i have an Ubuntu system dual booted with Windows10. I want to change Ubuntu with Lubuntu (i don't care about my Ubuntu files), so here is my question: if a launch Lubuntu installer from USB then i erase Ubuntu partition and use empty space to install Lubuntu, would it work without some boot problem? I don't want to have troubles with Grub, that is pretty annoying with dual boot. I try to google for it but i didn't find anything. Any good / bad experience with this?
