PXE boot with Secureboot question

Sorry to butt in but we are also having the same issues. I can PXE boot with secureboot on and UEFI and we use MDT.

When it goes through the task sequence it installs the drivers just fine. But when it gets to the OS deployment, it intalls and as soon as it goes to the next phase it Fails and says the following:

I think your issue is different than what is being discussed in this thread.  Looks like you're having some problem with your MDT task sequence.  You should post to some Microsoft MDT forum or else ask for help on our enterprise client management forum here:  https://forums.lenovo.com/t5/Enterprise-Client-Management/bd-p/sa01_eg

@omena,

 

Can you confirm that the Format and Partition (UEFI) is being used?

Re: PXE boot with Secureboot question

Yes I can confirm it is working correctly. As a test, I change my TS to format as MBR and everything boots correct and works. When I change to GPT it goes through the TS and fails at the point after the OS is installed. I am also on the same boat as OP as I am wanting to get away from sophos and want to use bitlocker to encrypt. So I make sure it's on secure boot but it will fail as I have stated

Re: PXE boot with Secureboot question

What model are you using?  If it is from the Tx70 series, what is the actual MTM of the device.  To get this, use:

 

WMIC CSProduct Get Name

What happens if, in the BIOS, under the Restart tab, you set OS Optimized defaults to Enabled, Load the Defaults, and restart the computer and try to deploy again via MDT?

Re: PXE boot with Secureboot question


Any update on this? I have updated everything from my ADK to MDT, Drivers, and sideloaded WINPE drivers for the Boot image just to make sure. Now my imaging of Windows 7 for the same model 20JNS2KA00 might be broken.
