Macbook pro retina Weird problem

[ftwr]

Hello guys,day before yesterday i upgrade my OS Yosemite to OS Sierra,and then did some stuff and turn off the Macbook,and the weird thing is yesterday morning when i try to turn it on ,it booted up normally,came to the login screen,but after i enter the password the progress bar goes sometimes half or less and then screen goes black but Macbook still on,so i went to recovery using Command+R and then disk utility,and yesterday my Macintosh HD was unmounted in here

and i munted it back ran First Aid but didn't show any errors.so i Restore my mac using Time machine backup yesterday and my mac worked again,and i turn it off yesterday night and today it won't even go to the login screen,please help me to solve this,also i can't use Shift key for safe boot,it doesn't work.

EDIT- i Restore my mac using Time machine backup just now and it worked,i logged in,and then i shut down my laptop to see and now same problem again
