Unmountable Boot Volume then Black screen


Sep 11, 2017
Hello I have a Lenovo Ideapad Z510. My laptop right now starts with lenovo with circle progress below after that it shows Unmountable Boot Volume error and restart itself with automatic repair after that it shows a black screen with only the mouse cursor functioning.
Try re-seating the hard drive. Did this happen after any other issues? System dropped or any other error messages happening before? Is the drive a solid state or platter? If platter is it making any odd noises like grinding or clicking?

Chances are that the drive is bad and needs to be replaced.
