Ubuntu – Ubuntu 16.04 not booting 4.13.0-x-generic

bootdual-bootgrub2kernelupdates

I was using version 4.10.0-42-generic before and it worked fine. I can still choose it in GRUB but the new versions I got from updates do not work.

The new versions that do not work are 4.13.0-26-generic, 4.13.0-32-generic, neither upstart or recovery mode.

There is no error message or anything when I choose those, it just restarts my computer and I am back in GRUB. I am worried that I will run into problems if I keep use the old version later on. Any ideas on how to fix this?

Kind regards

Ubuntu – Ubuntu reverted to GNU GRUB beta version

What you see looks like a normal GRUB boot menu. The entries listed in the boot menu allow you to select the default Ubuntu kernel or to choose between two Linux kernels 4.4.0-71-generic and 4.4.0-72-generic and boot with the selected kernel. If you use the ↑ and ↓ keys to select the default option marked by an asterisk (Ubuntu (Generic)) and press Enter to boot from it, your computer should boot into Ubuntu with the default kernel as usual.

If you run apt policy grub2-common in Ubuntu 16.04, you should get the following result.

grub2-common:
  Installed: 2.02~beta2-36ubuntu3.9
  Candidate: 2.02~beta2-36ubuntu3.9

It shows the same result as this first line on the GRUB menu screen in your question, and everything on your GRUB screen is normal like it should be including the Advanced options for selecting options of booting from different recently installed Linux kernel versions.

If you run uname -a the results should show that you are using the 4.4.0-72-generic Linux kernel, which is the latest version in Ubuntu 16.04, the same as is shown in your GRUB menu screen.

Regarding the GRUB menu screen, normally you do not see this screen, and what specific GRUB screen you see depends on whether your system is a single boot or dual boot.
