release you still experience this issue.

Title:
  installer overwrites Mac bootloader, but cannot load a Mac OS

Status in grub-installer package in Ubuntu:
  Invalid
Status in ubiquity package in Ubuntu:
  Invalid

Bug description:
  The ubuntu 10.04 installer appears to correctly detect the existence
  of a Mac OSX installation, and lists it as an item in the bootloader
  menu at the end of the installation. However, when the system reboots
  it is in fact not capable of booting to OSX and so access to that
  operating system is no longer possible.

  Either there should be a warning that this is likely to happen (or
  that Mac/HFS+ is not actually supported), or if Mac is detected no
  bootloader should be installed by default, as the Mac one must be used
  in order to be able to dual boot with both Mac and Gnu/Linux.
  Overwriting the Mac bootloader with Grub simply causes problems and
  makes access to OSX impossible.
