Repurposing empty partition with Kali

Hello

I currently run Ubuntu and Windows 10 on my machine. A while ago I reinstalled Ubuntu and it has left a 150GB empty partition that I would quite like to use. I'm very interested in installing Kali in it.

What would be the implications of triple booting OSs, in particularly with Kali?

Is there anything I would need to do differently or watch out for? Obviously a full system backup before I fiddle around with anything.

I'm looking for any advice, caveat and feedback on whether or not this is not just doable but advisable.

Thanks!

Just like you dual boot ubuntu. Install kali in the same way.
