I have to disagree about the idiot proof. KDE Plasma and Mate Desktop are more idiot proof and easy for newbies than Windows 10-11, yet have more features in their simple control panels.

I’ve had no bootloader problems in the last 10 years of Debian, Linux Mint, and Ubuntu (15-20 installs, plus another 20-30 if you count VMs.) However, my work computer’s bootloader was semi-bricked twice in 2019 (Windows 7).
