For gpart, you should specify the base device, i.e. nvd0. The "-i 1" option indicates the partition. In any case, assuming FreeBSD 13 or later, you can just mount the EFI partition and copy loader.efi over: mount -t msdosfs /dev/nvd0p1 /mnt cp /mnt/efi/boot/bootx64.efi /mnt/efi/boot/bootx64.old cp /boot/loader.efi /mnt/efi/boot/bootx64.efi That way you could also revert to bootx64.old if things go wrong. -Dimitry [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.2 iF0EARECAB0WIQR6tGLSzjX8bUI5T82wXqMKLiCWowUCYtLkrQAKCRCwXqMKLiCW o32cAKCxPFRZPdq3d5wWwphp317Az3xQEwCgh8ScImrq+0405UZXWg8ckIdOT2M= =1dlt -----END PGP SIGNATURE-----help
