It’s not possible to dd a Windows ISO to a USB stick.

What way too many people fail to understand, because Linux ISOs are applying this method, but this is essentially a MAJOR HACK CALLED ‘ISOHYBRID’, is that, in most cases, you cannot simply take an ISO image and copy it byte for byte to a USB drive, and expect that to boot.
