The files in the Win10 folder must be copied over to a fat32 formatted usb stick, then booted off this stick via boot override in the bios. It will then give you a factory restored system
Indeed that is what I was assuming at first too. However, this method is also a similar method used to recover on the Surface Tablets too (Format as fat 32 and copy the files across). You may have to change USB boot to UEFI I guess.
