For me this problem was fixed by uninstalling the HP recovery stuff from windows as it was overwriting parts of grub2 at every opportunity. I don't know if this is a good solution. But HP:s stuff assumed there was an ntloader and wrote stuff where ntloader shouldn't be without checking if the space was free, thus rendering the system unbootable.
