Post your grub.cfg file

raza.ajmi · 12-17-2012, 05:26 AM

# Begin /boot/grub/grub.cfg
set default=0
set timeout=5
insmod ext2
set root=(hd0,2)
menuentry "GNU/Linux, Linux 3.5.2-lfs-7.2" {
linux
/boot/vmlinuz-3.5.2-lfs-7.2 root=/dev/sda1 ro
}

When you ran the update-grub command on your host, was LFS mounted? I do believe it should be.

Which grub.cfg is this? I do hope it is not the one on your host.

If you have chosen to use your host to take care of your booting then you do _not_ do 8.4. Using GRUB to Set Up the Boot Process. You either use your host or lfs, not both.

I don't think you understand my previous question: Did you mount $LFS before you ran update-grub?

Did you run update-grub with lfs mounted as druuna mentioned
which partitions are lfs on
