Hi, I'm not sure if the title sounds about right but I have Windows Vista Ultimate with 3 hard disk drives, C, D and E. The D:\ drive is about 55GB and E:\ is 300GB. I'd like to change my E:\ to D:\ and vice versa.

I went to right click on the Computer icon, clicked on "Manage" and went to Storage and then Disk Management...

Here's the screenshot:

I can't seem to rename the D to E as the pagefile is there.. Now, I'm not really an expert on this and if someone could shed some light on how to rename the drive, I'd appreciate it so much!!

Thanks so much in advance!

A:Solved: Help On Renaming Hard Disk Drive Letter

This ones rather easy. Move your page file to the C: drive. (Control Panel, Performance Information and Tools, Advanced Tools, Adjust the appearance and performance of Windows.)

Under Advanced, click on Change.... Click on the C drive and make it System managed size. Click Set. Make sure all the other drives are set to None. After you OK your way out, you may have to reboot.

Now, you can change your drive letters. You can also go back and reset the pagefile. Note, by the way, that changing your drive letters, could cause some programs that look for the drive letters (including anything installed on the drives) to fail.

A:Renaming C Drive Letter

Back in XP days you could install the OS on a partition other than C:. But with Vista and later the OS has to be C:

Is the HD a USB external? The only way I could see to do it without taking the SSD out would be to restore an image of the OS onto the external and boot it as C: then install the work programs. To run the programs you would first have to boot the Laptop from USB instead of the SSD.

Also I am not sure if you can do that without any licensing problems. It may be easier to pick up a used W7 machine with a large HD and just install your programs on it.

Hey TSF, i'm a student, and I recently bought a 500gb External Hard Drive for use with school. I also bought a PS3 and would like to add my music and movies to that. I researched about the PS3, and learnt I needed to convert the hard drive type (not sure how to describe it) to FAT32. I decided to create a partition, so the whole thing wouldnt be converted to FAT32. But after something I did (I've used Swissknife, but it didnt work, maybe thats something to do with it), one of my partitions that was previsously unallocated space turned into a primary partition. However, it wasnt labelled as healthy or as a primary partition (im just presuming it is because of the blue on the Disk Management window), and also with no drive label.

Sorry, here is a screenshot.

Im not bothered if I have to format it, as I dont have any data to lose on the HDD :)

I tried to changed (Right Click My Computer->Manage->Disk Management ) the partition letter for XP (From F->E) while I was logging to Win2003 , I could not.

I have a dual Raid 1 configuration with (2) identical 500GB (C and 1TB (D drives. When connecting my (2) external hard drives, one of which needs to be named (F (I have numerous files, folders, icons and programs linked to it), I see that (E and (F are the only two drive letters unavailable for use - presumably because they have been allocated as the invisible/dynamic? drives for (C and (D, respectively. How do I know which one's RAID Mirror is? And can I just rename that drive so the letter becomes available without interrupting/changing/affecting the RAID configuration?

Anyhow i connected 80 gig up as slave on primary controller and installed xp pro on it for him
After installation i removed the 20 gig and put 80 gig on master on primary,i dont know why i didnt do this at start,but damage was done
I am getting quick message saying invalid bootini but then machine continues to boot with no problems after that
The issue i now have is the system partition is assigned drive letter D instead of C
How can i change os partition to C


A:[SOLVED] Change drive letter on system partition

Remove all drives except the System Drive (previous D:) which is on the Primary Master controller with the jumper pins set to Master, and restart the computer. The System drive will now be C: Now shut down the computer and add the 20 Gb drive on either the Secondary Master controller with the jumper pin set to Master or with the jumper set to Slave as a Slave Drive on the primary chain, on restart it should be the D: drive.

A:[SOLVED] W7 system partition drive letter changed won't boot

Hi, boot to the RE (repair your computer) at the x:\sources prompt type:-

bcdedit (press enter) this will reveal the boot manager and the boot loader that your OS uses to boot. Note down the entries, next type:-

bcdedit | find "osdevice" (press enter) this tells us what drive letter the RE has assigned the OS, not always C:

It will be this drive letter that you will need to use to repair the boot .

