I usually just carry around a few ISOs with Ventoy. More specifically, a Win10 ISO, Ubuntu ISO, Arch ISO, Tails (not iso but who cares), and a few others that I wanna be able to install if I ruin my current system to the point I can’t boot it properly. I just noticed I still need a Fedora ISO. After watching the LTT video too, I’m looking into all of those cool utilities too, don’t have any recommendations yet tho.
