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.
It's certainly not, there are other iso to USB drive tools for Linux. But the only way to make a Windows To Go USB from Linux is with rufus on a Windows VM with USB passthrough.
