We recommend that you repair your computer at startup and check if it helps.

  2. If you receive a message asking you to press a key to boot from the DVD, do so.
  3. If the Install Windows page appears, press or click Repair Computer to start Windows Recovery mode.
  4. In the Windows recovery environment, tap the Select option screen or click Troubleshooting.
  5. Click on Advanced Options.
  6. Then click on StartupRepair.

Running DISM (Deployment Image Servicing and Management)

Users of Windows 10, Windows 8.1 or Windows 8 must first run the DISM (Deployment Image Servicing and Management) tool before they can run System File Checker. DISM uses Windows Update to provide all the files needed to troubleshoot errors. If you skip this step, System File Checker may not work. Windows 7 and Vista users can skip this step.

Type the following three lines in a row:

DISM.exe /Online /Cleanup-image /Restorehealth
Dism /Online /Cleanup-Image /ScanHealth
Dism /Online /Cleanup-Image /RestoreHealth

Restart when all steps are completed.

Starting in Safe Mode and in Clear Space

As some users have pointed out, this particular problem can also occur in situations where the system does not have enough space to boot, as well as in third-party processes and services that need to be loaded during the boot process. If Windows tries to load everything during the boot sequence and fails, it automatically switches to diagnostic mode to find out which component fails.

However, in situations where the required space cannot be freed up, the PC remains blocked in loop diagnosis mode. Several users in the same situation could eventually solve the problem by starting their computer in safe mode and freeing up space.
