I want to upgrade from Home to Pro and just failed doing so. It works fine up until it reboots. After rebooting it hangs on the "Starting Setup" screen about four bars away from completion. My dad(who is experienced in this kind of stuff) seems to think I need a driver for my SATA hard drive. I'm not quite sure on what to do. Here are my specs: 320 Gb Hard Drive(I forget the make, but I know it's SATA) Socket AM2 Asus m2n4 SLI AMD 64 x2 3800+ Dual Core 1Gb of RAM nVidia BFG GeForce 7900 256mb GT OC video card Windows Home SP2 P.S. I don't have a floppy drive.
