I am trying to install Windows 7 on my Computer, but I always get this error ("A required CD/DVD driver is missing").
Motherboard: Gigabyte GA-H170M-DS3H
I tried all kind of stuff already like unplugging the USB-Drive, moving it to another USB-Slot, create a new USB-Drive, installing from a microsoft-original installation cd, but none of this helped...
Any Bios settings, i might be missing?
Strange thing is that a Windows 10 installation a few months ago succeeded without any problems.
Thanks in advance for any help!
