OK, I ran the Post #108 instructions again (KB4048957) and it installed successful. Can I mess anything up by running a fixlog we've already run or by running the SFCFix.zip in Post #165? It seems like I'm at Post #163 at this point. It was after I followed the Post #163 instructions that the next restart had the black screen.
So in-between Post #163 and post #165 the black screen happened so I was not able to do what you provided in Post #165.
