Blue Screen of Death (BSOD) boot loop
Windows 7 froze up on me while "checking for updates." After holding down the button to hard reboot the machine, I was greeted with this...
Holding F8 to reach the advanced boot options works, but any option I select there (Safe mode, etc.) returns me to this screen and then to an automatic reboot, back to this screen, reboot, etc.
DIY attempts at repair temporarily led to a "Bootmgr is missing..." error which was resolved in another discussion thread. The specifics of my machine and the details of that adventure can be found here: Bootmgr is missing...can I join the club?