Have just installed a new 8.7 Maxtor in a P100. This drive is set as master and partitioned into 5 which assigns drive letters c,d,e,f,g . If I re-install the old 500mb drive unit as a slave ( Quantum Maverick) it assigns itself as drive letter D. I want this drive to show up as drive H . If I go to Device manager, hard drives, double click on generic ide type 47, settings, for this drive the drive letter assignment is there, but I cannot change it. Any ideas please.

A:{SOLVED} Slave drive letter inserts itself within master partition drive letters

I don't think you can change it. Normally the bios will take the primary of the 1st ide drive as c, the primary of the second ide as d, the next partition of the primary ide drive as e, etc.

To find out why the preferred letter is not available. Type disk management in the search bar on the start menu and select "create and format hard disk partitions". Look to see if the letter you want to use is already in use. If it is you will have to change it first.

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:Partition without a drive letter

The little partition was most likely the "System Recovery" partition that came with the already installed software setup when she bought the PC.

Somehow she has clobbered (a techie term ) the main partition that contained her data and Windows installation.

If she has a set of System Restore Disks (CD's), then she may be able to use them to restore the HD to its original the day she bought the PC.

If not, and it were my PC, I would use FDISK to remove everything from the HD, and then recreate a single partition of maximum size on the drive. Next Format it, and then reinstall Windows...going on from there.

I have Windows 7 RC on my Computer. It is on Drive C:

I got this Vista Recovry disk that came with the laptop, and I was going to use it to dual boot Vist with the Windows 7. The Recovery disk will ONLY install onto drive C, there is NO OTHER intallation options.

The Question: If I change the Drive letter of my Windows 7 Drive to Drive D: and then change the Empty partition to C: will my Windows 7 still be bootable? Even if I chagne the boot loader option of Windows 7 to drive D: ?

A:Change Drive letter: Partition containing OS

I have never been able to change an OS to another letter without bricking the OS. The only tutorials for doing so make it clear it is only if the OS letter has slipped.

What I would do is save externally a backup image of Win7 using an imaging software that will allow you to select where to reimage, such as Paragon Backup & Recovery Free Edition - Free Download or Macrium Reflect.

Then go ahead and do the Vista factory restore, shrink Vista partition in Disk Management, reimage Win7 to the shrunken space. Now boot the Win7 DVD Repair console to run Startup Repair up to 3 separate times to rewrite the MBR to Win7 and possibly configure the dual boot. If not, use EasyBCD 2.0 beta in Win7 to add VIsta.

Others may have an easier idea. You'll have the backup image as a path back, so it's worth a try since Win7's drive letter is in most cases relative anyway.

I want to assign a particular drive letter (R) to a partition on a drive for compatibility with another computer system. However when I attempt to change the drive letter using Windows Disk Management, "R" is not shown as a choice. There is no other disk shown in the listing of Volumes with the drive letter "R", and every other unassigned letter is available, so why isn't "R" shown? If indeed R is assigned to something, how can I find out what it is?

A:Can't assign a particular drive letter to a partition

Hello coffent,

You should be able to use OPTION TWO to see if "R" has already been assigned. If so, then you could use step 4 in OPTION TWO to swap the "R" drive letter with the letter the partition is currently using.

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 have a triple boot desktop computer with XP, Vista, and windows 7, and some storage partitions as fat 32 and ntfs types. Each operating system shows the partitions with different drive letters. From booted in the XP it is drive G, Vista is C, 7 is D, and with the 2 optical DVD/CD drives, and the 3 storage partitions, I can change those drive letters some to allow drive E to then become available for the XP system. So is there any way to change my XP from drive G to E, such as booting to the XP recovery console and using the diskpart or map commands, or some registry edit to do this change, thanks.

Many thx for ideas rick

A:SSD partition on c: sys drive. has no letter 'unallocated'

Are you currently using that C as your OS partition, if so, you need that other partition as is..

