Device Guard BIOS Setting?

T460s and T470s have a Device Guard setting in the BIOS. According to this article (, only ThinkPad devices with this setting are officially supported for Device Guard. However, I would like a more detailed explanation of what the BIOS setting actually does or what feature it enables. We have some older model ThinkPads that meet system requirements for device guard according to Microsoft that do not have the BIOS option for enabling device guard, so we are looking for further information in order to move forward. 


Thanks for any input.

Re: Device Guard BIOS Setting?

I have the same question about this feature, using the X1 extreme; I am worried about the boot order being locked & not being able to use USB Flash to repair / re-install MS OS. For reasons unknown, I cannot place the USB F to the top of the boot order list. Details seem to be scarce on this -even with the instructions!

Re: Device Guard BIOS Setting?

With Device Guard enabled, boot order is locked to internal drive only.  USB boot is not possible.  But you can always go into BIOS setup and disable Device Guard if you need to boot to USB.
