[CentOS] Need help transfering CentOS5 from desktop to laptop

created 2 partitions on laptop (/ and swap)
formatted them.
mounted both source and target (under /mnt on each machine)
rsync -a / from desktop -> laptop
(Note: OS on desktop is on sdb5. On laptop it's going to sda1)

Now I need to put grub on mbr of laptop
boot: linux rescue
chroot /mnt/sysimage

Here is my problem

grub-install /dev/sda
The file /boot/grub/stage1 not read correctly.

Can anyone determine why I'm getting the above error?

I also tried
cp -a /usr/share/grub/i386-redhat/*  /boot/grub
no joy

Here is all important info (gathered from linux rescue chroot /mnt/sysimage):
