I used WoeUSB because I was doing it on my other PC which runs Linux.
However I used the same USB to install Windows 10 on my friend's laptop and it worked.
On my PC I used to have Windows 10 running just fine and then I decided to reinstall it (I had had a lot of useless programs and files piling up there so I decided that reinstall would be simpler than cleaning it up).
So i made a bootable Windows 10 USB, the first couple of installation steps...
