Ubuntu's grub2 is already automatically using UUID to boot and there is 
no problem with external drives. There is no need to manually specify or 
add in the external drives in the grub.cfg. If it is not there, just 
make sure the external is plugged in and at terminal, "sudo 
update-grub". This should add in the external drive at the grub menu.

But since you asked about using Label to boot, the following works too.


search --no-floppy --label --set=root xxx
linux /boot/vmlinuz-2.6.3x-xx-generic root=LABEL=xxx ro
initrd /boot/initrd.img-2.6.3x-xx-generic
