I have a Compaq CQ58 laptop and I installed Ubuntu 14.04 LTS. After being prompted, I have updated it to the new LTS version. And after updating, everything just went to black after the reboot and am not able to log in.

Is there any way to fix this without reinstalling the OS or at least without data loss?

First of all try to open in command line mode. You can do that by pressing Ctrl+Alt+F2. You will be asked to login with your username and password.

Once you are logged in then you can check your files, for instance type ls to see files and folders list.

Now try this : 

sudo service lightdm stop
sudo apt-get update
sudo apt-get install gnome-shell
sudo apt-get install ubuntu-gnome-desktop
