I am fixing a computer and I am having issues with the drive letters. Last time I reformatted and reinstalled windows xp, my D: drive was changed to C:, and I was forced to install XP on D:. This is one drive with 2 partitions.

I am about to be reformatting again and I would like to install windows on C:, but in windows, DOS and other partition management software, the partition I want to install windows on is still D:. Is there a way to change the drive letter from D: to C: and C: to D: without involving windows?

I have data currently on C: (I want to make it D: ) that I need and can't move it to another drive. Deleting all partitions and starting fresh is not an option.

Thanks in advance for your answers!

Boot the computer with the 2000/XP CD in the drive and allow setup to begin. When the screen appears showing the existing partitions and unpartitioned space available on the computer you should see a drive listed in the lower portion of the screen. Now you'll see all the partitions listed that are currently on the drive. To delete all the existing partitions hit the 'D' key followed by the 'L' key. The screen instructions will be visible to guide you through the process.

Once all the existing partitions are deleted the display will show the total unpartitioned disk space.
If you only want one partition then hit enter and the entire disk space will be allocated to a single partition and you'll be taken to a screen where you select a file system.

If you want to create one partition of a specific size or several different partitions then do not hit the Enter key. Instead, hit the 'C' key to create a partition. Hit 'Backspace' until the cursor moves to the first digit location. Enter the size of the first partition to be created. Repeat the create partition process as many times as you want until either the desired number of partitions has been created or all available drive space is allocated to partitions.

Once all the partitions have been created, use the 'Up' arrow key to select the C drive partition and press the 'Enter' key to install XP to the partition. It's necessary to choose a file system and format the partition before the installation can proceed.

I can't loose the data on C: (the drive that I want to be D: ), so deleting all partitions and starting fresh is not an option. Thank you though for your quick response!

your Data on C: drive to CD/DVD. Or if you have access to another hard drive use that. ;)

But if you are attempting to install to what is the Primary Partition or Master Drive all you need do is delete that partition and format it. Do not allow the Windows Installer to start the install after it is formatted you need to restart the Windows Installer so that is allows the Partitions to revert to Hardware Assigned Drive Latter's and not software assigned drive letters.

But you really need to backup the data in case anything goes wrong with the install as you could loose everything and it can cost a lot of money to recover. If the drive was to get wiped and you have Critical Data on it be prepared to be looking at at least $26,000.00 or the cost of the recovery software and up to a week to recover your data.

What should and what does happen are two completely different things and you always need to Backup before doing anything like this to any computer System.

Both DOS and the Windows Installer will ALWAYS designate the primary DOS partition on the first hard drive as drive C:. Further, as you can only boot from the primary partition, if the first physical drive has no primary partition and the second physical drive does have a primary partition, you can end up with D: or a higher letter as the boot drive.

There are no options or ways to change that. Other than by using a partition manager such as Partition Magic to change which partition is the primary DOS partition and which is the extended DOS partition with a logical drive. Of course, even with a partition manager, you might loose your data, so you MUST back up your files first.

So:
Back up your files.
(if needed, either install the drive in another computer or in a USB drive enclosure.

Delete the logical drive(s).
Delete the extended partition.
Delete the primary partition.

Start over:
Create the Primary DOS partition first.
Install XP.

Create the extended partition in disk manager.
Create and format your logical drive(s) in the extended partition.
Restore your files from the backup.

Thank you all for your answers, you have been very helpful. I found a friend who allowed me borrow some space on his hard drive. After copying my data, I did as I was told and it worked. THANKS MUCH!!
