Introduction
A live image is a safe and easy way to test the Fedora operating system on your own familiar hardware. If you enjoy this experience, you can install the live system software to your system's hard drive. The installation can either replace your existing operating system, or co-exist separately on your hard drive. This live image provides you with an experience that is very similar to running Fedora, but there are some important differences. Refer to link titlefor more information.
