https://www.raspberrypi.org/downloads/ has a new feature. You can download an image code for Linux, Windows, and Mac. I tried the Linux version and it works like a charm. I am using Cent distro (Deb based). It allows a simple select the OS like Rasbian or Ubuntu. Other choices are there too. Here is a screenshot after finishing the write/verify.
Give it a spin and see what you think.
