When the computer was restarted, there was a problem loading the NTFS file system and the computers could not be started. In other words, the “chkdsk” command had broken the NTFS file system after the new update. The cause of the error and the reasons for its occurrence are listed as follows:

  • Systems with Windows 10 20H2 installed are affected.
  • The problem is affecting SSDs .
  • The KB4592438 update released on November 8 seems to be the source of the problem.

Therefore, administrators are advised to back up Windows before using the “chkdsk” command .
