You can download the Linux Mint operating system for free. It comes as an ISO file
which you need to burn to a blank DVD. The liveDVD is then bootable and provides a
fully-functional operating system which you can try without affecting your PC. In
layman's terms, when you put Linux Mint on a DVD and place it into your computer, you
can try it out while leaving your current system intact.
Note: It is also possible to write the ISO image to a USB stick or other memory device and boot from that,
or to boot from the ISO image on the hard drive, but these options are somewhat more advanced and the
method presented here is recommended. For help with alternative methods of installing and running Linux
Mint, please visit the forums
