Hi.

On my PC, encryption option doesn't show up in setting. But I managed to find bitlocker in control panel.
On my try, Bitlocker can encrypt all the drives except drive C.
Drive D (share the same NVMe SSD with drive C), Drive F (2TB HDD), drive G (3 TB HDD), drive H (4TB HDD) it's all fine.
But not with drive C. I don't know what preventing it from applying the encryption.

What shows when you click the link at the bottom for "requirements"? Have you verified that your C drive meets those listed requirements?

Probably you can enable Bitlocker on the system drive via Global Policies

Computer Configuration - Administrative Templates - Windows Components - BitLocker Drive Encryption -. Operating System Drives - Require additional authentication at startup

(I had to do the same on a W7 system without TPM)
