I played with UEFI Boot for almost a week and couldn't get anywhere with
it. I could get Grub Loaded, and and I could get grub to find the
Kernel, but then it would ALWAYS fail at some memory point during the
Kernel load, and I played and played with the kernel for that week and
it keep freezing at the same point.
The thing with UEFI Boot is you don't need Grub to boot if you don't
want to. If you have a Linux only or Windows only, computer you can
actually boot with out user input without a bootloader. From my
understanding though if you have a dualboot system you need at a minimum
a boot manager to boot without user intervention. If you don't mind
typing a few commands you can boot with out a boot manager or bootloader
in a dual boot system, you just have to understand the UEFI Shell you get.
