You can't "uninstall", you can format the partition from within XP, or just clean install XP with the XP CD, and while you're creating a new partition, format both, and merge them, and then create a new one, add XP back on, and add your data back from the DVD, if you're sure the drive is clear of all important data, a clean install of XP would be the easiest thing to do.
