Make Windows 7 Install USB on Mojave

The USB is not seen as a booting device when I tried to burn ISO to USB using Disk Utility app on Mojave. Any other suggestions available?

Forum: 

Thanks for the suggestion.

Thanks for the suggestion. The WintoUSB option seems running Windows directly from an USB drive. But I want to use the disk to install Windows.

another alternative...

Another alternative would be to create a vertual machine and create the installer from there
