As muru has mentioned, you need make it possible for the world repos to instaIl téstdisk in Ubuntu. Even so, I would recommend using one of the Live Save CDs listed alternatively, instead of an Ubuntu cd/usb. They're in essence Linux distros that include a ton of data recovery/repair programs mounted, including testdisk. The advantage of that is that you have a ton of applications dedicated to data recovery all in one place, but more importantly, many of them are configured never to touch the HDD during boot. When you're doing data recovery, the more you gain access to/modify the data on the push, the not as likely you can recover files. Ubuntu accesses the hard disk drive quite a bit during boot, even though utilizing a live compact disk/usb, which makes it not quite ideal for data recovery functions.
