Just a copy of the files will not boot. It has to be written to the disk as a bootable “ISO image”. Do you have 7 or 10?
I have Windows 10.
But what went wrong during the download process? I put a fresh DVD into my disk tray and clicked on one of the US download sites.
A window popped up asking whether I want to open the file or save it. I chose save, thinking it would copy the files to the disk, but it saved them to my computer instead.
What did I do wrong?
