If that is a warning (as opposed to error) message saying something
along the lines of "note that with this setup you won't be able to boot
your current system anymore", then that isn't an actual problem. A user
who is planning to replace a system shouldn't be worried about the
installer warning them that they can't boot the (to be replaced) old
system anymore, and can safely ignore that message.
