I apologize for the horribly worded title, but it's all I could think of. Anyway, I have a MacBook Pro and I've followed the instructions here: http://www.ubuntu.com/download/desktop/create-a-usb-stick-on-mac-osx
I current have Ubuntu up and running with the trial edition or something (I apologize again for my horrible terminology), just not the full install. I have a "Install Ubuntu 12.04.2 LTS" on my desktop, but I have hesitated to click it because I do not want it to install on my hard drive. That would be a disaster. Anyway, my question is this: will that file install the full Ubuntu on my flash drive only, or on my hard drive? Thanks a bunch in advance!
