Is there an easy way to change the drive letter on the system driv

[Guest]

This is similar to, but somewhat different from a previous post. Just
installed a virgin copy of WinXPPro on a home-built computer with one SATA
and one IDE drive (with multiple partitions on the IDE drive). BIOS was set
to look for the SATA drive first; however, when the install on the SATA drive
had been completed, the system drive was designated as "I". If I temporarily
disconnect the IDE drive, is there a relatively easy way of re-configuring
the system to "C" without doing a complete re-install? The standard Windows
re-assignment procedure can't be used on a system drive. Can one use the
Windows Recovery Console or some other utility instead? I was several hours
into software installation before I noticed this problem. I would like to
avoid doing a complete re-installation, but if no one has any good
suggestions, I will probably bite the bullet and re-install everything.

If your system drive letter used to be C: then you can safely do this:
Run regedit.exe, navigate to HKLM\SYSTEM\MountedDevices and
rename \DosDevices\I: to DosDevices\C:. If "C:" is already occupied,
delete it first. You must reboot the machine for the change to take effect.
