Windows XP dual-boot and OS drive letter assignment

Q: Windows XP dual-boot and OS drive letter assignment

In a dual boot Window XP system I'd like to be able to have multiple operating systems yet have drive letter C: assigned to the system I select during boot up. The reason is that I want to build multiple systems by building 1 then cloning it to another partition instead of taking the time to build another system. I guess I could have multiple primary partitions on a single drive then just change which one is active. But what if I have 2 hard drives and I want to change which 1 get the C: drive letter. Is there some way to change the hard drive priority? I don't recall that in my BIOS. I'm just trying to save the time and effort of creating and maintaining multiple operating systems.

I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

You can download it direct from this link http://downloaddap.org. (This link will open the download page of DAP so you can save a copy to your computer.)

A: Windows XP dual-boot and OS drive letter assignment

You can clone a system to another Drive and if there is no other HDD on the computer, it will be C: drive(ex) you have 2 HDD's that are the same size. You have Windows and all your applications, drivers and updates on Drive 1. You clone drive 1 to drive 2. Now if you unplug Drive 1, and boot the computer, Drive 2 becomes the C: drive. Plug drive 1 back in, and boot the computer and if Drive 1 is the first HDD in the boot order, that will be C: drive and Drive 2 will be the D: drive.
For your scenario, you can make a Clone Image of Drive 1, and use that same image to clone to several HDD's.

So I've been playing around with my computer which has two internal hard drives - I installed Fedora on the secondary and that's been all fine. Then I used Darik's Boot n Nuke to wipe my main drive clean and I installed a fresh copy of XP on it.

For some reason Windows setup has sort of randomly assigned letters to the drives; e.g. The secondary drive that boots Fedora was called F in Windows but is now C - and the drive that Windows installed on named itself G (it was previously C of course).

When I chose which drive to install on I noticed setup was assigning these letters but didn't see a way to change it at the time and didn't think it would matter. I read somewhere here earlier today that the boot drive really should be named C and it will cause problems if it isn't.

The thing is, both Windows and Linux are operating fine; I've installed several apps and drivers into XP and with no problem.

Will having XP on G instead of C cause me problems down the road? I don't want to get knee deep in reinstalling all of my drivers and apps to find out I'll have to go through it again...

A:[SOLVED] Boot Drive Letter Assignment

Hi bdemonbr,

I presume that when you reinstalled Windows? you still had the secondary Drive connected...

The only way that you will be able to get Windows? back as the C: Drive is to either try booting it without the Fedora Drive connected, and see if it will revert back to C: on boot up...if not, you'll have to use "Boot N Nuke" again and start afresh...This time make sure that the Fedora Drive is disconnected.

In the event that Windows? does revert the "Windows?" Drive back to C:, you will need to connect the Fedora Drive as a 'Slave' so that you can reallocate its Drive letter.

Kind Regards,

Hey Guys,

Heres the issue. I recently did an install of XP home on a new HDD for a customer after their drive went dead. Not realizing, the install mapped the boot drive to F instead of C. Customer called up complaining that he could not install programs, etc... I wanted to go back and change the drive letters through the registry, but after doing some reading, found that changing the system drive letter after install will make windows act screwey, sometimes not even allowing a boot. I personally can live with a diff. drive letter, but the customer seems to not be able to.

I have read one or two posts about using XXclone to clone the system drive to a new partition mapped to C, then deleting the F partition. As i have never used this program or method, i am a bit skeptical, and/or lost at the same time. What do you guys suggest as the best method to change this drive letter and not disrupt the operations of the system?

Thanks in advance for the help

Hi all,

I have two copies of XP installed, one will be stripped down for audio use (Audio OS), and one for general use (General OS). When I boot from the boot manager list into my audio OS, and go to disk management, the drives are setup as I expect:-

C: Audio OS D: General OS E-L My other partitions

When I log into my general OS, the drive letters are muddled:-

C: Audio OS L: General OS Other Drives: not in order

Here, I expected General OS to be on C: (as I am booted into it) and the Audio OS on D: Would this be right? How do I go about swapping L: to C: and C: to D: without causing boot problems?

I have already tried this once by changing the names in the registry
(HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices) but this went wrong and wouldn't allow me to boot into the general OS anymore.

