title: How to create bootable GUI programs?
body: <p><code>*"for Retro computing purposes only"*</code></p>
  
  <p>Some programs are directly bootable and have a nice GUI </p>
  
  <p>e.g. Acronis OS Selector and Disk Director <a href="http://www.whatsabyte.com/images/Dual%20Boot/dualboot12.jpg" rel="nofollow">(screenshot)</a></p>
  
  <p>How can they run wihtout underlying OS? Can this be acheived by using a minimal Linux distribution?</p>
  
  <p>goal: the program should run such that it appears independent of the os (e.g you dont have to launch it from the os cmd or desktop)</p>
  
  <p>also the OS should not have increase the size of the program <em>a bit too much</em></p>
  
  <p>Also I wonder if Qt GUI's can run like this...</p>
