Somehow I missed the video you posted in post #34. I think my mind is conditioned to skip over anything that isn't text for some strange reason... lol. Anyway, thanks for that video. I watched it and followed the instructions but got hung up here:
x:\Sources>Bootrec /fixmbr
The operation has completed successfully.
x:\Sources>Bootrec /fixboot
The operation has completed successfully.
x:\Sources>bcdedit /export c:\bcdbackup
The store export operation has failed.
The requested system device cannot be found.
I tried using different drive letters (d, e, f and g). I tried different BIOS boot settings, to no avail.
So near, so far....
