title: Cannot start docker after installation on Windows
body: <p>I am a new to Docker. After the installation of Docker Toolbox (OS: Windows 10) I run Docker Quickstart Terminal and in the console I see this:</p>
  
  <pre><code>Running pre-create checks...
  Error wirh pre-create check: "Hyper-V is installed. VirtualBox won't boot a 64bits VM when Hyper-V is activated. It it's installed but deactivated, you can use --virtualbox-no-vtx-check to try anyways"
  Look like something went wrong in step 'Checking if machine default exists'...
  Press any key to continue...
  </code></pre>
  
  <p>What did I do wrong? All checking of system and install steps are taken from <a href="https://docs.docker.com/windows/step_one/" rel="noreferrer">here</a>. </p>
  
  <p>Thank you very much for your help!</p>
