A quote from the article:
During the recording of the Ubuntu Podcast this week Ubuntu MATE's Martin Wimpress mentioned a tool he used to create a bootable Windows 10 USB on Ubuntu.How to Create a Bootable Windows 10 USB on Ubuntu @ OMG! Ubuntu!
I rarely make use of Windows 10 myself but I know that, every now and then, you might need to. And should you need to make a bootable Windows USB I?m sure you?d rather do it on your Ubuntu or Linux desktop.
Now, before we go on, be aware that the method I present in this post is just one of several ways to go about this. I's probably the easiest way to make a bootable USB of Windows 10 that actually boots, but I?m not saying that it's the only way.
