I assume that ubuntu set grub to boot from a boot sector on hda1. If you can find that feature, re-install Ubuntu to the external just like before, but watch for the window that asks you where to install GRUB. So if it is shutdown and reboot, then this next time instead of selecting boot windows, choose fix windows, and you can probably figure it out form there I forgot the I am not familiar with GRUB commands.
