I have a laptop i just purchased from hp, it was mandatory by them that i had vista on it. I do not have a windows vista cd, instead i have windows vista on a partition on the hard drive. I would like to get rid of vista and have xp on my laptop, but when i put my xp cd in there is a compatibility error that comes up and stops me from starting the reformatting process. Also in formatting vista to xp will i loose any drivers that would be on the computer for example, my touchpad(mouse), my dvd player,sound card,network stuff, blue tooth. Any information on this subject would be greatly appreciated thank you.
