Found the issue.I had read those instructions on insanelymac, and that was the first thing I tried...
That didn't work for me.
I have no kexts in anything but EFI/Clover/kexts/Other
I even tried with a smaller subset of kexts/efi using the original EFI folder from the USB install disk, didn't change a thing