101mb is roughly the equivalent of 60 photos, your temp internet files can be 10x that amount. and its not not taking up a drive letter.

Do you really want/need that space?

Run into an issue with a hard drive showing 3 partitions, but I can't assign a drive letter to it.

Background: It was running Win 7 Pro 64-bit, but was having occasional issues with blue screening. I've pulled the hard drive from that PC and have it hooked to my own (also Win 7 Pro 64) via USB external HD enclosure to run scan disks. The first two partitions I'm accessing fine, but the third one won't give me any options, no matter what I try. Any insight would be great.

EDIT: And sorry, right under where the submenu appears that says "Help", it says "Healthy (Recovery Partition)".

A:Unable to assign drive letter to HD partition?

Hi FuryoftheStars,

First let me tell you how to make a full screen Windows Disk Management screenshot.

Before you take the screenshot, go to the top menu bar and click on the "Show/Hide Console Tree" and "Show/Hide Action Pane" to hide those. Then we can clearly see all the columns in the top listing of the drives. Sometimes that information is necessary.

A sample screenshot with no information obscured/truncated:

Now a straight answer to your query:

The OEM Recovery partition in this case (and in most other cases too) is deliberately of a different Partition Type so that users cannot access it with Windows, meddle with it and spoil the broth. You may change the partition type to the normal type accessible to Windows and then assign a drive letter.( If you want to do it, do it at your own risk .)

If information on it is already available, I do not want to rewrite it . Please see Techno Wizard's last post dated 21 Oct 2013 here Assigning a letter to OEM Partition ( Take only what he says about recovery partition. The hibernation partition is not applicable here.)

(Now on my part ) You can also change the partition type using MiniTools Partition Wizard.( Changing it with diskpart by normal users is a little bit tedious and requires care)

EDIT: You can ascertain the current partition type from the "Properties" page in the first right click menu ( the last in that menu)

Having said all this, whatever problem you had with that system, you should have sorted it out in it only without taking out the HDD and putting it in an external enclosure.

Ok, so I have my system and I have 2 operating systems on it. 1 is C:\ and the other is I:\ .Today i turned on my computer and a windows boot manager error thing came up so i put in windows 7 disk and it repaired the system. i go into I:\ (which is windows 7) and came up with disk check. Then it continued normally until it said 'Preparing your desktop'. Then it came with blank blue-ish screen and in the bottom right conner said "This copy of windows is not genuine" which it is. Signed me in to a temp account couldn't access any files. Turns out it was trying to access D:\ instead of I:\ no programs worked. I went onto the other operating system checked it and it said it was I:\ so somehow Windows changed it to thinking it was D:\ not I:\
Any help is appreciated.

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.

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.

Hello all,

I've been trying to find a way to hide my swap partition, but all available information on doing so either leads to group policy editing (which only has various combinations of the drive letters A, B, C, D, E for hiding), drive letter removal (which is an untenable solution given that the swap partition is only usable with a drive letter to tie it to), or registry editing (which is as untenable as the other two).

I have attempted all three with no perceivable solution.


For reference: My swap partition's drive letter is S:

Hi Guys,
My sister has just brought a Dell laptop, (not sure which model), which came pre-installed with windows vista.
The hard drive has been partitioned into drives "C" & "D" - drive "D" contains the system recovery data and is called "recovery disk".

I need to change the drive letter of "D" to something else as they have some software that only runs from CD and will only run if the cd is named drive "D", so I would like to rename the "D" drive to "L" and then rename the cd drive to "D".

I know how to change the drive letters but I'm concerned that in renaming drive "D" the recovery programs won't be able to work if she ever needs to recover the system.

Does anyone have any ideas about this please?

My system will not boot. It gets as far as the Windows XP logo with the 'busy bar' going back and forth, hangs for a while, and then reiterates the entire reboot process. Starting in Safe Mode reveals a hang at MUP.DLL.

The Windows XP Setup program does not recognize the partition as being NTFS formated (my 160GB hdd has two partitions, the second one is ok).

