OK, I need help "PLEASE". I got a new Laptop "HP Pavilion d4t" came with "VISTA HOME" I have my old Laptop that has "XP Pro" I like it better. Q: I need help, in getting rid of "VISTA" and install "XP Pro" in new Laptop? Came with a partition for "re-install to factory specs" I would like to keep it, (just in case, nos sure why) I have try to do it in another Laptop (that the HD went bad) and couldn't do it. Not sure if this will void the warranty? Can any one with patience will help please? PS. I hame a OM XP Home Edition; also a Windows Operating System Back-up (XP-Pro)that came with the Dell, will any of this work? Thank you Microsoft YOUR VISTA stinks!
