It's been over 2 hours and nothing, just a black screen.
I fear I have no alternative except to power off and restart
it. First, I want to see if #3 is still OK and boots correctly to
the desktop, aside from the normal messages of abnormal
shutdown.

If it does, then I can try the F8 again and see if it does what it's
suppose to so I can finish this process. See what I mean? the
same way when we were attempting to clone the1TB for the first
time ever and it gave us that Invalid Windows OS. Which put us
in this situation after we had already done all that previous work.
