install of Windows 7 Ultimate 64bit but i can't get the installer to load.
I have access to a Xubuntu install and a OS X install.
The original hard drive Windows 7 was installed on stopped working completely. So, I've bought a brand new one.
I followed the steps I did the first time I installed Windows 7 - converting the iso to and img with OS X's hdiutil and the dd command to burn it to a USB.
This time I would just get a "please insert proper boot media" error.
I went to my Xubuntu computer (it's used like a chromebook - i'm not a big linux guy) and tried WinUSB.
These USB keys lead to a screen that had a flashing underscore a few spaces from the top of the screen.
It dawned on me that the first thing I did when I installed windows the first time was update the bios. So I tried flashing a few different BIOS versions, but none of them made a difference>
I really need help - I can't think of anything else to try
Thank you very much!

Hi all,

I'm puzzling this one. In the folder options when I choose 'view' the radio button to show the hidden files is missing. I've already checked the registry at the HKLM/Software/Microsoft/Windows/CurrentVersion/Explorer/Advanced/Hidden

and everything seems ok (value for 'Type' is 'group' etc.). Using the XP tweak (Kelly's corner #155) shows the hidden files, but the button still missing.

Another thing that I encountered with was that from the start menu the "Help and Support" not working. Again, the registry seems fine, and the process is activated (started). This came up when I tried to use system restore option - with no success.

Virus scan didn't find alerts of any kind

A:missing "show hidden files" button + "Help and Support" not working from start menu

Ok I found the answer (after quite a lot searching), as follows:

1. for the 'Hidden files' radio button - I used methods 1 and 2 from here-

2. for the helpcenter I just reinstalled it as described here -
note that the file 'dataspec.xml' is needed to be available for this, and it can't be done directly from the XP CD. The thing that worked for me was to insert the XP CD, and use the file that in my computer (C:\) and afterwards another file on the CD.

Again, all this happened with no virus detection, so I believe that there is no infection. However, if someone has remarks on the HiJackThis log I've put, feel free to add them.

Dual Boot WP/Win7.
My pictures are located on P:\ on separate HD, I can view the partition in Disk Management, but it will not let me set drive letter.

IF i attempt to make "active", i get a warning about "...if contains operating system...." etc..

Here is screenshot of when i attempt to add drive letter:, and a screenshot of warning when i attempt to make "active"

A:Dual Boot: Cannot "see" data partition

Yes, its true. It is not to activate a partition that doednt contain os. In this case your computer will stop working (bcoz that partition doesnt have any boot image).

Look for the "system reserved" partition (about 100 mb). If it is activated, there is no problem at all. The partitions containing os should have boot flag. In this situation, I think you will be able to operate all the partitions in explorer in either os, if there is not a ownership problem.

I think it is wise to have a third party disk manager (like acronis or paragon) to have a good dual boot system, and a bcd editor like vista boot pro or easybcd.

I made a recovery drive and set the UEFI to a USB boot, and when I tried to boot it with a blank USB it didnt recognize it, but when I used the recovery usb it recognized it. I did that to check and see if it actually recognized the recovery data.
Now when I boot it just has the Lenovo screen and the swirling dots. it's been doing this for about a half hour. Is this normal or is there an issued with the hatdware?

A:Boot Configuration Data is missing, Error Code 0xc0000185

The Error code: 0xc0000185 is an I/O error.
This can be a hardware problem or a software problem.
So the first thing to do is to run diagnostics on the hard drive ( )

If you have difficulties booting to the disk/drive, post back and we'll see about changing some settings in the UEFI to allow the boot.
I'm working on a drive that will do this for you, but it's still in the testing phase (and it's a 700+ mB download).
If the drive is dead/dying, you may have problems trying to recover your data.
Do you have a recent backup?  If not, post back for suggestions on how to best backup your information.
FYI - if it is dying, then it's best not to use the drive at all until you've done the backup.
If the drive does die fully, then data recovery gets very expensive (up to $2000 (US)) if it's even possible.

I have an old HP Pavilion 8260 that I got for free which is having some odd issues. Any time I try to boot, I get one of these 2 errors (first it was always Operating System Not Found, now it's Missing Operating System).

Here are the steps I've tried so far: I tried to boot from a floppy with a disk I know works; tried to boot off of the CD Rom; Tried disconencting everything except Floppy, CPU, and RAM; Tried resetting the BIOS by selecting "Set to Default" and by pulling out the CMOS battery (it was after doing this that it switched to the Missing OS error message).

The hard drive is dectected in the BIOS, as is the CD Rom and floppy drive. It properly recognizes the amount of RAM.

