Lenovo 510p not starting after trying to restart into safe mode

[daanieel21]

Hi!
My lenovo Y510p worked fine an hour ago but then I wanted to restart the computer into safe mode. When the laptop tried to start the lenovo logo showed up as usual but the spinning thing ( which i think is showing when windows is booting) doesnt show up. It stays on the lenovo logo for 20 sec then it shutsdown and tries to start again but with the same result. I am very thankful for answers to this problem.

Hi Daniel,
Try unplugging all external devices from the computer (this includes USB flash drives, USB keyboards, Mice, external displays) and try booting the computer again.
Tell me how that works for you.
