I responded in your other thread, about that. Still there is no reason not to just boot from a USB drive.
Download Mint Cinnamon here. I would choose with Codecs.
Use unetbootin to put that ISO on a USB drive, then boot from that USB drive. Or burn the ISO to a DVD, doesn't matter. You can still issue any command you want, you can still install anything you want, just things you install / save won't be actually saved. However you still get to mess around with everything, it's just like be installed, just slightly slower.
