Deleted 100MB reserved partition - BIOS doesn't detect Hard Disk

Q: Deleted 100MB reserved partition - BIOS doesn't detect Hard Disk


I accidentally deleted the 100MB reserved partition while reinstalling win 7 which got stuck and when I restarted, I got 'Bootmgr Missing' error. I have Dell Inspiron N5010 laptop. Now, my BIOS doesn't detect my hard disk and I also don't see any hard disk while reinstalling win7 via bootable USB drive.

Is it that 100mb partition contained the required drivers? If yes, how could I fix this?

Please help !


A: Deleted 100MB reserved partition - BIOS doesn't detect Hard Disk

There are no drivers stored on the SR partition.
The 100 MB System Reserved partition has nothing to do with the bios seeing the hard drive or the Windows 7 installer seeing the hard drive.

I am gonna do a format reinstall of Windows 7 and I noticed this partition which I believe was created when I first installed Windows 7. Should I just leave it there or can i delete this partition when I format reinstall Windows? Thanks.

A:Disk 0 Partition 1 System Reserved 100mb

Yes, and yes. I would normally leave it, but if you delete it the Windows 7 install should just recreate it. It's where Windows 7 likes to put the MBR (and, I've read, some credentials information).

I have two drives in my computer:

Drive 1 (contains Windows 7 x64)
Drive 2 (contains the 100MB reserved partition)

I want to remove Drive 2 and move the reserved partition to Drive 1.

I made a 100MB partition on Drive 1 (shrunk it first). Then I shut down the computer and disconnected Drive 2. Then I inserted my Win7 DVD, started the computer and selected "startup repair". According to the log, it did repair something (I even let it run 3 times). But when I remove the Win7 DVD, the system won't boot. Only when I re-connect Drive 2 (which still contains the 100MB reserved partition), it will boot.

What am I doing wrong? Thanks!

Another question. Do you really want to keep "system reserved"? It's used for:Bootmanager and bootmenu
Bitlocker encryption.
You definitely want bootmanager and bootmenu on a separate partition?

I'm running XP Home SP3 and Win7 Pro 32 bit in a dual-boot setup. I use Macrium Reflect to image the entire boot drive.

Looking at the graphic for Disk Management in both XP and Win7 (shown), I don't see the 100MB System Reserved partition, even though the numbers add up as shown. Shouldn't that 100MB partition be visible? Where would it be located? Between the two main partitions D: and C: ?

A:Where's my 100MB System Reserved partition?

If the drive was already partitoned when you installed Windows 7, it will not create a Reserved partiton.
It will put the boot data, etc. on the first partition it sees.

I did a standard Win7-64 installation on a 128GB SSD and have no problems. My question is, can I merge the 100MB System Reserved partition that the Win7 Installer creates into my normal boot partition. Right now that 100MB is just wasted space and I'd like to get it back into use.

I have MiniTool Partition Wizard and this screen shot shows my current configuration.

My concern is that my system won't boot if I merge the 2 partitions because the new partition starting place will be different from where it is now, and I'm not clear on what to do about Boot Manager or how to get it to point to the proper place.

I do have the MiniTool boot CD and I have verified that this works OK, but I can't find any info on whether or not trouble will happen if I merge the 2 partitions on my boot drive.

I'm in the process of swapping out an HDD boot drive for a new Crucial M4 SSD, and discovered that a 100MB partition I created for "system reserved" files got squeezed down to 79MB by the Acronis cloning software I used. The SSD booted just fine with the smaller partition, and my offset is set to the recommended 1024. Is there any reason I need to be worried about a system reserved partition that isn't exactly 100MB?

I was recently doing a fresh install on my SSD (primary). I saw a 100mb system reserved partition and deleted it thinking it was from the primary drive. But it was from my data drive/secondary hard drive. Now the data partition is there in secondary hard drive but I'm unable to access it. Windows says I have to format the drive to access it, rightfully so.

Is there any way to access my data now?

A:Deleted system reserved partition from my secondary hard drive

Didn`t you even pay attention to what the Disk # was when you deleted it ? Obviously not.

Why didn`t you unplug your data drive before you even attempted the new install ???????

If you format your data drive, bye bye data.

There is no reason you can`t access the data on that drive.

I restored Windows 7 Home Premium (64 bit version) on my PC and I used Easeus Todo Backup v4.0.0.2. to do this. I restored the hidden reserved partition and also the Windows partition (my C: drive). However, the restoration altered the size of both of these partitions. It has reduced the reserved partition from 100 Mb to 99.7 Mb and I'm guessing it must have increased the C: partition and used the 0.3Mb reduced from the hidden partition (I can't remember the original size of my C: partition)?

