Really especially at the my teenage times, there was no Google to help you, no mentors to guide you. You got some shitty homemade linux distro nobody ever heard of on CD from a friend and only way was through trial and error. Funny times

My personal hurdle as teenager always was having to keep windows on same disk for my sisters to use while struggling to install Linux besides it so I could have that semi transparent terminal like in the movies. Can't even count how many times I've bricked bootloader because of that, but when it worked I felt like I'm a president

What does it even mean?

I don't know now but years ago when I used to use windows you wouldn't be able to uninstall it
