The following commands install the WoeUSB program used to create a bootable USB stick for the installation of Windows 10.
First add the repository (assuming Ubuntu or Linux Mint OS)
sudo add-apt-repository ppa:nilarimogard/webupd8
sudo apt-get update
sudo apt-get install woeusb
The WoeUSB GUI can be found in your Applications Menu but I don’t recommend it. The likelihood is, you’ll run into the problem described here
Using gparted, create a NTFS partition on your USB stick – you may need to install ntfs-tools from your repository to do this.
Create the USB stick using the following command
sudo umount /dev/sdb1
sudo woesub –target-filesystem NTFS –device Win10_1809Oct_EnglishInternational_x64.iso /dev/sdb
