I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link (This link will automatically start a download of Reimage that you can save to your computer.)

A: changing one drive letter all 3 partitions change to that drive letter

First thing you're going to do is fill in the specs of the desktop whose snips you are showing us.

Then you're going to do the same with the second pc opening a second post with snips. Give it a different title like "Second pc with drive letters the same". Don't forget the snips.

You should not have dynamic disks in either machine. What did you do to accomplish this?

There exists a bevy of spectacular experts on this site that will be happy to help you. But give us ALL the info please.

A:Will changing drive letter of HDD on one computer cause it to change on another?

A drive letter assigned on one computer has no effect on a different computer. However, if you modified the system drive letter (C in Windows while it was booted up, you'll have all kinds of problems, and I doubt the computer will even boot up again.

I lost my Event Viewer, and had to do a repair installation to fix it. Unfortunately, during the repair install, Windows decided to rename my second HD as the D: drive... it was K: before that. Now I cannot access any of my docs, pictures, music, or videos through the normal means... they don't show up in libraries or explorer, and apps like Restorator and Sure Thing (CD labeler) cannot find them. I think that means the paths are broken..?

It won't allow me to rename the HD back into K: (it's not listed as available). I can access the data by clicking Computer > D, and I can see the data is there, but its unusable as of now. Any ideas?

A:Can't change hard drive letter to needed letter

Hello Stevie,

To be safe, you should create a restore point before doing this in case you make a mistake and need to use it to do a system restore.

1. If the K letter is not being used by another internal drive, then you can open regedit and navigate to:HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices
2. In the left pane, Take ownership (step 2 in Option Two of METHOD TWO) of the registry key MountedDevices and "Allow" yourself "Full Control" of it as well.

3. In the right pane of MountedDevices, right click on \DosDevices\K: and click on Delete and OK.

4. Restart the computer to apply. You should now be able to change the second hard drive letter to K.

Hope this helps,

A:Can't add drive letter to partition, have 7 primary partitions

Shot in the dark:

As you said, you can only have 4 Primary Partitions. I suspect that Windows knows this and is therefore saying "Well that can't be right" and assuming its made a mistake and won't let you assign drive letters.

If you get it down to 4 partitions again, it will probably let you assign letters.

A:External Hard Drive - Drive Letter changed - unable to change back


Welcome aboard.

Try this:

Download V 0.8.1 from

Drive Tools for Windows

Unzip to a folder. In it you will have two folders Win32 and x64, each containing DriveCleanup.exe for Windows 32bit and 64 bit respectively.

Now unplug all the USB devices from your PC (except of course the Keyboard and mouse), right click on the appropriate DriveCleanup.exe for your system and run it as an administrator.

This will remove all non-present drives from the registry.

Reboot and then plug-in your external drive.

The drive will be installed and hopefully you should be able to assign any free drive letter to it.

Please report whether it resolved your problem.

My External Hard Drive (My Book) was always Drive letter F.

I went to sleep and woke up to find Windows 7 Pro had updated and rebooted and I was welcomed by my login screen.

Consequently now my My Book external HDD now reads as Drive letter G.

I went into Administrative Tools > Computer Management > Disk Management

Drive letter F is not available.

F is assigned to a drive that does not exist and never has. I am confused. I only have one CD drive and it says now that I have 2 even though the one addressed as F doesn't have any information. If I click on F it says "Insert Disk"

The short answer: You can't. The letter is assigned when XP is installed.

In order to be sure that the drive is C:, it's best to install XP with other drives disconnected to a newly partitioned and formatted drive.

Hi, firstly, i apologize if this has been discussed before.

I followed the guide posted here to dual boot XP & 7. All's working fine now. I can boot into both the OS without any problems.

However, i've noticed that which ever OS i boot into, shows itself as installed on the C: drive. When in XP, 7 shows up on E: drive & when in 7, XP shows up on D: drive. I wanna change this. When i installed 7, i chose the D: drive &that's how i'd like it to remain.

So yeah, how do i go about changing the drive letter of 7 from C: to D:, so that it remains that way no matter which OS i boot into. Would it be safe to do this from Disk management in 7?

Note: Both the OS are installed on the same HDD.

I once again apologize if this has been asked before.


A:Changing 7 drive letter.

When custom installing a second copy of the same version, same edition using the same installation disk the second copy of Windows having started up the installer while in Windows will shift the second copy to other then C. When booting into a dual with two different versions or even two separate editions of the same version the normal sight is seeing C while in one and the other install as a different drive letter since C is in use at the time.

