Win + Linux + Hackintosh Triple Boot

Hey guys, so this is my build: https://www.reddit.com/r/hackintosh/comments/88hgx5/help_with_determining_the_compatibility_of_system/

My plan is to dual boot Win + Linux on the m.2 SSD, and have Mac on its own separate SATA SSD.

If I follow this guide: https://www.reddit.com/r/hackintosh/comments/68p1e2/ramblings_of_a_hackintosher_a_sorta_brief_vanilla/

I have a few questions:

• Should I set up my Hackintosh first and then the Win + Linux? Or order not matter?

• Would it be as simple as setting up Hackintosh and then installing Windows + Linux using separate USB drives onto partitions, and clover will pick everything up? Or do I have to do some extra steps to set everything up?

Thank you!
