I installed Windows XP onto a 200GB hard drive when I built my computer. I installed a 500GB hard drive later for use as storage. I didn't partition either when I installed them. I am now trying to reinstall Windows on the 200gb drive with a partition so it will (hopefully) quit freezing up on me. When I try to partition it during the setup, though, it won't let me. It tells me it can't be done because files needed for the setup are on the drive. I tried installing Windows to the other drive and then reformating and partitioning the first one, but that didn't work either (same reason). Any ideas?
