    Legacy boot with TPM and autoboot? DE7.1


      I'm trying to enable TPM autoboot on a test pc and the log contiunes to report the same error:


      2014-06-20 15:08:54,963 ERROR   SystemAutoboot                       Could not enable TPM for Autoboot at this time, and it is mandatory in policy.

      2014-06-20 15:08:54,964 ERROR   SystemAutoboot                       Mandatory TPM Autoboot policy can only be enabled after at least one restart following activation, as the boot sequence through pre-boot has to be measured.

      2014-06-20 15:08:54,964 ERROR   SystemAutoboot                       Please restart the system and authenticate through pre-boot to enable mandatory TPM Autoboot.



      Is this only supported with a UEFI boot?  Can I not utilize the TPM hardware and autoboot in Legacy bios boot?  I've deployed Bitlocker using TPM and legacy boot so I was assuming I could.


      Things I've tried:

      Enable TPM in bios

      TPM mmc to activate in windows

      Rebooting numerous times in between all remediation steps

      Much thanks!
