Question

Recovery bitlocker non reconnue et je ne peux plus utiliser mon ordinateur

Answer 1

Si votre disque est chiffré avec BitLocker, la clé de récupération BitLocker est automatiquement enregistrée uniquement sur le compte Microsoft associé (voir le lien ci-dessous). Vérifiez tous les comptes Microsoft utilisés sur l'ordinateur, ainsi que les comptes professionnels ou scolaires qui y sont liés.

Avez-vous trouvé la clé de récupération BitLocker sur un compte utilisé ou lié à l'ordinateur portable ?

Sinon, disposez-vous d'une sauvegarde de vos fichiers ou utilisez-vous un service cloud comme OneDrive pour les synchroniser en ligne ?

Answer 2

If your BitLocker recovery key is not recognized and you cannot use your computer, you may need to follow these steps:

1. Check Recovery Key Sources: Ensure that you have checked all possible locations where your recovery key may be stored. This includes:
   • Your Microsoft account (if you saved it there).
   • Printed copies or USB drives where you might have saved it.
   • Active Directory if your organization manages BitLocker keys.
2. Use BitLocker Repair Tool: If you cannot unlock the drive with the recovery key, consider using the BitLocker Repair Tool (repair-bde.exe). This tool can help recover data from a damaged drive. However, it requires the BitLocker key package and the corresponding recovery password.
3. Seek Help: If you are unable to recover the key or access your data, consider contacting your IT support or a professional service for assistance.
4. Recovery Environment: If Windows does not start, you might need to boot into the Windows Recovery Environment (Windows RE) to troubleshoot further.

It's crucial to ensure that you keep your recovery key in a safe and accessible location for future use.
