Hello hussien mohamed2,
thank you for posting on the Microsoft Community Forums.
If you have enabled BitLocker on both drives, you should have received two recovery keys. If you have only received one recovery key, it is possible that you have accidentally saved or deleted the other one. To recover the missing recovery key, you can try the steps in Find your BitLocker recovery key - Microsoft Support.
**Important:**Microsoft Support is unable to provide, or recreate, a lost BitLocker recovery key.
Best regards,
Lei
