I know this problem's thread are available but mine is different. I have two HDD installed. I have already installed ubuntu in /dev/sda1 and running fine. Now i install iMac in /dev/sba1 and that also running fine.
Problem is when i need to run mac then i need to select mac hdd as first boot from bios and same when need to boot on ubuntu.
I tried to add mac in grub (from ubuntu) but it did not work(latter i find the information that mac does not use MBR technique). Now i am trying to boot ubuntu from mac HDD.
From existing solution in internet they asked to create an empty partition and install ubuntu there. But i can do this. I have already installed ubuntu.
How to solve this problem? I need help. Thanks in advance.
Note: I have installed refit in mac. But does not show anything at start up.

I am not sure what is /dev/disk2. First two disk(disk0 and disk1) are real.
