I still don't understand how you are not getting any output.
Can you list all the files you have under /boot/efi
This is what I have:
/boot/efi/EFI
/boot/efi/EFI/Boot
/boot/efi/EFI/Boot/bootx64.efi
/boot/efi/EFI/LFS
/boot/efi/EFI/LFS/grubx64.efi
Also, are you able to remove the font/if part (not sure what that does) in your
grub.cfg file?
This is what I have in grub.cfg:
set default=0
set timeout=5
set menu_color_normal=green/black
set menu_color_highlight=light-green/black
insmod ext2
menuentry "GNU/Linux, Linux 4.7.10-lfs-7.10" {
set root=(hd0,3)
linux /boot/vmlinuz-4.7.10-lfs-7.10 root=/dev/sda3 rootfstype=ext4 ro
}
And finaly, how did you execute grub-install?
This is what I do:
mkdir -p /boot/efi
mount /dev/sda1 /boot/efi
grub-install --modules=part_gpt --bootloader-id=LFS /dev/sda
cp /boot/efi/EFI/LFS/grubx64.efi /boot/efi/EFI/Boot/bootx64.efi
and this is my fstab:
/dev/sda3 / ext4 defaults 1 1
/dev/sda2 swap swap pri=1 0 0
/dev/sda1 /boot/efi vfat defaults 1 2
Regards,
Wayne.
