Hi, I have a Dell XPS Series 4 PC and I have Windows XP Pro on a 250GB Maxtor Hard Drive that came with my PC and I just added a second Hard Drive that has Vista Home Prem. on a Seagate 250GB Hard Drive. I want to be able to login into XP and Vista separately with out having to reformat either Hard Drive. Right know the way I have it setup is that I have to open my tower and switch the cables from the Maxtor Hard Drive that as XP on it to the Seagate Hard Drive that has Vista on it which is a pain to do every time I want to switch between using XP and Vista. Is there any way to boot my XPS PC so I can chose between going into XP or Vista? I would appreciate any help I can get. THANKS.
