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.

  • Purging Nvidia drives depends on how they were installed. But in this situation I suggest booting a live session, backup what you need and install from scratch, much faster (and with expected better results) than troubleshooting a failed online upgrade. – user692175 Oct 25 '17 at 0:20
  • @MichaelBay yeah i'll probably do that , thanks anyways – George Oct 25 '17 at 10:08

I managed to overcome this by purging the nvidia drivers. I followed the instructions from this post.
