Will this work? Adding Mac OSX to GRUB.

WinLinMac01 · #1 04-11-2008, 02:50 PM

Okay, I've decided to install Windows Vista, Mac OSX Leopard, and on top of them, Sabayon Linux with GRUB Bootloader. If GRUB fails to add Mac OSX to its boot list, can I add the following below to the grub.conf file to make Mac OSX bootable?

Below is the script-

title Mac OSX Leopard
root (hd0,1)
chainloader +1

Change root(hd0,1) with your OSX86 partition!

Please let me know. Thank you to all! I am also planning to stick with a MBR Partition Table and install Sabayon in one whole partition. I am installing these three O/S's on a single hard drive.

Users have also stated that the following simply works:

title Mac OSX Leopard
chainloader /etc/chain0

Is this true?

This will be my install order- Mac OSX-->Windows Vista--> Sabayon Linux--> Edit GRUB, and then all set to go.

To make GRUB boot OSX do the following.

First grab pc_efi_v80 (google for it)
copy boot_v8 to something like /boot/efi
Update your GRUB with:
title MacOS X
rootnoverify(hd0,3)
makeactive
kernel (hd0,1)/efi

where (hd0,3) is your OSX partition (I hope your OSX is already MBR) and (hd0,1) is your linux /boot partition (or / if you don't have separate /boot. Fix the path too in this case).
Windows is more simple:
title Windows XP SP2
rootnoverify (hd0,0)
makeactive
chainloader +1

where (hd0,0) is your windows partition.

btw, Tiger is ok with same setup as Windows

If you install linux on a different disk, you may not need to copy the efi_v8 file to the /boot/grub.

I have a triple boot Mac OS X, Win XP, Ubuntu 8.04 and my entry for Mac OS X (with EFI/Vanilla) is

<pre>
title Mac OS X 10.5.2 Leopard
root (hd1,0)
makeactive
chainloader +1
</pre>

By the way, this code goes into the file /boot/grub/menu.lst

Yep, I know that, thanks. Have you tried this on the same disk? Also, how would go about on installing Mac OSX? Should I install that before Windows Vista or afterwards?

I am sorry, but I don´t know how to do it with the three systems on the same disk.

Hopefully, someone who did it will help...

I'm interested in this too, I want to get windows xp and osx running on the same disk. I understand I will have to use mbr, and I don't mind using fat32 for windows. But how do I get them all installed?
I can install osx and make a fat32 partition, but then how do I get xp on to it? Will it work if I copy it from another disk using diskutil restore?