So, I was playing a game called Battlefield 2, and it was a little laggy, it was pissing me off so I restarted my computer. I don't know if this screwed something up, but instead of re-booting up, my computer told me that a file in the system 32 folder or around there (It's called system, I think) was corrupted or missing.
Whoop dee doo. I've had like this happen way too much, and I'm incredibly tired of re-formating. I do NOT want to re-format and re-install it, PLEASE, GOD, NO!

So, it told me to put in my windows CD and push "R" to repair it. So, I did, but that gives me a nice command line, and I don't exactly know what to do.

I tried restarted, and now without any error it just brings me to the blue windows XP screen before the computer goes to your desktop, but it just stays there without actually..going to my desktop and letting everything function. So, what do I do now? Is there any way to replace this file, or am I gonna have to re-format?

My hard drive crashed on my laptop. I had a running dual boot environment of Win2K and XP. Both the Win2K and XP were backed up with Acronis Ver11. After replacing the hard drive I created the partitions needed for Win2K and XP using a Win2K CD. Formatted and installed Win2k on the first partition. Did a restore of Win2K via Acronics. I used the restore because of the other software I had installed/running on the first partition (Win2K). The XP/OS application I have needs three partitions. The three were created by the Win
2K CD and then formatted via Disk Management (Win2K). Next I restored my XP/OS via Acronics on the second partition. Modified the Boot.ini file for both Win2K and XP. The Win2K boots no problem. Selecting XP I get the following error: Missing or corrupt file Windows\system32\config\systemd. I did copy in the NTldr and NTDetect from the i386 folder (XP CD), to the XP OS no change.

I am a newbie here, so apologies for the long post.

My PC recently went into hibernation mode, and soon after i restarted windows noticed sector errors and fixed them. HOWEVER, since then it will not start windows, and now it tells me "missing operating system"

I can access the motherboard boot screen and see all of the drives(including disc drive), i have used the command prompt and can see that all the drives are active, however the SSD boot drive is not NTFS but RAW.

I have tried using my windows 7(ultimate) backup disc & a windows 7(Home premium) install disc, but both will not let me access windows, without a fresh install.

Could this be as simple as the driver for the SSD is no longer on the PC?, and i now need to source it and install it?, or is it likely that the drive is ruined?

I have a NAS which has the windows backup's stored on there, however the PC will not let me access the NAS without installing Windows, can i install the Home premium version on a new SSD and restore the ultimate from my NAS backup once the windows install is complete?

In addition is there any way to rescue the data on the corrupt SDD?, or to reuse the SSD etc etc.

Sorry for all the questions, but hopefully someone can help!

Hello. I seem to be having a problem with the isapnp.sys file when I boot my laptop. Apparently the file is corrupt so I can't boot. I've looked through the Microsoft website and was told to use the windows repair console that comes with the CD to repair the file. When I attempt to use the command that replaces the isapnp.sys file, I get "Access is Denied" in the console. I think it may be because the console didn't ask me for an admin password so my system isn't validating me as admin. So I moved on and came up with the idea to burn the isapnp file to a CD by taking it from this computer that I'm on right now, but I can't boot my laptop into command prompt without going through windows first. I tried to use safe mode with command prompt but I still get the isa driver error. LKGC does nothing either because I still get the same error. Please help! I'd like to know what to do about the Access is Denied in the recovery console, or how to boot directly into command prompt without touching windows...The laptop has no floppy drive either...

I tried the good-old Control-Alt-Delete, yet nothing happened. Everything became unresponsive except for the cursor for a good ten minutes before I'd had enough and pressed the damn restart button on my computer.

My Gateway Windows Vista desktop won't start for 4 days. I didn't download any new software/hardware, and I've had the same OS installed without issues since I bought my desktop in 2008. It started with a BOOTMGR is missing error after a BSoD, and my computer could not detect my OS in WinRE. System Restore cannot find any restore points or backups in Windows Complete PC Restore.

I have been searching the internet for fixes and have tried a lot, including bootrec /fixboot (as well as /fixmbr, and /rebuildbcd, which all complete successfully), chkdsk /r (which reports no errors), and sfc /scannow which reports that "Windows Resource Protection could not perform the requested operation." Tried to update the volume boot code using "bootsec.exe /nt60 sys" command also does not work, reporting that "bootsect.exe" is not recognized as an internal or external command, program or batch file.

Few things have seemed to help that I have used. TestDisk, helped me to find the missing partition where my OS was located when my computer couldn't detect it before, though I'm not familiar with the program so if there are other options that exist which would be useful besides its "Analyse" feature, please explain. Although finding the partition still did not make my computer find the OS.

A:PC won't boot to Vista tho installed "HAL is missing or corrupt"

Hi, you cannot use the i386 dir in Vista\Seven it does not exist, so you were not able to extract a copy of hal.dll this way. It is possible to extract files from the Vista \Seven dvd, however it is a little involved, not what you need to do anyway.

