You'll have to locate all the drivers for your HP (the XP one's - not the Vista one's). Once that's done, use a disk utility from the manufacturer of your hard drive to prepare the disk by wiping it clean. Then you should be able to install XP without any issues (make sure to have the drivers before starting this - otherwise you'll have an XP computer that doesn't work very well due to missing drivers).
