Have a look at the info above....
Google "how to create bootable usb drive" for help (other search engines are available..)
Google "how to set bios to boot from a usb drive" for help
You might want to Google "partitioning your hard drive for ubuntu" or "dual boot Ubuntu" for some info before installing. Until then use the live distro to find your way round.
Have fun it is a great distro for beginners
