It sounds like your device has entered BitLocker recovery mode, which can happen after certain updates or changes to the system. Here are some steps you can take to try to regain access to your computer:
- Locate Recovery Key: Since you mentioned that you couldn't find the BitLocker recovery key in your Microsoft account, ensure that you check all possible locations where it might have been saved. This includes any USB drives, printed documents, or saved in Active Directory if your device was part of a domain.
- Use Recovery Options: If you have access to recovery tools, you can try using the recovery options provided by Windows. This may include using a recovery disk or USB that you might have created previously.
- Contact Support: If you are unable to find the recovery key and cannot access recovery options, consider contacting Lenovo support or Microsoft support for further assistance.
- Check for Updates: If you suspect that a recent update caused this issue, you might want to check if there are any known issues with the update you installed. Sometimes, rolling back to a previous version can help if the update is causing problems.
- BitLocker Repair Tool: If you can access another computer, you might consider using the BitLocker Repair Tool to attempt to recover your data. This tool can help in some cases where the drive is accessible but locked.
Remember, without the recovery key, it may be difficult to access the encrypted data on your drive. It's crucial to keep a backup of such keys in a secure location to avoid similar situations in the future.
