Is there a succinct step-by-step to install/update everything involved in the UEFI boot process? The Handbook appears to have very little on UEFI booting… The UEFI man page has a good explanation of which files are involved in booting: https://www.freebsd.org/cgi/man.cgi?query=uefi&sektion=8&manpath=freebsd-release-ports I mounted the ESP and copied /boot/boot1.efi to /boot/efi/EFI/BOOT/BOOTX64.EFI. Surprisingly, the new boot1.efi is much smaller than what I had before (according to the timestamp from November), but using that, booting seems to be restored. # grep efi /etc/fstab /dev/ada0p2 /boot/efi msdos rw,noauto 0 0 # mount /boot/efi # ls -l /boot/efi/EFI/BOOT/BOOTX64.EFI /boot/efi/EFI/BOOT/bak/BOOTX64.EFI -rwxr-xr-x 1 root wheel 81920 Jan 11 18:43 /boot/efi/EFI/BOOT/BOOTX64.EFI* -rwxr-xr-x 1 root wheel 410112 Nov 25 16:27 /boot/efi/EFI/BOOT/bak/BOOTX64.EFI* Thanks, Stefan -- Stefan Bethke <stb@lassitu.de> Fon +49 151 14070811
