title: "Disk not formatted" warning after writing bootloader
body: <p>I recently wrote a simple bootloader in assembly for floppy disk booting.  I used 'debug' command on my Windows XP virtual machine, to write on the first sector of floppy disk image.  It works, which is good. Now, I am trying to load the second stage bootloader (or kernel) into the memory by reading sectors: I wrote the second stage bootloader to be read as well as modified first stage bootloader.</p>
  
  <p>To make this happen, I need to copy the second stage bootloader into the floppy disk. I clicked the A: icon on the windows explorer, trying to copy it, but the message I got was "The disk in drive A: is not formatted.  Do you want to format it now?"  At this stage, I got some questions in a row.</p>
  
  <p>My questions are:</p>
  
  <ol>
  <li><p>How do I make windows acknowledge the bootloader I wrote, so that I can copy other files in? (Or is it even possible?)</p></li>
  <li><p>If this is not an option, do I always need to use either "debug" or "partcopy" to copy all other files into the disk?</p></li>
  <li><p>Can I copy the second stage and/or other files into any empty sectors?</p></li>
  <li><p>Debug command is gone in Windows 7 and partcopy windows version didn't allow me to write on the first sector of the disk.  What are the alternatives? (Trying to avoid working on VM.)</p></li>
  </ol>
  
  <p>I am sorry for asking so many question on one thread.  I thought it was easy to ask in one, cause they are all related.</p>
