May be you have meet these problem with BitLocker: can't start BitLocker program from Start menu, or can't find the BitLocker Driver Encryption in Windows 10 Control Panel, or even you are unable to access the encrypted drive.

Why does BitLocker Driver Encryption cannot Start in Your Computer

Part 1: Your computer operation system does not support for BitLocker.

BitLocker is available on Windows 10 Pro, Enterprise and Education editions. If you are running Windows 10 Home, you won't be able to. You can view what version of Windows you have installed.

Part 2: Some drives cannot be encrypted with BitLocker

The reasons of a drive cannot be encrypted include insufficient disk size, an incompatible file system, if the drive is a dynamic disk, or a drive is designated as the system partition. By default, the system drive or system partition is hidden from display.

Part 3: If your computer is boot in Safe Mode, you cann't start BitLocker program.

BitLocker functionality is unavailable in Safe Mode. BitLocker-protected drives can be unlocked and decrypted by using the BitLocker Drive Encryption Control Panel item. But right-clicking to access BitLocker options from Windows Explorer is not available in Safe Mode.

Part 4: Your Computer doesn't have a Compatible TPM

BitLocker supports TPM version 1.2 or higher. If your PC can't start BitLocker, it's possible that your PC can't meet its requirements:

1. Have at least two partitions:

  • a system partition which contains the files needed to start your PC and the volume must be at least 100 MB.
  • an operating system partition which contains Windows. 

2. Have a BIOS that's compatible with TPM or supports USB devices during PC startup.

To find out if your PC has a TPM:

Step 1: Open Control Panel, click System and Security, then select BitLocker Drive Encryption.

Step 2: On the right-lower corner, click onTPM Administration. Then you’ll see if your system has TPM.

Tip: Good news is that you can configure to use BitLocker on an operating system drive without a TPM as long as the computer is not running a Home version of Windows.
