[all variants] Single boot EFI?

Hi everyone,

I have a mid 2012 macbook air that I'd like to install Ubuntu on. I would look to boot through EFI and not the legacy bios, and I would like it to be a single boot installation (ie no Refit or dual booting).

I've been looking all over the internet and I haven't really found a solution, does anyone have a similar setup that can shed some light on this?

Thanks!
