GParted Live lets Windows users take advantage of the powerful features of the Linux-based GNOME Partition Editor, aka GParted. It runs at boot, so you must unzip the software's ISO file and burn it to CD (or similar discs) to use it. You don't need to know Linux to use GParted Live, thanks to its graphical interface, extensive manuals, and the sort of support only available with open-source freeware.
Powerful: You must boot from a CD or similar source to manage your main drive or other drives Windows needs when running. GParted Live's graphical interface makes the process seem more familiar.
USB, HDD: GParted Live can be installed and run from a CD or similar optical discs, but it can also run from a USB drive, PXE server, or hard disk (with helper apps). Instructions for each (and creating GParted apps from scratch, too) are available online.
Manuals and more: The GParted home site offers many resources, including installation and usage manuals, lists of available boot parameters, forums, and guides to included graphical and command-line utilities.
Backup: Take a full backup capable of completely restoring your computer before using GParted Live on your main hard drive. No excuses!
Dangerous: In inexperienced hands, GParted Live can do serious harm (see above).
GParted Live puts powerful capabilities at the advanced user's fingertips. Users unfamiliar with managing disc partitions or booting outside Windows should start with one of the excellent freeware partition managers for Windows-based computers.
