Do you have the XP cd? You boot from the XP CD. It will ask you if you want to do a fresh install of xp. You say yes. then when it gets to the partition list you delete all the ones in the list, then create one. then after that it will promt you to format using the ntfs file system, it will format then reboot and the installation will begin with xp. just follow the installation. Make sure you have all your drivers ready on a thumb drive or cd. network, video, sound, ect. This was lazy. holler on aim if you want me to walk you through. ill be on all day tomorrow.
