BOOTMGR image is corrupt. after updating bios

[Metal99]

I recently updated the bios on my EVGA 790i Ultra SLI board to the latest version. After restarting the computer, I cannot get windows to start "Bootmgr image is corrupt" or "The file is possibly corrupt. The file header checksum does not match the computed checksum."

I put in a the windows 7 64 bit disk to try and boot from it, and i get to the setup menu. I try to choose Launch Startup Repair (recommended) but the system keeps going back to the WIndows Error Recovery, and will not get into any setup mode. I try to launch normally but it keeps restarting itself.

I have 2 striped raids, one has the windows drive, and one with other various files.

I have an option in my raid setup to clear mbr, but i dont want to lose my data, is that going to mess up everything even more?

I think i fixed it. I should have reset the bios defaults after flashing. Then enabling raid, and changing boot priority, adjusting timing, multiplier and voltage.

Next step, backup everything on my raid 5 array.

May I ask why you are using RAID with WIn7?

The raid 5 is on a separate machine with windows server 2008, 4x 1.5tb drives. I have the stripe (raid 0) on my windows 7 machine. Supposidly i get better windows performance, but right now it boots slower than my laptop with a single 7200rpm drive. /end rambling