Since you can access the recovery environment, and have established windows is seen as being on c drive, use command prompt (as you have) and at the x sources prompt type:-

C: (press enter)

Next type:- cd boot (press enter)

Next type:- bootsect /nt60 C:\ (press enter)

Restart your computer.

If it fails to find bootsect you are one of those unfortunate enough to have a version that has this removed ( don't ask me why). Post back and we will go about this another way.

Hi, I've had win7 64-bit for a while now. Recently, whenever I put it into hibernation and then reboot it, I get a "missing operating sytem" error when trying to load windows. This happens 100% of the time when booting from a hibernation, but it never happens from a clean boot. Whenever I get this error message from booting from a hibernation, if I ctrl+alt+del to restart, windows will then boot fine from my hibernation file. I have tried to toggle hibernation on/off to delete hiberfil.sys but that didn't work. I've also run startup repair, chkdsk, and bootrec.exe /fixmbr and /fixboot but none of these worked either. I'm not sure what to do next... anyone have any suggestions? thanks

Hi, my friends alienware laptop has encountered the BSOD. The error reads.
File: \BCD
Error code: 0xc0000034.
I understand this problem can occur from someone not switching off their computer or laptop properly and thus not allowing the boot configuration files to be written properly. I have had this problem before with my own computer but I managed to fix the problem using command prompt. I cant remember the specifics on what commands I used although I remember using things such as, chkdsk and dskpart.
I'll start of with chkdsk, after typing chkdsk and hitting enter I get the following message. "The type of the file system is NTFS. The volume is in use by another process". Then chkdsk verifies files (stage 1 of 3) and everything is fine, then verifies indexes (stage 2 of 3) same again, everything is fine and then lastly verifies security descriptors (stage 3 of 3) which then comes with the following message. "Errors detected in the uppercase file". I then try chkdsk /f which comes with the following message. "The type of the file system is NTFS. Cannot lock current drive. Windows cannot run disk checking on this volume because it is write protected.
Now for the dskpart problem. typing dskpart works fine, then when typing commands such as, "list disk" and "list volume" comes with the following message. " There are no fixed disks to show" and "There are no volumes" I am at a complete loss at this as in my si... Read more

Okay, I have an ATI Radeon 8500 on my Windows XP system, and one day, after my dad had used the computer, the 3D video driver stoppeed working. He can't recall doing anything. So it goes. I think "whatever", downloaded the latest Catalyst drivers, and try to install it, only to get the message "INF Error, Video Driver Not Found" and then "Try to set up your adapter with a standard VGA driver before running setup". I tried googling for info (apparently it's a common-ish issue), but I never found anything that worked. I tried uninstalling anything ATI and then installing, to no avail. I tried uninstalling the error-listed VGA adapter from the Device Manager and then running install which didn't work. Rebooting after that also didn't work (it popped up with "New hardware found" after the reboot, but it couldn't find the proper drivers).

After an unedifying series of adventures I got to which has several drivers for my mobo. I first downloaded (obviously) the VGA driver, and tried to run setup. Unfortunately, after preparing the install, an Error message pops up saying "The system cannot detect the device, please confirm that the device is configured properly and restart the setup program." I then tried downloading the AGP upgrade, installed it, but nothing changed. I also downloaded the BIOS update, since it mention... Read more

A:"INF Error", VGA Driver "Missing" Installing ATI Catalyst Drivers

the radeon is not integrated with your motherboard, and the onboard video has probably been disabled in the BIOS. to install the appropriate drivers for an ATI radeon 8500 card you need to download and install the drivers from ati's website. from there you can download the latest version of catalyst and install that.

My friend's computer seemingly got a virus, since it sent an email to somebody in her email list, on its own. She asked me to take a look.

She had a virus checker, but it had never been updated. So I installed "AVGfree" and ran that. It found a "trojan horse" virus as well as some other stuff that it said should be removed, so I did. I then ran "ccleaner" and it suggested to remove a TON of crap, like 500mb worth of files (she installs dumb stuff on her computer all the time). I removed these files. Then I ran "spybot" and it removed some stuff. I then defragged, which it needed.

So here I am, feeling like a hero, but then I reboot and there's a message saying that "lsass.exe" cannot be found. I cancel this message, and then there's another message saying that "ipwins.dll" cannot be found.

I tell her to just ignore these messages until I figure it out, but then she informs me today that she cannot access her email account on her computer. So I've gotta figure out how to fix this.

Any advice?? Thanks.

