Unfortunately this does not change the behavior :(. I believe I added
this on later in testing just to see what would happen, if anything.
Thanks, Jacob.
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.
I've changed grub-install to add the --modules flag, so it's now ran as
grub-install --target=x86_64-efi --efi-directory=/boot/efi
--bootloader-id=LFS --modules=part_gpt --recheck --debug
Here is my grub.cfg, although it attempted to boot into blind mode
without loading efi_gop and efi_uga. I believe the grub configuration is
irrelevant because I can chainload off my arch linux install, and still
come to the same issue.
# Begin /boot/grub/grub.cfg
set default=0
set timeout=5
insmod ext2
set root=(hd0,gpt2)
#insmod efi_gop
#insmod efi_uga
insmod font
if loadfont /grub/unicode.pf2; then
loadfont /grub/unicode.pf2
set gfxmode=auto
insmod gfxterm
set gfxpayload=keep
terminal_output gfxterm
fi
menuentry "GNU/Linux, Linux From Scratch" {
linux /boot/vmlinuz-4.7.2-lfs-7.10-systemd
root=UUID=d6788259-f948-4164-ae29-d1b996ffd6d9 rootfstype=ext4 ro
}
I will backup my .config, and attempt to compile with an arch linux
kernel .config to see if there's any config I'm missing.
Thanks, Jacob.
