Go Control Panel>Administrative Tools>Computer Management>Disk Management>Help and read about all the different kinds of partitions. From there, you should be able to figure things out. I think a better alternative is to use a different drive, but you will be able to run both on the same drive/different partitions with no problem. If interested in the alternative check out my "Here's how it went/goes for me" thread--if you have a laptop. And, of could you can do the same thing with a desktop. I am assuming that you are running XP right now. The needed help files may non be available on Beta 2 yet.
