Just a few things I'd like to ask.
1. When I went to disconnect the two sata drives, is it normal for the two drives to be connected like that? Please see the photo in post #42. I expected them to be two separate cables going into each drive. But it's actually connected. Maybe it's normal? Anyway, I just unplugged the power cable from each, as them wider ones would not budge and I was afraid of damaging them.
2. Once I reached the desktop in the clean install I had to power off as I had to head away from the PC.
Will it be OK to just power on again and resume trying yo connect to the Internet to do all of the usual Windows updates? Or, are they strictly meant to be done without having shut down my PC?
If its the latter, I can easily just boot again from the USB and start it again, it didn't take long to reach the desktop.
