ALERT! /dev/disk/by-uuid/xxxxxxxxx does not exist. Self Inflicted.

I tried oldfreds suggestion

gksudo gedit /etc/grub.d/40_custom

Code:

Code:

menuentry "Test boot " {
    set root=(hd0,1)
        linux /vmlinuz root=/dev/sda5 ro quiet splash
        initrd /initrd.img
}

I have no gui

so I did this in nano, I noticed that sda5 was mounted. Also, the newest kernal still will not get to login during boot: I am using an older kernal that will go through login, and let me use ctrl+alt+F1 .

This did not change anything. BTW, why do we want "quiet splash" when we are debugging?

Now I have to go cut wome firewood -It's cold in California!

I think the reference to older kernel is still in the same version of Ubuntu or versions of 3.13.xx. You should have housecleaned out previous versions of kernels after you have upgraded. They may have other conflicts with the rest of system being newer.

Yes better without quiet splash, I just happened to post a standard entry.

oldfred -
Yes, I am booting Ubuntu 14.04 when I select kernel 3.5.x-x

Also, I forgot to mention that six months ago when I upgraded 12.10 => 13.10 I was greeted with a black screen and a message: ubuntu ext4-fs error (device dm-0): hdtree_dirblock_to_tree:920
Fixed by

Code:

sudo dpkg-reconfigure -a

I will not be surprised if I have to repeat that. But for now I do not have a blank screen, just no Unity.

Can you please comment on my questions at the bottom of #10 in this thread?

You should not need to reinstall desktop as that is the entire GUI system and all the programs.

But you can totally uninstall grub and reinstall it. Boot-Repair can help with that.

Or you can chroot into your system.

Include this when chrooted:

apt-get purge grub grub-pc grub-common
mv /boot/grub /boot/grub_backup
mkdir /boot/grub
apt-get install grub-pc grub-common
grub-install /dev/sda
grub-install --recheck /dev/sda

I continue to work on this problem, even as I spend time trying to get familiar with grub and doing everything from the command line.

gksudo gedit /etc/grub.d/40_custom

Code:

menuentry "Test boot " {
    set root=(hd0,1)
        linux /vmlinuz root=/dev/sda5 ro quiet splash
        initrd /initrd.img
}

The above creates a new menuentry, but when I select it from the grub boot menu, it immediately goes to a gray screen, ctl-alt-del does not even work! I suppose that it is diagnostic, but I don't understand what I have learned. How would I know if the problem is not a typo in the script?

remove quiet splash and perhaps add nomodeset since you have an old nVidia.

With my nVidia cards I always had to use nomodeset until I installed the proprietary nVidia driver. You will need a legacy driver. Which should be in Ubuntu repository. Look in system settings, either drivers with 12.04 or other Software and drivers tab.

Progress? maybe... Update Follows:

I followed the procedure in
drs305 chroot to purge & reinstall grub2
http://ubuntuforums.org/showthread.php?t=1581099

And I didn't see anything unusual when I went through the steps. At the end, when I ran update-grub, I saw the files listed for the 3 kernels that I have in my system.
I rebooted, and now can only get a grub CLI, so back to the 14.04.1 and64 desktop DVD live session to investigate.

I am still trying to use a separate boot partition ( I intend to put two more distros on this system).
I found the familiar files on sda1:

Code:

$ ls /media/ubuntu/4b2a5548-1adb-49a9-a71e-b9cb04fc4f23
abi-3.11.0-22-generic         lost+found

initrd.img-3.13.0-43-generic  vmlinuz-3.5.0-51-generic
initrd.img-3.5.0-51-generic

But I did find a boot partition on sda5, which was not there before.

Code:

sudo ls /media/ubuntu/98b26601-cad0-4df1-9fb3-e9efcdbc1d65/boot
grub  initrd.img-3.13.0-43-generic

I am posting the results of bootinfoscript, hoping it will be useful.

I don't know what to do next, except to look on the forums for solutions to "grub boots to command line interface"

edit Post: tried this from grub CLI

Code:

grub> set root=(hd0,1)

grub> initrd /initrd.img-3.13.0-43-generic
grub> boot

failed

"mount: mounting /def or /root/dev failed : no such file or directory"
"Target filesystem doesn't have requested /sbin/init"
"Try passing init=bootarg"

If you really want separate /boot partitions, you must have one for each install, otherwise you get massive conflicts.

With manual boot better to use links. If you use the specific kernel it is in /boot not /.

Separate /boot on sda1, / on sda5:
grub> set prefix=(hd0,1)/grub
grub> insmod linux
grub> set root=(hd0,5)
grub> linux (hd0,1)/vmlinuz-3.13.0-43-generic root=/dev/sda5 ro
grub> initrd (hd0,1)/initrd.img-3.13.0-43-generic
grub> boot

If you have boot files in a /boot folder in the / , then one update was done without mounting the /boot partition. When you chrooted, did you also mount the /boot?

Better to use this or Boot-Repair's Summary report which also uses this version:
