    you need to boot the windows boot media in UEFI mode. Use the boot menu during start up (I think it is F10)

    Will I have to reinstall my OS for this to work?
  4. You don't.
    Download and install the "DiscWizard V13", when you run the program and you can use the full 3TB. Check the youtube I posted.