Will the reduction in size of the reserved partition from 100Mb to 99.7Mb have any implications? Does anyone know why this should happen and should I use a partition manager to put it back to 100Mb?


A:100Mb Reserved partition reduced in size by backup software

No need to worry.

Go to Disk Management and see how much of the 99.7 Mb is used.

Hilast night clean installed windows 7 pro and noticed that system reserved partition is created with 100MB. Then upgrade it to windows 8 pro and finally updated it to windows 8.1 pro.
After complete installation of windows 8.1 pro and noticed in computer management that still system reserved partition is 100MB. whereas if in case i did clean installation of windows 8 pro then system reserved partition will be 350MB.My HDD capacity is 2TB and i have nearly 1TB of unallocated space. C drive is 200GBTherefore i would like to increase my system reserved partition from 100MB to 350MB.How to increase system reserved partition from 100MB to 350MB with step by step ?What is the advantages of allowing 350MB to system reserved partition in windows 8.1 pro?

A:Planning to move system reserved partition from 100MB to 350MB ?

On a Win 7 clean install the system reserved partition contains the boot manager and configuration files, with the system recovery files placed on the OS install partition.
On a Win 8 clean install the system recovery files are placed in the system reserved partition, hence the need for a larger partition.
When an upgrade from Win 7 to Win 8 is performed the system reserved partition is retained at its current size and with the same file placements.
I would be inclined to leave it alone.  If you start moving files and get it wrong, you could end up with a non-booting system.

When I first purchased my Acer AspireOne D255 back in 2010, I immediately deleted Windows 7 Starter and installed a dual-boot of XP Home and Ubuntu. However, recently I decided that I want Windows 7 back on the Netbook, so I ordered Recovery DVDs from Acer.

I would like to set up an encrypted dual boot between Windows 7 Starter & Kubuntu 12.04. I found a great tutorial online explaining how to do this:

[not sure if I'm allowed to post links to other sites]http://

Problem is that the tutorial won't work for me because I don't have the 100 MB System Reserved Partition. I want to follow this particular tutorial because it's very simple, and it ensures that if I switch to a different Distro later I won't have to reinstall Windows 7.

Now I did successfully follow the "Option One" instruction here to use Disk Management to create a System Partition:

System Reserved : Create Using Disk Management

All this accomplished however is creating a small partition that is not active, and certainly not at the front of the disk, and definitely not set as a System Partition.

Please help! I've spent way too many hours / days at this trying to figure this out on my own.

Edit: I have been using the "Disk Utility" in a Lubuntu 12.04 LiveCD to partition the drive...

A:Acer Recovery DVD Won't Create 100MB System Reserved Partition


You should first install Windows 7 in the vanilla fashion - that will create the 100MB System Reserved partition and the usual System partition (usually C)

I'm running Windows 7 Home 64bit on a Compaq Presario CQ61 laptop.
I have a 120GB SSD drive (C) with only Windows operating system and program files.
I have a 320GB HDD drive (D) in place of my DVD drive which holds all my documents.

Following a foolish adventure with Linux which forced me to re-install Windows,
I find my 320GB drive partitions are no longer optimal.

When setting up Linux I reduced the size of my documents partition to provide for Linux partitions.
When re-installing Windows, the installation setup a 100mb System Reserved partition immediately after my documents partition. This leaves a 42GB unallocated portion of my HDD.

I understand that I cannot delete the 100mb System Reserved partition as that is required for boot files etc.
However, I would like to move the System Reserved partition to the end of the HDD so that I can resize my documents partition using the 42GB of unallocated space.

Partition Wizard does not allow me to touch the System Reserved partition, how do I move it?

Thank you,

"system reserved" is not on the win7 physical drive!! Since you have one 1 OS... It is very good thing to move it to same disk as WIN7. even better merge the boot filles and boot menu to the C-drive . Wanna know how?

Special attention has to be given to the restore process of the OS partition if you have a separate 100MB active boot partition. You must not mark the OS partition as ?active? during the restore process nor must you restore the MBR.

Hi there,

I was reading a topic on Imaging Strategies in the BackUp & Restore section of this forum and noticed this above.

I have deleted this small partition off my computer -
Asus EB1501 Intel Atom 330 / 1.6 GHz / Dual Core / 2gb RAM / 250gb HDD / Win 7 Home Prem.

My system boots up with no problem but I suspect that the Recovery Partition that is in place has now been rendered useless. Would that be correct?

A:100mb Partition - Deleted

If you deleted System Reserved and can still boot, then your boot files weren't on it.

Where are they? Possibly on the recovery partition---which would mean it is functioning in some sense.

I've never used a recovery partition but know that they can be dodgy and useless for recovery purposes in some situations.

Can you at least bring up the menu on which recovery is offered as a choice?

