My mom died when I was 20 and the old man sold the house and took off with anything of value while I was just out of electrical engineering and there was a big economic downturn in the early 90s … I crashed on people’s couches in crack house neighborhoods and sometimes slept under bridges or highway overpasses… Had no car - no job and lucked into a job at Sears selling PC’s back when windows 3.11 was king. I earned enough to buy a bike and bike my way to work from wherever I was crashing and bought a damned pink barbie backpack from a tag sale for 2 bucks so I could bring my suit jacket and tie required in those days and I took a damned ribbing until I could get a better situation. People that have a fallback are lucky as hell and should consider themselves so.

Clone your drive first and then no matter what happens you have a quick click to restore. I’ve run dual boots on multiple distros for years and you learn a whole lot when things go wrong.
