I got a new lenovo PC pre installed with windows 8.1 and I'm having trouble installing Ubuntu. I tried using the Live USB/DVD option. It would show an option to choose between windows 8 & Ubuntu and when I choose Ubuntu it will show me an error screen. I didn't want persist because I don't want to screw it up, it being new and all.
What steps should I follow to properly install Ubuntu safely and smoothly?
Thanks!
