Here is my original post:

When I enable Intel Trusted Execution Technology (TXT) in th... - HP Support Community - 8719497

 

The solution:

 

In the BIOS, I had to disable "Native OS Firmware Update Service" under Main --> Update System BIOS.

This had to be done because Windows always updated the BIOS through Windows Update to N21 Ver. 02.62

That new version and N21 Ver. 02. 61 also causes this issue.

So the solution is I had to rollback to N21 Ver. 02.60

I used the "-> Check HP.com for BIOS Updates" under this menu. When the Network BIOS Update page came up, I selected to rollback one-by-one to 02.60. Each time I tried to enable Intel TXT on its corresponding page, it could successfully boot to Windows on 02.60 with Intel TXT enabled. 

It needs further investigation what will happen if I enable "Native OS Firmware Update Service" and let Windows do the update through Windows Update, or if I manually update the BIOS. 

Also I  have to check what are the updates and improvements in those two updates, to know what am I missing now on 02.60

I'll report back if I did that experiment.
