I have just purchased a pc with vista pre installed.I have a NEW disc with win XP Professional edition which I would prefer to have on the new machine.It currently has a 250 Gig hard drive. What would I have to do kinda step by step, to remove Vista, reformat the HD into say C,D, and E drives,and also load win XP Professional back on?.. This is not a copy, but a newly purchased XP Pro disc. I have reformatted a PC "YEARS AGO" but then I had the floppy to install in the A drive, whats the proceedure now?....Thanks in advance. Phil.
