Ubuntu Installation :: Failure To Load Following Kernel Upgrade
Feb 6, 2010
I successfully installed Ubuntu 9.10 Netbook Remix on an Asus EeePC in a dual boot mode with Windows XP. Because the computer has no CD drive, I used a USB stick to download the files for installation. Twice now, after upgrading to a new kernel (2.6.31-17 and 2.6.31-19 I think), when rebooting after the upgrade and selecting Ubuntu from the operating system menu, I get a message:
sh:grub>
along with a notice about limited shell commands being available. The ls command results in:
(loop0) (hd0,3) (hd0,2) (hd0,1)
In trying some of the other commands, I get a message that a linux kernel isn't loaded. The computer still runs Windows fine - or at least as fine as Windows ever runs. I'd like to recover Ubuntu without doing another full installation.

I'm running the 64 bit version of Ubuntu 9.10 on an AMD64 dual core platform with all the most recent upgrades installed. After the most recent Kernel upgrade version 2.6.31.20 the computer failed to boot correctly. Extremely slow getting to the desktop and a general failure to preload any programs that I load on boot. I had to uninstall and revert back to the previous Linux headers which solved the problem. If it makes any difference I have the machine setup as an apache2 server along with my standard desktop environment.

I've been running Ubuntu 10.04 AMD64 on our home theater PC through a wubi installation. Yesterday the system update installed a new kernel and today there is a problem booting the computer so I'm reluctantly using Windoze to type this. there isn't much information: the computer has always booted fine before the kernel update. When I select Ubuntu in the boot menu the screen goes black and the computer restarts. No error messages, no GRUB menu, just a blank screen before restart.

I learned yesterday that doing a massive upgrade on my system while moving was a BAAAD idea.The upgrade process was going along just fine, it was all downloaded and was actually installing that last time I saw it. I unplugged my laptop to move a bookcase out, and completely forgot to plug it back in. After I got back from moving a load, I found my computer was off. I tried to boot up, and I got an error that kind of freaked me out. It reads as follows:
Code:kernel panic not syncing vfs unable to mount root fs on unknown-block(0,0)I'm able to get to grub just fine, and my windows partition loads up just fine, but any of the linux kernels fail similarly when I attempt to load them.I'm sure that I can fix this, I just have no idea how. Probably has something to do with a live cd.

Over the past few days I have been trying to install an older kernel (kernel 2.6.28.1) on ubuntu 9.10 64-bit WUBI installation. I compiled, installed, and updated my grub for the kernel. When I reboot, the grub menu correctly gives me the option of booting into the older kernel but when I do so I receive the following error message:
error: you need to load the linux kernel first.
I am at a complete loss on how to fix this. I even downgraded grub but I still get the same error.

Computer won't startup after upgrade from Ubuntu 9 to 10.04 Lucid.
Upgrade performed through Update Manager.
Have repeated this exercise with the same result. (After failed first time, reinstalled v9 successfully. Waited a few weeks then tried updating to v10 again. Same unsuccesful result as last time I tried it.)
Got one error message during upgrade: "Missing resoureces. The Network Manager Applet could not find some required resources. It cannot continue."
Upgrade otherwise appeared to operate smoothly.
But:
When upgrade complete, and on restart, the following happens:
Gets to purple start-up screen fine. The dots tick away for a little while, the hard drive accesses, then goes to blank screen and all stops. Nothing. Keyboard doesn't work. Screen backlit, but no-one's home.
Restart again makes no differnce.

I was running Ubuntu 10.10 and I was having issues with graphics card drivers so I decided to try upgrading to Natty using my Internet. The download went fine, the installation went fine (I sat and watched the computer the whole time. When I tried to upgrade from 10.04 to 10.10 I had the same issue and ended up having to wipe my hard drive and start over from the CD). But right before the installation was finished, the screen went blank except for a tiny text-editing cursor and even the cursor froze. Also, the Caps Lock and the Num Lock lights were flashing in sync rapidly. After a while I forced it to shutdown and then restarted it. GRUB boots, giving me a list and the option to go to a command line, but if I select 2.6.38-8-generic or the recovery mode, it freezes and the lights flash as described above.
In other words, all I can get to is a very basic CLI through GRUB.

