It is non-trivial to setup refind in the OPs setup.
There is a pattern we see around here regularly that is someone has a problem booting and they are told to install refind. More than half the time they end up back here with a system more broken than what they started with.
There is nothing wrong with using refind if you prefer it but asking a someone who is new to Linux to setup a triple boot and reconfigure their install so it works with refind is no simple task.
