I have a 32GB USB drive with 2 partitions,
FAT32 used as storage
ext4 intended to be a bootable live Ubuntu 15.04.
How can I install the Ubuntu ISO file to the
ext4 partition on the USB drive and make it bootable?
I tried booting DamnSmallLinux and DSL-N from another 512MB USB drive I have but couldn't find how to make this work.
I'm running Windows 7 on desktop PC and OS X Yosemite 10.10.4 on laptop.
