I have an Intel NUC 10 i5 with 256 gb ssd. I tried using an external ssd because I thought It may be because of the M.2 ssd port. All the bios setting I verified twice. Here is the EFI Folder I was able to boot into Catalina successfully and everything worked excluding WIFI of course. Problem is when trying to update to Big Sur I already updated all the kexts and drivers to open core 0.6.0 so I believe that shouldn't be the problem