The best advice often seen with any dual boot and the optical drive being D would be giving the second Windows E, F, G, etc. if no other drive is present and doing the same while booted in the other to the first now second seen there in the DM.

For changing it from C to something else that would be the opposite of wanting to see the registry edit for correcting a goof of Windows getting the wrong letter like D assigned rather then the default C. How to restore the system/boot drive letter in Windows

Note that was directed at 2000, XP, and Server 2003 where this problem had been more apparent. Another guide covers what I was mentioning about how to Manage your drive letters in a dual-boot configuration

While the guide is older there for an XP/Vista dual boot the principles are the same as far as having the second OS always seeing the same drive while the Windows you are in at the moment is C.

So, dumb problem, but forgive me for being an idiot..

I use an external hard drive to store my music collection. Recently, for no apparent reason, Windows re-assigned the drive letter signification of my external hard drive from "F:/" to "G:/". Now all the software I use that references the files on the hard drive is throwing errors saying it can't find the file, and my music player can't find any of the songs in the library.

I could manually change all the addresses in the software I use and re-load my music library but, um, that would suck.

A:Changing Drive Letter

Generally you should not change the drive letter of the system disk, since many windows files and setups rely on it staying how it was on install.

In general terms, it shouldn't matter what letter it is. The only exception is some old programs have C: hard coded in to them, rather than finding the real system disk, but this isn't usually an issue.

However, if I understand your post correctly, your disk was C:, but has changed to X:. I think this can indeed cause problems. You could have a look at but read the warnings very carefully and follow the advice, definitely regarding backing up.

You could also look at , which the first article links to.

Any imaging program should be able to do it. Macrium Reflect seems to be a popular one, and it's free. There are guides on how to use it in the Tutorials section here.

That being said, with some planning ahead, a clean install can take under 2 hours (complete with apps), and I have always preferred that method to ensure my SSD was set up and aligned properly. When Windows 7's installer detects an SSD on an AHCI controller, the OS configures itself properly for the drive.

I installed a new hard drive and installed winxp pro. Not realizing it at the time, it was installing on drive F. Now of course the windows drive is not c. as it should be but f instead. Although it works fine, it is very annoying to see f:\windows. Is there any way to change this without re-installing windows?

I know how it happened. The new drive that was installed was on IDE 1 as the Primary Master. I was under the impression that if I simply swapped the drive to IDE 0 it would correct the problem but I am obviously mistaken. I thought maybe I could use PQ Magic to remap the drives. Not sure though.

Really could use some advice here. I can't stand it anymore!

I don't understand how, but when I installed XP MCE, it was with all other drives disconnected. However, when I went to Disk Management, it's partition is labeled G:, while W7 is labeled L: when running MCE. I want to change G: to the usual C:. but Disk Management won't permit that, and when I tried something similar with Acronis Disk Director some time back, the OS would no longer boot, so I'm not anxious for a repeat performance.

The question is, how to relabel the partition safely?

A:Changing OS Partition Drive Letter

I wouldn't and don't think you can change it, not without re-installing. As you have seen Windows won't let you change the drive letter of the partition windows is installed too. The main reason is that doing that would break a lot of programs etc. They would be looking for the old drive letter not the new one. Do you have a flash card reader installed? If yes that would be my guess as to why the drive letter got to be so high. I've seen that happen in XP if the hard drive wasn't formatted. It doesn't get a drive letter until after its formated. The other formatted drives would get C:, D:, etc. I didn't think windows 7 did that anymore but I could be wrong. Like a lot of people, I've only been using it for a short while. Now that the drive is formated it should get the first drive letter C: so a re-install should fix it. It just depends on how much that bothers you as to whether you want to do it over again.

I was doing a new installation of XP home on a new hard drive, XP formatted the drive as F:\ and installed the boot sector there because a thumb drive was in the usb port (which it recognized as C:\). I wasn't paying that close of attention and I didn't realize XP would see that thumb drive as C:\. My question: is there any way to change the boot letter back to C: without reformatting the hard drive?

So i wanted some more space in to my C drive and I downloaded Partition Wizard. It got the job done and changed 10gb from my D drive into my C drive. After the restart i had to do, the problems started. My computer now showed my D drive as a cd driver or something and when i tried to open Steam it told me to put in the DVD or something..
I didnt know what to do so i messed around with the Windows disk management thing and changed the drives (D) letter to F just to see what would happen.. my computer froze and i got a blue screen:

And when i restart the computer i get this one first:

I cant do the check that the black screen is suggesting because it cuts to the blue screen in ~1 second.