Might be a good idea to post a screen shot of Windows Disk Management so we can see the location of your boot files.

So I was trying to install the OS into my 3TB hard drive and after finding the exact same one on sale, I bought another to set up RAID 1. I noticed in disk mgr that my partitions were all messed up (3 total - 350gb, 2.xxtb, and 6xxgb) where I was suppose to select drives to install windows to and I figured I can delete them all and merge it to create one big drive since I had UEFI BIOs and mobo was able to recognize the 3tb HDD. So i went ahead and deleted everything so i can do a fresh install and not knowing otherwise, i deleted the 100mb boot partition or whatever you call it. after my first restart, i got the bootdisk error message with the ctrl+alt+del to restart. Thinking I didnt format it correctly, I took the drive out and formatted it on another computer, now all i get is the ASUS welcome screen with the msg on the bottom to press del to enter bios. I have restarted multiple times and it seems like pressing anything is unresponsive. HOWEVER, after disconnecting the hard drives, I was able to boot from the DVD and get to the Windows 7 repair screen.

Correct title (mods pls fix if possible): BIOS/PC Doesn't detects hard disk

Hi all,

I have a seagate 160gb hdd .. 2 years old.. was working perfectly fine till an hour ago.

I suddenly thought my computer was slow .. kinda laggy.. and i also started to hear some voice (weird voice .. like tak-tak-tak .. as if some thing was knocking on one of the components) from inside my cabinet.

So i switched off my comp ..

I restarted .. the sound again came .. very loud and apparent.

I then realised that at the first screen, one of my hard disk (160 gb seagate) was not detected.

I then took it out (of the cabinet) .. this time i made the hdd stand on the floor, attached the power and ide cable .. turned on the comp .. and NOW i realized the sound was coming from this hdd itself. The sound goes like something spinning inside the hdd .. then it would stop .. then again spins .. then again stops .. then again spins, and so on. This (spinning) sound would also continue even when i turn off the comp (although it then gradually decreases and then goes off, and no i'm not talking about the sound fans make). I'm sure i never heard such sound from my hdd.

Nevertheless .. i kept my comp off for like 30 mins .. and then i re-tested it .. and the hard disk still wouldn't detect.

My current setup is Windows 7 Professional on a 64Gb SSD, and my data on a 1TB HDD; I wish to upgrade my data storage to RAID 5 (via Intel Matrix RAID).

Whilst examining my HDD before I make the change, I noticed that it had a system reserved partition of 100MB on it. After a lot of googling, I had determined that this is used for BitLocker and system recovery, and is not (in most cases) necesarily needed.

However I think that my situation may be different.

The complication is that the system reserved partition is marked as 'System' (as can be seen in the below screenshot), and it seems (from changing boot orders) that the OS actually bootstraps from the 1TB HDD (although it resides on the SSD entirely).

Clearly this is non-ideal (unnecessary coupling of data drive to system drive ect ect).

Does anyone have any experience with this, or know how I could safely migrate the System Reserved partition (or just the MBR, as I dont use bitlocker and have the windows install disks) to the SSD?

Thanks in advance for any replies.

Hey guys, I accidently deleted my system reserved partition

I only have one system installed on my pc, so no dual boot is needed or anything, I think it created a seperate system partition because of a windows.old folder, which has already been deleted now, because it took too much space.

So now when I start up my pc i get the error that my bootmgr is missing.

I tried repairing it by inserting the windows 7 dvd and using the repair, but when I click on windows 7 and i try to repair it it says it's the wrong version of windows. My language settings are set correctly so that's not the problem.

I then tried to do it by pressing shift + f10 to get into the command line and using the following commands:
Bootrec.exe /FixMbr
Bootrec.exe /FixBoot
Bootrec.exe /ScanOs
Bootrec.exe /RebuildBcd
however the scanos and rebuildbcd can't find any windows installation..

If i put in my windows 7 dvd and i startup my pc, it works fine, because it then uses the bootmgr from the win7 dvd. So I thought, let's just copy the bootmgr.exe to my windows. But this didn't work either.

So how do I fix my problem? Is there a way to create a new system reserved partition with the correct bootconfiguration?

I've been surfing through the web but couldn't find any other solutions

Trying to do a clean install and my Windows 7 Home Premium x64 seems to have an aversion to putting the system reserved partion on disk 0. My HP notebook has two identical disk drives. If I boot up the windows install with both drives unallocated and do a custom install, the window where i select the partition for the install if I click new to create a partition on disk 0, it creates one partition on the whole disk. If I do the same for disk 1 it automatically creates two partitions, one for the system reserved. If I try to do that in reverse order by partioning disk 1 first it will still create two partitions on disk 1 (one for the system reserved). It wont partion disk 0 with the system reserved partition.

