Bug#604155: Windows 7 not in grub menu

[Daniel Pocock <daniel@pocock.com.au>]

Subsequent to my last email, I think that the root filesystem was not 
mounted properly due to an unrelated issue, rebooting fixed it, this is 
the output from 30_os-prober:

# /etc/grub.d/30_os-prober
Found Windows 7 (loader) on /dev/sda1
menuentry "Windows 7 (loader) (on /dev/sda1)" {
   insmod part_msdos
   insmod ntfs
   set root='(hd0,msdos1)'
   search --no-floppy --fs-uuid --set a23821f33821c6df
   chainloader +1
}

and this is update-grub:

# update-grub
Generating grub.cfg ...
Found background image: moreblue-orbit-grub.png
Found linux image: /boot/vmlinuz-2.6.32-5-xen-amd64
Found initrd image: /boot/initrd.img-2.6.32-5-xen-amd64
Found linux image: /boot/vmlinuz-2.6.32-5-xen-amd64
Found initrd image: /boot/initrd.img-2.6.32-5-xen-amd64
Found linux image: /boot/vmlinuz-2.6.32-5-amd64
Found initrd image: /boot/initrd.img-2.6.32-5-amd64
done

So os_prober can find Windows, but it isn't in the menu

This is what I see in /boot/grub/grub.cfg after update-grub:

### BEGIN /etc/grub.d/30_os-prober ###
### END /etc/grub.d/30_os-prober ###
