Windows 10 - Preparing BitLocker recovery in black screen, how to use my recovery key

After few times of typing password incorrect my Windows 10 was put in BitLocker Recovery. When I turn on my HP Envy x360, 1) it shows "Preparing BitLocker recovery" and 2) it is asking Choose your keyboard layout. 3) after choosing language, 5) it shows Choose an option. 6) When I choose "Troubleshoot" button, it shows 6 options (1) Startup Repair 2) UEFI Firmware Settings 3) Command Prompt 4) System Restore 5) Uninstall Updates 6) System Image Recovery). When I searched on google, some people recommended "Startup Settings" but in my case there is not such option. I also tried from Command prompt this command `bcdedit /set {default} safeboot minimal` it gave "the boot configuration data store could not be opened." error. I also have my recovery key which I got it from my Microsoft account. But I don't know how to use it and where to type. I need to solve this issue without reinstalling my Windows 10. Any help is appreciated!!

Hi, A,
Sorry to hear you're experiencing this issue.

When you reach the screen "Choose an option" click on "Continue" instead of troubleshooting, this will make your computer boot on Windows and then you will see a screen to enter your recovery key. Once you entered the recovery key your computer should start normally.

In this case, click on Troubleshoot and then click on Startup Repair, your computer will reboot and should let you enter the recovery key.

The Windows partition might be mounted on a different letter, you can use the command "manage-bde -status" to identify on which letter the Windows partition is mounted.

1-Click on Troubleshoot then click on Command Prompt
2-Type this command to unlock the drive and press Enter:
manage-bde -status
3-You should see a screen like in the image below, you need to check which partition has the "Conversion Status" as "Encrypted"
4-Then you need to replace the C: on this command for the letter identified in the previous step and the command again.
manage-bde -unlock C: -RecoveryPassword YOUR-BITLOCKER-RECOVERY-KEY

If you can't identify on which letter the Windows partition is mounted, attach a screenshot of the result of the command "manage-bde -status".