I tried to install windows with only disk 0 plugged to into the motherboard and that worked when i partitioned the drive during the windows install it created the system partion on disk 0. However once i had windows up in running, I plugged disk 1 (unallocated) back into the mother board and windows woudnt boot up.

I could jsut install windows on disk 1 but ive read that it is better to install it on disk 0.

I have made serious mistake. I have deleted system reserved partition and all files with it. Worst thing is that it is my company laptop, and i have a lot of stuff on it.

A:Windows 7 system reserved partition files deleted


Please download "Partition Wizard" bootable CD from the below link and boot from it.

Partition Wizard Bootable CD allows user to manage partition directly with partition manager bootable CD.

Then use a digital cam or smart phone to take closeup shot of the screen and post it with next reply.

Hard drive is encrypted so i can't restore anything.

This will make everything difficult. If full disk encryption is used, recreating boot files won't work. Most of the full disk encryption like "Symantec Endpoint Encryption" write custom code to the MBR. Overwriting this with a standard MBR code will make things worse. partition need to be recovered without modifying the MBR code.

Do you know which encryption software is used ?. What was the reason for deleting the partition ?.

Do you required to input a password before beginning the boot process ? (Preboot Authentication ).

I'm installing Windows 7 on a new SSD, and using the old Windows 7 HDD as an extra drive. Installing Windows failed the first time (corrupt file). When I went to install it the second time, I accidentally deleted both the system reserved partition and the main OS partition on the OLD HDD, instead of the new SSD like I wanted to do. I immediately cancelled the installation, but it was too late. Now when I plug the old HDD into another machine, the whole disk is unallocated. Is there any way for me to repair the partitions, or at least get the data off of it (like I should have in the first place)?

After some searching, it seems as though most people delete just the system reserved partition, not both like me. I've tried some of those solutions but they don't help.


Edit: obviously, I didn't search hard enough: I accidently deleted a needed partition and now it is 'Unallocated'.

Background information

My laptop is a Toshiba Satellite L50-B with Intel Core i7 and AMD Radeon R7 M260. It came with Windows 8 pre-installed when I first bought it, but I soon wiped the disk to install Windows 7 instead. I also installed Ubuntu on a separate partition so I could dual boot. So the GRUB bootloader replaced the MBR. This isn't the issue though, just want to inform the laptop is running in CSM mode(or legacy) instead of UEFI.

First of all, before you assume, the hard drive is working perfectly. I can still boot to Windows and it works fine. More on this at the end.

Now the issue is, I removed the Ubuntu partition, and I've really no idea what I did wrong with restoring/fixing the MBR. Now, whenever I try to boot, it displays "No boot device found". I've tried:

- Windows Recovery
- Windows Recovery using disk
- Parted Magic (Hiren's BootCD)

Mainly, I tried to restore and fix the MBR using bootsect and bootrec (fixmbr, fixboot and rebuildbcd). Also automated repair using the recovery.

As I mentioned above, I don't think it's a problem with the hard drive, since I'm posting this very question from this problematic laptop, on the main Windows installation.

I can still boot into windows, but only using either:

- Windows recovery disk (without booting into the disk, just have it in

In the past I used Norton Ghost 2003 to create images of my installation to allow me a very quick reinstallation of Windows and the most important programs. I might retire NG 2003 and instead use DriveImage XML. In any case, Win7 creates a new partition "System Reserved" (100MB) but DriveImage XML does not see it for backup. Do I need to image that or is it enough to image C which I could play back on a newly partitioned HD, i.e. "System Reserved" is missing? What is that partition for anyways? Note that I have Windows 7 Home Premium.

A:Disk Image & System Reserved Partition

Hello hama, welcome to Seven Forums!

The Windows 7 created "System Reserved" partition is where the boot files needed to boot/start Windows are stored and if it is not included in a created image of Windows 7 you will not be able to use that image and Windows 7 will not start without doing startup repairs to create new boot files to the re-imaged Windows 7 partition.

This appears to be your MSR partition (apparently created in Win8/Win8.1 install before upgrading to Win10). Should not have a drive letter at all.

I'm trying to move a System Reserved partition from Disk 1 (failing) to Disk 2.

I recently had to purchase a new hard drive after receiving a "S.M.A.R.T. bad backup and replace" message upon bootup. However, I've been unable to get rid of my failing hard drive (Disk 1) because of the System Reserved partition (or I at least believe that may be the problem). If I physically disconnect Disk 1 I get a "BOOTMGR is missing" message, regardless of the BIOS boot order.

Long story short:
I want to retire my failing hard drive (Disk 1) and have only Disk 0 and my new hard drive (Disk 2) installed in my computer.

