Cause

The most probable cause for the issue is a virus or malware affecting the system. However, that might not be the only cause. Another reason could be that a newly installed program might have messed up the files.

Preliminary steps

1] Run a full system anti-virus and anti malware scan.

2] Uninstall recently installed programs, even if they are important ones. Check if it helps with the issue. They could be reinstalled later.

Thereafter, proceed to the following solutions:

1] Rebuild BCD and Fix MBR

2] Run an SFC scan

3] CHKDSK scan

Solution 1] Rebuild BCD and Fix MBR

1] Search for Command Prompt in the Windows search bar and right-click on the option. Select Run as administrator.

2] Type the following command and press Enter to run it:

bootrec /rebuildbcd

Rebuild Bcd

3] Now type the following command and press Enter to run it and get a new bootloader:

bcdboot c:\windows /s c:

Bcdboot



4] Restart the system once both the command have executed.

Solution 2] Run an SFC scan

Since the issue is that the security files in the system have been modified, an SFC scan could be very helpful in resolving the problem. Here’s the procedure for an SFC scan.

Solution 3] CHKDSK scan

A CHKDSK scan helps in checking the bad sectors in a hard drive. Here’s the procedure for a CHKDSK scan.

Hope it helps!
