I did read about features making it more difficult to boot non MacOs and non-Windows operating systems in some Macintosh computers. I thought it was only for the touch bar Macbook Pro models but I might be mistaken. If this is what is getting in your way, you should be able to boot into the recovery partition and change a setting to allow other OS’s to boot the computer. I wonder if they somehow make changing this type of security mode password protected. I never played with the protections introduced in High Sierra that prevented root from modifying system files but if there is no protection on security changes that need to be made in recovery mode, than one might as well not have the security settings there in the first place.
