The problem is solved and here's what happened:
I tried to repair the system with windows disk but it couldn't find the problem. Then I switched to legacy system (as Eton pointed out) but that didn't help either. Again I used the repair tool from windows disk (with legacy on) and it actually worked. System restarted and windows started up.
Honestly I had not been facing this kind of problem and it was slightly weird cause I really did nothing which would be turned into the cause of this problem.
