>> My laptop runs XP Tablet edition. There is no disk for it. <<

Which make/model?

The oem distribution disks are critical for tablet os pc's... most
shipped with them, some oems sell replacements... if you have neither,
you might see if it's possible to generate a restore cd set... it might
still be possible, but it would be worth the attempt.

If you don't have any of the above options, you might loose your tablet
functionality as there are no sources other than the oem's for the os
cd's a keys and we know some have already abandoned some of their models.
