WoeUSB hasn't been very reliable for me. I've had better results booting up a Windows VM to use Rufus with USB passthrough to the drive instead.

I'm love/hating this idea because now I want to burn a LiveUSB running Linux with a QEMU Windows VM already set up on it. I can run it live and have Windows 10 "PE" or I can install it to a host and have Windows up and running fairly smoothly without going through the OOBE.

IIRC you used to be able to make a bootable Windows stick on Linux simply by extracting the contents of the ISO onto a USB stick and marking it bootable. Is that still possible now that EFI is everywhere?