I am now back to the stage where I was before it all went wrong and am really nervous to change anything!

Some guidance would be really appreciated

Many thanks


A:Windows XP (x2) dual boot drive letter confusion

You can't.
You are always booting to 'Audio OS', no matter which you choose. It will always be C.

An alternative would be a 3rd party boot manager. Some hide partitions, so the present OS will always be C.

Hi guys,

I've got a problem with my dual boot setup:

I've installed win8, selected an empty partition, booted it, everything peachy.

The only surprising thing was that driver letters where switched: my windows 7 install and data was now in D: drive and windows 8 install appropiated C: letter drive without consulting me.

This became a problem came when I tried to boot windows 7 and an annoying startup repair assistant showed up.

Tried autorepair but no luck. [to be honest, I let it unattended and don't know what happened, don't even know if it finished since the battery died, but it lasts at least 2 hours, and that should be enough, right?]

Then read somewhere changing active partition to win7 could help. Bad idea: now no boot at all.

After a failed attempt to autorepair with windows 8 dvd restore utility I managed to restore windows 8 dual boot menu with win8 install dvd -> repair console -> bootrec /fixboot bootrec /fixmbr and bootrec /rebuildbcd commands, but windows 7 is still not loading: it says it can't find winload.exe or it is corrupt, and I guess it has something to do with the fact that it is now in D: drive

I installed a new disk into a machine and left the old disk as back up. I set the new disk to master and the old disk to slave. I then used ghost and took an image of the old disk and put it directly onto the new disk. Here is the problem.

The old disk maintained the C and D drive letter and the new drive with the system partition is G. I can play with the registry to change the system drive to C, but this will create several problems.

If I take an image of the new disk and then reapply it without the old disk in the machine which is using the C letter assignment used by windows, will the disk get the correct letter assignments? If this works correctly, it should also update the shortcuts and everything.

A:Drive letter assignment


Here is the problem. You can't change the disk you are booting from, so you have to do a work around.

For example, if you can boot (don't know if you can) from the D drive and have the old disk in as slave, then you can probably change the old drive to maybe F or some unused letter. Then put that drive that you changed to the boot drive position (boot from the F drive) (assuming it keeps that letter you assigned it) With the new drive (now D) in as a slave, you can assign it an unused letter like C:, then when you put it back in as boot drive, you have accomplished what you want. Long process, but it works most of the time. I assume you know the process of changing the letter assignments, but if you don't let me know.

Don't forget, you have to deal with the boot drive in BIOS setup also so it selects the correct one to boot from.

Hey everyone! Here's what the situation is:
I have a brand new hard drive. I set up a Dell Utility partition using the disk from Dell. Once that was done, I installed Windows XP Home on the unallocated partition. Everything set up just fine, but now the hard drive doesn't have the letter assignment I want. If you do the DISKPART command, the partition with Windows on it shows as C. When you boot your system and actually use Windows though, the hard drive shows up as I. Why don't they match? I want my drive to be C. What do I need to do to change it to C? I know I can't use the disk management tool because of the whole system volume thing.
Would I need to use the Windows Repair or the full installation? I have not added any programs to the computer because I wanted to get this issue resolved first. I saw instructions on Microsoft for "How to restore the system/boot drive letter in Windows". It says you shouldn't use it unless the drive somehow changed names on its own. I don't know if it's safe to follow or not. The instructions were at: http://support.microsoft.com/?kbid=223188
Please help. I want to be able to get my desktop up and running again. Thanks in advance.

The only guarentee of resolving you delemma would be to format and Reinstall Windows. That can be alot of work, but if you're having system issues and such, wiping the drive and reinstalling windows should resolve most id not all of the problems.

2 questions:

1. I inserted a Cruzer SD drive into an open USB port. The computer assigns the drive the letter K. I wish for the drive to be assigned G. The Cruzer is already in the uppermost of two USB ports. Is there a way I can force XP to call the Cruzer G instead of K?

2. Someone had apparently inserted and removed a USB flash drive several times on this same computer without properly closing and ejecting the device. As a result, XP had cycled through the alphabet to the next available letter. I had set a third party backup program to go to a particular drive letter. I know that I could (and did) reboot the computer allowing the computer to recognize that the drive letters it thought were in use were not and for the computer to then reorder all available drive letters. However IS THERE a way to force XP, without rebooting, to reset available drive letters? Clicking on my computer in explorer and hitting the View/Refresh does not work.

