How do I install Archlinux and Hackintosh on my laptop, without destroying my ccurrent Deepin OS [closed]

I have Deepin OS, and I want to try Arch Linux and Hackintosh without destroying my current OS… How do I do that?

I followed Deepin OS Beta instructions (while installing), and it formatted my current files.. So, don’t wanna make the same mistake again. (note I’m currently on Deepin OS stable)

Please note my current file system:
I don’t know how to manage all that file system stuff with multiple OSes!
