title: 'vagrant up' not working on Windows
body: <p>I am trying to use Vagrant via Git Bash to download the Linux OS and start up the virtual machine on Windows 7. I have already run the command <code>vagrant init hashicorp/precise32</code> which places the 'vagrantfile' in the destination folder.</p>
  
  <p>The problem starts when I run the command <code>vagrant up</code>. I get the following on the Git Bash :</p>
