   manage-bde -status
   

   This command will display detailed information about each partition, including its BitLocker protection status. Look for the partition you intend to install Windows on. The “Protection Status” will indicate whether BitLocker is “On” or “Off”.

3. Unlock the Protected Partition: Once you have identified the BitLocker-protected partition, use the following command to unlock it. Replace <partition letter> with the actual drive letter of the encrypted partition and <BitLocker Recovery Key> with your 48-digit BitLocker recovery key.

   manage-bde -unlock <partition letter>: -rp <BitLocker Recovery Key>
   

   For example, if the encrypted partition is drive D and your recovery key is “123456789012345678901234567890123456789012345678”, the command would be:

   manage-bde -unlock D: -rp 123456789012345678901234567890123456789012345678
   

   After entering the command, press Enter. The system will attempt to unlock the specified partition using the provided recovery key.

4. Disable BitLocker Protection: After successfully unlocking the partition, it is crucial to disable BitLocker protection to allow Windows installation to proceed without further interruption. Use the following command, replacing <hard drive partition letter> with the drive letter of the partition you unlocked:

   manage-bde -protectors -disable <hard drive partition letter>:
   

   For drive D, the command would be:

   manage-bde -protectors -disable D:
   

   Press Enter to execute the command. This will temporarily suspend BitLocker protection on the selected partition.

After completing these steps, you should be able to proceed with the Windows installation process on the unlocked and unprotected partition. Once Windows is installed, you can re-enable BitLocker if desired, after the setup is complete.

2] Delete the BitLocker Encrypted Hard Drive Partition¶

If you do not have access to your BitLocker recovery key and do not need to retain the data on the encrypted partition, deleting the partition is a viable solution. This method effectively removes the BitLocker encryption by eliminating the partition itself, allowing you to create a new, unencrypted partition for Windows installation. This approach will result in data loss on the deleted partition.

Deleting Partition During Windows Installation¶

1. Select the Encrypted Partition: On the “Where do you want to install Windows?” screen during the installation process, locate and select the BitLocker encrypted partition that is causing the error. It will typically be marked with a lock icon or indicated as BitLocker encrypted.

2. Delete the Partition: With the encrypted partition selected, click on the Delete option. A confirmation prompt will appear, warning you about data loss.

3. Confirm Partition Deletion: Click OK to confirm the deletion. The selected partition will be removed, and the space will be shown as “Unallocated Space”.

4. Create a New Partition: Select the “Unallocated Space” that you just created. Click on New to create a new partition in this space. You can specify the size of the new partition or use the entire unallocated space.

5. Activate the Partition: After creating the new partition, ensure it is selected, and then click Next. Windows Setup will format the new partition and begin the installation process on this unencrypted space.

By deleting the BitLocker encrypted partition, you bypass the encryption barrier, allowing you to install Windows on a fresh, unencrypted partition. Remember that this method permanently erases all data on the deleted partition.

3] Clean the BitLocker Encrypted Hard Drive Partition Using Command Prompt¶

If deleting the partition through the Windows installation interface does not resolve the issue, or if you prefer a more forceful method, cleaning the drive using the diskpart utility in the Command Prompt is an effective alternative. This method completely wipes the drive, removing all partitions and data, including BitLocker encryption. This is a more drastic approach and should be used with caution, as it results in irreversible data loss on the target drive.

Using Diskpart to Clean the Drive¶

1. Access Command Prompt: As before, on the Windows installation screen, press Shift + F10 to open the Command Prompt.

2. Launch Diskpart Utility: Type diskpart in the Command Prompt and press Enter. This will launch the Diskpart command-line utility, a powerful tool for managing disks and partitions.

3. List Available Disks: To identify the disk you want to clean, type list disk and press Enter. Diskpart will display a list of all available disks in your system, numbered starting from 0. Identify the disk number that corresponds to the drive you want to clean. Be extremely careful to select the correct disk number to avoid data loss on the wrong drive. You can usually identify the correct disk by its size.

