My work around for this is to load a live usb, unflagged the EFI partion used for MS (remove boot/esp flags). Proceed to install, and reflag the MS EFI partition afterwards. Works a treat, and keeps my installs separate. Another option, is to run windows or linux as a guest VM. You can setup a near native quest VM with device passthrough, such that you only ever have to boot your host OS but can drop down into a fully fledged guest when needed. I'm doing both as methods as a way to slowly offload from windows to linux
