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?