If possible, I would like a step by step procedure (I'm quite the layman in this area).
I've also already copied all the data I wish to keep from Disk 1 -> 2.

Hi All,

Somehow I have ended up with two system reserved partitions. I enclose a screenshot of my disk management screen.

Disk 1 is my primary Win 7 boot drive... Because of this I am assuming that D:/ which is the system reserved partition on that drive is needed.

However, disk 0 is just a backup I disk I use for data, music, videos etc..etc.. but somehow it seems to also have acquired a 100MB system partition (may be due to the fact that I used to have a dual boot linux setup).

Anyway, I am thinking that I can probably delete G:/ the 100MB partition on that drive. The only thing that worries me is that it's listed as 'active' as is D:/...

Also, should my main C:/ be made 'active'.

Help appreciated. Thanks.

I have a brand new SSD that I just installed Windows on using an Ultimate Upgrade Disk and followed the "Clean Install using an Upgrade Disk" tutorial on here, and also the "Relocate Users folders during Windows 7 Installation" tutorial after Windows was actually installed.

According to the first tutorial the Windows install SHOULD have created a system reserved partition since the whole SSD was unallocated space, yet it did not.

Now I DID have Ubuntu installed on another HDD which had a partition marked as Active, and for some reason one of my other drives was also marked as Active, since I reinstalled Windows I have now removed the Ubuntu Partitions and I have now set the other drive that wasn't meant to be Active, as Inactive, and set my "C" drive which is marked as Boot, as Active.

However before I go about reinstalling MORE software (so far just Flash Player and Antivirus software), I would rather format C and reinstall again if it would properly give me the 100Mb System Reserved Partition that is so useful when Windows breaks itself.

So can someone tell me by looking at the provided screenshot of Disk Management whether another fresh install will actually create the 100Mb System Reserved partition that I want on my drive.

A:Lack of 100Mb System Reserved

Your system files got written to Disk 1 because you did not unplug all other drives and it was marked active when you did the install.

You do not need a SR partition.

Re install windows and this time unplug all the other hard drives, if you want a SR partition just delete the drive to unallocated space.

I want to merge the 2 partition(F and G drive)
And How can i recover the Lenovo Softwares if the OEM Reserved is on the External Hard Drive.

My External Hard Drive is the Hard Drive of my laptop before.

A:How to merge partition and use the OEM reserved on External Hard Drive

First you want to back up all of your data. Never play with partitions without doing this first.

The OEM partition could be imaged (using disk imaging software) to back it up and save it, but I wonder if it would work from an external drive? It would have been better to use the utility to burn recovery CDs of that partition while it was still in the laptop.

Then, to make this easy, you want to get a copy of Partition Wizard for bootable CD. (This is because Windows Disk management will only work to the right, it won't expand partitions to the left).

Using Partition Wizard you will delete Test F: and then expand H: to the left into that now unallocated space.
Since it is only 199MB you could just stop there. But if you wanted to add that to G: you could.

I've been using a Dell Dimension 4100 P3 1 GHz for a couple of years without problems.

Since it was a SeaGate hard drive, I used SeaGate's online scanner to scan it for errors because I suspected it was faulty. I also did some virus scans. I restarted a little while later, and the Dell computer would get stuck on the Dell post screen. It wouldn't even go into BIOS after I hit DEL (it would freeze).

A few days ago, I tried installing an OS (windows Vista) for the first time on my computer. It was previously running win XP.Now, while I was installing win Vista, I had to choose a different drive than the one having XP due to storage issues. I managed to install it without further problems and it worked really smooth.Then I felt that I had no need for Win XP so I deleted its WINDOWS folder from the drive it was in. But while rebooting, the BIOS menu still asked me to choose an OS between XP and Vista. I then searched the internet and found out that removing an OS from the dual boot menu was more difficult in win Vista than in XP. (In win XP you could just modify the boot .ini file.) So, I instead decided to decrease the time the dual boot menu showed, to zero. While I was doing that, I am quite sure I set the default OS to Vista. But while booting, the BIOS simply selects win XP in a split second (because I set the time to zero). Windows Vista option is still there but I can't select it. Then it says 'drivers not found' (because I deleted the win XP folder). I have an AWARD BIOS and I tried pressing F8 while booting to open Windows advanced boot menu, but strangely, it does not show Win Vista. I don't know what to do. Prior to this I saw that my C: drive (with win XP) was my active drive and my F: drive (with win Vista) was my boot drive.PLEASE HELP!

A:BIOS doesn't detect OS.

