I created a partition for Elementary OS this weekend and installed it there, I assigned 30GB to it, now I deleted it because I want to try out Linux Mint since many people told me it's better than Elementary, I will assign 60GB to Mint to install VirtualBox on it.

Mint is super light. 30 would be plenty unless you like tons of programs. I can check how much space mine uses later.

I installed mint, I assigned 60 to install VirtualBox and run Kali within it, therefore that's why I used that much because Kali with scripts ~30GB
