dual boot with Kubuntu

[mtu1492]

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.
