Maybe a silly question but isnt it possible to be able to boot into both operating systems without having to do all kinds of things to get it working?
I have also had difficulties getting LL to boot after i installed a second os (Mint, openuse, manjaro). I am also not really an expert on linux, just got the booting fixed by installing grub customizer on the latest installed linux version and fixing the boot problem using that. Now i dont even dare to install a second os anymore because everytime i removed the second os i was unable to boot into LL and had to reinstall all again.
