I've been having some trouble dual booting Kali Linux on my macbook pro. I burned the .iso to a dvd and partitioned my drive. Got all the way through the install with what seemed like no problem. After I ejected the dvd and tried to boot into kali from rEFit I get the message No operating system installed. If I insert the disc I can run kali off the disc on my machine just fine. I'm not sure why it isn't installing to the hdd, I have tried the install a few times and the same thing keeps happening.

Any ideas as to what I'm doing wrong?
