I have the fix for this! Not sure if you've already seen it in my thread you responded to earlier, but here's how to fix this.
Download EFI Mounter, select the correct disk (it will tell you what number your system disk is, so just match the first digit from the list) and mount the EFI partition. Open it up, and go to EFI/CLOVER/drivers64UEFI folder, remove the OsxAptioFix2Drv-64.efi (some users might have OsxAptioFixDrv-64.efi), and replace it with the OsxAptioFix2Drv-free2000.efi file from this link:

I just tried this and it seemed to solve the issue.

Disabling the onboard graphics in bios fixed this immediately for me.
Dang, well that might be the fix I've been looking for all this time! The "solution" that I proposed earlier ended up not working for me in the long run, but digging into the BIOS confirmed that sure enough, my integrated graphics had been re-enabled at some point. So strange that it causes inconsistent boot-ups.
Anyway, THANKS! Done a couple reboots with zero problems so far.

Work for me too. I additionally replaced VBoxHfs.efi with HFSPlus.efi in EFI/CLOVER/drivers64UEFI/
this worked for me too.The free2000 one resolved this for me, too - MSI Z170A Gaming M5
