Grub2 wont boot osx like grub used to

[dooglex]

Grub problems after update to 9.10 with OSX and custom boot options Hi,

I used to boot OSX using menu.lst which looked like this:

title OSX

rootnoverify (hd0,2)

savedefault

makeactive

chainloader +1

 

now i have done a clean install of 9.10 which finds the osx partition but when i boot it get only the attached screenshot of output, and then nothing.

Im not 100% sure that its not grub crashing and not the osx bootloader, but if grub has handed over then this belongs on an ubuntu forum instead sorry! I will close and move it.

 

I tried to add a custom entry in 40_custom then adding +x priveledges and then running update grub2 and the grub.cfg shows the new entry but on boot no new options appear so I cant test adding my own options!

 

So in summary does anyone know why my custom created entry in 40_custom doesn't even appear let alone work? (attached at end) or for full marks why grub2 wont natively boot osx!

 

thanks
