PST, I think I mentioned this elsewhere, but Windows tends to use %windir%, %systemroot%, etc rather than C:\windows or C:\, etc. Therefore, I personally have NEVER had a problem with installing Windows XP on a non-standard drive. Unlike 9x which needed to be on the first primary partition, I have even installed XP/2K on logical drives and never run into trouble. However, as usual, try all this at your own risk .