A:USB Flash Drive assignment letter

You can reset them yourself manually, using Device Manager. If a letter is already in use, you cannot use it...unless you change it to something else that is not in use.

I start at the end of the alphabet and assign drive letters to storage partitions. C: is the system partition by default, D: is the optical drive by default...anything between D: and the latter characters of the alphabet will be assigned letters E:, etc.

Aside from doing a repair install or something similar...I don't know of a way to force an automatic reassignment of letters.

Hi there,

I installed Windows 7 to test it on my PC (I still use XP for most purposes). Now I want to reinstall it because I want to try a different version. Unfortunately, I would have to re-assign all drives again and I have a lot of them.

So my question is this: Is there any way to save the current assignment and restore it when I have reinstalled Windows?


I got access to MSDNAA through my university account. Not that that's relevant to this question ;-)

A:Save drive letter assignment?

The easiest way might be to open Regedit, navigate to the HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices folder, make sure the MountedDevices folder is highlighted on the left, then do File->Export and save the registry keys somewhere. It should save as a .reg file. Upon reinstallation, just double click on the file and it should import them back to restore the settings.

Make SURE after you export the keys to verify that they were all saved and reflect what is currently in the registry by right clicking on the saved .reg file and opening in notepad/wordpad.

I believe this should work.

My laptop computer has a built-in card reader for Memory Sticks and SD cards to which Windows 7 assigns two drive letters. As I never use the Memory Stick reader I would like to use the drive letter assigned to it for one of the partitions of the hard disk. The problem is that the Memors Stick reader does not show up in Disk Management as long as it is empty - and I haven't got any Memory Stick. How can I re-assign the card reader's drive letter although there is no Memory Stick inserted?

Hi all. Cloned my main HD [C:] to my new hard drive, which was detected on my system as [F:]. All went well, except I encountered a small problem and did a Windows XP Repair Install.

Now, my problem is, I removed the [C:] drive and booted from the [F:] drive as my main drive was failing. However, all of my programs are not working because of the fact the drive is [F:] and their roots still say the files are on [C:].

So, I go into Disk Management and attempt to change the letter of F: to C:. However, Windows tells me "Windows cannot modify the drive letter of your system volume or boot volume."

I need this drive to be C:. Anyone know how to bypass this at all???

I am facing a really strange kind of problem with my system.

I am a total newbie when it comes to Win 8. A couple of earlier attempts resulted in frustration with GUI and simply gave up. Now I have a good size order for PCs on hand, win 7 licenses are no longer available so have to go with 8.1

My client can get hold of enterprise version licenses at a very reasonable price so was trying out to learn to setup the systems the way he likes and needs. Somehow even after 4 attempts I can't get it to work the way I want.

I have 2 Seagate drives, one 2 Tb and one 750 GB. 2 x 4GB memory chips, Intel DH77EB motherboard and i3-3220T processor.

The initial problem was of data corruption and had to turn off the fast boot feature in power settings. The next problem is very difficult to solve.

It does not recognise even the NTFS volumes in the extended partitions. When it does it won't allow read or write access. Even if I change the permissions it won't retain them. It keeps changing the assigned drive letters to USB attached drives even when I attach them one at a time and assign proper letters that I want it will juggle them around randomly after the next boot. The missing volume phenomenon occurs even with the USB attached drives.

Every time I do a fresh install it comes up with totally different set of permissions about accessing the drives. The files and folders I cansee and access from Win 7 OS are too often simply not visible.

Hi All

First post here.

This is the system that I used to have. An SSD with XP32, and another HDD with Win7x64. I first started with XP and then later installed 7. When I installed Win7 it called the partition that it was installed on "C:" (even though the XP installation claimed its partition to be C. I set up a BCD (on the SSD) to allow me to boot into either XP (which I believe it did by looking at the boot.ini on that drive) or to boot into Win7 using pointers in the BCD? (I am not so familiar with how BCDs and MBRs work). So long story short, both OSs thought that they were installed on C: and everything was fine, each saw the other partition as D:. So all the programs and everything all pointed to C:, because the C: designation was relative at that point.

