No "Problem Reporting" files attached.
Read FAQ, "Problem Reporting" again. Carefully. Attach all requested files/output.

Use the gen_debug.sh tool mentioned in the FAQ, that way it is less likely you'll omit something.

Note: Setting DVMT-prealloc as per post #1 is NOT optional.

Thank you for your response.
I installed Windows and it wiped out the macos installation.
I want to start all over again, and this time, performing all the steps as you have nicely detailed.
However, I'm stuck at the first step "use a EFI shell to change the DVMT-prealloc from the shell." (I have the UHD model of Y50)

Full information on setting DVMT-prealloc is in post #1.
If you have a question, you must provide details, not just "I'm stuck".

Thanks RehabMan, your guide had explained everything. I downgraded my BIOS to 1.14 (from 3.03), and did the
setup_var 0x18C 0x4.

Post #969 implies you cannot boot.
Yet, in this PR file set, you provide ioreg, which implies you CAN boot.
Which is it?

Your drivers64UEFI is not per guide.
Read here carefully:
