SFC unable to fix problem

... have posted results prior ...

I assume you mean the SFC results extract posted by zbook in his post #14.
I do not know anything about what zbook asked you to post. I had no idea that it included SFC results.

I can find no trace of avast anywhere on the computer

This is a shot in the dark but did you make use of any Avast icons by allocating them as the icons for shortcuts that you created to any Windows components such as Disk management?
I've seen reports of that causing irreparable SFC errors before. @Farvatten

Personally, I'd try a Repair install in your situation but only because I could not think of anything more logical to do.
Despite its name, it is a repair operation not an installation.

You can't update your BIOS without the right USB-Flashdrive.

The autoexec, Efiflash, and the Z370HD3.F14 bin files are there and will be needed on the FLASH-Drive.
Don't do it, if you don't know how!

It is even possible that the step from F3 to F14 is to big and an intermediate step is needed.
F3 > F? > F14
