Dear calling_u3
The udevstart problem is solved because of your advice

Now I have successfully installed all the modules of lfs-6.2
My lfs partition is /dev/hda5
on grub promt I issued the following

grub>root (hd0,4)

setup (hd0,4)
quit
But when I rebooted the system from lfs-6.2 the following result appear

filesystem type unknown partition type 0xb

kernel /boot/lfskernel-2.6.16.27 root=/dev/hda5
cannot mount the selected partition
press any key to continue

On the LFS root I issue the following
root/:df -k ---> result the following

Filesystem 1K-blocks Used Available Use% Mounted on
/dev/hda5 7060276 2875972 3825656 43% /
none 128124 0 128124 0% /dev/shm

none 128124 0 128124 0% /dev/shm
none 128124 0 128124 0% /dev/shm

root/:fdisk -l result in the following
