if we assume that you have XP installed on C and then did the dual boot
setup in the normal fashion installing Vista onto D then by removing the XP
drive you are breaking the dual boot and as such will not be able to boot at
all.Uninstalling XP is simply a matter of formatting the HD ...by means of a
boot floppy or running the XP installation as if you were reinstalling and
doing a format before the actual install and then quitting the install.

After you install your new drive you will have to do a "startup" repair off
the Vista Disk.
