I just bought XP professional with sp2. I've been reading online on how to downgrade. I first back up. Can I use Norton Ghost to back up or do I actually want to back up Vista? Do I back up with CDs? Should I wait for my new Seagate 500 GB External back up Drive system because my present back up is only 150GB? The Toshiba is 168GB full only 60GB used. I don't want to have anything to do with Vista. The easiest is to partition the hard drive. I guess the c drive and the d drive. Have Vista on d drive, the one we don't use often and the XP on the c drive. I am guessing a lot and need professional expert guidance. I can most likely only do the easiest way. What's unclear, how do I separate the Vista on the d drive? Will it say on Norton Partition Vista in a folder? Do I need Norton Partition or not? As you can see I am very unclear and not sure I got good advice.
