    Your wrong! YOU can install with this download, from this disc;that, it was put(burned) onto! BUT…I can not get my system to boot–from this download(burned) disc…no matter what I do.(So far)

      Good evening Joseph.

      The article is not wrong, however your BIOS settings are wrong. It does not allow you to boot from a disc. You have two options.

      A) When your system boots check if a message appears “Press XXXX for the Boot Menu” and then select DVD-Rom
      B) When your system boots look for a message saying “Press XXX for Setup” press that key and find Boot Settings then set the DVD-Rom as first boot device.

      Be careful changing BIOS Settings could render your system unusable.

      Let me know if it helps
      Yuri

    Thank you for the suggestion. Since my previous comment, I reinstalled Win 10, and now, dual boot works. Not sure what happened the first time around. Reinstalling was inconvenient but worked. Thanks again.

    Since this method does not work with Vista and 10, is there another way?

      Caleb, You could use a Virtual Machine to run Windows 10. Such as VMWare, VirtualBox and so on.
