Multibooting - Win XP, Vista, 7, Ubuntu Linux and Mac OS X - Help with Grub?

[Arus]

I was wondering if anyone here can help me with my little project.

I am trying to make an 'OS Test' PC.

I want it to have the following:

Windows XP, Vista, 7 (RC), Ubuntu Linux and Mac OS X Leopard (Kalyway).

I already have them all installed as below:

Windows XP (hd0,0) - Primary, Active

Windows Vista (hd0,1) - Primary

Windows 7 (RC) (hd0,2) - Primary

Ubuntu Linux (hd0,4) - Logical

Mac OS X Leopard (hd0,6) - Logical

 

Using Grub4Dos, I have managed to get all OSs working, apart from Mac OS...

The Menu.lst is as below:

 

title Windows XP

root (hd0,0)

chainloader /ntldr

 

title Windows Vista

root (hd0,1)

chainloader /bootmgr

 

title Windows 7 (RC)

root (hd0,2)

chainloader /bootmgr

 

title Ubuntu Linux

root (hd0,4)

chainloader +1

 

title Mac OS X Leopard

root (hd0,6)

chainloader +1

 

Can Grub4Dos load Mac OS?

Is there something I have done wrong?

Is there something I should do?

 

Thanks

Simon
