  • You forced a system shutdown while disk writing was still in process.

You can use the “bootrec /fixboot” command to repair similar issues. But, some users receive an error message denying access to bootrec /fixboot.

We will also recommend taking a backup of all your data before performing any action. There is no better tool than the MiniTool Partition Wizard Bootable to keep a backup of the system disk.