Upgraded from 10.10 on my tower (scratch built, AMD Phenom II X6 1090T 3.2GHz, 16 GB RAM, 2x Sapphire Radeon HD6870 1GB) and it seems to have gone very wrong.
At the final post-installation reboot I get BIOS post, a black screen that hangs around alarmingly long, then the Ubuntu splash screen, then another black screen that seems, if anything, even MORE black (don't know how that works, but that's how it looks - it's not OFF but it's VERY black) and a whole lot of nothing going on.
Tried Ctrl-Alt-F1 to get to a TTY session, no go, no reaction. Just my friendly black screen. Tried F2-F6 as well, same deal. Tried Ctrl-Alt-F7 through F12 on spec, also no response. So Control-SysRq-K... and I DO get a response - I get a black screen with a number in []s and SysRQ: SAK. No TTY. Still doesn't like Ctrl-Alt-F1.
No disk thrashing. Nothing but gently whirring fans and my error message.
-UPDATE I take it back, it finally gave me a TTY login.
So. Um. Any guesses what happened to my poor XWindows setup?

After a kernel update ubuntu would not boot. So found this procedure using the live update cd. Update grub.cfg & delete everything down to but not including the first line that starts with 'menuentry' . Then boot works ok. A couple of weeks ago it started on my notebook. Is anyone @ hq listening & able to fix this problem permanently?

I ran the upgrade from ubuntu 9.10 yesterday and it's now a mess. Is there something I can do to refloat this ship?
The file download stage seemed to be working OK: I was watching it when it only had three minutes left to go. I went away and came back a few minutes later and the screen had gone black. OK I thought, this must be all part of the plan, so I went away and came back over an hour later: still nothing. I decided, perhaps foolishly, to press the power button and boot it up.
Eek! Now I get the following errors:
mounting none on dev failed: no such device
chroot:cannot execute /etc/apparmor/initramfs: no such file or directory
Then the message Ubuntu 10.04 LTS cruncher tty1 and a login prompt. I can log in OK but don't know what to do next to recover the situation.
Rather alarmingly there is some activity on the system: lots of messages beginning with a number like [22.71309.

I was happily running 10.04--- really worked fantastically! Then, I updated all, and upgraded to 10.10 using the upgrade manager in Ubuntu Desktop. Now, when I choose Ubuntu from the boot page, the computer shuts down--- no errors, it just reboots and I get right back to the boot page. I cannot boot into Ubuntu at all, and I am now stuck with Windows 7 once again.

I'm having a few problems getting my system to boot after upgrading to 11.04.This problem actually first arose when I upgraded from 9.10 to 10.04 a couple of weeks ago, however I found I was able to boot by loading a selecting a previous kernel version (2.6.31.22 was the latest version I could successful boot from) and as I was a bit busy with exams at the time I decided to leave it be temporarily as I at least had a functioning system.I upgraded from 10.04 to 10.10 and then finally to 11.04 today. The original problem persisted on the upgrade to 10.10 however I was at that point still able to boot using the older kernel version. On the restart after the upgrade to 11.04 however, the system now freezes when trying to boot from 2.6.31.22 or previous versions (the splash screen shows and then the system gets stuck on a blank screen with just a cursor visible, but remains responsive to mouse (cursor moves) and keyboard (goes into restart process on Ctrl-Alt-Del)).
I'm at a bit of a loss of what to do and would be massively grateful if anyone had any advice of where to start for a solution. I can access the system using a LiveCD - the output of the boot info script is attached.

I was updating the kernel and left the computer to let it do its business. There was power failure and I don't know if the update completed or if it was in the middle of it. Now if I start the computer, it freezes up at the login screen. I tried to recover from grub, by selecting "Ubuntu, with Linux 2.6.32-21-generic (recovery mode)". There were no prompts for input after this. The recovery screen is not updating anything after:
[2.348886] EXT4-fs (sda1): INFO: recovery required on readonly filesystem
[2.349015] EXT4-fs (sda1): write access will be enabled during recovery
[2.577641] EXT4-fs (sda1): recovery complete
[2.578072] EXT4-fs (sda1): mounted filesystem with ordered data mode
Begin: Running /scripts/local-bottom ...
Done.
Done.
Begin: Running /scripts/init-bottom ...
Done.
When I come out of that screen (ctrl-alt-del), the problem repeats.

I have 3 separate hard drives, I IDE and 2 SATA. The IDE has side by side installation of Windows XP and Ubuntu. The 2 sata drives each have Ubuntu only. I upgraded the 2 separate drives to 10.04. with no problems I then upgraded the dual boot Ubuntu to 10.04 and it would no longer boot I formatted the partition and did a clean install of 10.04 Thereafter the Ubuntu on the dual boot drive will boot but windows will not nor will either of the 2 separate drives. Results text from boot info search is attached. I can access the 2 Ubuntu drives through the funcitonal Ubuntu on the dual boot drive, but cannot boot them.

