You were very right since it died again; this time confusing C: and D: (old Windows), even when D: was formatted windows (stupidly) keeps the BCD sector there and again stupidly it corrupts the nice fresh boot sector on C:
The BCD fix commands didn't work due to access problems. I was lucky to fix it by switching to Windows 8/10 WHQL in BIOS and reconnecting the D: I had disconnected and bunch of BCD fix commands through the prompt.
When the C: booted nicely, I went ahead and deleted the secondary boot on D: using msconfig. Now it boots fine with D: hooked up. But my confidence that it won't mess up again is around 10-15% level. So I got a system image, which raised my confidence to 30-40%. Still not even half since Windows is excellent in finding excuses to not to recover/restore. I have Macrium installed already so I'll take your advise and see if I can raise my confidence level more than half. This time I keep almost nothing in C: for safety reasons: in fact I am using my smallest (200GB) SSD for C: to force myself not to keep anything there lol.
