/etc/grub.d/40_custom of the host, then ran update-grub menuentry
"LFS 7.6 on sda7" { insmod ext2 set root='(hd0,7)' echo 'Chargement

echo 'Chargement de Linux LFS...' }
As far as I understand your setup you should keep:
insmod part_gpt
and the "linux" line should be:
linux /vmlinuz-3.16.2-lfs-7.6 root=/dev/sda8 ro
But that does not explain the error you see.
You may be missing some switches in the kernel config, concerning either
your disk hardware (with standard ATA disks, you need to enable several
switches in "Serial ATA and Parallel ATA drivers"), or the GPT partition
scheme (you need "EFI GUID partition support", maybe the first thing to
check).

The "linux" line should be: linux /vmlinuz-3.16.2-lfs-7.6
root=/dev/sda*7* ro since it's the boot partition, sda8 is /
For linux, "root" is '/', and, since '/' is on /dev/sda8, I confirm that
the linux line should have "root=/dev/sda8". The boot partition is only
"root" for grub. Hence the "root=(hd0,7)" in the grub commands.
