title: Get drive letter of Hard drive
body: <p>My application is for windows Vista and XP. </p>
  
  <p>There are more than on Hard drive connected to my machine. I need to get Drive Letters of the Hard drive from which my system is booting. </p>
  
  <p>By using GetLogicalDriveStrings Function I can get the drive letters of all Hard drives. But how can I differentiate that this particular drive letter is the partition name of my booting Hard drive?</p>
  
  <p>The structure of disks are:</p>
  
  <p>disk0(Booting with this)- C D G</p>
  
  <p>disk1- E F H</p>
  
  <p>disk2- I J </p>
  
  <p>I need to get the C,D,G only.</p>
