Enabling systemd debug protocol entries during boot contains an additional entry in /boot/grub2/grub.cfg.

If not already mounted, mount the efi partition.

fdisk -l | grep "EFI System"
/dev/sda3  10240    30719    20480  10M EFI System
mkdir -p /boot/efi
mount /dev/sda3 /boot/efi

Edit the /boot/grub2/grub.cfg file. In Command line beginning with init=/lib/systemd/systemd add systemd.debug-shell=1 systemd.log_level=debug.

To view the boot journal, run journalctl -k.
