I'm Greg, an installation specialist and 8 year Windows MVP, here to help you.
To make a bootable disk from an ISO or other bootable file, right click to Burn Disk Image using Windows Image Burner.
If you're creating Windows bootable media, use Media Creation Tool installed from this link which will prompt to burn the disk if you save the ISO: http://windows.microsoft.com/en-us/windows-10/m...
If it's something else and you need more help, just let us know which.
I hope this helps. Feel free to ask back any questions and let us know how it goes. I will keep working with you until it's resolved.
