I have several computers and one needs to be reformatted. The problem is that I have lost the recovery media for it. What I am asking is if it is possible to use the recovery media from a Dell desktop to an HP laptop. Both have the same operating system (XP Home) and I am assuming that since they were manufactured they have OEM versions on them. So, should I be able to use the dell cd to reinstall xp home and change the product key to the one that is on the computer once I have installed it? Thanks.
