Ubuntu 16.04 crash. How do I recover?

Question

While I was doing my project which consists of OpenCV programming, everything crashed and I can not log into Ubuntu. It shows me the screen below. Even when I try the options given, it does not lead me back to my normal Ubuntu OS. Please help, I have important project files inside there that are due.

About your issue:

• Keep Calm, if you didn't do anything else, your files are in the hard drive.
