I am trying to install Ubuntu 14.04 with ASRock hardware. ASRock BIOS has "Secure boot" disabled, and "Fast boot" is disabled too. I have also set the correct boot order in the BIOS.
When trying to boot from Live USB media, I get:
Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press a key
How can I boot a live usb media?
