After a major crash or system problem (e.g. **system thread exception not handled**), you will get the Windows 10 BSOD (//Blue Screen of Death//). See the example screenshots in:
  * [[https://www.drivethelife.com/windows-10/system-thread-exception-not-handled-windows-10.html|Fix SYSTEM THREAD EXCEPTION NOT HANDLED in Windows 10]]
  * [[https://www.drivereasy.com/knowledge/fix-system-thread-exception-not-handled-bsod-error/|Easy to Fix System Thread Exception Not Handled Error]]

If the disk is not too damaged, Windows will automatically reboot into the **Windows Recovery Environment** and display a //Recovery// screen (see screenshot of [[https://www.drivethelife.com/windows-10/system-thread-exception-not-handled-windows-10.html|Solution 4]]) or //Réparation Automatique// screen.

Select //Advanced options// and then //Troubleshoot// (or //Dépannage//).

You can then choose between:
  * a complete //Reset// of Windows 10
  * or additional //Advanced options// that may help you save the PC
    * Booting in Safe mode is available in the //Startup settings// (//Paramètres//) option
    * You can also restore your system in a previous state if you created a [[https://support.microsoft.com/en-us/help/4027538/windows-create-a-system-restore-point|system restore point]] or a [[https://support.microsoft.com/en-us/help/4026852/windows-create-a-recovery-drive|recovery drive]]

===== Complete reset =====

Follow the steps in [[https://support.hp.com/us-en/document/c04742289#AbT1|Performing a push-button reset through Windows Recovery Environment]]

Note: if you have several disks and you get an error after choosing the option to remove the files from //All Drives//, try again and use the option to remove the files from //Only the drive where Windows is installed//

==== The reset works ====

If you can perform the complete reset, you can go to the [[other:win7towin10#basic_windows_10_installation|Basic Windows 10 installation]]

==== The reset does not work ====

If the complete reset does not work, you will probably have to [[other:win7towin10#no_recovery_partition|use an installation media to reinstall Windows 10]]
