Triple boot gone wrong

[bigonroad]

Ok, So i had xp installed. thats hd0.

Then i installed mac os onto the first partition on hd1.

And then i installed linux onto the back end of hd1.

 

Linux installed grub, from which I can boot into windows or linux BUT, I cannot boot linux.

 

I inserted the line below:

 

What should i change

 

title Microsoft Windows XP Home Edition

root (hd0,0)

savedefault

makeactive

chainloader +1

 

# inserted this line

title Mac os

root (hd1,0)

savedefault

makeactive

chainloader +1

chainloader +1

 

and:

title Mac os

root (hd1,0)

chainloader --force +1

I have GRUB installed on hd0, OSX on hd1, and I can boot into OSX from GRUB using the PC_EFI_v9 method detailed by wmarsh around here. Look him up, look for his guide. I actually modified it a bit, and I'm now tinkering with a new installation, so I'll check in next weekend when I've got my ducks in a row to see if I can help more. For now, look to wmarsh. He's got it dialed.

 

The key, I think, is that GRUB needs to pass off the boot process to something that can emulate or initiate EFI, and then OSX has what it needs to boot. I may be wrong, but I know it works for me.
