Triple Boot a Mac - Linux Question

[BestPCBuilder2017]

So I've been thinking about triple booting a Mac in the future and I was wondering, if I'm using MBR (Master Boot Record) and install in this order: Mac, Windows, Linux and for the Linux installation I install the bootloader to the Linux partition (for example, let's just use Ubuntu), would I still need another bootloader in order to boot to the Linux partition?

you should be able to boot into the linux partition using your 'macs existing bootloader' on EFI

It's not a Hackintosh though, this is a legit Mac related question.

boot from mac onto your linux partition and it should allow you to select between windows or boot into linux.

Use clover or something to have the choice to boot into GRUB, Windows Boot Loader or just mac os x. At least that's how I do it

I triple-boot my Macbook. This is how:

Installed Windows next to macOS using BootCamp. I then created a third partition for Linux and installed it. Now, when I press Option during boot, I see 1 Macintosh HD option, and 2 Windows options. The bootloader is stupid and thinks anything that is not macOS is Windows. 

Anyways, when booted in macOS, I installed rEFind. 

 

When I boot now, I get the rEFind bootloader first (GUI and boot options are customizable) that shows macOS, Windows and Linux. When I chose Linux I get to Grub where I just configured it to automatically boot Linux after 2 seconds (just to not have to chose linux twice in two different bootloaders).

 

It might not be optimal, but it works perfectly for me.
