Problem with section 8.4.3 of LFS 6.6 book (Testing the Grub configuration)

Dear all,

When I try and test the Grub configuration in section 8.4.3 of LFS 6.6 I get the output below:

root:/tmp# /sbin/reboot
WARNING: could not determine runlevel - doing soft reboot
(it's better to use shutdown instead of reboot from the command line)
shutdown: timeout opening/writing control channel /dev/initctl
init: timeout opening/writing control channel /dev/initctl
root:/tmp# ...
bash: ...: command not found
root:/tmp# grub> root (hd0,1)
bash: syntax error near unexpected token `('
root:/tmp# grub> kernel /boot/grub/core.img
bash: grub: command not found
root:/tmp# grub> boot
bash: grub: command not found
root:/tmp#

This seems fairly serious to me but I have no idea how to proceed.
Help (pointers) would be appreciated. I have searched the threads but have not found anything relevent. Also searched through google to no avail.

My grub.cfg file has 2 entries one normal and one recovery referencing the correct partition for the LFS system. This file looks ok.

Thanks

Hello,
I got same error when installing lfs on my host system. I recommend you instead of using lfs grub boot loader,
use your host system grub loader. with the root account edit /boot/grub/menu.lst and add the following lines:
(I assume your lfs partition name is /dev/sda7 so the grub name of partition is (hd0,6) ):

title GNU/Linux LFS 6.6
root (hd0,6)
kernel /boot/vmlinuz-2.6.32.8-lfs-6.6 root=/dev/sda7 ro
