title: dos boot before win7 boot
body: <p>I've got a question for dos &amp; win7 boot process.</p>
  
  <p>Is it possible that dos boot and execute some dos-app before win7 boot without reboot?
  I mean boot process like win95 or win3.1.</p>
  
  <p>I'll explain more detail.</p>
  
  <ol>
  <li>dos boot -></li>
  <li>execute some dos app  -> </li>
  <li>cleanup memory -> </li>
  <li>load win7 volume boot record into memory 7c00 -> </li>
  <li>win7 boot without reboot</li>
  </ol>
  
  <p>Is this possible?</p>
