No initrd for the first entry, plus it somehow got a symlink for the actual kernel.
So just do this: sudo rm -f /boot/vmlinuz sudo update-grub Life should be good after that. Most likely you or something else modified (or removed) /etc/kernel-img.conf, which is what tells it to create or not create this symlink. ** Changed in: linux-source-2.6.15 (Ubuntu) Status: Needs Info => Rejected -- Booting w/new kernel impossible https://launchpad.net/bugs/53492 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
