That's exactly right. When you're done, remove the old disk and put in the
new one. Boot knoppix, or any other live CD, and mount your partitions at
/mnt. Now chroot to /mnt ("chroot mount").

At this point, your shell thinks it is running on your system with all the
proper paths in place. It's almost like you booted off the new disk.

now just grub-install.sh and you're done.
