When I dual boot Linux and Windows, I like to have two separate drives and not ever mix up the bootloaders. I then use my motherboards boot selector to choose which one, and I leave the main OS as the first priority one.
Works perfectly, avoids Windows overwriting Linux and avoids GRUB breaking for the 11th time this month because it’s a terrible piece of software. The only downside is it takes 10 seconds longer, because whenever I want to change I need to wait for my motherboard to recognize the boot selection key.