Running 10.04 tried to upgrade to 10.10. Download ran for 6.5 hours then produced a failure message. Download speed varied all over the place from 30 kbps to 170 kbps but usually well below 100. Speedtest shows about 100 kbps in and out. Is there a way to drop back to 10.04 ad run the 10.10 download from scratch? Attempts to run the download now produce index error messages.

1. Update-manager panel icon changes into do-not-enter traffic sign.
2. If you want to re-install Update-manager using Synaptic, then Synaptic opens for a while and then closes by itself.

I recently realised that I could use Linux to "revive" old machines, and have set it as my goal to actually get all old PCs in my house working again using different variants of Ubuntu, while learning how to use the OS in the process.And now I got stuck while installing the OS on an old Laptop. It's an HP Omnibook XE-3, with a Pentium III 1066 MHz cpu and, supposedly, 256 MB of RAM. However, for some reason the computer only reads 248 MB, so I've been forced to resort to an alternative disc installation. Since the old HP has a broken CD tray, I've been using an external hard drive to boot the image, created with Ubuntu's startup disk creator, instead of an actual CD rom (I doubt that makes a difference, but just in case)
There are two main issues which have really left me with no obvious (for a newbie) alternatives. Firstly, when the text installation procedure reaches the "Installing base system" part, an error message appears saying that no kernel could be found on my Drive, so the installation fails. If I try to skip installing a kernel temporarily, it lags horribly and produces multiple errors, dying shortly after.The second problem is that I can't actually do a command line boot to try and manually figure out a way around this. Selecting the command line installation mode on the main installation menu changes nothing, and it's a normal text install which runs instead.Unable to access the command line,why my kernel is apparently missing.

I,ve tried upgrade from F14 to F15 using preupgrade, but I run into serious problem. Preupgrade downloaded all packages without problem and prompt me to reboot. After reboot installation process went ok. It was upgrading cca 1650 packages. But installation hung around package 1600 (almost on end) with message that openjpeg-devel-1.4-6.fc15.i686 cannot be installed and only option to end installer. After reboot I ended up with "kernel panic - not syncing: VFS: unable to mount root fs on unknown-block(0,0)". It is still possible to enter grub menu, where I can choose upgrade to F15, but it fails again on that openjpeg-devel package. When I enter terminal after failure, I can see package is downloaded in preupgrade repo (and after moving somewhere else and running upgrade again it I got message that package is missing). Is there any possibility to skip this package installation or only option is fresh reinstall?

The laptop I regularly use is out of use after having tried to upgrade from ext3 to ext4, following the instructions that can be found at namely, Step 2: Upgrading to Ext4Well, the first step was done without problems, but when I reached "Mount your filesystem", the problems started:When typingsudo mount -t ext4 /dev/XXXX /mntwhat appears is:UNEXPECTED INCONSISTENCY; RUN fsck MANUALLYStupid me, I did nothin but jump to the next step:gksu gedit /mnt/etc/fstabWhere I only got a fully white screen with no written text at all, instead of the menu that should have appeared, as can be seen on that webpage.
However, after running Gparted again, it showed the extension as EXT4, not EXT3, so I thought the system had automatically upgraded. Then I proceeded to boot the system, and this is where the massive failure appearedAfter seeing the Ubuntu logo for a while, the system directs me to a blank screen with the message:Mount of filesystem failed.dc5123-ec01-4438-8bd6-cb85bb080f87A maintenance shell will now be started.CONTROL-D will terminate this shell and re-try.root@hihihi-laptop:#So I type CTRL-D:

I moved from 8.04.2 to 10.04.2 and tried to upgrade from GRUB Legacy to Grub2. I must have made a mis-step somewhere in the process as on boot it now tells me
Code:
GRUB Loading stage1.5.
GRUB Loading,
Error 15
_
Is there a nuke from orbit, no finesse way of just ripping all the existing GRUB mess out and installing GRUB2 from Boot disk? for instance should I be just be able to boot with a LIVE CD mount the primary disk of this machine and enter the below in a terminal without messing up any further?
Code:
sudo grub-install --root-directory=/media/PRIMARY_DISK /dev/sda
