You should be able to put the Windows CD in the drive, boot it, and it should take care of everything from there.
If this does not work, that is probably beause your computer is set to boot from Hard Drive first and only look at the CDROM if that boot fails. Simply enter the BIOS and set it to look at the CDROM before the hard drive.
On a side note, you can run those games under GNU/Linux using one of two windows compatability layer applications: wine (free) or Cedega (easier and better but you need to pay for it). That way you can keep GNU/Linux and still run those games. There are many reasons you may wish to do this (higher security for your kids and lower cost for you, for example), but it requires a bit of a time investment on your part.
At any rate, good luck!

I just bought a new Athlon pc 2.4ghz that I didn't realize it came with Linux preinstalled. Because I already have a bunch of kids games I just want XP on there. I have XP install media. How do I uninstall Linux to then prepare for a clean XP install. Do I need to change settings in the BIOS?
