Hello,

I recently started my computer and it gave me the message "Missing Operating System"

A little background of the problem. My hard drive had some weird problem where every once in a while, maybe once a week/month it would stop getting detected in the bios. If that happened while the computer was running it restarted the computer.

That happened and I checked the bios and the sata hard drive was not detected. What I usually do in this situation is close my computer for a few minutes, then start my computer up again and it gets detected in the bios. So windows screen pops up and it is loading. But I though it was taking too long on the loading screen so I pressed the restart button on my computer. After that happened, I got the "Missing Operating System" error.

My Sata hard drive is still detected in the bios.

Steps I have tried:

1. Changing Sata port
2. Windows Vista Startup Repair
3. command prompt chkdsk /f and /r

I finally fixed it after doing a bootrec.exe /fixmbr and then bootrec.exe /fixboot
