However, that process will leave the installed version of Kubuntu in BIOS emulation mode. It will not boot into UEFI mode.
Most of the kernels in the 3.8 series have a problem in which they refuse to add UEFI NVRAM variables if the available space is reported to be less than 50%. This is to work around a serious bug in certain implementations that completely break some Samsung laptops.

As you can tell by reading bug 1167622, commit 68d929862e29a8b52a7f2f2f86a0600423b093cd is the cause of the problem. Kernels built with this commit reverted (http://kernel.ubuntu.com/~jsalisbury/lp1173423/) work fine.
Commit 31ff2f20d9003e74991d135f56e503fe776c127c is an attempt to get smarter about the 50% space issue. But kernels containing this commit (http://people.canonical.com/~jsalisbury/lp1173423/) are still failing.
Unfortunately, until this gets fixed in the kernel and the ISOs are updated to include a fixed kernel, UEFI installs are going to break. We have many reports of this on the Kubuntu forum.
