After an installworld on my box I would usually do: # mount -t msdosfs /dev/ada0p1 /mnt/ # cp /boot/loader.efi /mnt/EFI/freebsd/loader.efi # umount /mnt To update the EFI loader. You might have to check the output of `efibootmgr -v`to make sure you are replacing the correct loader. I guess there must also be a way to do this with efibootmgr. Roger.help
