Partitioning your hard drives is rarely a fun business and oftentimes can be a real pain to do. Thankfully, it's a lot easier than it used to be to slice up and mess around with your drive, which is only helped by the fact that nowadays we have graphical applications for this sort of task.
The GParted Live CD is designed to allow you to have a bootable system with graphical partitioning tool GParted pre-installed and ready to use. If you're planning to do a reorganisation of your system any time soon, it may well be worth downloading and burning a copy of this CD for when you get to the partitioning stage.
GParted can come in handy for everyone, not just Linux users as it is able to see and deal with Windows partitions too. The Live CD includes the NTFS 3G driver for reading and writing to Windows partitions.
The GParted Live CD is free, based on Gentoo Linux and available from the GParted website.
