Title:
  GRUB cannot boot into MAC OS X

Status in “grub2” package in Ubuntu:
  New

Bug description:
  Binary package hint: grub

  After installing Ubuntu 10.10 on a Mac Book Pro 7,1 GRUB recognises
  and displays boot options for Mac OS X. There are two entries (32 and
  64 bit) that do not boot from GRUB:

  ### BEGIN /etc/grub.d/30_os-prober ###
  menuentry "Mac OS X (32-bit) (on /dev/sda2)" {
  	insmod part_gpt
  	insmod hfsplus
  	set root='(hd0,gpt2)'
  	search --no-floppy --fs-uuid --set 81604fb7a249b2f4
          load_video
          set do_resume=0
          if [ /var/vm/sleepimage -nt10 / ]; then
             if xnu_resume /var/vm/sleepimage; then
               set do_resume=1
             fi
          fi
          if [ $do_resume = 0 ]; then

             fi
          fi
  }

  
  Workaround:
  Press Alt while booting and this should bring you to the Apple Boot Manager. From here you can select to Boot Mac or Windows. Select Mac and OSX will load. Select Windows and GRUB will load.
