Fixing Kali linux errors. (startx not found, "oh no! something has gone wrong")

After your fresh install of kali, you might run into some problems.

One of them consists of the login screen missing and returning:

"Oh no! Something has gone wrong.

A problem has occured and the system can't recover. Please contact a system

administrator"

To fix this issue (a temporary fix), press CTRL+ALT+F1, it will take you to the terminal. 

From 

there, check if you can use the command "startx"

If you get the following error:

root@kali:~#startx

-bash: startx: command not found

The problem would be that you don't have the x window system functioning yet, install it by 

using the command:

  apt-get install x-window-system

Let it install and from there, you should be able to access your graphical user interface using 
"startx"

If you still get the error message, go into your BIOS and Enable the Virtual setting. This is 
what fixed my problem. 

Don't forget to make sure that all your packages are up to date.
