LAPTOP Help-STUCK ON UPDATES?

I went to go on my laptop this morning and noticed that it was still doing updates from the night previous. It got to 100% quite quickly and wasn't slow or anything but now it's stuck on 100%. I've tried resetting it by keeping hold of the power button for 3 seconds and also taken the battery out but when I turn the laptop on it returns back to the same screen. The loading symbol is still moving and I can still move the cursor. Any help would be fantastic.
Additional:
laptop is a Lenovo
I have windows 8

Restart it and leave it for some time… It will get well soon.

Have you tried booting up in safe mode. That usually fixes booting problems. I'm not sure where to go from there but atleast you may have access to your laptop in safe mode

Ctrl at delete, close it out, if not then hold power button down till it shuts off remove battery press power button and hold for 30 sec then place battery back and power on, a recovery window should open asking different was to boot up pick the last one to repair itself if it finds something wrong. 2 answer get a 12ga. Shotgun, and have fun then use credit card and purchase a new one.
