Uninstalling Windows ME

I decided to finally get rid of Windows ME which came default with the computer. Before anything, i installed Windows 2000. Now i have two OSes that i get to chose from everytime i start my computer. Any ideas on how to remove Windows ME? Add & Remove Program; dosn’t seem to work as it does not appear. I also only have the “Reinstall Disc” for Windows ME, no boot discs or anything.
