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? Oct 2, 2020 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.

    @David Anderson thanks for the help, went through bootcamp assistant and it installed fine on internal drive.

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.
