Fellas......I have WinXP Pro on a Dell machine which came with one 40GB drive. I repartitioned it with Partition Magic and it works fine. I then repartitioned another Dell I had and reloaded the operating system from the Dell Recovery disk. It loaded fine into the partition of my choice and did not remove any other existing partitions. In fact, it appears that it loaded a generic non-Dell version of WinXP, so no proprietary stuff was present (not even the Dell wallpaper). Try Partition Magic 7.0.1. It worked fine for me although there are a few glitches with it......you really want to partition your drive, otherwise you'll be waiting for days while you defrag your giant hard drive......... Krel
