HP,

Check out this link. I used it as a reference to get myself up and running.

I didn't need to go through all the steps there though, mine were much more condensed. Here is what I did.

1.) Using Mac OS Disk Utility, Partition hard drive to desired size.
2.) Using a bootable thumbdrive with Ubuntu installed, boot from drive and install like normal.
3.) After installation is complete, reboot into Mac OS, install refind.
4.) Reboot, select /efi/grubx64.efi (First Option)
5.) Grub will appear, select Ubuntu
6.) Enjoy.
