Hi, I reinstalled my Windows 7 Ultimate 64 bit, and after about 15 to 20 days it gives me the "BOOTMGR is missing Press Ctrl+Alt+Del to restart" message when i try to turn on the PC. Now I have 2 hard discs and when I get this message I disconnect the drives from the motherboard and connect them to different ports (or whatever they are called) on the motherboard and the OS boots normally after that, but after 15 - 20 days I get that message again. I tried repairing boot problems with the Windows 7 disc, but it didn't work. Please help.
