I've been trying (since I have a pack of 100 DVD+Rs) to burn Windows 10 to one and install it on my laptop. However, whenever I try, it just boots as normal and doesn't consider the DVD ROM a boot device. Previously I used a DVD-R to install Windows 8.
I have the order set in the BIOS to be Disc > Hard Drive > Network
, but it still doesn't recognize it. I’m using the official “Technical Preview ISO,” and burning it with the Windows 8.1 built-in disc burner (right-click ISO, burn disc image).
Does this mean it’s impossible to use a DVD+R (rather than a DVD-R) as an install disc for an OS? Is this instead an issue with the Windows 10 ISO? I tried again with Ubuntu on a disc from the same pack, but it, too, was ignored.
