I have a Dell computer (Desktop) that keeps getting the Boot manager is missing error. I can go into safe mode with command prompt and perform the bootrec.exe /FixMbr and bootrec.exe /FixBoot and that seems to fix the problem temporarily. This computer is dual boot with Vista Home Premium (factory) and Vista Ultimate was added. I have the Ultimate DVD if that helps. What do you need from me first to diagnose this beast of mine?
