Installing windows on a new machine with a Mac

Brothers and sisters, I've been trying to solve my problems for hours with minimal progress.

I finally completed my first build and am stoked to finally see it reach its potential but I'm stuck at installing windows. I have a 16 gig thumb drive and want to use it to boot windows from, but all I have is a Mac to create the right files and im stuck.

I've googled the issue and there are 60 different directions to go. Please, I need some good directions to get up and running!

Edit: I wasted the entire day and gave up. I just had to find a friend with a windows computer.
