Can't boot a VM in Hyper-V after enabling TPM. Boots fine, without it enabled

Question

Greetings everyone.

I cannot enable TPM on a Gen 2 VM running Server 2016, on a Hyper-V also running Server 2016. It boots fine, if it is not enabled, but fails, if I enable it, with the following errors:

I am not sure what invalid parameter it is trying to pass. We just enabled TPM on the host and have also enabled secure boot and it is currently encrypted with BL. Our goal is to have all servers encrypted with BitLocker.

Any help would be greatly appreciated.

Hi @James

This error code usually indicates that the bootloader was unable to load the required file. We recommend that you try the following steps to resolve this issue:

1. Make sure your server is eligible to enable TPM.
2. Make sure you have the latest firmware and drivers installed on your server. You can contact the server manufacturer for the latest firmware and drivers.
3. Try disabling the Dynamic Memory option on Hyper-V. You can disable this option by selecting the VM in Hyper-V Manager and clicking Settings > Memory > Dynamic Memory.

Hope it helps.

Kind regards,
