I am attaching a screen shot of my problem because it looks so similar and I haven't had any luck in solving it. I can still boot with the Linux 3.19.0-21-generic kernel from the Grub menu. However the more recent versions (22 through 25) are not booting. I am not sure how to tell for certain but it looks more and more like the same kind of problem.
