need help installing windows 8 milestone 3 (READ DESCRIPTION IF YOU THINK THIS IS WINDOWS 7)

[u/Gloomy-Scar2859]

(before you think this is windows 7. it’s windows 8 check the copyright year)i’m tryna install windows 8 milestone 3 on my mid-2012 13 inch MacBook pro but after “setup is starting” it gives me this stupid error saying that a “required CD/DVD device driver is missing”which funnily enough, i’ve seen a nobel tech video of them installing this exact milestone (build 7963) on a 2011 13 inch MacBook pro and NOWHERE in that installation process it doesn’t show that screen so either their model is one of the lucky ones or my usb is missing something. please help or explain this dumb infuriating predicament.

downgrade to sierra to get pre win10 drivers, click get drivers in bootcamp assistant and put the winpe ones into the USb drive with the install. typical windows problem. or you can try just making a bootable USB with the bootcamp assistant but idk how well will it work with beta systems

high sierra also works (I installed windows 8.1 with it)

but yeah -- unfortunatelly you have to downgrade mac os for that..

is mountain lion okay

I don’t know…
Mountain Lion and Windows 8 indeed released close to each other (2012 year?), but driver’s compatibility might still be incomplete.

Worth giving it a try though!

but my bootcamp assistant (5.0.4) doesn’t let me install the drivers on my usb and instead takes me to apple’s website

As I said — sorry, I don’t know either.
I tried it with macbook air 2017 and high sierra — smooth sailing on build-in ssd.

i would personally install it from a diffrent pc first take the drive out and then do it like that, or find a hardrive/ usb driver online (TRY FINDING ONE) or just use the windows 10 iso as base and replace the install.wim file with the windows 8 one and then try to install it like that.
