GParted Live is a business card-size live CD distribution with a single purpose - to provide tools for partitioning hard disks in an intuitive, graphical environment. The distribution uses X.Org, the light-weight Fluxbox window manager, and the latest 4.x Linux kernel. GParted Live runs on most x86 machines with a Pentium II or better.
