I need to know the optimal procedure for deleting OSX and installing gentoo using the EFI stub kernel so I don't need to install a separate boot loader. I'm not sure what method I need to use to install gentoo. Any help would be GREATLY appreciated. |

Could you tell me how I can actually boot into the live cd so I can use those? |

I recommend against trying to use the EFI stub loader directly in this way, especially on a Mac. Although it can be done, it will limit your options greatly in terms of installing multiple kernels or modifying kernel options at boot time, both of which can be critical when dealing with recovery situations. The biggest problem is that the EFI provides limited options for passing parameters to the boot loader, so you'll need to embed your options in the kernel itself, where they can't be easily changed.
That said, the EFI stub loader itself is perfectly OK; I just recommend that you use it in conjunction with rEFInd, gummiboot, or some other boot manager.
OTOH, one of the problems with Macs is that their EFI is non-standard. You may need to use the "bless" utility to adjust the boot loader configuration. This tool ships with OS X, but there's a limited port to Linux. In Fedora, it's in a package called "macutils" or something similar, IIRC. I don't know if it's available in a Gentoo package. Alternatively, some Macs will boot the EFI boot loader that has the fallback filename (EFI/BOOT/bootx64.efi on the ESP).
Because of these problems, a Linux-only install on a Mac generally goes easier if you treat the computer as if it were a BIOS-only system: Create a Master Boot Record (MBR) partition table and install with a BIOS-mode boot loader. (Unfortunately, using either MBR or a hybrid MBR is required to activate the Mac's CSM, which is needed to boot in BIOS mode.) |
