    dual boot with Kubuntu

    I have an external hdd and want to install Kubuntu 13.04, I seem to be having issues with the UEFI, a screen comes up for just about 3 secs. I'm looking for suggestions on the fix. I have a Gateway 64-bit with Windows 8 pre loaded.

    Ubuntu and opensuse work fine with secure boot. Not sure about kubuntu, the site says:

    Kubuntu should now be able to support UEFI Secure Boot, a standard for controlling what software can be run on a computer. Supporting Secure Boot, a part of the Windows 8 certification requirements for client systems, ensures that Ubuntu will continue to provide an "it just works" experience on new hardware.

    If you have hardware for this, we would appreciate your help in testing it out.
    Perhaps worth asking at Kubuntu forum. They would enjoy your feedback.

    Enabling the F12 function:

    1.Power on the system. As soon as the first logo screen appears, immediately press the F2 key, or the DEL key if you have a desktop, to enter the BIOS.
    2.Press the right arrow key to select Main.
    3.Use the arrow keys to navigate to F12 Boot Menu, and press ENTER.
    4.Select Enabled, and press ENTER.
    5.Press the F10 key to save changes and restart the system.

    Bootable media from previous versions of Windows may not be recognized in Windows 8. You can change the Secure Boot setting and it should recognize the bootable device.

    Use the following steps to change Secure Boot:

    1.Completely shut down your computer.
    2.Power on the system. As soon as the first logo screen appears, immediately press Delete to enter the BIOS.
    3.Use the right arrow key to select Authentication.
    4.With Secure Boot highlighted, press Enter and then the down arrow to select Disabled.
    5.Use the right arrow key to select Boot Options.
    6.With Launch CSM highlighted, press Enter and use the down arrow to select Always.
    7.Press Enter.
    8.Press the F10 key to save changes and restart the system
