Thanks for the post and I have tried to follow, but the TS cannot load any package after the Restart Boot Image part. It failed with 0x80070002 error.
At first, I split the TPM process into Enable TPM and Activate TPM, then the second one won't run as it failed at "Copy CCTK" part, seems error with load package. Then I have combined both today in one script, and then the TS failed at the "Apply Operating System" part where I can loading an unattended xml file from a package.
Any idea, thanks a lot.
