    Hi TSG

    My comp was messed up so I decided to clean reinstall xp pro, my hard drive was split into 3 partition, C, E backup and L photos and bits, at the point of the install were you decide,delete our make partitions, I decided to delete L as it was not needed and clean install onto C, leaving E with my docs and data, the install went fine, when I looked at my drives in admin tools the C is marked boot and E system, I was going to delete E and make new partitions, but because it marked as system, can not delete it. How did I do this and is there away to put it all back onto C, without reformatting.

    It is possible to change a system drive letter, however I do not recommend you do so. It is an involved process and any installed app will need to be reinstalled anyway. From your post, it would appear that you now have unallocated space on the disk anyway [L drive that was deleted]

    I would backup your data and clean install the os; deleting all partitions and creating what you want. If you really really want to change a system drive letter, here are the instructions. Again I do not recommend doing this.

    Change the System/Boot Drive Letter
    WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

    Make a full system backup of the computer and system state.
    Log on as an Administrator.
    Start Regedt32.exe.
    Go to the following registry key:
    HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices

    Click MountedDevices.
    On the Security menu, click Permissions.
    Verify that Administrators have full control. Change this back when you are finished with these steps.
    Quit Regedt32.exe, and then start Regedit.exe.
    Locate the following registry key:
    HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices

    Find the drive letter you want to change to (new). Look for "\DosDevices\C:".
    Right-click \DosDevices\C:, and then click Rename.

    Note You must use Regedit instead of Regedt32 to rename this registry key.
    Rename it to an unused drive letter "\DosDevices\Z:".

    This frees up drive letter C.
    Find the drive letter you want changed. Look for "\DosDevices\D:".
    Right-click \DosDevices\D:, and then click Rename.
    Rename it to the appropriate (new) drive letter "\DosDevices\C:".
    Click the value for \DosDevices\Z:, click Rename, and then name it back to "\DosDevices\D:".
    Quit Regedit, and then start Regedt32.
    Change the permissions back to the previous setting for Administrators (this should probably be Read Only).
    Restart the computer.

    Hum, I think I will take your advise and reformat, and delete all Partition, I do have back ups of my back ups. Out of interest how did E become a system partition when I installed onto C.

    Thanks for your reply.

    Do you have an internal ZIP or flash drive? . . that will do it . . you can disconnect it for the installtion to avoid a repeat.
