The dreaded "A required CD/DVD drive device driver is missing".
There are several threads dedicated to this, and so far nothing seems to be working.
Asrock z170 ITXm/ac
Win 7 OEM install DVD purchased from Amazon
LG external USB optical drive
I am only using the USB 2.0 ports
I have tried the following:
Unplugging all devices from USB 3 ports
Unplugging DVD drive for x seconds at install screen, plugging into other ports
Changing BIOS settings:
USB legacy auto
PS2 emu enabled
SATA is not set to RAID
I do not believe there are any other relevant BIOS options.
Inserting (USB2 slot) a FAT32 or NTFS-formatted Kingston thumb drive with various driver .exes (such as SATA drivers and USB drivers). Unfortunately, neither the drivers nor the USB show up
Creating a bootable USB with grub-install:

But this also complains about the driver. Unplugging/replugging the USB does not fix the problem
But to no avail. Note also I do not have a running Windows OS: only Linux and Mac.
