Good info here, Tony.

*If* it is successful and at the recovery mode of any of the lucid 
kernels, say 2.6.32-21 or 2.6.32-22, the commands do not give unusual or 
error feedback.

Then reboot again but without the 'single' , as an example...

root   (hd0,7)
kernel /vmlinuz-2.6.32-21-generic root=/dev/sda8 ro
initrd /initrd.img-2.6.32-21-generic
boot


note: the kernel line, remove the 'single' (you can try 
vmlinuz-2.6.32-22) - should work then.

Then you should be able to boot to the lucid properly using (manual) 
grub-legacy commands. Since lucid uses grub2 instead, you should install
grub2 by "sudo apt-get install grub-pc" , (there have been some changes 
and if this command doesn't work, use "sudo apt-get install grub2")

Proceed to full installation of grub2 by following the instructions 
carefully, there is a need to issue a command, (memory a bit rusty..I 
think it's convert to something...besides chainload from legacy). Please 
make sure you do the "convert something" command.

Then we're home.

Good luck again. - Goh Lip