I cant get past the blue screen, it does this and then it restarts over and over..

Hi Souzr.

Do you have access to another computer right now? If so, download Partition wizard Bootable CD (the last one in the link). Burn it in a blank CD or in a USB flash stick.

Boot into Partition Wizards GUI following this instructions. When you are on the last screen, take a camera snap of the screen and upload the snap here.
Screenshots and Files - Upload and Post in Seven Forums

We need to see the partitions and parameters.

Also, better you perform a bootable HDD scan, as the second image says. Try Seatools for DOS. Let us know the results.

I recently just reformatted and added in another HDD. The old setup was a WD 500GB, Hitachi 1TB, and Seagate 1TB, with a Asus DVD drive all installed through Sata connectors.
When I formatted the F drive, being the Hitachi 1TB, it took the OS just fine and I was able to install all my programs and games. Though when I removed the WD 500GB and installed a newer WD 2TB there seems to be a huge problem.
My drive lettering has automatically changed, forcing the F drive to a G drive, the D drive, which was the DVD drive, has been changed to F.
I've gone through dos prompts from the only known source I can get to, a win 7 install disk in recovery options. Yet every time I change the lettering through diskpart in dos, it never sticks.
Can anyone help me in this terrible predicament.

Ok, the computer i'm working on currently went through a lot of stuff, basically it stopped "seeing" both hard drives... it's a dell, so I look at the array, and it sees them there, so I decide to format both of the drives (the user had backed up all their information thankfully) however now it says that C: is a removable media and F: is my boot, which would be all well and dandy, but I'm trying to download drivers from a website, and it won't let me choose where to download to, and it tries to download to c, which won't work. So is there a way I can change the boot drive to C? Maybe by switching the ide cables possibly?

A:Changing Boot Drive Letter

Actually since the system has made drive F: your boot drive and C: a removable media the only real way is to re-format the drives and re-install Windows again but this time you have to read the screens as to where the installation is formatting and where it is putting things. Basically you read every screen and you will find it.

Hi all,

I'm running Windows XP SP3.
My external hard disk drive letter keeps changing every time i plug it out and back in again.
For example, if have assigned it to H:\, after plugging it out and plugging it back in again it changes to I:\.
It happens every single time and there is no way to change it back to H:\ as it disappears from the "Change Drive Letter" drop down list in "Control Panel>Administrative Tools>Computer Management>Disk Management".
The only way to make the letter come back into the drop down list is to restart my computer.

Please help, i've tried almost everything except reformatting my computer which is something i dont want to do.

Now when I plug it, the error message is on Win7 is "You need to format the disk in drive"
The error on Win XP is D:\ is not accessible

which is quite weird.

The drive is not used much, it never had surface problems, etc.

Look in your registry under HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices. That's where drive letter assignments are stored. Find \DosDevices\Y: on the left side and note the data value on the right. The next time it happens, check the same registry location but find \DosDevices\J: and see if the data value is the same as before. Also see if there's still an entry for \DosDevices\Y:.

I recently installed a new SSD, and put windows 7 ultimate x64 on it. this installation occurred while another instance of windows was on a separate HDD that was still installed in the computer. because of the existing install, my primary drive letter was set to D:, i have since scrubbed the old HHD and the windows installation on it. When i attempted to change my primary system drive letter from D: to C:, i got the error "The Parameter is Incorrect". Does anyone know of a way to force windows to change this?

I attempted this change through windows disk management.

*I have already backed up all information, and took a snapshot of the drive in case of catastrophic failure.

Thank you in advance for any assistance given.

A:Error while changing primary drive letter

You can't change the letter of the system drive, IE the drive Windows is installed on.

Your first mistake was leaving the other drive connected when you install the OS on the SSD.

If I were you I would start over with a Clean/Fresh install on the SSD. That is after you backup any data that may be on that drive and also have all other drives disconnected before you start the install on the SSD.

Hello amoretam,

Check using OPTION TWO in the tutorial below to delete the /DosDevices\(drive letter) entries for these drive letters and any others that you no longer use, and then reassigning the drive letters you wanted for these drives may have them stick afterwards.

I would recommend assigning them something like X and Y so they wouldn't be so easily used by anything else.

Hello Everyone,

I am trying to get my external hard drives setup from a freshly rebooted installed computer. I recently placed an external hard drive with all my back up files on my computer, but this drive is not going to be my main drive. I have two others I will be using as a main hdd and a backup drive that are brand new.

