I originally had XP x64 Pro installed on my PC. I then installed x64 Windows 7 Ultimate on a second HDD. Dual booted great. STart my PC and got asked which one I wanted. But default was always Win7. Which was weird because I thought that the first install was always the primary OS. But anyway, I had to clear my CMOS today, and didnt think about it, but when I started my PC again, it says BOOTMGR is missing. Press Ctrl + Alt + Del. I tried a repair from the Win 7 disk and it says its fixed, restart and the same issue. I tried all the normal fixes from the XP cd and still them same BOOTMGR missing error. Any help would be greatly appreciated.
