Being able to boot back to Windows in a pinch will be beneficial though.
The annoying thing is that this is not possible without sacrificing system stability, there are about half a dozen known issues with windows update removing Linux bootloaders in a dual boot system, and it has personally bricked my system twice even with booting from a separate drive. I would highly recommend making your fallback a VM like qemu or a more well integrated one like winboat, it is just not worth the risk to dual boot.
