GParted: Partition Manager (editor) for creating, reorganizing, and deleting disk partitions.

A disk device can be subdivided into one or more partitions. The GParted application enables you to change the partition organization on a disk device while preserving the contents of the partitions.

With GParted you can accomplish the following tasks:

• Create a partition table on a disk device.
• Enable and disable partition flags such as boot and hidden.
• Perform actions with partitions such as:
  • create or delete
  • resize or move
  • check
  • label
  • copy and paste

Gparted is a GTK (Gnome)-based partition manager that can also be used with KDE.

• This utility works best as a LiveCD. Download the Gparted .ISO image here. Burn the .ISO image to CD. Use the GParted LiveCD as your partition manager.
• You can also install the package:

sudo apt-get install gparted
