            How to Create Windows 10 Bootable USB on Ubuntu or any Linux desktop

            Are you looking for any desktop application on Ubuntu to create a bootable pendrive/flash drive with Windows.

            WoeUSB is a simple tool that enable you to create your own usb stick windows installer from an iso image or a real DVD.

            WoeUSB  package contains two programs:
            • woeusb: A command-line utility that enables you to create your own bootable Windows installation USB storage device from an existing Windows Installation disc or disk image
            • woeusbgui: A GUI wrapper of woeusb based on WxWidgets

            So, lets know how install the WoeUSB on Ubuntu 
            Official & updated Installation and Github link : Here
            #    sudo add-apt-repository ppa:nilarimogard/webupd8
            #    sudo apt update
            #    sudo apt install woeusb
            In case if you wish to remove that woeusb PPA, remove it from the bellow command.
            #    sudo add-apt-repository --remove ppa:nilarimogard/webupd8
            #    sudo apt-update
            Now, WoeUSB has installed on my Ubuntu, though the interface is self explanatory still let's move ahead and know how to use it.

            Open WoeUSB application and choose the USB drive and your windows iso kept within your Ubuntu.
            Once you are done click install and you are done, you can monitor the progress on screen.

            In case you receive a error dialogue like below, follow the below steps

            Find your USB drive's mounted file system and block by running lsblk on terminal and find your device their.
            To filter, look for size of your USB or name of the USB drive, below screen shot gives the picture of my USB drive ( 8 GB ) size, and named as /dev/sdc
            #    lsblk

            So we will unmount that partition out of the system.
            Notice there  /dev/sdc is the full size of my USB disk, but the data is witten on it's /dev/sdc1 partition.
            My USB disk is  /dev/sdc, ensure your USB is unmounted with the following command. Replace /dev/sdc1 with your own partition name.
            #    sudo umount /dev/sdc1
            Now try again from the   WoeUSB desktop application.
            In case if you are willing to do the same through woeusb CLI utility, here is the way.
            #    sudo woeusb -v --device /home/kunal/windows-10.iso /dev/sdc
            /home/kunal/windows-10.iso  :  Replace it with your iso location.
            /dev/sdc : replace it with your USB drive ( check it from lsblk )
