The easiest way is to use Windows inside a VM to create the Windows USB stick.
- Get a Windows 10 ISO image from somewhere.
- Download VirtualBox and create a virtual machine from the ISO image.
- Connect the USB stick with the virtual machine.
- Download rufus and use it to burn the ISO to USB. (Set Partition scheme to MBR)
If you have no Windows 10 ISO image you can use a virtual machine provided by Microsoft. And inside the virtual machine you can use the Windows 10 media creation tool to create a Windows 10 USB stick.
