I faced the same issue with my Lenovo G50. It all started asking me to update where I accepted and left it. It took a day still not updated so I removed my battery and started then it showed me that message in blue screen Then I did this and it worked..!!! *Press Ctrl alt delete ..... * make sure your laptop is connected to WiFi if it is previously connected it will auto connect. * then it started autoupdating using my WiFi * and finally got updated. It worked for me I didn't tried on any other laptop .
