When I go to BitLocker and click on C: Drive this is what it says: A Compatible Trusted Platform Module (TPM) Security Device must be present on this computer, but a TPM was not found. Please contact your system administrator to enable BitLocker

If your machine has a TPM 1.2 chip you must enable it in BIOS. If you do not have a TPM 1.2 chip in your machine you can use group policies to enable BitLocker using USB memory sticks instead. Please verify if TPM is disabled in BIOS and activate it.
