Within chroot, LFS finds your harddrives by looking into the /dev 
directory which should be mounted before you enter the chroot 
environment (See chapter 6.2).
Can you see your harddrives (hda1, hda2, hda3) inside the /dev directory 
when you are inside chroot?
If not, this should be solved first.

If you have a modern system which uses SATA, your harddrives are usually 
listed as sda1, sda2 etc.
I'm not sure if grub needs different commands in that case.
