    All of a sudden I can't boot into Windows. After I select my Windows drive, it goes to a black screen with a flashing cursor for about 4 seconds, then reboots itself automatically. I can boot into it fine in VMWare, so most likely something screwed up the MBR or GPT or whatever Windows 7/Boot Camp uses. Any ideas on where to start with fixing this? Maybe use fdisk to repair the MBR?

    Here's a report from Partition Inspector, if that helps:

    Quick update: if hit F1 right after selecting my Windows partition, I can get into the Windows boot options menu. Unfortunately, as soon as I press F8 to select advanced options, it goes to black and restarts. :(

    Fixed. Swapped out my HDD for my DVDRW, loaded up startup repair from the Windows 7 disk, and did a bootrec /fixmbr and bootrec /fixboot. Problem solved.

    I hate it that you can't boot from a USB device. :(