4. Select the Target Disk: Once you have identified the correct disk number, select it using the command select disk #, replacing # with the disk number you identified in the previous step. For example, if the target disk is Disk 0, the command would be select disk 0. Press Enter to execute the command. Diskpart will confirm that the disk is selected.

5. Clean the Disk: To completely wipe the selected disk, type clean and press Enter. This command will remove all partition and volume information from the disk, effectively erasing all data and BitLocker encryption. This action is irreversible and will result in permanent data loss on the selected disk.

6. Create a New Primary Partition: After cleaning the disk, you need to create a new partition to install Windows. Type create partition primary and press Enter. This command creates a primary partition using the available space on the disk.

7. Activate the Partition: To make the newly created partition bootable, type active and press Enter. This command marks the current partition as active.

8. Format the Partition: Format the new partition with the NTFS file system using the command format fs=ntfs quick. This command performs a quick format, preparing the partition for Windows installation. Press Enter to execute the command.

9. Exit Diskpart: Once formatting is complete, type exit and press Enter to exit the Diskpart utility.

10. Exit Command Prompt: Type exit again and press Enter to close the Command Prompt window.

Now you should be able to return to the Windows installation screen, select the newly formatted partition, and proceed with the installation process without the BitLocker error. This method ensures that the drive is completely cleared of any previous encryption and partitions, providing a clean slate for Windows installation.

Understanding BitLocker Recovery and Key Management¶

BitLocker encryption is a robust security feature, and understanding how to manage your recovery keys is crucial to avoid lockout situations and data loss.

How to Unlock BitLocker Encrypted Drive in Windows¶

The primary method to unlock a BitLocker encrypted drive in Windows is by using the correct BitLocker recovery key or password. When BitLocker is initially set up, you are prompted to create a recovery key. You are given options to save this key, such as:

• Saving to your Microsoft Account: This is often the most convenient and recommended option. The recovery key is securely stored in your Microsoft account and can be accessed from any device with internet access.
• Saving to a File: You can save the recovery key to a file, typically a .txt file, and store it on a USB drive or another secure location.
• Printing the Recovery Key: You can print the recovery key and store the paper copy in a safe place.

To unlock a BitLocker drive, you will be prompted to enter either your password or the recovery key if the system detects an unauthorized access attempt or a change in system hardware. If you have forgotten your password or are locked out, the recovery key is your only way to regain access to your encrypted drive and data.

How to Recover a Lost BitLocker Key¶

Recovering a lost BitLocker key can be challenging, and in some cases, impossible. The ease of recovery depends on where you initially chose to store the key.

• Microsoft Account: If you saved your recovery key to your Microsoft account, you can retrieve it by logging into your Microsoft account on another device and searching for “BitLocker keys”. Microsoft provides a web interface to manage and retrieve your stored BitLocker recovery keys. This is generally the easiest and most reliable recovery method.

• File or Printed Key: If you saved the key to a file or printed it, you will need to locate the file or paper copy. If you have misplaced these, recovery becomes significantly more difficult. Thoroughly search all potential storage locations, including USB drives, external hard drives, and secure document storage.

Important Note: If you cannot locate your BitLocker recovery key and you did not save it to your Microsoft account, data recovery from the encrypted drive is generally not possible. BitLocker encryption is designed to be highly secure, and without the correct key, accessing the data is computationally infeasible for most users.

Best Practices for BitLocker Key Management:

• Always save your BitLocker recovery key when enabling BitLocker.
• Utilize the Microsoft Account option for ease of recovery and secure storage.
• Keep a backup copy of your recovery key in a separate secure location, especially if you choose to save it to a file or print it.
• Test your recovery key after initial BitLocker setup to ensure you can successfully unlock the drive in a recovery scenario.

By understanding BitLocker recovery key management and following best practices, you can minimize the risk of permanent data loss due to lockout situations and ensure you can always access your encrypted data when needed.
