I found all the favorable comment about CloneZilla on the web while looking for a way to clone a new Ubuntu Koala grub2/ext4 install. The current version of CloneZilla with the Koala kernel did indeed work. One error message appeared in the section about reinstalling grub2:

chroot: cannot run command '/grub2-sh-RSkJuV': Exec format error

However, the newly cloned drive did boot up (after I reset the harddrive boot order in BIOS). Is this error something that I need to fix?

Many thanks for a GREAT LiveCD!
