Is this a full legit copy of XP? If so is it for a specific PC like a Dell or HP? Are you using it on that type of system? The Dell, HP, Compaq and other Vendor XP Discs are taylored to their systems and wont recognize many other types of mobos and such. So if that is the case need to get a different copy of XP.
