I have a 32GB USB drive with 2 partitions:
Partition 1: FAT32 used as storage, since Windows only sees the 1st partition of a USB drive
Partition 2: 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 have access to a second 512MB USB drive in order to run e.g. DamnSmallLinux, GParted or some other small Linux distro that could fit in. I'm running Windows7 with Cygwin on desktop PC and OS X Yosemite on laptop.
