My brother built this PC. It was not bought from Dell or HP or anything like that. What would I do to go about finding my MBR? Sorry, I don’t know anything about MBRs so you may have to walk me through this a bit =/.

Also I have run MBAM twice, the first time it caught things and deleted something in the config\system folder so I couldn’t start the HD. After I recovered that I was able to run it a second time with no luck. I have also run avast and avg, both multiple times.

Thanks again
