Creating and booting from a Live USB drive can be used as an alternative to the standard approach of burning and booting a Linux CD. This is particularly useful for installing Mint on computers that have trouble booting from CDs, or for those who can't or don't want to burn a CD.
Graphical installation using UNetbootin
Summary
UNetbootin provides a GUI to create Live USB drives from ISO files. To create a Live USB using UNetbootin, download an ISO file, select it under UNetbootin's "diskimage" option, and specify your target USB disk under "Drive:". After pressing OK, wait as the ISO is extracted to your USB drive; once done, you will have a bootable Linux Mint Live USB drive.
