Windows 2012 R2 ISO to USB

Need to rebuild my drop-dead Windows 2012 R2 server.
There is no way to burn the 5.4GB ISO to my single layer 4.7GB DVD media.

So the only way is to USB boot it, here is how.

Format your USB drive - FAT32 ONLY. Make sure it is format with Master Boot Record scheme.
Plug in to your machine

Download your Windows 2012 R2 ISO file

Download Windows 7 USB/DVD Download Tool here

Install Windows 7 USB/DVD Download Tool

Run it and select your ISO and target your USB

Done
