title: Install Windows 10 on OSX Parallels - Setup Media Driver Missing
body: <p>I got an error whilst installing Windows 10 from .iso file as virtual machine via Parallels 9 on OSX 10.10 which read something like: <code>Media driver missing</code>. It leaves you in a loop which requires you to add the drivers. But you cannot install any cause there are no suggestions.</p>
  
  <p>Now the main issue seemed that the iso wasn't on a bootable device which is what most sources say you need to do. Obviously that seemed like an unneeded step and i got the installation going. Mostly because you were already inside the installation that had been booted in the first place.</p>
  
  <p>Software i use:
  OSX 10.10 (latest)
  Parallels 9 (latest updates, i know Parallels 10 is out)
  Windows 10 iso from <a href="http://preview.windows.com" rel="noreferrer">http://preview.windows.com</a>
  VM setup with iso from external HD (NTFS) and locally stored. </p>
  
  <p>So what to do?</p>
