# First install grub on the usb, for example:
#
#   $ sudo grub-install --no-floppy --force --root-directory=/media/E310-C779 /dev/sdc1

# Get some of the isos you want to boot
#
#   $ ls
#   boot/
#   ubuntu-12.04.1-server-amd64.iso
#   ubuntu-12.04-desktop-amd64.iso
#   ubuntu-12.04-desktop-i386.iso
#   ubuntu-12.10-desktop-amd64.iso
#   zentyal-2.2-2-amd64.iso
