I have seen this problem before. I used an old windows 98 boot disk and re-format the hard drive the old fashion way with fdisk. once you have completed that set your BIOS 1st boot device to CDROM and put your XP disk in the drive...reboot and when prompted to boot from disk do so, then follow the instructions. I did this for a friend with the same issue. worked great.

Oh and please don't go to the Geek Squad, they do NOT know what they are doing. They keep me in business following them around fixing their mistakes!

Okay, some of what that guy said makes no sense because it's already very clear that you have already HAD XP on the computer... so what you should do is locate the XP disc that came with the computer. When you start your computer, enter the boot menu and change your boot order to boot from the CD drive first. It should restart, pop the XP CD into your computer and follow the instructions to reinstall XP. It's not that complicated. If all else fails, go to BestBuy %26 pay the GeekSquad to do it, they know what they're doing.
