title: VirtualBox: "A disk read error occurred" after migrating Win XP to Virtualbox
body: <p>I attempted to migrate an old Win XP Compaq desktop to VirtualBox (4.2.12) under Ubuntu (12.04.1) by following <a href="https://www.virtualbox.org/wiki/Migrate_Windows" rel="nofollow">https://www.virtualbox.org/wiki/Migrate_Windows</a></p>
  
  <p>After the createfromraw step, I created the virtual machine, and tried to boot.  Immediately on boot, this message is displayed:</p>
  
  <pre><code>A disk read error occurred
  Press Ctrl Alt Del to restart
  </code></pre>
  
  <p>I have tried to use FIXBMR and FIXBOOT from the recovery console, which seemed to make it worse (a few characters on the screen are corrupted, and the same error message appears).</p>
  
  <p>How can I get this VM to boot?</p>
