Since you have Secure Boot disabled, the PC SHOULD be able to boot from and read the USB stick.

 

So, my guess is that you did not make a UEFI bootable Windows USB stick.

 

You can do that by downloading the ISO from MS and then using the free RUFUS utility to make a UEFI bootable USB stick.  You can get RUFUS from here:  Rufus - The Official Website (Download, New Releases)
