So I found out all of my programs that run in windows XP are also compatible with windows 7, and want to either upgrade or clean install over the XP partition. The one problem I see is that my XP partition is FAT32, and I have 2 other partitions, one is the mac snow leopard partition, and the other is a FAT32 data partition. I had to do some trick to be able to get this third partition, and while I don't remember exactly how I did this, I remember it involved changing some environmental variables. Long story made short, can I install Windows 7 over Windows XP and be able to boot up as normal, or should I start from scratch, backup all data, install snow leopard, bootcamp, and the windows. Thanks.
