In general, if you have EFI partition on your disk, u can use it to store boot loaders. If u can boot FreeBSD in any way, u can check there : gpart show Then mount_msdosfs /dev/adaXpY /anywhere your EFI partition. Next you do mkdir -p /yourEFImountpoint/EFI/freebsd cp /boot/loader.efi /yourEFImountpoint/EFI/freebsd/ Next part is adding your FreeBSD boot loader to your Bios. efibootmgr -c -L FreeBSD -l /yourEFImountpoint/EFI/freebsd/loader.efi Reboot system, and hit F12(or any other key) to select boot option You should see FreeBSD there. > On 7 Sep 2020, at 03:47, Kevin Oberman <rkoberman@gmail.com> wrote: > > I know it's possible, because I did it once by accident.
