[Solved] - Tower's 1st [no, 3rd] Hard-Reset since clean-reinstall.

So you can boot this machine via the USB live media an get a display (GUI), but not on the installed system?
Then this is definitely not a UEFI issue, but a driver issue. I will look at your log file and see if I can find the issue.
NOTE: You may need to fix this from the Live media using a chroot.
