BitLocker is a Microsoft encryption utility, which encrypts a hard disk drive’s data. Recently, users have complained that they are getting an error message that reads BitLocker could not be enabled the data drive specified is not set to automatically unlock.

It is enabled by default on computers that are running newer versions of Windows, but you can install Windows without BitLocker. If you’ve come across this error, let’s look at why it occurs and how to fix it.

Why is my BitLocker not working?

If you’re having trouble enabling BitLocker on your Windows device, below are some possible reasons:

  • Hardware issues – If you try to enable BitLocker using a computer that does not recognize it, it’s possible that the computer does not have the requisite storage capacity or drivers present on its system. 
  • Bad BIOS settings – If your BIOS settings are not correct, it could prevent BitLocker from working properly. 
  • Unsupported TPM – If your computer is running an earlier version of Windows and you want to use BitLocker, you need to upgrade to TPM 2.0 motherboards.
  • Incompatible partition style – Between the two partitions: MBR and GPT, MBR has less support for features and may not work well with newer versions of Windows.
  • Outdated BIOS – If your BIOS has not been updated in a long time, it may not support newer versions of BitLocker. You need to update your BIOS.
  • Disabled TPM and secure boot – If the TPM is disabled or if the secure boot feature is disabled, BitLocker will be unable to protect your operating system volume.

Before you try any of the below troubleshooting options, check off the following:

1. Enable the BitLocker services
