"No administrator was found" in Startup Security Utility

by Hadi   Last Updated July 11, 2019 19:12 PM

My friend got a new MacBook Pro from office, later on he resigned and in a hurry erased the "Macintosh HD", now we are trying to install Mojave using Bootable USB but it won't allow because "External Boot" is not allowed, also when we try to access "Startup Security Utility" it shows an error saying no administrator was found, so we can't enable "Allow booting from external media". Somehow online installation from recovery mode is also not working and throws 202 error at the end. Is there any luck?
