Alright guys, I'm back. I got everything backed up, but I'm having trouble installing windows.
I unhooked my other hard drives, so there's just the one in there now. When I try to install, it first takes a ridiculously long time to get into the setup, and then it never completes it through - it always reboots before it finishes and starts over at the Install screen. I was originally using a CD, then I tried downloading a new iso and have it booting from a flash drive, but I'm getting the same results. I've never had this problem trying to install windows before - I don't know what to do.
