You actually might not need a bootloader with an efi system. As "In late 2011, Linux kernel developers began work on a new way to boot Linux on EFI-based systems. This approach turns the Linux kernel into an EFI application. Once loaded, the kernel takes over the computer, effectively bypassing the need for a boot loader in the strictest sense. This approach has its own unique advantages and disadvantages, as detailed on this page. (If you're interested in the technical details, you can read about them in the Linux Kernel Mailing List thread on this topic.)"

Rod Smith has a ton of information on efi, you'll find what I quote above here

I have booted kernels directly from the efi firmware on my Asus G751JM without ant bootmanager/loader. I don't see why it shouldn't work for you, unless your efi firmware is particularly limited

Ubuntututu because of the naming convention and fstab grub thing, if it uses UUID then you're in like flint. which by now I bet that it is default install .. the only Linux I know that still creates its fstab

is Slackware.
