I have a Windows Server 2019 application server running as a VM on a physical Hyper V Dell server. The VM has two partitions. An OS and a data. I added Bitlocker in the app server via server manager roles and features. I enabled TPM on the VM at the HyperV level. I rebooted and it shows bitlocker options in control panel. It only shows the OS drive as available. WHen i turn on bitlocker for it I get a message stating that this drive cannot be encrypted. get - tpm shows that tpm is present and enabled. When I get -bitlockervolume it says that it does not have an associated bitlocker volume. What am I missing?

Windows Server 2019
Windows Server 2019
A Microsoft server operating system that supports enterprise-level management updated to data storage.

    Hello

    What is the error code for Bitlocker unable to encrypt the drive?

    When you enable encryption, you must specify a volume, either by its drive letter or by its BitLocker volume object. You must also establish a key protector. BitLocker uses a key protector to encrypt the volume encryption key. When a user accesses a BitLocker encrypted drive, such as when starting a computer, BitLocker requests the relevant key protector.For example, the user can enter a PIN or provide a USB drive that contains a key. BitLocker decrypts the encryption key and uses it to read data from the drive.

    You can get help from the following documents:

    Thank you. The error is simply "this drive cannot be encrypted". Also, only the OS drive appears when I am in manage bitlocker.
