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 Outdated BIOS – If your BIOS has not been updated in a long time, it may not support newer versions of BitLocker.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.

How can I fix the BitLocker could not be enabled error?

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

Ensure you check for any Windows updates. Check whether your PC meets the Windows 11 system requirements. Disable BitLocker and enable it again.

1. Enable the BitLocker services

2. Reinstall TPM drivers 

This method will only work if your PC already meets the system requirements for running Windows 11. TPM 2.0 is one of the prerequisites so if the drivers are outdated, reinstalling them might solve the issue of unsupported TPM.

3. Update BIOS

4. Disable TPM temporarily

Remember that you can also enable BitLocker without TPM especially if you’re operating an older system that doesn’t meet modern PC system requirements. SPONSORED

5. Convert your partition style

When you do the conversion, any data on that drive will disappear so ensure that you back up all your files before performing this step. Also, if you’re successful and can now enable BitLocker, BitLocker may fail to encrypt your hard drive.
