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.

Do you still have this copy of Ubuntu installed? If so, please run `sudo apport-collect 606289`. This will attach the log files in /var/log/installer, which we'll need to get to the bottom of this.

I'm afraid not. I had this problem about 10 months ago with a friend's machine. I don't currently have access to any mac machine. Sorry!
