How to help someone install Linux?

What are some things to know / keep in mind when helping someone install Linux?

Installing for myself, I have to deal with my choices (like my recent "update without the recommended backup hoping my files are there when I get back", Pop!_OS 24.04 COSMIC). But for others, I'dn't like risking them facing my consequences.

Any tips are welcome!

Edit: for context, I was asked for help on that. I am not converting someone just outta nowhere.

And my worry is less with everyday usage. They can adapt, or, assuming dual boot, boot back to Windows. But we prolly need to choose a distro, and not brick their laptop. Two important parts!

Also, we in CS, so… make of that what you will
