On my system I found an unmatched curly bracket in /boot/grub/grub.cfg after the end of the last menuentry of this submenu for older kernels:
menuentry 'Ubuntu, with Linux 3.2.0-36-generic (recovery mode)' --class ubuntu --class gnu-linux --class gnu --class os { [ ...SNIP...] initrd /boot/initrd.img-3.2.0-36-generic } } <------ BAD BOY ### END /etc/grub.d/10_linux ### I uncommented "BAD BOY" and everything was fine.
