XP Tablet Edition is a special, separate release, based off XP Pro. No, a vanilla XP disk, of any other ordinary edition, will not install the tablet extensions.

Sounds to me like you need a new hard disk, possibly, /and/ a copy of XPTE.

Notebook hard disks are quite cheap now. All you need to know is if you need PATA or SATA. I'd give up hope of any of the freebies on the original CD, though.

But if you can get your money back, go for it.
