    Question Can't boot to cd with UEFI on?

    I can't seem to press F12 to boot while UEFI is enabled. SecureBoot is disabled, the option to use F12 is enabled, but it doesn't work. Unless I disable UEFI. Trying to install Ubuntu 13.04.

    Every vendor seems to do UEFI a bit different even thought it supposed to be a standard.

    I would try a flash drive.

    A few systems have to install in BIOS mode and then use Boot-Repair to convert to UEFI.

    What system it this? And what video card/chip?

    Besure to review install instuctions for UEFI. See links in link in my signature.

    In Windows, make sure "fast boot" is disabled. You then get more time to type function keys at bootup. Without fast boot, 6 seconds to vendor splash screen, then I type F12 and it works. With fast boot, splash screen come up in 3 seconds, but then F12 doesn't work. Repeatedly typeing F12 right after power-up may work half the time.
