Reinstalling XP questions

I have a Toshiba laptop that I have had for about 2 years.

I want to reinstall windows on it but it never came with a actual XP disk. I bought it new from newegg.com. It runs Windows XP tablet edition.

There are only 2 disks that I have for it, the first lets me install Toshiba programs that come with the computer. I see nothing for xp itself.
The second is somewhat strange. When I put the disk in nothing happens. I looked to see what was on it and I see this:

Is this disk what I need to reinstall?
If so, how should I go about doing it. Or is there something I am missing.

Is there anything I need to know before trying to reinstall without the actual disk?

Thanks for any help,
