I have followed the instructions for creating a bootable usb drive on my mac for use on another non-mac machine. The non-mac machine is not booting off the new usb drive. I notice that in the instructions here (http://www.ubuntu.com/download/desktop/create-a-usb-stick-on-mac-osx) it mentions that macs tend to append the .dmg suffix to *.iso.
If that happens -does anything need to be done? The sudo dd commands seemed to work. I am trying to determine if I created a good bootable usb drive or if my problem lies elsewhere.
