With RL8.3 on EFI machines, one needed to call grub2-mkconfig as the last step of the migration, before rebooting. See: [SOLVED] Grub prompt after CentOS 8 -> RL8 migration - #2 by knight-of-ni
Can anyone confirm whether this has been fixed in RL8.4?
For now, I’ll keep issuing grub2-mkconfig --output=/boot/efi/EFI/rocky/grub.cfg just in case.
