Oh, bother.
Oops. I kinda sorta wiped my C: drive. In theory, this shouldnt be a problem, as I copied it completely before I wiped it, half-expecting my RAID 1 initialization to require fresh drives. Funny things, theories. I can boot the copied drive, but I get no interface - I can only run things with Task Manager; even then I cant seem to get Networking to run at all. Wah. I really dont wanna reinstall.
