> SUMMARY
> This article describes how to change the
> system or boot drive letter in
> Windows. For the most part, this is not
> recommended, especially if the
> drive letter is the same as when Windows
> was installed. The only time
> that you may want to do this is when the
> drive letters get changed without
> any user intervention. This may happen
> when you break a mirror volume
> or there is a drive configuration
> change. This should be a rare occurrence
> and you should change the drive letters
> back to match the initial
> installation. NOTE: Please be aware of
> the following issue related to drive
> letters:

> To change or swap drive letters on
> volumes that cannot otherwise be
> changed using the Disk Management
> snap-in, use the following steps.
>
> NOTE: In these steps, drive D refers to
> the (wrong) drive letter assigned
> to a volume, and drive C refers to the
> (new) drive letter you want to
> change to, or to assign to the volume.
>
> This procedure swaps drive letters for
> drives C and D. If you do not need
> to swap drive letters, simply name the
> \DosDevice\letter: value to any new

> 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.
> Check to make sure Administrators have
> full control. Change this back

> Go to the following registry key:
> HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices
> Find the drive letter you want to change

> "\DosDevices\C:".
> Right-click \DosDevices\C:, and then

> NOTE: You must use Regedit instead of

> Rename it to an unused drive letter

> Find the drive letter you want changed.

> Quit Regedit, and then start Regedt32.
> Change the permissions back to the

There is a lot of big words in there, probably a bit complicated for one
who can not follow simple instructions!
