A complete disk encryption feature designed by Microsoft, the BitLocker Drive Encryption provides full protection to your data by providing an encryption for your important data. Well, if you wish to use this BitLocker Drive encryption system with your Trusted Platform Module (TPM) for securing your computer’s operating system drive, there are certain requirements that you should meet with. Well, most primarily it is extremely essential that your computer includes a well suited BIOS. If in case the BitLocker Drive encryption and the TPM system fail to work together with your BIOS and the TPM security hardware, then you should immediately contact your hardware manufacturer for the related troubleshooting details and its particular configuration.

The BitLocker Drive encryption also helps you by protecting the operating system drive of your computers without a suitable TPM based security hardware. However, in such cases, you being the user should insert the BitLocker start-up key into your computer using a flash drive. But, this should be done before you start your computer. How to activate the Bitlocker without the TPM security? Well, in order to make use of your BitLocker without the TPM security hardware, it is extremely essential that your computer BIOS supports the USB Flash drive processing in its initial startup process.

When you start up this BitLocker Drive encryption settings wizard in your computers operating system drive through the Windows Explorer or the Control Panel, by default the system checks for the most compatible TPM before it follows any step for enabling the BitLocker feature. However, in order to implement this exclusive feature in your computers without the appropriate TPM, you should first modify the current require additional authentication at startup Group Policy setting. Also, you should choose the Allow BitLocker option without selecting the check box for compatible TPM. As a result of this, the BitLocker Drive encryption system will then make use of the key information that is stored in your USB drive for encrypting all the content stored into the particular drive. Once the drive is properly encrypted based on this method, you should then insert your USB key into the computer every time it is started. This will help you to validate that you are authorized to access all the content stored in this protected drive.

However, if you are using the BitLocker Drive encryption on your computer for successfully running the Windows Server 2008 or perhaps the Windows Vista, you should also enable the desired require additional authentication at startup Group Policy setting. This is necessary for configuring the startup methods for all the computers. Also, when you enable the BitLocker for the first time and before the drive is encrypted, the Bitlocker feature setup wizard provides you the chance to check the availability of your USB flash drive in the initial starting process. In case the BIOS does not support the particular functionality, you will not be able to encrypt the desired drive. However, you can follow the other methods for protecting the content in your drive.