Now I just got a larger SSD and I wanted to image both the OSs onto the new SSD (in separate partitions). Seeing as the new SSD had no MBR or BCD, once both the OSs were on it, I had to build a BCD. When bootrec.exe was scanning the OSs it found 2 Win7 installations (one from the HDD and one from the SSD). I asked it to create pointers to both and figured that I would use something else to create a pointer to the XP installation later. What happened is that it considered the HDD Win7 to be C: and the SSD Win7 to be D:. The OS would boot from the SSD but kept looking to C: to run programs, because the image that it came from used to think that it was C: and all the pointers for executables and etc were to ...

A:Drive Letter assignment for OS, want multiple OSs to think they are C:

The conventional use of Windows and other OSes dictated that you can have only one drive letter per partition [each HDD needs at least one partition], i.e. can't have two C: drivers. Check your BIOS, the 0 or 1 drive is usually the boot drive [first drive scanned for bootable files] and gets the letter C:. But the newer computers may have changed that.

I'd think it possible to install two versions of Windows on different partitions on the HDD and from all I've seen and read it has been best to install the oldest OS first and newest OS last. I haven't tried installing Win7 after Win8 yet.

Well, I was lucky. The HD that failed this morning, works if I lay it on its side. So I was able to ghost everything over to the new drive. I ghosted the boot partition c: to r:

I'm using Windows 2000, SP4. The new boot drive is SATA. The old, failing boot drive is IDE.

I worked through a number of problems, but I'm left with this:

When the system boots into the new drive R:, it still wants the boot partition c: for something. If I boot with the IDE disconnected, it'll boot to the login screen, and allow me to log in, but after a few minutes of a blank screen & cursor, it drops back to the login.

I have PartitionMagic 7.0, and used DriveMapper to change all references to C: to R:, but that didn't do it. How do I cut my system's dependence on the failing drive, before it fails altogether? Will this work?

What I use my computer for mostly is downloading music, and then burning CDs and archiving the original files on DVDs. Recently, due to (what I eventually came to understand was) a cyclicac redundancy error, Nero and my burner kind of seized up on me. Through various searches of places like this, I was led into uninstalling and re-installing Nero (with no problems) and then doing the same for my burner.

The burner is an NEC ND-3520A, I'm using Windows XP.

After reinstalling the burner using the Windows Installation "Wizard", I realized that I was left with an "empty" (unassigned?) D: drive, which was where my burner used to be, and now the burner had become the E: drive. Didn't think much of it at first, because CDs burned fine, as did DVDs. Then I got to the next step in my archiving process, which is verifying the .shn and .flac music files to make sure the burn was good. And it just took FOREVER, probably about 5x the normal speed.

Granted, I'm only assuming this problem is related to the drive letters, because that's the only change I was able to notice. I did try the Control Panel>Administrative Tools> Computer Management > Disk Management thing, but all that's listed there are my 2 hard drives and not my burner. The burner is listed under Removable Storage > Libraries, where there is no option for changing the drive letter. (If that's even the problem to begin with).

I see can change drive letter H: to E: and save the change , am I right or wrong ?
or any other way
any help appreciated , thanks .

Have you tried Disk Management, right click the partition you want to hide, select Change Drive Letter and Path, click Remove?

Been reading as much as I can and know there are limitations to what I'm asking. But when I dual booted all drive designations show up normally in Win 7.

In XP it shows the OS on drive I: Drive letters E thru H are taken by USB ports. This will cause a lot of confusion for the person that will actually use it. Is there a way during set-up that I can disable the USB ports so XP will show up on Drive letter E?

I'm willing to do a fresh install again. Have only loaded the OS for Win 7 and XP so far.

I installed Win 7 first then XP. Used Easy BCD to repair boot file. If installing XP first is better, I'm willing to do that.

Any help would be greatly appreciated and thanks just for reading

A:Win 7/XP dual boot drive letter question

Robb -

I think your idea to reinstall with XP being installed first this time will solve all of these issues.

Win7 when it is installed last will correctly configure the drive you are booted into to always be C and auto-install the Dual Boot Menu.

This is so much easier and more convenient that it's worth the trouble to reinstall.

