Is the only option to edit an install to complete reinstall it?

SO for a bit of background, I managed to get my asus g731gu working with a dual boot on my second HDD, partitioning that HDD to have a games section and the MAC drive. It runs fine, but wifi, bluetooth, and trackpad are the three main things that don't function. I'm not exactly sure why, but there's a bigger issue that I don't know if there's a way to edit this within the install, or I have to make all edits on the USB drive then reinstall in order to fix this. For context, the trackpad works in the usb's initial menu, but stops upon entering macos or the recovery dmg. I doubt that has any bearing on my issues, but figured I'd include it on the slim possibility that it does.
