Is there a way to boot into grub on a mac rather then OSX?
Solution 1
This is how, macs either boot in bios/csm or EFI mode, so if the wrong boot mode is selected it wont boot the right away.
- You can change it by selecting the startup disk, rebooting to macOS is EFI (even if its not macos),
- the others are BIOS (it is expecting to boot windows) and it will load regular bootloaders.
- The third option is to have macos-like efi or boot partitions with other bootloaders inside.
If you dont have macos/win installed then use the macos install media to switch the setting.

I have successfully installed Ubuntu 14.04.2 on a Mac Mini(late 2014).Now I can get to the new installation by pressingAlt > EFI BOOT to get to GRUB and selecting Ubuntu to boot the OS. My question is How can I boot into GRUB without pressing Alt >GRUB. I would like GRUB to come up before anything else.
I know some tools like reFIND to dual boot with OS X. but, I don't want to install reFIND because of various issues like when I install it (My screen goes to black whenever I preform a full shutdown, reFIND still appears but, due to the monitor being off for some reason I cannot see my boot menu. The only way I am able to get my monitor working is to bypass reFIND(which I removed) by reseting the NVRAM(Windows Key + Alt+ R +P).
What I want:
I would like GRUB to show up like reFIND show up on boot without being triggered by startup manager (or other). I have moved
/boot/efi/EFI/Ubuntu/grubx64.efi
to/boot/efi/EFI/boot/bootx64.efi
. I have tried refind but, encountered problems.Note: Both OS X and Ubuntu installed in EFI mode(and that's the way I'd like to keep it).So is this even possible?