I have an SSD drive with 2 partitions on it. 1st partition has Win 7 on it as drive letter C. 2nd Partition has Win 8 on it as Drive letter W. At 1 point in time if I booted to Win 8 the drive letter would dynamically change from drive letter W to Drive letter C and make Win 7 drive letter W. The revers was true if I booted to Win 7. Something has changed somewhere, where this dynamic drive letter changing is no longer working. When I boot to Win 8 the drive letter remains to be drive letter W & Win 7 is still drive C. This is causing problems when I'm booted to Win 8 with regard to installing & using apps while in Win 8 since the C drive is really the Win 7 system drive.

How can I fix this to get back the dynamic flip flopping of drive C? I confess to being somewhat ignorant when dealing with this particular area of things.

Any help would be much appreciated.

I'm using multiple hard drives to install both fedora and w7. I've followed this online tutorial exactly:
Dual-booting Fedora 14 and Windows 7 on a computer with 2 hard drives

The problem I seem to be facing is on the "Add a new Entry Step". His secondary OS partition has a drive letter assigned to it and I do not. I've gone into computer management and have tried to assign a drive letter to either of my secondary OS's hard drive partitions and it will not let me.

Am I missing something? All I need is the boot loader to link to my second hard drive when the second option (OS) is chosen.

A:Dual boot w7 and linux drive letter problem.

Best when using separate HD's to boot via the BIOS, to keep HD's independent and avoid GRUB corruption of Win7.

In your case with two HD's I'd unplug the Win7 Dual Booted HD to install Fedora, set first to boot in BIOS.

After install, plug back in Win7 HD, set preferred HD as first to boot in BIOS, boot other OS HD using one-time BIOS Boot Menu key.

I would like to know how to have the same letter in the two partitions which I dual boot.For example,when I boot into Windows 8,the boot partition's letter is C:,but Windows 7's partition letter is G:.I shrank the C: partition,formatted the new one and didn't assign any letter.In a previous time,I could have Windows 7 partition as C: when I booted into it and the 8 one had the letter E:.The installation DVD showed the non-assigned-a-letter partition as G:.What shall I do?

A:How to change the drive letter in a dual boot computer

If Windows 7 isn't C when it is booted then this is because it was installed from another OS and not correctly booted to install. This blocked the C letter from being available to assign to it.

Windows 7 would not be expected to be C when it is not the booted OS, as the booted OS should always be the only one assigned C.

I searched for my specific issue but haven't been able to find it.

I've a dual-boot setup with XP Home SP3 and Win7 Pro 32bit on one hard drive, data on the others, and two DVD writers.

After Win7 was installed, the XP partition received the letter D:

This screwed up my optical drive letter assignments.

Shown in the pic is Disk Management in Win7. (In XP, the Win7 partition shows up as I:, which causes no problems)

When I went to change the XP partition letter to X:, so that I could reassign my opticals to the standard D: and E: letters, I got the message shown in the box.

My question is, is it possible to reassign the XP partition's letter, so that I can get D: and E: back as optical drive letter assignements? Will reassigning the XP partition a letter other than D: screw up booting Win7?

A:Dual boot Win7 & XP, XP partition drive letter reassignment?

I certainly wouldn't advocate trying to change system drive letters.

I think, quite honestly, your best solution is to allocate new drive letters to your optical drives.

I would suggest K and L so that the two optical drives are unaffected by whichever system you boot into.

Hi, I'm new here, but I heard these might be good forums in which to ask, so I hope some expert will see something I'm missing.

I originally was running Windows Vista x64 as my sole operating system. When the Windows 7 beta came out, I created a new partition and began dual-booting. I have been using that beta as my primary OS for several months, I think, keeping the other drive and the dual boot capability. I can't remember for sure, since I have blank DVDs but can't find a Windows 7 beta DVD, but I -think- that my method of installing the Windows 7 beta was as follows:

1. Mount Windows 7 beta ISO with Daemon Tools Lite
2. Run the setup program from it (or maybe I extracted the ISO to a directory and then ran the setup)
3. Install Windows 7 to the D: partition that I had created, while running Vista
4. The beta automatically configured dual boot. If I booted Vista, Vista viewed "itself" as drive C, and Windows 7 as something like drive D. If I booted Windows 7, it viewed "itself" as drive C, and Windows Vista as drive E. This was perfect.

