By something strange, I assume you mean installing Windows on a disk with the other disks disconnected so Windows will create its EFI partition on that disk (since it’s dumb and will create EFI partition on the first disk it finds, even if it’s an HDD). Though UEFI doesn’t mind, will still list all the bootloaders from different disks without any problems. You can even unplug and plug them as you wish, it still won’t be corrupted this way.
