Problem booting into os x after clean install of Ubuntu 10.4 on a separate drive

[Ijon Tichy]

The hardware is a psystar box with 2 drives for os x and ubuntu respectively.

 

I attempted install of ubuntu over older version of xubunut without physically disconnecting the os x drive :-(

After install I could not boot into either system. THEN I remembered something about the install problem that 10.4 has and installed ubuntu again, this time following the instruction regarding booloader install.

 

Now I can boot ubunut fine, but of course when I select drive holing os x it hangs on 'Verifying DMI pool data....'

 

I've been looking at some thread on here about dual boot problems with Win7 and such, but are any of the recommended diagnostic and repair steps relevant to my case, specifically testdisk and bootinfo scripts? (something I found on Ubuntu forums)

 

I did not have a chance to run boot info yet, but will later tonight.

 

Thanks in advance!

... here's the result.txt from running BootInfoScript

 

I take it this is a hint, but I wish I knew what to do with it :-(

 

 => Grub 2 is installed in the MBR of /dev/sda and looks at sector 126113320 
 of the same hard drive for core.img, but core.img can not be found at this 
 location.
