Tuxboot, a bootable USB drive for Clonezilla, DRBL Live, GParted Live and Tux2Live, is a lifesaver. I cannot recommend it enough. I got a new, 3x bigger drive for my laptop and cloned it with Tuxboot/Clonezilla and resized the primary partition with Tuxboot/GParted. All went without a hitch. I love free things that work.
