Removing the last kernel to use the prior one

I all

In my previous topic you can see I had problems with the sound driver

I’m booting with every time I turn on my PC

well, I installed mainline package (as subjected in update ubuntu kernel 20.04) to manage kernel info, this is my list

I was wondering what could happen if I remove (the last one)

I don’t try it right away in case I f***p again

thanks for the comments :grinning:
