Fix: BitLocker Can't Encrypt the Drive Access Is Denied

BitLocker failed to encrypt the hard drive and prompted "BitLocker cannot encrypt the drive, access is denied"? don’t worry! This article will provide effective solutions to help you successfully encrypt your hard drive.

Problem: BitLocker cannot encrypt the drive, access is denied

BitLocker is a security function that comes with Windows systems. It is used to encrypt the entire volume through TPM technology, effectively reducing the risk of data leakage or loss when the computer is lost or damaged. Even if your operating system drive does not have a TPM, you can still use BitLocker as long as the BIOS or UEFI firmware is able to read the USB flash drive in the boot environment.

However, sometimes you may not be able to encrypt your drive using BitLocker due to an "Access Denied" error. Here is a real case:

I created a custom image for my Dell laptop and everything was installed properly and I could log in without problems. The update runs smoothly. The only problem is that when I log in as a normal user, the C: drive is not able to encrypt it, it prompts me the error message mentioned in the topic: "BitLocker cannot encrypt the drive, access denied".

This problem can cause your private data to be lost or stolen. Therefore, we have gathered several possible solutions to help you fix the "Access Denied" error for BitLocker drives in Windows 10.

How to fix BitLocker's inability to encrypt drive, access denied

Method 1: Start BitLocker Drive Encryption Service

If the BitLocker drive encryption service is disabled, BitLocker may not work properly. Therefore, first you need to make sure that BDESVC is enabled.

Step 1: In the Windows search box, enter "Services", and then click "Services" in the best match result.

Step 2: Locate and double-click "BitLocker Drive Encryption Service". In a new window, select the Automatic option from the Startup Type drop-down menu.

Step 3: Click "Apply" and then click "OK" to make the changes take effect. After that, you can try encrypting the hard drive again and check if the problem is resolved.

Method 2: Check user permissions

If you try to enable, disable, or change the BitLocker configuration on the operating system and on the fixed data drive, you need to be a local administrator group member. Standard users can only enable, disable, or change the BitLocker configuration on removable data drives.

To change the administrator user account type, you can refer to this article: How to Change Administrators in Windows 10? (5 methods)

Method 3: Encrypt the drive using BitLocker alternative

If BitLocker still doesn't work after you try the above solution, you can use third-party file encryption software such as VeraCrypt, TrueCrypt, etc.
