I tried to install win10 to ssd via efi boot on my macbook air 2012, it ran pretty well as far as performance, but because it's pre-uefi it makes it the garbage windows version with no sound, no proper graphics card, can't change brightness, it's awful, then I tried parallels, and I can tell already that it's going to suck how the mouse moves so that's out.

So, my only option is to try a legacy bootcamp partition install somehow sharing the same hdd as my macOS (which has plenty of room and is fast), but this is mostly a novelty thing, I have a windows laptop, so if there's a risk of mangling my mac I'll just get a newer macbook eventually

Is there a way to make an mbr bootcamp partition? if it's doable safely, any resources would be appreciated as I looked online and it's a mess of forum posts of peoples' problems.

  • You question does not make any sense. Explain why you do not just use the Boot Camp Assistant application to install Windows 10 to the internal drive? – David Anderson Oct 2 '20 at 19:50

  • @David Anderson I'm not an expert on the matter, but I think it will cause problems because my macbook air 2012 is pre eufi, and that results in a broken functionality windows discussions.apple.com/thread/250137979?page=15, I tried installing with vm and ssd and both times the graphics card driver update would crash it, no audio, etc, which was fine because that wasn't my internal, but I don't want to mess with my main mac drive and have that ruined, so unless I know it will work differently with bootcamp assistant on the internal drive I'm hesitant to risk it. – GGarrett2 Oct 2 '20 at 20:00

    @David Anderson thanks for the help, went through bootcamp assistant and it installed fine on internal drive. – GGarrett2 Oct 3 '20 at 2:45

Using the boot camp assistant, loading a usb 2.0 usb stick with the iso and drivers, partitioning the drive in boot camp assistant, then letting it reboot into the usb 2.0 installed windows fine on a 2012 macbook air with all windows functionality.

no need to mess around with efi and weird workarounds to get audio and having screwy drivers.
