I have a strange problem. I read about the BOOTMGR is Missing problem here, and the associated fixes. I get the BOOTMGR is Missing error message, but only sometimes. When I do a control, alt, delete as the error instructs, the computer then boots up just fine usually. All will continue to be well for a while, and during reboot, it will happen again. I've run the Windows 7 rescue disc startup repair option, but it says a problem cannot be found, yet obviously something is going on. I've done the bootrec /FixMbr, bootrec /FixBoot, and bootrec /Rebuildbcd commands at the DOS prompt. On that last command, it told me the number of Windows installations was 0, which obviously isn't right. I'm confused and frustrated by this. Help!
