Hi:

If you have W8 on there now, you can upgrade back to W10 without the need for any installation media as follows...

Click on the blue Update Now button at the link below...

If you want to boot from a disk you first need to go into the BIOS, enable legacy mode and disable secure boot.

See this link for the settings to change, and how to boot from a DVD...