A:After virus checking and cleaning, "lsass.exe" and "ipwins.dll" missing

She could try the system file checker : tell her to prepare her XP CD (she'll need it if it asks to replace the missing files), then she will have to go to start => run, and type "sfc /scannow".

If that fails, she can perform a repair install if she has an OEM, retail or upgrade XP CD (recovery CD's cant' do that). She will have to boot on the cd, thus she needs first to change the boot order in the bios to CD-rom first. Then, when XP setup loads, choose the option "To setup Windows XP now" (not the one about recovery console). On the next screen (after the licence agreement) she should be given the option to repair her current xp installation by typing R.

Once that's done, if the CD wasn't a SP2 version, first thing is to go to windows update to reinstall XP SP2 and all updates she could have done since. Don't surf on the internet before any antivirus and firewall (either windows or another) is enabled.

Having trouble booting from Win 7 Pro 64bit install disk (copy of). Keep getting error 0xc000000a ( not sure of all digits)

Info: The boot selection failed because a required device is inaccessible message when attempting boot from recovery cd

Have Acronis 2013 recovery cd, Partition Magic boot cd, and my original and copy of Win 7 Pro installation cd.

Any ideas of what's happening with the boot failure...and is there a log somewhere (if I can get restarted) that would have more details on this error. Any way to trace what is not being found ?


A:How to idendify "missing" device at boot

A couple of guesses:

Boot order problem: go into BIOS settings and change the boot order. It doesn't matter what you boot first (assuming CD-ROM Drive), just change it and reboot, then go back into BIOS Settings and change it back to the way you want it. Test and see if that works.

If all CD/DVDs fail to boot it could be a failed optical drive. You could try to boot from a USB stick to test this idea.

Disconnect all other drives except the CD/DVD DRive and test.

Is there an OS on the HDD? Will that boot?
If yes, then no, try disconnecting the CD/DVD Drive.

Lets see if any of that shakes something loose.

Long story short, my Dell C521 (AMD Dual Core 2GHz with 2GB of memory) was working fine as a dual boot Vista Home Premium and Ubuntu machine (although my daughter only used Ubuntu). One day it stopped booting.

I suspected the Ubuntu partition we created (originally thinking it was just a test) was out of room. So... I removed the HD and tested it off line. It was working fine, but as expected, the Ubuntu partition was too small.

In the process of trying to change the size of the partitions, I "un-mounted" the partition Vista was using.

After giving up on that approach, since I have all the data backed up, I decided just to reinstall Windows Vista using the media which came with the computer from Dell. Unfortunately, however, it will not boot from the DVD.

All I get is "BOOT MGR MISSING". Any ideas?



Have you setup boot order to boot from DVD drive? Try F12 when DELL logo appears so you can choose boot device.

So, the last few days I've been struggling with 2 HDDs that fried after I did some weird connection between them, while replacing my old VGA. I eventually got to save one of them (luckily, the newest one, with higher capacity and the one which I installed my OSs in), with the help of fzakbar from the hard drive support forum (2 fried HDDs?).

After the fix, while the system recognized the HDD, it wouldn't boot. Before the incident it was divided in 2 partitions, one for Windows 7 and another for Ubuntu, and it would boot from GRUB (which would let me choose from the 2 OSs).

In order to save my data, I ran Ubuntu from the DVD, and I was actually able to save all my important files to an external HDD. I then proceeded to download and run "Boot-Repair", which is supposed to fix the boot problem. After that GRUB was working again and I could boot to my old Ubuntu installation, however it wouldn't show Windows 7.

I then tried fixing Windows via its installation disk. The automated repair ("startup repair") didn't work, it would say the version of the disk is not compatible with the installed version (probably because the disk is old). Then I tried using the bootsect and bootrec tools directly in the cmd. Now when the system starts I get the message "BOOTMGR is missing". I can run Ubuntu from the DVD and use Boot-Repair to fix GRUB and boot Ubuntu again, but the problem still persists, it won't find Windows 7. I also tried choosing MGR instead of GRU... Read more

Ok, so here's my situation. I have Ubuntu 9.04 and Windows XP Professional installed on my machine and I'm using GRUB to select between the two.

GRUB is working fine (to my knowledge) and I can use it to boot into Ubuntu fine, but any time I try to get into Windows the screen reads "NTLDR is missing." It's weird because Windows was working perfectly fine a few days ago. It is a brand new install and I haven't put anything on Windows other than Steam and CoreTemp.exe.

I noticed that boot.ini,, and ntldr were all missing from my Windows XP installation. I'm not sure how that could happen. I promptly copied over ntldr and from the install disc and ran bootcfg /rebuild to recreate boot.ini.

I've also run fixboot. I'm afraid of running fixmbr because I don't want to wipe out GRUB.

None of this has made any difference. Could someone help?
