Download Clonezilla ISOÂ at http://clonezilla.org/
You first need to burn the ISO file with a CD/DVD burning software like Roxio Creator 2010 Pro which has an ISO burning feature.
CloneZilla is a free Linux liveCD which users can use to clone their hard drives or partition. What is best about Clonezilla is it does not require you to permanently install it on a hard drive. This saves you time, and it means you can clone your hard drive even if Windows won’t start, so you can at least restore your files to another drive to restore your files. Plus, since Clonezilla is a livecd, it won’t get slowed down by other processes like your antivirus, msn, etc. All your CPU and RAM resources will be used to clone your drive. Clonezilla is best for people who have slower PCs since it does not need a fast CPU or lots of RAM to work. It is also good if you just want to quickly clone your drive without the need to install an additional program to your PC. Clonezilla can also be set up to back up or restore an image to another computer on a network. For most users, imaging and restoring  a computer to an external hard drive like the Iomega Prestige 1 TB USB 2.0 External Hard Drive would be good enough for their needs. The downside of Clonezilla is its appearance is not very nice, and requires more reading then most cloning software made for Windows.
If you want a disk cloning software that works within Windows, and offers a better simpler user interface, Symantec Norton Ghost 15.0 (1 PC) is more suited for your needs.
