When I boot my computer none of the dispay options pull up and I can't even open a terminal using Ctl+Alt+T. When I try to boot it in recovery mode it the same thing happens. I don't get the normal option menu that comes in recovery mode. I was trying to upgrade to 16.04 and halfway through the upgrade my computer turned off, that's when this started happening.

  • I also get a message in the recovery mode that it failed to start Load Kernel Modules. – Caleb Davis Dec 4 '16 at 21:37
  • Turn off secure boot in your BIOS to fix the kernel loading error message. Can you get to the GRUB menu? Can you get to the login screen? Exactly what do you see? – heynnema Dec 4 '16 at 23:08
  • I get the grub menu and the login screen is normal, just as always, but after I log in, there's just a blank screen and nothing but the background – Caleb Davis Dec 5 '16 at 0:31

step #1

  • turn off secure boot in your BIOS, to fix "kernel module load" errors.
  • boot to the GRUB menu
  • choose Advanced Options
  • choose Recovery mode
  • choose dpkg - fix broken packages
  • let it try to finish the aborted upgrade

If that doesn't resolve your problem, I'll give you a different set of specific commands to execute. Report back.

step #2 (detail pending)

sudo apt-get update

dpkg --configure -a

apt-get install -f
  • In the grub command screen when I enter that code it says "can't find command dpkg". – Caleb Davis Dec 5 '16 at 3:15
  • Also, I don't seem to be able to disable secure boot – Caleb Davis Dec 5 '16 at 3:15
  • Like I said, I don't get the normal advanced options. All it gives me is the option to boot in recovery mode or normal and recovery mode doesn't do anything. – Caleb Davis Dec 5 '16 at 3:25
  • Secure boot is a function of the BIOS, and happens long before even the GRUB menu, so the setting has got to be there somewhere. If you have a tabbed BIOS interface, look for a security tab. What happens if you choose a recovery mode for a prior kernel? Does it give you a normal full recovery menu of options, to include dpkg and root? What happens if you just try to boot normally but into a prior kernel? I'm looking for some options here. If we can't get to anything, you may just have to reinstall Ubuntu. – heynnema Dec 5 '16 at 5:18
  • I know where the secure boot is, but for some reason it isn't giving me the option to turn it on or off, it just has it enabled and won't let me change it. As far as kernels go, I only have one option. The only one that shows up is Linux 4.2.0-38-generic and the recovery mode for that – Caleb Davis Dec 5 '16 at 16:33
