Hello Roccojun,

 

A BIOS update can trigger BitLocker recovery, especially if TPM-related settings or secure boot measurements have changed. In that case, Windows may require the recovery key before allowing access to the drive.

 

If the recovery key from your Microsoft account is being reported as invalid, I would first verify that the Recovery Key ID displayed on the recovery screen matches the Recovery Key ID associated with the key stored in your Microsoft account. It is not uncommon to find multiple recovery keys linked to the same account.

 

A few questions:

 

* Does the Recovery Key ID on the screen match the one in your Microsoft account?

* Was the SSD ever moved from another PC?

* Is this a personal device or one managed by an organization?

 

If the key IDs do not match, the correct recovery key may have been saved to a different Microsoft account, a work/school account, or backed up elsewhere when BitLocker was enabled.

 

Regards,

Kadir O.