I've been putting off installing the RC due to being busy/lazy, but I finally tried doing it over the weekend. I have tried four times, and all four have met with the same fate. The dual-boot configuration that gets generated looks right. Windows Vista boots viewing "itself" as drive C, and 7 as drive D. Windows 7, however, views "itself" as drive D, and Windows Vista as drive C.

A:Vista / 7100 RC dual boot drive letter problem

I had the same thing happen to me once and I think it was because after I created a new partition I assigned a drive letter and that was then used when I booted into Windows 7, so the solution would be not to assign a drive letter when you create the partition and just let the Windows assign the letter it wants during the installation.

Hopefully someone else can confirm this for you, good luck.

I have a dual-boot xp/vista setup using microsoft's bootloader. The booting os selected drive always gets assigned as drive C:. I use Acronis' True Image to make hard drive image backup's of my 2 os partitions and mbr and have successfully used it to restore the hdd. That was until I used the latest version of TI the first time. It created the image ok and I could explore it successfully using TI. However, I recently had to restore my hdd and now the chosen boot os drive gets assigned drive letter D: instead of C:. This is true for both os'es. Both os'es create a temp user settings area and I can only run some default windows apps like My Computer. Acronis has been no help so far. Last time I had a boot problem fixmbr or the vista restore facility would only fix 1 of the 2 os'es and I ended up completely re-installing vista again to fix it.

Can anybody give me a better solution this time around? Thanks.

Hi, I hope someone out there can give me some advice on what I need to do.

I've just bought a new computer for making music on, this is an upgrade from my old XP system. The computer comes with (when it arrives) windows Vista, I have also bought another copy of XP.

What I would like to do is create a dual boot system with XP and Vista but after looking into this I came across a problem. I have a second hard drive with all my music files on which is an E: drive. After reading an installation guide for a dual boot system I read that the second OS installation automatically installs the OS as E:.

My problem is that my 200GB E drive is full with music project files that need to run from the E drive because they contain audio files, changing the drive letter would cause each project to be unable to locate it's audio files.

What I need to know is if there is a way I can install the two OSs on one hard drive and keep my other hard drive as E:.

I've heard about virtual PC but I'm not sure if using this it would be possible doing it this way either...

If anyone's got any advice it'd help me out loads

Hello all...

My goal is to run a Win7/Win7 dual boot system with one installation for day to day operations (MAIN) and then second installation strictly for gaming (GAMER).

I have successfully installed Win7 twice. During clean install i created 30GB partition (C: ) and put MAIN there. No problems. I loaded that up and from within Disk Management created a second partition on the same physical drive and named it (D: ).

I booted from the Win7 install DVD and then installed GAMER to the (D: ) partition. No problems. I am able to boot into each installation (MAIN and GAMER) from the boot manager without any troubles.

When I boot into the MAIN installation, the system path/partition is (C: ) and the os files for the second installation, GAMER, can be seen on (D: ) just fine.

However, when i boot into the GAMER installation, its system path is also (C: ) and the partition for MAIN somehow got renamed to (G: )

I would like it so that when I boot into MAIN (which was installed to C: ), that partition stays named (C: ) and when i boot into GAMER (which was installed to D: ), that partition stays named (D: ). Eventhough both installations see themselves as (C: ) when i boot into them, it does not seem to cause any problems.

So how should I do my second Win7 installation to a partition named (D: ) and force it to keep that name when i boot into it?

I have a HP Pavilion m7750n. It came with Vista, but I formatted and put on XP.

I was having a lot of problems a few years after switching due to viruses, and what not, so I had a friend attach my HD to his computer to completely format it. We put it back into my comp, put XP back on it, and installed drivers. A couple months later, I went to HP to get a driver for the media part of the comp. When I tried to install it, it said that I had to free up memory on my C: Drive.

When we put the drive back into my comp and reinstalled everything, my HD set up a H: not C:

I went looking on how to change my drive letter back to C: and followed these instructions: http://support.microsoft.com/kb/223188

I followed them exactly. When I rebooted, it came up to a screen that looks like the user choice screen, with no users. I can not click anything, and my keyboard only beeps at me.

I cannot boot into safe mode, and I tried clearing the boot proticals by moving the jumper.

Any ideas on how to correct with out reformatting again?

