How to Fix the “Preparing Security Options” Error on Windows

chkdsk C: /f /r /x

Note: Make sure that you use the drive letter where Windows is currently installed.

Note: In the above command, C: is the drive on which we want to run check disc, /f is a flag that tells chkdsk to rectify any faults on the drive, /r tells chkdsk to look for damaged sectors and perform recovery, and /x tells check disc to dismount the drive before starting the procedure.
