I may soon be setting up a new PC w/Vista Ultimate
and XPpro on a single drive. I want Vista on C and XP on D. But I'll need to install XP first so Vista will recognize it and create a proper dual boot file system.

I can easily partition the drive to whatever I want before the installs but I can't recall if I can make XP install on D initially or will it default to C?

(reason I want Vista on C is because it will always see itself as C and having it there will simplify using Acronis Trueimage.)
