Well, I think it's game over, and I should reinstall, and on a new drive. I ran the fixlist, and rebooted. I installed the available updates. 8 of 11 supposedly installed successfully, but there was no restart request. I couldn't run sfc until I rebooted. After the reboot, I'm getting a 0x6b BSOD. I've tried Startup Repair. It says it fixes something and to restart, but I'm back to the BSOD. Even if I can get back into Windows, it seems like there may be too many problems for this OS install to work through.
