This post is for my own benefit more than anything. I frequently have to ‘google’ for the instructions to make a bootable USB drive to install some version of Windows from. So, to save time in the future, here are the instructions :
Open a command prompt As Administrator. Run diskpart. Enter list disk – this will list all the attached disks, make note of the USB drive disk number (2 in my case, so substitute 2 in the commands below for whatever number it shows on your system :- 
- select disk 2
- clean
- create partition primary
- select partition 1
- active
- format fs=fat32
- assign
- exit
