I must have just missed it be cause that has to be what happened. I tried sfc first, stuck art 37% 2X.
But I did not have the W10 pro dvd loaded.
Then in Safe mode, using sfc in admin prompt with the win 10 dvd in it went to 100% and all was well.
I know I shouldn't care why. but I kind of like to know if it was something I did. I guess I will never know.
when I first got the dreaded message and went into the continuous reboot loop I tried the Gpart usb drive I made.
It is an amazing tool. When I looked at the physical drives they checked out as fine. That immediately gave me hope.
Because I had thought that the new (well new to me) Samsung Evo 850 ssd OS drive had died.
Also did a virus scan with Gpart ...just a great tool.....
Oh well, So I will never know......................I have backups, images, etc, in multitude but couldn't be sure what it was.
