I recently installed Ubuntu 13.10 on a new MacBook Pro (Late 2013, 13-inch Haswell retina). After installation, I could not boot to Ubuntu. It turns out that the installation correctly added an EFI boot entry, Boot0000, for ubuntu, but did not update the EFI BootOrder. The BootOrder was set to be 0080, a boot entry for MacOS. The correct BootOrder should be 0000,0080. I used the command 'sudo efibootmgr -o 0,80' to fix it. The installation should have set the boot order information. I observed the same problem on a second laptop.
Other information that might be helpful: 1) My installation media was a USB drive created using the standard iso image, not the MAC iso. The latest Apple hardware can boot the UEFI/BIOS hybrid image. 2) If a user never booted to MacOS before installing Ubuntu, the EFI would not have any boot entries and the BootOrder would be empty. But if a user had booted to MacOS, the EFI would have two identical boot entries Boot0080 and BootFFFF and the BootOrder would be 0080.
Another issue is that the grub entries Ubuntu created for MacOS can not boot to MacOS. I "solved" this by creating a grub entry to have a single command "exit". This way, the system would exit grub, and EFI would boot the second in line according to BootOrder.
