Try to do:
sudo dd if=/full_way_to_backbox.iso of=/full_way_to_usbDevice
Before this You must know a name of usb device.
For it do command "df -h" and find usb Flash.
My command for writing iso looks like as:
sudo dd if=/home/user/Downloads/backbox5.iso of=/dev/sdb
and wait for writing.
Sorry for bad English.
