Trying to upgrade from Window 8.1 to 10 using an ISO when the setup fails when trying to reboot with the error "Something Happened - Windows 10 installation failed".

I have uploaded my error log and setup logs as follows https://www.dropbox.com/s/aeg9o8hsm9wcmep/setuperr.log?dl=0 and https://www.dropbox.com/s/9mnei676op1yj1x/setupact.log?dl=0.  The tail end of my error log is pasted below.
