For 12.04.3, I can also successfully boot using the steps above, along with feeding the correct commands to grub at the grub prompt. The only difference is that I have to apply the patches to partman-base, partman-utils, and efibootmgr. Those fixes are in 13.04 and above, but, not in precise (yet).
