OK, I think this is a pretty easy fix.
First I must say that I have no experience with Mac or hfs+.
But the results.text seem to indicate that everything is all right. You have menu entries for both Mac and MS.
The problem seems to come from when you installed. Your 10.04 grub was, as it needs to be, installed on the MBR (sda not sda5). It is still there and looking for the source files in your now gone 10.04 install.
You will need to correct this problem.
Read that section of that site. Will give you several options using the LiveCD. I have never used the graphical tool in the Live Session. I have always chrooted in and used just run the commands. I hear the graphical tool works though. Quit using Ubuntu before that came out.
If that does not work just continue on in that same section and it will give you instructions for using the terminal. Note that you do have the results.test and that gives you all the info on the partition you are installed on (sda5) and you only have sda
This should straighten you out.
The only thing that concerns me is that you seem to have files for grub-legacy also. This could through a monkey wrench in the works. This can be dealt with if it is a problem.
Give the direction on that link a try. It is easy and should work. If not we will approach it another way.
