In my experience, Windows only fucks-up your Linux bootloader if they both share the same EFI System Partition. Keeping them separate fixes the issue. Though, this means that you’ll have to install Windows first, since it will automatically pick your Linux ESP otherwise.
Not sure how I managed this but I installed windows long after Linux on my gaming PC (to use a VR headset that was given to me), and somehow it created its own EFI partition without nuking the real one.
