Linux Mint preinstalls a backup solution, Timeshift, which can make a complete system backup (if you also include your home folder) on the same drive. You can then restore the backup from the USB install medium. I have used that a few time already to restore the system to an earlier state. It works like a charm. So, as long as you make a backup before, go ahead, destroy your system :-)