I booted Partition Magic from a bootable CD and discovered that the primary partition has no drive letter allocated to it.

Removing the drive letter from the Recovery (D) partition would cause you to no longer be able to open the Recovery Manager in Windows 7. I'm not sure if at boot/startup (F11) would still work or not. You would have to test afterwards to see. If not, then you would need to add the drive letter back.

After partitioning a hard drive with Partition magic, the two partitions were labeled D: and E:
The boot partition was D:. I used the option to change the boot partition to C:. The software showed a warning that renaming the boot partition might result in not being able to boot. I went ahead reasoning that, at worst, I would have to use a CD to reboot. Well, now the computer won't start (I don't mean won't reboot.

I have a single drive partitioned into 2.

I installed windows 8.1 onto partition C.
I cloned partition C onto partition D using EaseUS Backup.
I used easyBCD to add a boot entry for partition D.

I know if you do two separate installtions through the installer, windows makes the drive letter it boots from into drive letter C. This retains the proper path links and ensures compatibility for all applications.

But with the clone when i boot into drive D, it doesn't rename itself into drive C. How can I get the rename functionality enabled so it works properly?

What I have now is windows starting from drive D, but all the links point to drive C for everything including the desktop.

A:Dual Booting Cloned Partition - Incorrect drive letter


I solved it the issue. It was because that the disk lettering was already enumerated for the other partition on the initial installation. You couldn't change it in disk management since it was in use.

I opened the registry on disk d remotely.

Those keys are what gives the drives the letters, but they have to be removed remotely and not within the installation

I select windows it would go to a black screen hard drive light would flicker for a bit and it would just stay stuck on this black screen When I rebooted and from the operating system select screen accessed the Command Prompt I noticed that the partition where Windows was was no longer on C Instead it was now residing at D and C was the system reserved partition which i think is the boot partition in windows So I'm guessing - and correct me if im wrong - that when i select Windows from the operating system screen it is searching for the operating system in C as it used to be but now somehow that partition now exists as D so it cant find the files and just hangs If this is the case then I suppose I either need my windows partition to reclaim C or i need to change the boot settings somehow to load windows from its new home at d Im guessing the first option is the best way to go back to exactly how things were I dont know how to do either So I'm not sure what happened here when I plugged my hard drive via an external USB caddy it seems to have changed a few things around on the drive like assigning the system reserved partition a drive letter - it shouldnt even have a letter should it As a side note Windows does boot correctly from this laptop - im guessing because when you select windows it restarts the machine and the OS can only see partition - that where windows resides Also I have a run a chkdsk on the windows partition and it came back with no problems

That way you have a choice what to install.
Then run windows update manually.
Check the list of updates for a drive controller driver.
It sounds like it is installing one that isn't working for you.
It would probably be under optional updates.
You should be able to select hide update an click ok

I have two virtually identical Dell laptops running Windows Home Premium.

On one of them I wanted to see what was in the hidden RECOVERY partition so I fired up Disk Manager and added a drive letter. Nothing in the partition made sense to me so I removed the drive letter.

However, windows no longer recognizes the RECOVERY partition. If I run standard windows "Create System Repair Disc", I get an error message "The parameter is incorrect 0x80070057".

The Dell DataSafe program also says it cannot find the RECOVERY partition.

a) Is there some kind of attribute that got changed when I assigned the drive letter and then removed it? If yes, how can I set it back?

b) The laptops are virtually identical. Can I use a recovery disk from one on the other? I'm particularly interested in keeping MS Office 2010 Starter edition intact when I upgrade to Win 7 Pro.

Hi Sekhar, It sounds as if it doesn't matter about the files on D:\ now if I understand you correctly- that was where you had Suse installed. It also seems you can still boot and run Vista.

So it seems that you just need to clean up the partition table.

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?

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.

I've done quite a bit of reading but have not found a specific answer to the title of this thread.  The system reserved partition for Windows 7 is created and has assigned the drive letter D:.  While I have no problem with the system partition
per se, I would prefer no drive letter to be assigned or to able to change it at the very least.