Try tapping F8 before windows would normally start to load. That should bring up the boot menu but I think it will be the XP menu since that's your default OS. But give it a try and see if it allows you to boot to another OS.Or, if you hit the PAUSE/BREAK key at just the right time to pause loading at the OS selection screen you can select Vista at that point.If you can get Vista to load then you need to run BCDEDIT or a third party application like EASYBCD to edit the entries.If neither of those work you'll probably have to either do a fresh install or run BCDEDIT after booting from the Vista disk. From:"BCDEDIT works from installation boot dvd too. If you mess up with a setting and you cannot boot, just boot from DVD and enter Repair Computer, then go to command prompt and there you go. You can play again with bcdedit to restore your system back."More detailed info here:

I just won a new Intel SSD in a contest. I removed the old SATA hard drive from my laptop and plugged in the new SSD. I turned on my laptop with a Windows 7 installation disk inserted, booted from the Windows disk, and got the screen where it asks which drive to install Windows onto. It said there were no drives detected.

Then I restarted the computer and went into the BIOS and tried to do a "Hard drive diagnostic test" and it said "Hard drive not exist." The SSD also does not show up in the list of bootable devices.

Next, I put my old hard drive back into my laptop and put the SSD in a USB SATA hard drive enclosure. I plugged the enclosure into a USB port and loaded the BIOS again. I looked at the list of bootable devices and the SSD was listed. Then I loaded Windows. Windows did detect the SSD in the Disk Manager and from there I formatted the SSD. Now I am able to see the SSD listed in My Computer as drive "I".

I tried replacing the hard drive with the SSD again and the BIOS still will not detect it. It only detects it when it is plugged in through the USB enclosure. What do I need to do to get it to detect the SSD normally (plugged into the SATA cable inside the laptop)?

A:BIOS doesn't detect HDD

Thanks for the reply, but I had done that already. I loaded the default and the custom setting, and neither did anything.

Now I don't even see the hard drive listed in the post-POST screen. I immediately see "insert boot diskette." I removed the floppy drive and it still says it, although it waits a little bit longer with a blinking cursor before the message pops up.

I did try a different HDD (through the ATA controller card) with the computer and it still wasn't detected. I then tried attaching this HDD (20GB) via an IDE motherboard slot (the other one is occupied by the CD-ROM). The HDD was not detected in BIOS, but the CD-ROM is. Then, I removed the CD-ROM from its cable and attached it to the same IDE cable as the newly-connected HDD. Still no dice. Finally, I switched both devices (now on the same 80-pin IDE cable) to the motherboard IDE slot that the CD-ROM drive was originally attached to. BIOS detects both the HDD and the CD-ROM drive.

I've never seen or heard about a virus that infects a BIOS from a hard drive. I really wish I knew what the source of my problem is. I think it's really odd that my hard drive on one computer would get Windows corruption (the one I was scanning with the Dell; other files are still intact), then the CD-ROM on another computer fail (the one in the Dell), and then a motherboard IDE slot stop working, completely independently on the same day.

Okay, to begin I have searched the forums and I'm not a noob to troubleshooting however this has got me stumped.

I downloaded the Vista Recovery disk( since i have a toshiba Laptop which doesn't have the actualy Vista Install disk. Burned the Iso to a bootable cd and got the cd to boot up.

I click on repair and then i'm sent to a screen that asks me to select the Hard Drive/Operating system to repair from however there is nothing to select. There are two options next and load drive. I clicked next with nothing selected it did a repair but no luck (tried this twice) my guess is because the repair essentialy did nothing as it didn't detect any hard drive to save the bootmgr to. However under the load disk section which is what i think i should be using i have no idea what to select. Any ideas?

Hi there,We just received  a shipment of Elitebook 840 G3s.  I wanted to clone my current Folio over to the new laptop but was surprised that when I booted into clonezilla from a 4GB USB Kingston Data traveller that it didn't see the source 256 GB USB SSD Drive.  When I went into the BIOS, it doesn't see the USB Drive, but it does see the thumbdrive and internal SSD. I have tried USB 2 & 3 devices with different drives attached.  The drive is detected when booted into windows and I can browse it. Is anyone aware of an issue with the current 1.05 BIOS and eithe drive size etc... recognized by the BIOS for USB?

Hello, I have started the installation process of windows 7 on a clean 1 TB hard drive. In order to ensure expediency of the read time of my primary drive, I choose the custom installation. When I did I partioned the drive as 250GB & 700GB. Hoever it also created a 100MB system partition on its own. It never did this in Vista. Is it suppose to do that?

A:Installation: Partition - why a 100MB system partition

100mb SysReserved contains the boot manager and the same tools which are on the Install or Repair disk Repair My Computer console, however this partition makes them available on Advanced Boot Tools via tapping F8 at bootup. System Recovery Options

It can be removed but should not be unless it creates a conflict. It will require marking Win7 active and running Startup Repair up to 3 separate times with reboots to recover after removing it.

