Create Windows Bootable USB with UUByte ISO Editor

If you’re on a Mac running macOS Catalina or even an older version, you’ll need a special utility to burn ISO files to flash drives to create bootable Windows installation media. The built-in Boot Camp Assistant app no longer works on Windows 10 ISO. We recommend UUByte ISO Burner when working with Windows ISO files on Mac. It’s easy to use, offers additional functionality like editing, copying, creating or extracting from ISO, and even first-time users will be comfortable with its very powerful yet highly simplified interface.

Here’s what you need to do after acquiring your Windows ISO file:

  • Install UUByte ISO Editor and launch the application. When you see several options on the home screen, choose Burn. Insert your USB drive at this point.

  • On the next page, select your Windows ISO file and drive letter or drive name corresponding to your USB, and hit the Burn button. You can name the drive in the same window as well. All the setting parameters are configured automatically.
  • Wait for around 10 minutes and a bootable Windows installer is ready for usage. However, don’t let the Mac fall into sleep during the burning process to avoid potential errors.
