I'm trying to install ubuntu 13.04 to a 32gb usb stick so I can bring It to and from school. I've install about three time now using the something else install method And every time I install it says something like this "Installation complete please restart your computer". When i restart the computer and hold down alt (Due to the fact that I'm on mac) The usb doesn't show up as a bootable thing. When i go to reinstall it to the usb useing a cd it says that it is installed on it. So I want to know how to fix this
NOTE (I don't want the iso on the usb thats on the cd. I want the os on the USB so i can bring to and from school)
computer specs for home and school they are macs
if they were pc this would be SOOO much easier saying how I've installed it on pc before but not mac and a usb together
