Use BitLocker on Drives without Trusted Platform Module
Use BitLocker on Drives without Trusted Platform Module
BitLocker is one of the most useful features of Windows 7 which uses a special method of combining hardware and software to protect your hard disk data. Alought it can be available in Ultimate and Enterprise versions of Windows 7 and Vista, it requires a Trusted Platform Module (TPM) on the system at the same time. The problem is that not all systems include TPM. Fortunately, it also have a way to solve it. Just try to bypass it.
Enable BitLocker
Now let's take a look at how to enable BitLocker on a local hard drive.
In order to encrypt an entire drive, just right-click on the drive and click "Turn on BitLocker" from the context menu.
Then you'll need to type a secure password that will be used to access the drive (Just type what you want, but do not forget it. ).
Next you're prompted to store the recovery key which is used when you lose your password or smartcard.
Note: If you choose to store it as a file, make sure that it's not on the same drive which you're encrypting.
Then you can see the progress bar and wait for a while until its completion (The amount of time it takes will vary based on the size and amount of data on the drive. ).
After that, to access the encrypted drive, you'll need to enter the password to unlock it.
Then the drive icon will change to show it's encrypted with BitLocker, where the gold lock indicates it's locked up and the gray lock is displayed after you have unlocked it.
Use BitLocker on a Drive Without TPM
Have you ever got this error? Do you know what's a TPM? Well, TPM stands for Trusted Platform Module which is a microchip in a computer that supports advanced security features. It is where BitLocker stores the encryption key.
If you just have a drive that doesn't have a compatible TMP, you'll have to follow the steps below and have a flash drive.
Firstly, type gpedit.msc in the search box of the Start Menu and hit Enter.
Then under Local Computer Policy navigate to Computer Configuration Administrative Templates Windows Components Bit Locker Drive Encryption Operating System Drives and double click on Require additional authentication at startup.
In the following screen, select "enable" to close the feature and check the box next to "Allow BitLocker without a compatible TPM", click "Apply" and "Ok" to close out of Local Group Policy Editor.
After the configuration above, go back to the hard drive you want to encrypt and turn on BitLocker. A restart will be required to prepare the disk, and check the flash drive is plugged in.

Then select the drive you want to use to store the key.
Now it's done! Maybe this way is not convenient for you to operate, but at least you don't have to go out and buy a new system that includes a TPM.
