Windows 10: secure boot violation

Bonjour,


suite à une mise à jour de mon ordinateur, je rencontre plusieurs soucis lors du redémarrage.

Dans un premier temps le défaut suivant s'affiche: secure boot violation Invalid signature detected. check secure boot policy in setup.

Je tape sur entrer puis l'ordinateur se dirige directement sur le bios. Ensuite impossible de démarrer l'ordinateur.


J'arrive à supprimer le défaut en désactivant secure boot control dans le bios.

mais malheureusement le PC ne démarre toujours pas et je suis toujours redirigé vers le BIOS.


Je ne sais plus quoi faire, aidez moi je désespère.


Merci d'avance

:)

 

Secure Boot Violation error

Hi,



Thank you for writing to Microsoft Community Forums.



I understand that you receive a warning regarding Secure Boot Violation when booting the PC. For further clarity on the issue, please respond to the questions below:

1. 
   
   1. What is the make and model of the PC?
      
   2. Which build version of Windows 10 are you using currently?
      

Meanwhile, I would suggest you to follow the steps mentioned below and see if that helps.



Method 1:



Try loading the BIOS to default settings and see if the issue persist. You may want to get in touch with the manufacturer of the PC for further assistance with resetting BIOS.



In addition, you can check if any update for BIOS is available and try updating the BIOS by contacting the manufacturer.



Note: Modifying BIOS/ complementary metal oxide semiconductor (CMOS) settings incorrectly can cause serious problems that may prevent your computer from booting properly. Microsoft cannot guarantee that any problems
resulting from the configuring of BIOS/CMOS settings can be solved. Modifications of the settings are at your own risk.



Method 2:



Disable Driver Signature Enforcement, and see if you are able to boot to Windows normally.

1. Now press Windows +
   S key together to open Search.
   
2. Now type CMD and select Run as administrator.
   
3. Accept the UAC prompts.
   
4. Type in the following command and hit Enter:
   
   bcdedit.exe /set nointegritychecks on
   
5. Restart the PC
   

Let us know how it goes.

If you can, try resetting your BIOS defaults.

Secure Boot Violation

I have searched for an answer to my problem but I can't find one.

When I start my PC, it starts with the lenovo logo and then shows:

Secure Boot Violation

Invalid signature detected. Check Secure Boot Policy in Setup

Ok

I have disabled Secure Boot and it just stays on the Lenovo logo.

Please help cause I need it for school work.
