A month or so ago, I bought a Dell laptop with Ubuntu 16.04 pre-installed. I then installed Kubuntu 16.04.2 side-by-side and have been able to choose either OS via the GRUB screen: I could see the entry that would let me boot into Kubuntu by default, that is, by pressing enter or waiting for 10 sec or, if I wanted, I could arrow-down to Ubuntu.
I keep both systems fully upgraded by running sudo apt-get update and sudo apt-get dist-upgrade.
Today, when I started my laptop, there was no GRUB screen and the system booted directly into Ubuntu, not Kubuntu as it usually would via the GRUB screen.
I thought that I could "fix" the issue by commenting out
in /etc/default/grub, running sudo sudo update-grub, and restarting.
However,on restart, although the GRUB screen appeared, there was no entry for Kubuntu.
This what I see with
As far as I know, the kernel version for Kubuntu is 4.10. I think the 4.12 lines were from when I installed 4.12 to troubleshoot some wifi issue on Ubuntu.
So it looks like entries for Kubuntu are missing entirely
Can someone please help me? I guess you may need more information which I'll do my best to provide.
Thanks!
