Configuring the policy is very straightforward. There are four categories to configure. I only wanted to encrypt the OS drive so I figured that that I'd just have to configure the Base Setttings and OS Drive Settings categories.
"Failed to enable Silent Encryption. TPM is not available.
Error: BitLocker Drive Encryption detected bootable media (CD or DVD) in the computer. Remove the media and restart the computer before configuring BitLocker".
Remove the bootable media, and restart the device.
"Failed to enable Silent Encryption
Error: BitLocker Encryption cannot be applied to this drive because of conflicting Group Policy settings. When write access to drives not protected by BitLocker is denied, the use of a USB startup key cannot be required. Please have your system administrator resolve these policy conflicts before attempting to enable BitLocker".
