Just copying the file to the USB is not enough - you need to use a program called UNetbootin to create a bootable USB drive

(That is, if you're on Windows or MacOSX)

If you run Ubuntu, use Startup Disk Creator which is installed by default:

See this article for more details

you might want to run "startup disk creator" or burn the image to your USB pen drive.

keep in mind that a simple copy of the iso file you've just downloaded wont work at all.
