After installing the updates this week of 10/09/2011, my Windows 7 64 bit will not restart. I've gone thru all the repair apps several times, and it says I do not have a restore point. I get an error message of 0x0, and am told to remove a camera or music device neither of which are connected. I wanted to re-install Windows in the repair mode, but 7 does not seem to do that as previous systems. My only alternative I can see is a clean install which I really do not want to do. Any ideas.
