I don't see how a laptop, even a Tiny, would have come with a "corporate
edition disk" that was burnt. It sounds very much to me like your so-called
original XP install was not what came with the Tiny laptop at all. However,
it really doesn't matter at this point. Your options:
1. Find out what company has taken over the Tiny warranty work. Contact them
and see if their involvement extends to providing restore disks for that
2. If the answer to #1 is no, you might see if this company has restore
disks for your computer:
3. If the above doesn't help you, then if you want to run XP on that machine
you'll need to bite the bullet and buy a retail copy. Naturally it will
come with its own Product Key which is what you'll use to install the OS.
Hopefully you have drivers for the Tiny.
