i have used bitlocker using the TPM on my new Alienware 17 r3 but it is not quite behaving and wondered if anyone was using it and had some suggestions.

I have encrypted the OS and the other internal drives and using a PIN as extra security.

The main problem is tht it generally won't boot saying the TPM is not found and needs the recovery password. The bios says there is a TPM, it is enabled so there should be zero reason for it not to be there from what I understand. Once I enter the recovery key, quite often it stops on the Alienware logo,  unless I first go into the bios and then reset, even then it cannot see the SSDs

I have replaced the main PM951 with a 950 Pro which is now the main OS drive and the PM951 is the second SSD. I am also for the most part not seeing these in the bios so wondering if this has something to do with it? One booted Windows behaves fine

The bios is the 1.2.8 version, I am head there might be some issues with this version but it seems I cannot roll it back as no other are available for download

Any thoughts appreciated
