I removed McAfee, rebooted, and let windows install some updates. Then when trying to boot again, I get stuck just before the welcome screen loads. It has the blue background you see on the welcome screen, but no text or list of user accounts. Only the background, and the cursor.

I have tried booting in Safe-Mode, but it seems to ignore F8. I know it's not not me as I've booted into Safe Mode hundreds of times, and I know it's not a broken key because after pressing it a few times, you will hear a system beep every time you press the key.

I have also tried letting it do Startup Repair, but when trying to load the Startup repair, I experience the same problem.

Any ideas?
