Background information: so, I had Ventoy installed on Zorin. Don't know how it happened, but when I took it off, for whatever reason the OS disappeared. I snapshoted with Timeshift, but it's not allowing me to load the backup through live, so I decided to just completely start anew.
To the new problem: I reinstalled Zorin. I chose to completely wipe everything off the PC. When I loaded into the OS, though, apparently I still have data from my last install? It's telling me it's full.
Guys, I'm so frustrated with this. I don't know how to even address the problems; I thought reinstalling a fresh OS would be the best fix because it's only needing to reconfigure stuff, but how can I even do that if there's 0 room to even work around? Until I can figure out what the problem is, I'll have to just stick with my old PC for now.
