I\'ve installed docker and followed the directions here: https://docs.docker.com/installation/windows/#installation but when I run boot2docker start this happens:
Its worth noting I had some huge problems trying to run docker on windows. Boot2docker would install OK with VritualBox 4.3.20. I could NOT run boot2docker or docker itself.
It took me ages to figure out that I had uninstall VirtualBox 4.3.20 and use 4.3.12 instead which worked first time like a treat!
So.. for Windows boot2docker only use VirtualBox 4.3.12.
