After loading up 15.04 my laptop boots to the login screen and, when I enter my login code, it cycles back to the beginning of the boot process.
Any ideas how to fix this - I have no access to the Internet or any of my files !!!
Press Ctrl+Alt+F1 on your keyboard.
On the screen that appears, type in your username and password.
That logs you in. Next, run the command sudo apt-get update.
And then try to restart it afterward.
