A blue screen error (also called a stop error) can occur if a problem causes your PC to shut down or restart unexpectedly. When you experience this type of error, you won’t be able to see things like the Start menu or the taskbar on the screen when your PC is turned on. Instead you might see a blue screen with a message that your PC ran into a problem and needs to restart.
If you experience a blue screen error when upgrading to Windows 10, setup will automatically go back to your previous version of Windows.
