I don't know if it's possible, but have you considered trying to install Windows in a virtual machine and just use Linux as your primary system? I started out this way too, where I had a dual-boot Linux and Windows system, and eventually I realized that I was booting into Windows so little that I just installed Windows in a virtual machine for the, like, very few times I ever needed it. And then, eventually I found out I didn't need it at all anymore, and just killed the VM, and I haven't used Windows for years.
