I recently updated my BIOS to fix some BSOD errors that the BIOS update was supposed to fix. Unfortunately for me, the update messed up the RAID 0 drive configuration - specifically, two of the three drives were no longer shown as part of the array.
After scouring the web, I followed someone's advice and removed the one remaining drive from the array and then setup the array exactly as it was in the past. After boot up, I got the 'Windows failed to start...' message.
From here, I downloaded and ran TESTDISK which showed that the original partition is just fine - everything appears to be where it should be. There is, however, another partition that TESTDISK shows:
Type: MS Data (marked as primary)
Size: ~ 100MB
This partition contains a directory labeled EFI and underneath that are two more directories: Microsoft and Boot. My guess is that this is the UEFI directory, but I do not know much about UEFI at this point.
I can get into the Windows 7 recovery mode and get to a command prompt. From here, the EFI partition shows as Drive C (which I've never seen before) and the regular windows partition shows as Drive E (don't know if that matters or not, but I thought I'd mention it anyway).
Running bcdedit returns with "The boot configuration data store could not be opened. The requested system device cannot be found."
Any help is greatly appreciated!
