Creating a Bootable USB Drive from an ISO Image
From a computer running Groovix 2013 or later
Use the groovix-usb-creator program available from the ctrl-alt-g Groovix admin menu.
When creating several bootable usb drives in a row, you may find it faster to use the command line version:
usage: /usr/bin/groovix-usb-creator [ --help ] [ --gui ] --iso /tmp/groovix.iso --dev /dev/sdx
