I hope this is appropriate thread to ask.

Is it possible to install Ubuntu on Macbook (I have 2,1 Macbook, I think, 2.1Core2Duo, Intel, black, 1G RAM, bought in summer 2007) without installing OS X?

As far as I figured out, EFI partition is something that must exist, but still don't get all things.

Thank You in advance for any kind of answer.
