Windows 10: I have been trying to unlock the bitlock by entering the recovery key but the system...

I have been trying to unlock the bitlock by entering the recovery key but the system returns me back to the bitlock screen. How do I restart my laptop?

Windows BitLocker Recovery Key Not Working (Failed to unlock with this recovery key)

We have a system with BitLocker Enabled. The system requested a recovery key and we entered the correct 48-digit recovery password based on the provided Recovery Key ID. However, after entering the recovery key, it says "Failed to unlock with this recovery key" may I know how to solve the issue and how we get the file on the disk if the recovery is not working?

 

Unlocking Bitlocker encrypted system drive without recovery key

A few months ago I encrypted the whole hard drive on my Lenovo X1 Carbon 3rd Gen notebook. There are no partitions. I did not save the recovery key externally, if at all I saved it then it is on the encrypted drive itself.

Today my notebook crashed (whilst updating iTunes) and during restart I see the error message that Windows has a startup problem. It goes through the auto-repair procedure, which fails, and I'm taken to a screen which asks for my Bitlocker recovery key.
I don't have that so I try the various advanced options like system repair, but none of the options that do not wipe my data seem to work because they need access to the encrypted drive.

1. Is there any way to unlock the drive, given that I know my Bitlocker password but not my Bitlocker recovery key? I am not able to actually get to any screen which asks for the password, every screen is asking for the recovery key.

I tried the command prompt option and entered 'manage-bde -unlock c: -password' which prompts for the password. I enter the password but get the response 'The password you entered failed to unlock the drive'. I'm sure it's the right password. Next I try
to view the recovery key with 'manage-bde -protectors -get c: -type recoverykey' but the resulting data shows the key ID but not the actual numeric key value (it's just blank).

2. Can anything be done to unlock the drive via the command prompt, or any other route such as a boot disk?

3. Is it possible to generate the numeric recovery key elsewhere if the key ID and the password are known?

4. If I remove the hard drive from this laptop and attach it to another computer as a slave drive, is it possible to unlock it there using the Bitlocker password?

 

BitLocker recovery keys after Dual Boot

Hi Varun Kelkar,



Welcome to Microsoft Community. I'm Mosken, let me help you.



According to your description, I knew that you were asked to enter the Bitlocker recovery key when dual booting Windows 11 with Windows + Linux. Is that right?

According to your description and the current situation, you may have used Bitlocker to encrypt the Windows system partition, but after you install the Linux system, the original system partition state has been changed, so you will be asked to enter the recovery key.



Generally, you will be prompted to save the recovery key when you encrypt with Bitlocker, as shown in the figure below.

• If you choose "Save to your Microsoft account", then it will exist in the Microsoft account you logged in when encrypting.
  

• If you choose the other three, it should be a .txt file with a long name contains alphanumerics, please recall whether and where you have saved it.
  

If you can't find the recovery key in your Microsoft account or the file that included the recovery key, I suggest you try unlocking the partition in Linux, back up your data, and then format the partition.

If it cannot be unlocked, sorry, there is currently no other effective solution to unlock a partition encrypted with Bitlocker, you can only reformat the partition to use it normally again.

The above steps are provided based on the information I have learned so far, and hope that could help you a little. If the problem still exists, please provide us a full PSR from the beginning, through the whole process, and until the error message is displayed, so we can further investigate.
