WinUSB

Install WinUSB fork in Ubuntu or Linux Mint

To add the PPA and install WinUSB, use the following commands:

sudo add-apt-repository ppa:nilarimogard/webupd8

sudo apt update

sudo apt install winusb

WinUSB is a tool that can be used to create a bootable USB Windows installer from an ISO or a DVD, either using a GUI or from the command line.

The application looks pretty much abandoned, with the latest release dating back to 2013 however, GitHub user slacka forked it, fixed most of its bugs, and updated it to support both wxWidgets 2 and 3.

I should add that I only tested the WinUSB fork with Windows 10 on Ubuntu 16.04, but it should work with Windows 7 and Windows 8 / 8.1 (and older Ubuntu versions) as well. Also, I performed the Windows 10 installation in VirtualBox, and not on real hardware.
