Bit locker key is not available on devices I have, but newer devices do have bitlockers

To recover BitLocker keys for older devices, you can follow these steps:

1. Check Microsoft Account: Ensure that you are logged into the correct Microsoft account that was used for the previous devices. You can access your BitLocker recovery keys by visiting https://myaccount.microsoft.com and navigating to the Devices tab. From there, select the device you want to retrieve the key for and choose View BitLocker Keys.
2. Contact Helpdesk: If you are unable to find the keys through your Microsoft account, consider reaching out to your organization's IT helpdesk (if applicable). They may have access to recovery keys stored in their systems.
3. Use Recovery Options: If the recovery key is not available online, you may need to check if the recovery key was saved to a USB drive or printed out during the initial BitLocker setup.
4. Self-Recovery: If you have access to the recovery key, you can enter it during the boot process when prompted by BitLocker. If you encounter issues, you might also try connecting the SSD to another device as a secondary drive to access the recovery options.
5. Helpdesk Procedures: If you are part of an organization, ensure that your helpdesk has procedures in place for retrieving recovery information securely.

If your older devices are not showing up, it may be due to the fact that they are not currently active or connected to the Microsoft Entra ID. In such cases, contacting support for assistance may be necessary.

If your drive is encrypted with Bitlocker, the only place the Bitlocker Recovery key is automatically stored is on the associated Microsoft account on the link below, be sure to check any Microsoft account that may have been used on the PC and also any work or school account that may be linked to the PC.

Are you able to find the Bitlocker Recovery Key on any account that may have been used or linked to the laptop?

If not, do you have a safe backup of your files, or use a cloud service like OneDrive to sync your files online.

If you are unable to find the Bitlocker Recovery Key on any account that may have been used on that device, then I am sorry for the bad news, the only way to access that device is to create a bootable Windows 11 USB on another working PC and use that to clean install Windows and at the start of the installation, delete all partitions on the drive to remove the encryption, which will sadly result in loss of all data on the drive.
