How to use OSX to create a bootable USB key to install Windows 8.1 on a PC I have a PC laptop without OS and I would like to install Windows 8.1 on it.  

How can I prepare a bootable Windows USB key in Yosemite?  

I have to use OSX to prepare the bootable USB Key, as I have no Windows machine to create it on.
Is it possible? How can I do it?

I saw this post: Creating A Bootable USB Of Windows 8.1 On OS X?
but here the final destination seems another Mac.
Have I to follow the same procedure?
Quick shot:


Download and install VirtualBox
Create a new Windows VM with your Windows 8.1.iso (x64)
Copy the Windows 8.1.iso (x64) to your VM (network sharing)
Download and install Rufus
Plug in your thumb drive and attach it to the VM
Create a bootable thumb drive with Rufus. You may even choose UEFI or BIOS.


Not smart but it should work...

I'm searching for a faster way without creating a VM
