I tried to upgrade from 15.10 to 16.04 but my system doesn't boot properly. It got stuck in the rebooting phase and all i get when i boot is this and nothing else.
I tried everything stated here dev/sda1: clean, this message appears after I startup my laptop, then it won't continue booting but nothing.
I also managed to get to the log-in screen (somehow from the recovery mode) but whenever i pressed log-in it flashed some [OK] and some words but i didn't get in.
The only thing that i haven't tried is to purge the nvdia drivers which i don't know how to exactly do.
I've got dual boot and Windows work fine.
