HOW TO: Make Antergos (Arch) Boot OS X DVD to Restore Mac for Dual-Booting

AprilShower · 05-07-2015, 04:02 PM

I clean installed Antergos 64bit (GNOME 3) on my iMac, and now need to boot the OS X DVD that came with the computer to format and restore. The ultimate goal is to keep this machine for dual-booting (which I can take care of) since there are simply things I need from both operating systems. If only Antergos or GRUB would boot from the DVD to kick-off the process.

What have you done so far?

It made sense to install rEFInd on this machine, since that was the program that helped OS X boot the Antergos image from my USB drive in the first place.

I followed the steps laid out in the Arch Wiki.

First, by using the refind-install command

Then used the refind-install --usedefault /dev/sda1 command to "also install rEFInd to the default/fallback boot path".

I shutdown, and booted the Mac up in hopes to catch rEFInd's splash screen, but to no avail. Only the Antergos/GRUB screen, and then into Antergos as usual.
(This began a hopeless cycle of re-installing, and rebooting which lasted quite some time.)

Afterwards, I tried manually installing rEFInd using the following commands from the Arch Wiki:

Quote:

cp /usr/share/refind/refind_x64.efi $esp/EFI/refind/
efibootmgr -c -d /dev/sda -p 1 -l /EFI/refind/refind_x64.efi -L "rEFInd Boot Manager"

Also, I installed the mactel-boot utility from the AUR.

And according to the efibootmgr utility, rEFInd was now first in the boot order:

Quote:

BootCurrent: 0002
BootOrder: 0004,0003,0002,0080,0001,0000
Boot0000* ubuntu
Boot0001* rEFInd Boot Manager
Boot0002* antergos_grub
Boot0003* rEFInd Boot Manager
Boot0004* rEFInd Boot Manager
Boot0080* Mac OS X
Boot0081* Recovery OS
BootFFFF*

After shutdown/power-on, the machine displayed alot of white-colored "clearing node" text, before tragically booting once again into Antergos/GRUB.

I've also read How-to Geek's guide on re-installing OS X on Mac, yet the tutorial never mentions how to restore it from Linux.

Conclusion:

What piece of this puzzle am I missing? Would creating a LiveUSB of OS X be an easier route than this DVD? Is there a GRUB command I'm not aware of that can change the boot order?

I'm almost certain rEFInd is not the only way Linux would be able to boot this OS X DVD, it's just the only way I've known how so far.

I can clearly see the Mac OS X boot option in efibootmgr as Boot0080*, so at least it's being recognized. When Antergos boots to the desktop, the OS X DVD is displayed as "WindowsSupport" if that helps.
I'm out of my element and am at an impasse, your help will be appreciated.

PLEASE & THANK YOU

Is this not a function of the Mac hardware? : "Holding down the Option key during startup will show you a boot screen with all bootable devices listed." i.e. should show the boot DVD.

I could be wrong. (i should always append my posts with this.)

Actually, there is an alternative key also. press and hold the "C" : https://support.apple.com/en-us/HT201255

If it an older iMac, the keys may be diffrent: http://osxdaily.com/2007/01/12/10-mu...rtup-commands/

Thanks for replying sudowtf,

I recently tried the Hold-C option, only to find that the Mac simply boots into the GNU Grub v.2.2 Beta 2 command line.
After, I hit ESC and was then prompted (as usual) to choose between Antergos Linux or Advanced Options for Antergos Linux
Under Advanced Options for Antergos Linux only two options are listed: 1. Antergos Linux 2. Fallback Antergos Linux

When I use the ls command in the GNU Grub v.2.2 Beta 2 command line, the following are listed:

Quote:

(hd0) (hd1) (hd1,gpt4) (hd1,gpt3) (hd1,gpt2) (hd1,gpt1) (cd0)

When I then use the ls -l command, the following are listed:

Quote:

Device hd0: No Known Filesystem Detected
Device hd1: No Known Filesystem Detected
Partition hd1,gpt4: No Known Filesystem Detected
Partition hd1,gpt3: Filesystem type ext* - Label 'AntergosRoot'
Partition hd1,gpt2: Filesystem type ext* - Label 'AntergosBoot'
Partition hd1,gpt1: Filesystem type fat - Label 'UEFI_SYSTEM'
Device cd0: Filesystem type iso9660 - Label 'WINDOWSUPPORT'

I tried using the efibootmgr -o 0080,0081,0001,0003,0004,0000,0002 command to change the boot sequence, making Mac OS X and Recovery OS the first two boot sources.
No cigar for that either, antegros_grub boots as usual.

I just recently installed Grub Customizer from the AUR, just to keep the hope alive.

I also tried the other Mac boot commands listed in both of your links, with unfortunate success.
BUT I'm not losing faith..
