Creating a bootable Windows 10 installation USB drive

The easieset way to create a bootable installation media (USB drive) for Windows 10 (or any other Operating Systems) is using UNetbootin (a free open-source software). It can run on Mac OSes, Windows, and Linux.

I downloaded and installed UNetbootin on my MacBook Air (running macOS Big Sur) and used it to create a bootable Windows 10 installation USB drive successfully. It had two options for writing the Windows 10 setup file to the USB stick: automatically downloading Windows 10 and using local ISO file of Windows 10. I tried it with my MacBook Pro, and it did boot up from that USB. 

Step 1:

Open Terminal and run the following command to see the device identifier of the USB partition for storing Windows 10 installation file (which can be downloaded for free from Microsoft's website).

> diskutil list


For my case, I named the USB parition as REPAIRWIN10 and then the assigned identifier was disk2s6.

Step 2:

Start UNetbootin application and configure it as followings:
