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.

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.
