Regardless of bending the narrative to suit your needs, they couldn’t come up with any other top achievement, a water park hardly seems like an achievement for a country, I wouldn’t even be impressed for one of the microstates.

I am unfamiliar with refind, but from my experience with systemd & grub dual boot, if you do not change your boot order in bios, there is a high chance that the windows boot manager will brick your Linux one, even across drives. My advice for dual booting is to ditch the convenience of using one boot manager. But once again, this may not be an issue you have.
