Cannot Boot Ubuntu - Cannot Install GRUB


Greetings:

I was attempting to install some packages and update my Ubuntu system. I tried using both the terminal and Synaptic GUI, but received errors about processing some packages (I did not pay that close of attention because I did not think it was anything serious).

I decided to reboot my system to see if that would help. I was greeted with a message similar to "unable to mount fs on uknown block(0,0)" and unable to boot my system. I thought I might be able to repair it using the Boot Repair utility. I ran the terminal commands instructed by the program and was (apparently) able to remove GRUB. However, now when I try to run the commands to reinstall GRUB, I receive the following error:

Code:
lubuntu@lubuntu:~$ sudo chroot "/mnt/boot-sav/sda5" dpkg --configure -a
dpkg: dependency problems prevent configuration of linux-image-extra-4.10.0-35-generic:

Errors were encountered while processing:
 linux-image-extra-4.10.0-35-generic
 linux-image-generic
 linux-generic
So I tried
Code:
  sudo chroot "/mnt/boot-sav/sda5" apt-get install linux-image-4.10.0-35-generic
The output from this seemed to indicate that I needed to install linux-headers-4.10.0-32-generic. However, when I tried that I received the following:

One possible reason is that you have a incorrect listing in your /etc/fstab file. Which would explain the following message;

Code:
unable to mount fs on uknown block(0,0)
And/or in your GRUB configuration file.

Can you post the following (using CODE tags):
  • /etc/fstab
  • /boot/grub2/grub.cfg

Also, your partitioning?

Since I cannot boot into problem system (sda5), I am not sure how to access the files directly. This data comes from the Boot Repair utility. Please let me know if any other data might help.

Thanks.

As far as post #2 asking you to list /boot/grub/grub.cfg, one method is to boot Systemrescuecd and mount /dev/sda5 at /mnt. Then you can obtain a copy of grub.cfg.

Thanks. I could not find the grub.cfg file (or even the grub directory for that matter). Running "ls" in /boot outputs the following:

Code:
abi-4.10.0-33-generic		       memtest86+.bin
abi-4.10.0-35-generic		       memtest86+.elf
config-4.10.0-33-generic	       memtest86+_multiboot.bin
config-4.10.0-35-generic	       System.map-4.10.0-33-generic
grub.bak			       System.map-4.10.0-35-generic
initrd.img-4.10.0-30-generic.old-dkms  vmlinuz-4.10.0-33-generic
initrd.img-4.10.0-32-generic.old-dkms  vmlinuz-4.10.0-35-generic
initrd.img-4.10.0-33-generic
I did run some commands instructed by the Boot Repair utility to remove grub (with the intent of reinstalling it I suppose). The removal succeeded apparently; the installation did not. So now it seems as if I do not have grub properly configured; I now receive an error message relating to grub rather than the initial mounting error when attempting to boot the problematic OS. Running the install commands:

Code:
udo chroot "/mnt/boot-sav/sda5" dpkg --configure -a
sudo chroot "/mnt/boot-sav/sda5" apt-get install -fy
sudo chroot "/mnt/boot-sav/sda5" apt-get install -y --force-yes grub-pc
Results in (in part) the errors noted above.

Thanks again.

This is a long shot. After booting systemrescuecd, try chrooting using the following:
Code:
mkdir -p /mnt/repair
mount /dev/sda5 /mnt/repair
mount -t proc none /mnt/repair/proc
mount -o bind /dev /mnt/repair/dev
mount -o bind /dev/pts /mnt/repair/dev/pts
mount -o bind /sys /mnt/repair/sys
chroot /mnt/repair /bin/bash
source /etc/profile
The idea is to try and restore the missing grub directory and modules from a chrooted environment.
Code:
apt-get install --reinstall grub
update-grub
If the MBR is hosed, you may have to reinstall the boot loader
Code:
grub-install /dev/sda
If this works, you can try booting ubuntu in single-user mode and continue your repair work. Looks like a lot of your kernel headers and dependencies are missing. There is a way to resolve a catch 22 in debian. Unfortunately, I don't remember!
If this doesn't work, then I am not sure what next.

Assuming that it is only GRUB that is missing and your system is otherwise ok, another way you can reinstall GRUB is to;

First download the Super Grub Disk, burn it on to a CD/DVD (or install it onto a USB stick) and start your Ubuntu installation from it.

And then you can follow the instructions here, to re-install GRUB. (under "The terminal way")

Let us know how you go...
