Troubleshooting BitLocker Setup
If you receive the following error when trying to setup BitLocker, it likely means your computer does not support the Trusted Platform Module (1.2) chip.
You can work around the error by launching Group Policy then make an exception. Press Windows key+R then type: gpedit.msc then hit Enter on your keyboard. Expand Administrative Templates then Windows Components then Bitlocker Drive Encryption then click Operating System Drives.
Right-click Require additional authentication at startup then click Edit.
Choose Enabled and then check the box to allow BitLocker without compatible TPM in the Options section.

Confirm the Changes
Click Start then type: gpforce.exe /update to ensure the changes are applied. I would also recommend you restart your computer after executing this command.
BitLocker might not be for everyone, but for people who work in environments with sensitive data that you travel with, it is recommended. I recommend you invest in a dedicated thumb drive to store your recovery key and also keep a printed copy of the 48 character key just in case you lose either. Also, make sure you create a thorough backup before starting this process. You can never have too many backups of the backup.
Remember that you can encrypt flash and SD drives, too. For more on that read our article: How to Encrypt a USB Flash Drive or SD Card with BitLocker to Go.