I want to do a complete reformat. I have a Windows XP Setup CD, and I backed up all my desired files onto an external hard drive, but after starting the Windows XP Setup (Full Install, not Upgrade) in Safe Mode (regular doesn't work) and having it reboot and continue trying to install, I get a blue screen with a 0x00 type code. Is there any way to tell the computer to completely reformat the hard drive (2x500GB set up in a Mirror Array, in case one hard drive has a hardware fault, I'll still have the data on the mirrored drive) so that I can install Windows XP all over again, with none of the problems that I'm trying to get rid of? If I insert the Windows XP CD and select to boot from CD, it claims I have no hard drives installed and can't continue. The hard drives are in there, but after getting rid of malwares recently, my computer has gone through several stages of problems, and all I want to do now is reformat and start fresh and free. How do I get my computer to recognize the drives in its pre-OS state, so I can install Windows XP on it?

I'm using a Gigabyte GA-EP35-DS3R motherboard, and my hard drive is a seagate barracuda 500gb.

The system is brand new, built myself. No previous operating system on it.
I tried installing windows vista. I get past everything, until it asks me to select a drive to install to, and the list is empty. I tried every driver on the mobo's cd, and every driver on their website, none of them worked. I've tried different SATA modes, and ports on the mobo, and it doesn't work (I would dear say I've tried everything, except another OS because I don't have access to one).

However, when I select browse to search for drivers, when installing vista, I can select the local drive and search it for drivers. Does this mean it's there and it's something else, or is it just an option and what not? (there's a floppy there too, but I have none installed on the computer).

My bios sees the HD just fine. I'm out of ideas, and friggin fed up. I tried contacting Gigabyte but that was pointless.

My motherboards is M5A97.
I was in windows 7 home prem partition and os, preparing partitions to install win7 pro.
I went to Disk Management and deleted a non-system (logical partition). It was taking forever (over 10 minutes) to delete that partition. I then tried to open C: (where windows 7 home premium is located) adn it was taking forever to open that partition.

So I restarted.

Now it boots to the 'Press DEL to enter UEFI BIOS settings' and doesn't go beyond that. I can't even enter BIOS!! WTF!! Help!

My life is on that hard drive. I have already been devising ways to salvage all data from that hard drive which is 100% imperative.

Let's see...before deleting the 200gb logical partition Disk Management said that that is used by other services. I still deleted it (and then it took forever, and restarted and now this).

I have unplugged all USB peripherals except for keyboard.

Any Ideas? Please help. Not being able to enter BIOS is odd.

My hunch is maybe 'partially deleting that one partition, 'vari') may be making the startup extremely slow or snagged.

Now, another very odd symptom is the keyboard lights (showing the enter del for uefi bios screen) only illuminate for 1second when I press a key on the keyboard and then they turn off.

WHAT THE HECK is going on? How do I fix this? I need my computer to operate.


A:Motherboard not Loading BIOS - Deleted a Logical Partition

A:BIOS won't detect IDE Hard Drive

Hi there
Looks like cable or connection is defective. If these are the "Old fashioned" IDE drives check that the ribbon connector is of the correct type -- I believe there are two sorts -- the older version and the newer Enhanced IDE with 40 pins.

Check that you have the correct ribbon type connector for the Mobo. Also connect if the Slave / Master / Auto switch on the HDD (or jump pins on the Mobo if there are any) are correctly set.

Note also at BOOT - ensure also that AHCI in the Bios is correctly set as well -- otherwise the machine will fail to boot.

You really need to set it to IDE for using IDE Disks -- If this has changed from what you were using before you will have to re-install Windows.

You are actually better off getting away from those old fashioned IDE Disks if you can.

It's also possible you might in the Bios have to set the IDE Disk to LBA mode -- to complicated to explain here but notes on this should be available in the documentation that came with the MOBO in BIOS settings.

I had a strange technical problem very recently. I rebooted my PC and it would no longer detect my hard drives. I recently installed a new external hard drive and that could be detected. I tried a few things such as booting from Linux but the strange thing was that the problem seemed to fix itself. I booted my PC a day after it happened, after much worry, and it was fine.

Here are my specs:

Motherboard: Asus AV8 Deluxe
Processor: AMD Atholon 64 3500+
Graphics Card: Saphire Radeon x1600 Pro 512MB
x2 Sata 250GB Hard drives and one external 500GB hard drive

The only clue as to why this happened is in the system tab of the event viewer utility. From about Christmas day onwards I kept getting events of the 'warning category' the problem being number 51. My concern is that I am still getting such events.

I fear it will take a modern Sherlock Holmes to figure this one out.

