A while ago, I installed xp on my desktop, but I was silly and kept 2000. So, everytime I boot, it asks me which OS to use. I think I went into my virus-ridden 2000 once since then. Now, I'm running out of space and want to erase it. I thought it was on a different partition, but when I booted from my xp cd, there was only one partition to delete. I don't have a 2000 cd or any idea how to do this. please help.