A:Change or remove Windows 7 System Reserved partition Drive Letter

It is highly unusual for Windows 7 to assign a letter to the reserved partition.  It is more likely that someone assigned the letter D: to that partition.
However, you should be able to go to the Disk Management and remove the letter on that partition.

So I inadvertently stumbled onto the disk management program, whilst looking for disk cleanup... and was a little confused to find a 25gb primary partition which was totally unassigned. It won't let me do anything to it other than delete it. So I guess the question I'm asking is, can I delete this partition and assign the 25gb to another drive... or, is this important? I've heard manufacturers often include an inaccessible recovery partition... but 25gb is space I could use...

Hi all,

the other day I switched off the XP restore function after seeing my total drive capacity was out my 2gb. I went into Computer Management > Disk Management and found there was a partition 'unknown health partition'. I downloaded PartitionMagic to merge that partition with the main partition and everything seemed to have worked fine. Now trying to open PartitonMagic again, I get the following error, Init failed: Error 117, Partition's drive letter cannot be determined.
An error also pops up if I attempt to defragment the drive, 'Drive C might be corrupted, run chkdsk /f'. I've done that, no problems found, but I still keep getting the error. Any ideas how to fix this thing?


A:PartitionMagic-Init failed: Error 117, Partition's drive letter cannot be determined

From here (archived)

Compatibility issues
PartitionMagic is compatible with Windows NT, 98, ME, 2000, and XP desktop editions. However, it is not compatible with Windows NT, 2000, or .NET server editions. It crashes if a Windows Vista partition is present, even if it is run from a different operating system, with the error "Init failed: Error 117. Partition's drive letter cannot be identified". However this error can be avoided if the Windows Vista partition is configured using Windows XP instead of creating the partition using Windows Vista or its installation disk. To fix this, all partitions on the hard drive need to be deleted and formatted into new partitions using the Windows XP installation disk, allowing for a working partition for Windows Vista to be created. The same error occurs in some conditions under WindowsClick to expand...

Normally it's best to use the bootup option (Dos) to access PM, sometimes within Windows it cannot find the drive letter correctly

After executing the following diskpart commands to the recovery partition the WinRE image is no longer accessible by ReAgentC and recovery media can not be created:
set id=de94bba4-06d1-4d40-a16a-bfd50179d6ac
gpt attributes=0x8000000000000001
Do I have to manually mount the recovery partition every time I want to create a recovery media?


A:ReAgentC: After removing drive letter and setting GPT partition ID/attributes WIM is no longer accesible.

The Create Recovery Media utility works fine. I just ran it as a test, and it does not unhide the recovery partition at any time during the media creation process. So that partition being hidden is not a problem. I took a screenshot showing Disk Management
after the utility created the recovery on USB.

Are you using Windows 8.1? If so, was it original 8.0 and updated through the Store?
I notice that in some cases, an 8.0 original, updated to 8.1 may show errors relating to recovery. For example, if you try to run recovery, it says no recovery partition present and to insert media! But when 8.1 originally came out, you could run recovery
immediately after without having to insert a disc. Something changed over that time period... perhaps it is related to a Windows Update somewhere. Anyways, if your PC is in this category, it is possible that it is related, and recovery media cannot be made
as normal.

You can do it through the Vista disk management.
Control Panel -System and Maintenance -Administrative Tools-Create and format hard disk drives.
You will have to change the card reader temporarily to something else, to free up D. (x Y Z?). You can then put it back to where it was, whic I would suggest, so that it retains its installed path.

Hi Sparky09,

I'm assuming it is a parallel cabled drive and you have two drives on the data cable. The slaved one should have the jumper on the back set for Slave. The other one will be jumpered as Master. The slave drive must show up in the BIOS in order for windows to see it.

Check your cabling, power plugs, and jumpers then look in the BIOS.

However, neither my main computer (Windows 7) nor my laptop (Vista), recognise the HDD as a 'USB mass storage device', and I have found it listed instead as a hard drive, but with no drive letter (apparently).