So, the question is, if I were to use a utility like the Windows 8.1 disk management feature to either delete the drive letter or even change it to another one, will that mess up the external hard drive or even lose data? Because until I transfer my files to my backup disk I am afraid of losing my only copy of my files.

Thank you all for your help.

A:Will deleting or changing a drive letter mess up a hdd.

Drive mapping will not allow it, so it will render one drive missing from the drive list, or simply refuse to read it right. That is why you do not mess with drive letter assignments unless you know all of the ones that reside on the current system set up. when adding an external drive also.

Now you have to go into windows, click on start, then in the search box type disk man.
Click on create or format partitions.

Let the window open and look at a drive with the letter you assigned to right click on it.

Change the drive letter and push it to for example J or K.
Once done restart the pc, and all drives should show and be accessed without trouble or being asked to format them.

You may have to disconnect the external drive first from the computer first to get windowsto load, but once done plug the external drive in.
It should show up as a device in disk manager, so if it does change the drive letter that way to J or K. then restart the system and all should show and work.
It is asking you to format it to assign a new drive letter since two assignments of drive letter D: exist

First look to see if there is another \DOS\Devices\C:, if there is, change that letter to an unused letter before

its win 7 installation with one hd [no extra partitions] and one usb drive

some problems are:

if i try to change system drive letter i get parameter is incorrect

also [recently] system drive was not set as active, it is now corrected

cant get permission [after reading several articles on the subject] to do windows updates or install MS Word and a few others but not all installations are blocked

cant install iTunes [no reason given]

cant get Windows Tweaks all in one repair tool to effect repairs [runs all night]


A:cant change drive letter

Please post a full clear shot of Disk Management, and we`ll go from there.

FYI, the windows install drive or partition`s letter, or even another drive with programs installed on it should never have it`s letter changed, only a data drive or partition`s letter can safely be changed.

I'm trying to change the letter of the drive, and I followed these official instructions:

BUT, "Assign the following drive letter:" is unselectable/uncheckable. How can I change the drive letter if I can't do this? Thanks.


I need to change it because Flash won't install because my drive isn't C. This is according to the Adobe website.

A:Can't change the drive's letter

You can't change the drive letter of a system partition. More importantly you DON'T want to change it. Here's why: everything, all your settings in the registry (like where it says to load drivers, programs, and everything) refers to drive J: ATM. If you were somehow successful in changing the drive letter, you'd probably get a BSOD at startup because it's failing to find critical files to load.
The only solution (and it's really more trouble than the problem) is to reinstall the OS from scratch on a C: drive (first primary partition on first internal hard drive).

yo. when i baught my computer it came with a card reader. the slots in the card reader were for some reason assigned the drive letters c: e: f: and g:. This resulted in the computer assigning my hard drive the letter h:. This is very annoying because when i anstall programs etc. i have to change the default path of installation. I have tried to use computer management > disk management, but when i try to change the drive letter it states:"Windows cannot modify the drive letter of your system volume or boot volume"screenshot of my predicamentAll i want is to change the drive letter from h: to c:I hope this doesnt turn out that i have to remove the card reader manually then install it again after i have assigned my hard drive the letter c:Please assist...

A:Cannot Change Drive Letter

I hope this doesnt turn out that i have to remove the card reader manually then install it again after i have assigned my hard drive the letter c:Bingo!!.... That's your best bet.It's only going to take 5 minutes of your time.[Added Info]While you're at it, check the pins on your hard drives and make sure the one you want to have as drive C is set as the master.

I am trying to take a slightly used 250g hard drive from an XP computer and copy the contents from my 80G Win 7 to replace it. I assume I need to change the drive letter on the 250 so when I slave it into the Win 7 machine it will recognize it.
The problem is the old XP machine will not let me changer the drive letter. I get the message "windows cannot modify the drive letter of your system or boot volume".
Any suggestions? Thanks.

Hi people,

I need to install win3.1 to run an old application. I have tried using DosBox and running 3.1 within that but it is waaay too slow I need w3.1 to be installed clean on it's own drive C: then install the old app for a dual boot system with XP.

I currently have XP-home installed on C:

Is there any way I can change that XP drive assignment to D: and create a new partition to use as C: for the win3.1 install? Win3.1 will only install to a drive C: as will the old app.

