Windows 10: Computer Not Booting After I Enabled TPM and Bitlocker for C Drive

I was trying to encrypt C drive with BitLocker but I was getting error for TPM so I enabled TPM and turn on BitLocker, after the restart my computer is not booting. When I power on I get AD Ready to Boot event code on motherboard and computer turn off after 10-15 seconds.

BitLocker not requiring password at boot. (Without TPM)

I've recently installed bitlocker on my computer. Although windows says my C: drive is encrypted; I am not asked for my decryption password when i boot the computer. I get put straight into the login screen. I've done the necessary steps to enable bitlocker without TPM but maybe i missed something. Help please.

 

Bitlocker vague error message enabling on boot drive

Trying to enable bitlocker on my boot drive:

I have a TPM chip installed and cleared and in the TPM MMC console this shows as ready for use

I have UEFI boot enabled and confirm that msinfo32 shows boot mode as UEFI

I have GPT Partition on my boot disk (I did have to convert this using the mbr2gpt utility)

When I try to enable bitlocker on c: drive it comes back with very unhelpful error "The data is invalid" after doing some checks.

When I try to enable I see in the event log event ID811 from source Bitlocker-API

"BitLocker cannot use Secure Boot for integrity because the required UEFI variable 'PK' is not present."

Any ideas here? This is Windows 10 1709 build

Thanks
