os-prober not detecting Arch install

I'm triple booting osx, win 7 and arch on an apple macbook pro 8,2

I've followed the guide specific for my macbook pro here: https://wiki.archlinux.org/index.php/Ma … ook_Pro%29

As well as the beginners install guide here: https://wiki.archlinux.org/index.php/Beginners%27_Guide

Everything has gone well and I can boot and login fine.

However I've come to a problem whilst trying to configure grub2.

I've run this and I've verified that its worked correctly

# modprobe dm-mod 
# grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=arch_grub --boot-directory=/boot/efi/EFI --recheck --debug
# mkdir -p /boot/efi/EFI/grub/locale
# cp /usr/share/locale/en\@quot/LC_MESSAGES/grub.mo /boot/efi/EFI/grub/locale/en.mo

However when I run,

# grub-mkconfig -o /boot/efi/EFI/grub/grub.cfg

Whilst the config generator is running it spits out text from os-prober. It lists my osx and Windows partition but nothing about Arch.

The config file generated doesn't contain any information about Arch either and when I try boot into grub2, it lists 2 Mac OSX partitions, 32 and 64 bit (I'm thinking that one might be a osx's "Recovery HD") and neither boot as well as a Windows 7 partition that doesn't boot either.

I think a big part of the problem is that os-prober isn't detecting the installations correctly. Does anyone have any idea why this would be?

Cheers

Re: os-prober not detecting Arch install

Well, have you actually run

 os-prober 

and seen the output? Can you post that output here?
For my macbook pro, I had to run os-prober and then the grub-mkconfig worked correctly.
