I'm going to describe my problem in full, and then ask the question for the solution that I think I've come up with. If someone has a better different way to do this, that would be much appreciated as well.
I am installing Ubuntu 13.10 onto a Macbook pro 9.2 I have done this twice before, with the caveat being that, when I did this before, I just set up a dual boot. Now, I am trying to setup Ubuntu exclusively, and also trying to encrypt my hard drive. I tried installing Mac OS first, and then setting up a second partition, and creating a refit partition, and then deleting the first partition, but the Ubuntu installer won't let me encrypt my hard drive if I do it that way.
I can get through the installation process just fine, but when it comes time to reboot, I run into the blank white screen followed by a flashing folder with a question mark on it. Looking into it, I believe what I need, is an EFI that I can set up from my newly created Ubuntu partition. So my question is this, is there an EFI that I can set up from Ubuntu, that will be recognized by a Macbook hardware, and run on startup?
Note: I was able to get back in to Ubuntu, by rebooting, and "trying Ubuntu" from my flash drive, and then logging in to my encrypted hard drive, but I no longer have Mac OS installed on my computer, so solutions that involve having mac os installed, while not impossible, are not easy.
