I have a MacBook Pro (7,1) where I installed Ubuntu successfully. I have now changed hard drive, and restored MacOSX successfully.

I then went about restoring the ubuntu partition, and copied it across from the old disk with dd. Unfortunately, rEFIt doesn't recognise it as an ubuntu partition any more, and if I boot into it anyway it says "Missing operating system".

What can I do to restore my old ubuntu partition from the old hard drive to the new one? Am I missing any steps?

Have you tried booting from the boot manager? Hold/tap the OPTION key when restarting –  Jeremy Aug 14 '13 at 3:56
Yes, I get the same error message "Missing operating system" –  gozzilli Aug 17 '13 at 10:23
