How to uninstall Ubuntu on dual boot Windows XP using Windows only

My dual boot Ubuntu installation on Windows XP got hopelessly trashed. Endless command line errors upon booting. After much searching, I found an easy way to uninstall it using Windows only.
It took me about three minutes and it worked flawlessly. Hope this helps someone else. (And now I can reinstall Ubuntu!)
Quick instructions: (detailed instruction follow)
A.) Use Disk Manager in Windows to delete the Ubuntu partitions.
B.) Boot off your Windows XP CD.

1. Choose “Repair”
2. When it asks for the installation number, I put in “1″, and it worked fine (you may want to test this first to be sure.)
3. Enter Admin password.
4. At the command prompt type “fixmbr”, then confirm. Windows will overwrite the dual boot info in the MBR that Ubuntu put there.
5. Reboot!
