Corrupt MBR. Operating system: Unknown on (Unknown) Local Disk.

Hello, I'm trying to find solutions as to fix my corrupt MBR.

I am running Windows Vista Ultimate 32 bit. I've tried to run a Startup Repair, but I've had little results as the System Recovery Options does not detect my Vista operating system. I have tried  to Load Drivers but I don't know which or how to load. In lieu of that, I have tried the Startup Repair, and I have tried a Bootrec.exe /fixMBR, Bootrec.exe /fixBoot in the Command Prompt.

In running the Startup Repair, the diagnosis it comes up with is:

Root Cause found:

MBR is corrupt.

Repair action: Diskmetadata repair

Result: Failed. Error code = 0x57

Time taken = 16 ms

And in running the Command Prompt, the issue I come across is:

A device attached to the system is not functioning.

If I could recieve any advice, it would be greatly appreciated. Thank you.

Hi,

If you received that when trying bootrec /scanos it means there were no Windows Installations
found.

If you tried all of those and no help then the drive or controller has an issue.
