I just recently updated my windows 2000 to xp. When I did this I tried to format my computer but it didn't work. I didn't really care that much so I installed xp. Now when I start the computer it gives me a choice of loading xp, 2000, or windows. How can I get rid of this? I don't want 2000 on my computer anymore. When I turn on my computer I want my log-in screen to come on.
