T440s Windows 10 UEFI Secure Boot is it possible?

I'm trying to do a clean install Windows 10 Pro x64 v1703 (Creators Edition) from a UEFI USB flash drive created with Microsoft's Windows Media Creation Tool. It gets to the point of trying to partition Lite-on SSD it gives an error.


BIOS updated to latest version 2.42 3/14/2017.

I've tried to format SSD on another pc w/ diskpart select disk x, clean, convert gpt


Has anyone been able to install Windows 10 with UEFI/Secure Boot enabled / CSM off?


I'm guessing this model doesn't support full UEFI mode for Windows 10?

It should work fine. Choose custom install and delete all partitions and install to empty space
