After updating the BIOS, Windows will not boot. It will also not repair or reinstall from the repair disk. I cannot even boot Windows from the disk. I've checked my boot priority. That's not it. I've also rolled back my BIOS. No difference. I'm really at a loss here.

Try going in to BIOS Setup again and look for "Load Failsafe Defaults" or "Load BIOS Defaults" and activate that.
Then "Save & Exit BIOS Setup" (F10).
Incidentally, you should only update the BIOS if the update fixes a specific problem you're experiencing, or if it adds a new feature you really need. Don't do it just because an update is available. Updates are not compulsory!
Same rule applies to device drivers.