I checked the following link but am not sure that it will do what I want to effectively move XP to drive D:

I installed a CD burner and had to do some moving around with the IDE cables. The burner took a letter assigned to another drive so I went into the device manager and changed it. That was ok and that fixed that. I lost the use of my zip drive somehow (?) so I went in and fixed that, but now my zip drive is the letter B instead of E and I want it to be E. I can't change it in the device manager because that option is shaded and I can't change it. I was told that I needed to go into DOS to change the letter, but I am not familiar with DOS. Can anyone help me with this? I know it's not a big deal and I can still use the zip drive with the letter B, but ... Thanks, Liz

I have a problem, that sometimes, after installing Win XP (SP-1), I find the OS installed to another drive then C:.

The machines I've had this problem with, had one (new, empty) harddisk, and a CD-ROM burner installed. The harddisk was always more then 100GB in size.
Usualy the CD-burner would get E: and the harddisk would get F:
I haven't been able to find out why C: and D: is not available from boot.

But is there an easy way to change the drive-letter, once it's been assigned?

I'm looking forward for your replies.

I deleted my existing OS then created two new partitions on the same drive. Then I installed Vista on one partition and that partition was properly named "c" as ususal. Then I started Win7 setup.exe from a different hard drive and let Win7 install itself into its own partition. When I got to "My Computer" the Win7 partition was labelled as "I" instead of the expected "C" which had never happend before when I did the same thing.

Does anyone know a save way to label the Win 7 drive as "C" while in Win7?

I have Windows 7 installed on an SSD 128 GB drive but I'm upgrading the drive to an SSD 256 GB. But at the same time I want to keep the newly installed drive letter as C: like the old one so I can use "C: only" software.

My present hard drives are:

Primary Windows 7 128GB SSD - labeled C:
ASUS DVD Optical - labeled D:
WD 1TB Internal Storage - labeled E:
Seagate 800GB External Storage - labeled F:

When I tried to reboot with the new drive plugged in, Windows 7 recognized the system image from my internal storage E: drive but in the System Recovery Options menu, the storage's letter suddenly changed to C:...

How do I keep the NEW 256GB installed drive as C:? Is it possible to change the primary drive letter in Windows 7 Disk Management back to C: after a primary SSD drive switch and system image recovery?

A:Want to change Primary SSD drive but keep Drive letter at C:

Robinsongs, welcome to the windows 7 forum.

If you install the new ssd in your d slot after restoring your image to the SSD, your bios will normally allow you to
select the boot drive. which you can select as the new SSD.

I would remove the old C drive and place the new ssd in the old C slot. Should be ok.

This way when you boot your machine the bios should automatically boot from your new ssd.
If you have restored your old c image to the new ssd properly.

Bios normally allows you to select boot devices.

Hi, I have an Asus n61 notebook & a 1tb WD external drive connected via esata. I want my notebook to recognize the drive as G, for program pathway reasons, but as it needs to be connected before power up my system sees it as F. When I try to 'change drive letter' in Disk Management it simply says 'the parameter is incorrect'. I have never had problems assigning drive letters in XP. What is the secret in W7?

The drive letter of my boot/active Win7 partition should be C:, but in my case it isn't; the boot/active partition drive letter is F.

I've tried to move heaven and earth to change the drive letter of the boot partition but nothing works.

So, aren't there any apps, tools or utilities to change the drive letter of my current boot partition?

Thanks in advance,

A:Changing Drive Letter of Boot/Active partition

Nothing that I know of. My original Win 7 installation was "E" drive. I had considered things suggested but finally decided to let it be. It doesn't matter to Windows what the drive letter is, everything works regardless of the drive lettter. I later installed Windows 7 on an SSD drive, with a clean install (and the SSD drive the only drive connected during installation) and now back to the "C" drive.

I have just replaced a SATA hard drive that crashed. I booted with the original XP Pro cd and installed . Somehow, the setup named the hd with letter "I" I want to change it back to C. I don't remember it ever asking me what letter to use. Is there a way to change it without reloading XP? I went to disk management, but it wouldn't let me change it because it is the boot drive.

I use a flash drive to install certain things on multiple computers. What do I put in the shortcut info so that it automaticly will default to whatever drive letter that flash drive has at the moment?

I would have googled but I couldnt figure out how to word it.

A:Simple shortcut question, changing drive letter?

To the best of my knowledge when you plug in your flash drive it will default to the next drive letter that particular system has available.
I know of no way to make the flash drive to install on different system with the same drive letter all the time.

Hang in there we have a lot of members and maybe someone will be able to help.
I will be watching to learn if their is a way to do such things.
