I can help you with that but first paste your output from cfdisk
so we will know what partitions you are using.

for the mean time i can give you some example, its better you read the grub
manual because its all there.

this is my cfdisk sample output

hda1                    Primary   Linux swap / Solaris              1003.49
hda2        Boot        Primary   Linux ext3                       10001.95

this is my /boot/grub/menu.lst

# Begin /boot/grub/menu.lst

# By default boot the first menu entry.
default 0

# Allow 30 seconds before booting the default.
timeout 30

# Use prettier colors.
color green/black light-green/black

# The first entry is for LFS.
title LFS 6.1.1
root (hd0,1)
kernel /boot/lfskernel-2.6.11.12 root=/dev/hda2

this is my /etc/fstab

# Begin /etc/fstab

# file system  mount-point  type   options         dump  fsck
#                                                        order

/dev/hda2      /            ext3   defaults        1     1
/dev/hda1      swap         swap   pri=1           0     0
proc           /proc        proc   defaults        0     0
sysfs          /sys         sysfs  defaults        0     0
devpts         /dev/pts     devpts gid=4,mode=620  0     0
shm            /dev/shm     tmpfs  defaults        0     0
# End /etc/fstab

this is my sample grub session

grub> root (hd0,1)
Filesystem type is ext2fs, partition type 0x83

grub> setup (hd0)
Checking if "/boot/grub/stage1" exists... yes
Checking if "/boot/grub/stage2" exists... yes
Checking if "/boot/grub/e2fs_stage1_5" exists... yes
Running "embed /boot/grub/e2fs_stage1_5 (hd0)"...  16 sectors are embedded.
succeeded
Running "install /boot/grub/stage1 (hd0) (hd0)1+16 p
(hd0,1)/boot/grub/stage2
/boot/grub/menu.lst"... succeeded
Done.

Hi everyone!

 I m using LFS 6.0
- I have reached to chapter 8. My kernel installation
is complete. Now I m trying to   make my lfs sys
bootable.

-For this when I run command ‘root (hd0,2)’ on grub
prompt it shows error msg ‘specified device does not
exist’.

-Even when I use TAB for command completion, it does
not list out my hard drive. (Shows only - fd0,cd)

-When I try to mount any of the hard drive partition
on chrooted environment it shows     ‘device does not
exist’.Nor does it lists any of the partition as
output of  ‘fdisk –l’ cmd.

-at the same time, when I tried same commands on host
sys,they run well.
  Like- ‘ root (‘ <TAB>   detects hard drive.
        ‘fdisk –l’        shows all hard drive
partitions


What the problem could be.
Please help.
