That sounds extremely infuriating! Regarding Lenovo and Linux Mint, I actually had a very good experience with them a little over a year ago. I bought a new IdeaCentre 5i pre-built desktop tower and had zero issues installing Mint on it. All I had to do was press F12 and select to boot from the bootable USB to install, no screwing with the BIOS or anything. But I’ve never tried installing Linux on a laptop. I only use desktops.
