It is an option in your bios, not the installer. Typically there is an option in the bios setup to disable EFI mode or use Legacy mode, or if you press a key ( typically F9 ) to choose to boot from the usb instead of the hard drive, there are usually two entries: one that says Ubuntu, and one that says the name of the USB stick. The latter is bios mode.
