I have an older laptop on which I have been running the current version (I think) of Ubuntu for a few months. I now would like to install Ubuntu Studio, so I made a bootable USB for it.
When I shut down my computer and turned it back on, it booted like normal, not even noticing the bootable USB plugged in. I'm fairly certain the USB should work, since it appears on my desktop, and the USB has all the right stuff on it.
How can I boot from my LiveUSB?
Additional Info: My computer is a Compaq Presario cq60, with Nvidia graphics and sempron AMD (which I believe is a soundcard). It originally ran Windows Vista.
