plutomaniac Thank you! I was not aware of that, and though it all had to be setup correctly no matter what, if one was off/wrong/not set then it couldn't work. I didn't know once FPF set then it's enabled no matter what.

@vdubble05 - due to this, bootguard is enabled, so only certain things within the BIOS may be changed, and BIOS mod would fail in many instances, so not safe for you to test mod BIOS without a programmer and SOIC8 test clip cable in hand to recover if needed.
Often I've seen grub settings change be OK though, so if you can get that working you'll be able to make some changes.
