good day friend
before devoting more time to examining sectors of the hard drive to which in this forum you will spend countless programs that would take a good time
I would recommend you from experience to backup your information and reinstall the windows again from zeros and without leaving partitions
Only the one that the system creates for you
because if your hard drive did not suffer from any blow or fall and I see no reason to be wasting time in repairing damaged sectors when the fastest effective solution is formatting but if you want to try
is the program
EaseUS Partition Master EaseUS DiskChekUp Paragon Partition MiniTool partition Wizard: DataRecovery
etc and so we can follow
