On the GhostBSD live session, you can mount the efi partition and create a ghostbsd folder.
âšī¸ NOTE
Replace * by the appropriate number.
sudo mkdir /mnt/efi
sudo mount -t msdosfs /dev/ada*p* /mtn/efi
sudo mkdir /mnt/efi/ghostbsd
sudo cp /boot/loader.efi /mnt/efi/EFI/ghostbsd/BOOTX64.EFI"
Once this is done, you clean and create the EFI.
Look if GhostBSD already exists:
sudo efibootmgr
If so, remove it:
sudo efibootmgr -B -b Boot000*
Now, you can create the GhostBSD entry:
sudo efibootmgr -c -l /mnt/efi/EFI/ghostbsd/BOOTX64.EFI -L GhostBSD
To active it:
efibootmgr -a -b Boot000*
To set it to boot as default:
efibootmgr -n -b Boot000*