It has been suggested that I allocate a drive letter between N and Z to this old HDD, in order for my machines to recognise it properly, but wherever I look, I'm not given the option to do this.

Other than taking a hammer to the old HDD, can anyone offer any advice, please? I'd be very grateful.

It doesn't matter. That just means something else is taking up the D letter.

Right Click on the color strip of the drive and click 'Change Drive Letter and Paths...'

Be sure nothing is taking up the D slot or else D would not be an option.

Note that it is booting correctly, which comes as a surprise as I thought it always HAD to boot from drive "C". Looking at the properties shows the boot drive as drive 0 and the other (now called "C") as drive 1.

A:Solved: Skipped drive letter

this happens quite a lot when you start moving things around or adding/removing storage hardware. I've seen many posts just like yours, I guess it's just a bit too confusing for XP to sort out all by itself. Drive E in your case was at some point earmarked for the 2nd partition on your first hd device, so xp has reserved it, in its ultimate wisdom.

The simple way is to right-click on my computer, select 'Manage' and select the appropriate drive/partition, there's an entry for the drive letter which you can change there.

This doesn't, however, come without its own problems. I've also heard of some instability in systems where people have manually changed the drive letters. I can't speak from experience as I generally just go with the flow and don't worry too much about what letter = what. Truth is I don't really care as long as it works.

The only 100% safe and reliable way to have all the drive letters in order, no gaps, is a complete reformat (from delete partition) and install of XP, a bit drastic I'm sure you'll agree just to get the letters neat and tidy.

I have a question.

I formatted a partition of my harddrive but in the end not only a partition was formatted but the next partition also was gone.

Meaning: the data is still there, but the NTFS partition isn't recognised anymore by Windows, and in diskmanager the space is now ready to assign new partition.

In a data recovery software, I saw the not recognised partition was still recognised as 'NTFS'.

What can I do?

The best scenario would be to simply tell Windows somehow, there is partition with NTFS and it should assign a letter to it.

My windows 7 is suddenly applying a drive letter to the system partition, and removing the letter which causes the "new disk inserted" window to keep popping up every half second. In Disk Manager the drive letter appears and disappears every half second.
The only way I've stopped it is to permanently apply a drive letter, which means it is now visible in windows explorer.

A:System reserved partition becoming "visible" and intermittently assigned drive letter by Windows

I assume by 'system partition' you really mean the hidden system restore partition installed by your PC builder? If so, then after I just fired up Paragon Partition Manager to see what it makes of that partition on my Win 7 PC, I find the partition is Primary, NTFS, active, not hidden, volume name WinRe.

The main interesting thing is the volume letter seems to be set to '*'. It appears as (*) rather than (C: ) as the OS drive does. Furthermore, the main menu has a 'partition' tab, where one of the options is 'assign drive letter', and the next option below is 'remove drive letter' which is currently greyed out.

Looking at the standard Windows computer management, storage, disk management, I see a similar picture, except there is no volume letter at all (apparent in that window anyway).

Quite how the partition gets identified in that way is a puzzle, but you might try a free partition manager, such as gparted and see what that says, and possibly allows you to change. As I say above, Paragon Partition Manager might let you de-assign a drive letter but I dont dare try it myself

Well firstly if you want to upgrade your XP Home install make sure you run the XP Pro setup from XP HOME!! Then it should tell you that your current OS is older than the one on disk, and offer you the option to upgrade.

NB: When you boot into XP you should notice that the drive letters will be different (usually the current system drive is associated to C:- so in XP, your XP part will be C, but in Vista/7 your vista part will instead be labled C:).

As long as you've booted into XP, and run the upgrade setup from there you shouldn't encounter any problems, and it shouldn't touch your Vista partition.

The only issue you may find is that the XP Pro setup might re-write your boot selector with the old legacy one used back in XP, so you wont be able to boot into Vista/7, but that can be fixed by either using EasyBCD in XP to restore the BCD boot manager, or by booting your PC from the Vista/7 disc and selecting the option to repair startup issues.

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,