WARNING!! this will destroy all data on the selected hard drive!! be very careful when selecting a drive to wipe that you don't inadvertently select the wrong disk. After a low level format, unplug the drive, plug back in, windows should detect as a new, virgin, drive and it'll prompt you to format it. Format it and hopefully everything will be fine from here on out for you.

Hello everyone. Not sure if this belongs here or in the hardware forum, but here goes.

The hard drive in my Dell XPS 1640 laptop failed, and so i bought a new one and was planning to do a fresh install of Windows 7. What I thought was, I'd take out the old hard drive, put in the new one, and install Windows 7 off a USB stick.

Removing the old and installing the new went as expected, but when trying to install Windows, no drives were found. I went back into the BIOS and saw that the new drive isn't being detected. Was there another step I needed to take? I assumed I just install the new hard drive just the way the old one was installed, same screws, same connector, etc., and it would work. Apparently I was wrong. Can anyone help? It must be something very basic and obvious that I'm doing wrong.

I've got a problem restoring Win7.

I have 1-year old asus with a 320 seagate disk that has shown "clicks of death" a few times. I got a hitachi 160Gb as a replacement but Win restore will not recognize this disk (To avoid warranty-replies: sending it in for warranty costs more than a new disk and they will probably not find it faulty since the click is there occasionally).

I tried making a backup of c:-only (abt 75Gb, deleted the d:-partition), tried setting the interface to ide instead of ide->ahci, tried using diskpart-clean before restoring but nothing works.

As a bonus the asus-recovery-DVD will copy itself to the HDU, but on reboot (press F9, took me a couple of hours to find that one) it will error "can not open file c:\recovery.dat".

I'm close to installing linux, if it were not for canon not supplying a linux-driver for the scanner.

Is there any solution (besides hoping the seagate won't crash)?

A:Restore does not detect new hard disk

I would try the Hitachi as a stand alone drive to see if you can get the system to recognize it. Load your OS on it to verify it boots properly. Once this has been verified to be good then place it back in the second drive position and plug the Seagate back in and reboot. If the Hitachi is not recognized at this point it is not willing to play well with the Seagate in the Drive 0 position. I don't know is you have a Drive 0 with a Drive 1 as Slave or both drives are Masters, i.e. Drive 0 Master with no slave and Drive 1 Master with no slave.

A:setup can't detect hard disk

According to the report, you forced the conversion of Windows partitions to Dynamic Disks on "sda" by creating too many partitions. I don't think you are going to be able to fix Windows until you remove the Linux filesystem partitions and convert the Dynamic Disks back to Basic Volumes.

Hi, I realized that my usb 3.0 external WD hard drive gets disconnected upon an attempt to transfer files into or out of it. Tried connecting a usb 2.0 external WD hard drive and it worked with no issue. Worst off, the 3.0 drive was unable to be detected by the computer although it is rotating with its light indicator ON. I have tried various power management adjustment based on a google search. But the problem still persists. Any advise? Thanks.

Need advice !!

I have just replaced my 8.4 gb( seagate )hdd with a 40 gb (samsung) hdd. The replacement was due to bad sectors on my old drive.
Now when I installed the new 40 gb drive the computer wouldn't detect it , I did jumper changes on the hdd and finally with a setting I got 32 gb. I have partitioned my hdd equally into c ' and d' respectively.

The manufacturers website gives me information ,about how on some motherboards the hdd doesn't detect more than 32 gb and they have also given a downloadable program with the help of which I can use the full 40 gb.

Now I have installed all my programs and software on my present 32 gb config and to be honest 32 gb is more than enough for my work and I am not in a frame of mind to format and reinstall everything all over again .

Now my question is that , Is there a possibility of some damage or bad sectors creeping into the balance (40 -32 ) 8 gb area which the computer doesn't detect? Since scan disk will only scan the 32 gb capacity and leave the 8 gb unattended.

Kindly elaborate and give me a detailed reply.

first of all i would to thanks this website for having this kind of oline learning for computer troubleshooting and repair. as a newly member of this technical cyber society, i appreciate this opportunity to be with you guys.

i got new laptop with vista preinstalled in it. because some of my programs that i usually used is not running on it, i decided to replace it with xp. but during the setup process, setup cannot continue. it always give me this message: "Setup cannot detect any hard disk......." i'm using windows xp pro sp2 bootable cd. this error will come out in the same part of the setup process ( when setup tells you to Press Enter to continue setup..) as i've tried it for several times.

i hope to receive comments about this problem and advice to solve it.

Welcome to TSG

there's no native support for SATA controllers in windows xp


1. set your SATA operation mode in the BIOS to NON-Raid/IDE

2. press F6 when prompted to install 3rd part drivers and insert a floppy disk with the drivers.

3. slipstream the appropriate drivers into your XP installation CD (i would recommend nLite)
