Check the hard disk for errors
Again, a bad hard drive or bad sectors on the hard drive will cause the Windows 10 kernel security check to fail. Run the chkdsk build utility, which checks the integrity of the volume’s file system and corrects any errors in the logical file system.
- Open a command prompt as administrator,

Tip: CHKDSK does not stand for Check Disk, C: is the drive letter you want to check, /F stands for Disk Error Correction and /R stands for Recover Bad Sectors information.