A:Changed Boot Drive Letter, Now will not boot past MS Windows XP screen

Read other 11 answers

Ok, so last night I stupidly changed the drive letter on my Windows XP partition from F:\ to C:\ with Partition Magic 8.0 in attempt to get a program to install needed for my music class(the program automatically installs to C:\ w/o prompting for a install location). I didn't realize my Window's install referenced the the drive name, not just the partition itself.

So now when windows try to boot, it gets the point where it logs into the administrator account, but it will not log in fully, then it will log out, then tries to log in, then logs out, logs in, logs out, etc and never breaks out of the loop. I tried to change the drive letter back but the boot disc of Partition Magic would not allow me to do so. I ended up having to reinstall a second instance of Windows temporarilly.

Does anyone know of a way to modify the registry on the previous install to boot under the drive letter C:\ while under this temporary install of windows? I really dont want to go thru the trouble of reinstalling all my apps/drivers/etc on this new install if I can get the original install of windows to boot.

Hi support/helpers

My laptop was booting, but got locked up at one point, well it was not doing anything and seemed to be stuck. Maybe I should have left it a little longer to see if it sorted itself out but I didn't. I held the on/off button down to do a "hard restart". In hind site a dumb thing to do but you can only stare at screen for so long and move a mouse backward and forward with nothing else happening.

The laptop will now not boot, it goes into repair mode but cannot solve anything. It gives me an option to go to the C: prompt in repair mode, which I can do.

The Problem:
my original C: drive is now my E: drive, my D: drive is now my C: drive, my E: drive is now my D: drive.
Everything seems to be ok folders and files etc. just the drive letters messed up.

I guess I corrupted something. Is there a way of getting the drive letters corrected so I can boot into windows?

I cannot press F8 to get to safe mode etc.
In the bios my hard drive is seen and is the first boot drive
My hard drive does have 3 partitions, originally c,d, e. C was where windows 7 was installed too.
I see a recovery folder but dated 2009 and to scared to use it as so old, not that I know how to use it.

Any help would be appreciated, hoping for a simple free utility I can download to sort it all out.

I have my OS on a Vertext SSD C drive and all my files (mainly photos) were on a 1TB portable USB drive.

To make Lightroom run faster when editing huge numbers of photos I decided to upgrade the 1TB USB to a 960 GB SSD. This went fine until I tried to change the drive letter after completing the copy. My old USB drive was V drive and I wanted my new SSD to now be V drive.

I changed the USB to be W and then the new SSD was changed from D to V. This would ensure my Lightroom catalog plays nicely with all the file references, presets etc.

But when I do this windows won't boot. It just hangs after 'Loading Operating System'. No matter what I do, when the SSD is V drive windows won't boot and if I force it to be any other available letter it boots fine. I even deleted the volume in disk mgmt then used the new partition wizard to create a new one assigning letter V in the process. Still would not boot.

Changing the Lightroom catalog to reference a different drive is a real nightmare and very time consuming so I don't want to give up just yet. Does anyone know how to trick windows into letting me use letter V for this volume?

A:Windows won't boot if SSD drive letter changed

Have a look in HKLM\SYSTEM\mounted devices and see if V is listed there, if so, delete it.

After a computer crash, burn & recovery, the SW I now download installs in my backup drive D: instead of my operating system C:. In some cases, I have no control over where it is to be installed. I suspect the problem glares at me when I look in Admin tools, Computer management, Disk management and see: Disk 0, C: System and Disk 1, D: Boot. These may be reversed because C: is my boot disk with Win XP on it & D: is only used for backup. Trying to change these assignments is scary to me & I don't know what "system" means.

Also, when rebooting, I go to a logon screen that tells me to choose from one of two operating systems, both of which are the same (XP). Please advise me how to fix these problems.


A:Drive assignment & boot screen problems

Apparently,when you restored,you installed to the partition on D:.
Could have been a simple matter of not reading the screens,
i've done it before.
This can also happen if you are running anIDE drive as primary master and a
SATA drive on channel 1.
You tell it to install to the SATA and it still loads system files on the IDE
In any case,it looks like you ended up with a dual install.
If you don't have anything important on there,you can reinstall with the D:
drive disconected,the reconnect D: and format it after.
Should correct the problem.
