Black screen when starting Windows 10?

Question

Windows

Long startup wondows and black screen on startup. Everything worked well and now it works, I don’t understand why this problem arose and how to solve it.

Answer 1

Black and black what do you "checkered" or go?
Until the heap, you can enter recovery mode and select boot logging.

Answer 2

"Black screen" is it instead of wallpaper or where is the black screen? It seems like at the end of the trial on an unregistered Windows there is a black desktop. It seems that in the lower right corner there is still an inscription about not being registered.
