Seems like I was able to recover the Windows directory, same issue at start up. Boots up into Windows environment for a moment, shows a cursor (that is moveable) and then screen goes black and machine restarts back to pre POST.
So I'm curious what repair steps now, trying not to loose any data of course. MFT Repair seems to make sense as the boot sector seems like its intact or I shouldn't have been able to boot into a partial windows environment at all. When looking at the partition with TestDisk though, I'm given warning.

Sectors are identical
I'm getting the feeling that either these warnings mean nothing (don't recall them from previous TestDisk use though) or that its only reading a single drive in the RAID from the Dell PERC S100 controller. Im not familiar with "re-writing" boot sectors on a volume that spans across multiple drives in a RAID. Is there anything special to this? If somehow TestDisk is recognizing this volume as 2 separate drives, could irreparable damage be done if re-writing a boot sector or MFT repair?
