Automatic repair has failed 3 (+) times.
I made the next move to attempt fixboot. First I targeted the EFI partition as described here: How to repair the EFI Bootloader in Windows 8 - fixedByVonnie
This went well, but fixed nothing.
Next I just attempted /fixboot and /rebuildbcd from the default x:/sources directory. Fixboot went fine, but RebuildBCD went:
That sounds like a problem, but I can still boot into windows so long as D: is plugged in externally.
Total identified Windows installations: 1
Add installation to boot list?: Yes
The requested system device cannot be found.
I did get a bsod upon reboot from recovery, with error 0xc0000001, but it didn't come back after a restart.
I was able to back up a system image to the D: drive with it plugged in as an external. I guess it's time to reinstall the system from 8.0 and see if the problem stays behind? I've never done a "Refresh Windows" before, any idea if that would possibly fix any boot problems or should I just do a complete wipe of the C: drive?
