Ubuntu Installation :: Kernel Upgrade Renders Unbootable?

Dec 2, 2010

I did a routine update of my ubuntu 10.4 (in wubi vista) to the latest kernel (something -26) and installed a java plugin for firefox. After a reboot, i open up the "Ubuntu" entry and i see a message flash accross the screen (something about hda,0,0 or sda im not sure) then it just reboots the PC. No command line or anything. No need to say im pretty screwed

My question is, is there any way to get my files off of wubi? Or even better can i restore Ubuntu to working again? P.S for some reason the two times i have tried to run a live CD on this laptop, it has corrupted vista.

Ubuntu :: 9.10 Update Renders System Unbootable?

Nov 22, 2010

My mom's computer is no longer bootable. I was thinking of attempting to fix it later on this week and am thinking of doing a chroot and updating via a live CD hoping that an even newer update solves the problem but I have some doubts of success. Does anyone have any information about this issue so that I can be better prepared to fix it? Also, I thought I should mention that I tried the second newest kernel to see if that would make it work. It didn't. The error is something along the lines of having the /dev/diskuuid change. If I'm correct, Ubuntu changed the disk's name and is trying to boot the old name. It's dropping to an initramfs shell (not the regular terminal where you can work miracles ).

Ubuntu Installation :: Failed Upgrade 9.10 -> 10.04: System Unbootable

May 4, 2010

I've just reported a launchpad bug report about my desktop system being unbootable after upgrade to lucid lynx. [URL]... I opened this thread to ask if someone else experienced a similar problem and for collecting information and workarounds (none yet) about this quite serius problem. The system has an nvidia graphic card and proprietary drivers were installed before the upgrade. However I'm not sure the problem is related to this. FYI, the system booted regularly from a usb stick with ubuntu lucid lynx. SO the problem is in the upgrade path.

Ubuntu Installation :: Upgrade Hung Now System Unbootable

May 4, 2010

I tried running an upgrade from 8.04 LTS to 10.4 last night, and things seemed to be going smoothly. The upgrade progress was nearly complete, and I wandered off for a while to let it run. When I came back, I had nothing but an orange screen and and unresponsive system. I left it alone all night with the hopes that something would happen, but this morning nothing had changed so I hard restarted the system.

Ubuntu 10.4 appears in GRUB, but the system cannot boot and exits with a kernel panic and the message "vfs unable to mount root fs on unknown-block" I was able to boot to a 10.4 LiveCD, and I can browse all of my files from there. What can I do to get this system back up an running? I have dozens of user account and a lot of customization (it acts as a webserver with a wiki for a gaming website running on it, among other things), so I really really don't want to do a fresh install and lose all my data and customizations.

Ubuntu Installation :: Randomly Upgrade Distro Made Windows7 Unbootable

Jun 10, 2010

Suffice to say I had a dual boot at work with an essential windows 7 and non-essential linux install on it, and randomly upgrading the distro made windows7 unbootable. Cue a missed days work, much embarrassment and ear bashing from those who are convinced Linux is written entirely by communists and hippies. In the end I had to re-install windows, which cut off the ability to boot to ubuntu - although I've left the existing ubuntu partitions as they were.

Although I can get away with allocating a few partitions to ubuntu, I can't really justify fiddling with the MBR based upon this experience. I need a fast boot and persistent data for doing anything further with ubuntu at work, so I'm wondering whether a safer bet would be to setup a usb stick with enough grub to boot to the existing ubuntu install? Not a full usb distribution, just enough to boot into the existing install? how this would be doneIs it really just a grub-install /dev/sdXX (where XX is the usb)?

Ubuntu Installation :: 10.04 - Whenever Attempt Upgrade Server Becomes Unbootable And Have To Reimage And Start Again

Apr 18, 2011

I have had Ubuntu desktop on my PC for a year now and am very happy with it. A couple of months ago I got a Ubuntu server 10.04 for playing about with. I have installed the gui, for personal reasons, but I want to upgrade to 10.10

Whenever I attempt the upgrade my server becomes unbootable and I have to reimage and start again. I have even tried performing the upgrade before I install the GUI but it still makes no difference.

Although I have the GUI I am doing the upgrade via command line.

Upon watching the upgrade in process, I find that no errors are occurring. Could it be something to do with my server provider?

Server Specs are: Specification: Intel Dual Core, 2.2 GHz 800MHz FSB, 2MB L2 Cache, 2Gb DDR, 1x 250Gb HDD

Ubuntu Installation :: 9.10 Upgrade To 10.04. Windows 7 Unbootable / After Using "sudo Update-grub"?

May 9, 2010

My current situation is I have two physical hard disks, one with Windows 7 (sda) and another where I recently installed Ubuntu 9.1 (sdb). At this time there were no issues.

Now after getting used to 9.1 I selected to upgrade to 10.04 from the update manager. During this install I was told I needed to upgrade GRUB which I understand is the bootloader and was told to choose where to install it.Now at this time I had no knowledge of drive naming conventions in Linux and there was no option to cancel the upgrade to look for help, so instead I followed the advice in the help box to simply select every device listed

The result was a fully working Ubuntu installation but at the cost of an unbootable Windows 7.Windows is showing on the GRUB menu but selecting it gives only a blank screen with a flashing cursor and no ability to do anything besides ctrl-alt-delete.

After a few hours of googling solutions including downgrading GRUB, there was no change and it seems that I actually have a version of GRUB on both drives. The one on the windows drive (sda) is the default loaded GRUB that shows Windows 7 but cannot boot it. The second GRUB install on the Ubuntu drive (sdb) is the one I am able to configure through Ubuntu but does not list Windows 7 on its boot list even after using "sudo update-grub"

Fedora :: 14 Unbootable After Latest Kernel Update?

May 11, 2011

I have a Macbook Pro 5,5. I had Fedora 14 installed on it, updated to the latest version. I updated the kernel, and performed an update. Now, every time my system starts, it loads up the startup fedora bar, and it gets stuck at the bar being loaded 100%.I press ESC to see what is going on behind the scenes, and I notice that the problem is that atd cannot start up.

Slackware :: Custom Kernel, Now System Is Unbootable?

Jun 26, 2011

I compiled my own custom kernel for the first time. I tinkered with different options, nothing to difficult. I actually didn't expect it to work the first time.

I had kept the original lilo boot config just in case something was to go wrong. Now when I try to boot the system, I always get a "VFS: cannot mount root system on (8,3)". I googled this and found that my kernel did not support my root filesystem (btrfs). So I made an initrd with btrfs kernel module, but it didn't help. I then got a string of errors about how /dev could not be mounted.

My question is two-fold. First, how come when I configure the system back to when it was first installed, it still won't boot? Im using the same kernel (2.6.37.6-smp). Second, how can I get myself out of this rut without reinstalling?

lilo.conf

Code:
lba32
append=" vt.default_utf8=0"
boot=/dev/sda
vga = normal
# Linux - Slackware
image = /boot/vmlinuz-huge-smp-2.6.37.6-smp
root = /dev/sda3
label = Linux
read-only

BTW, I have been maintenancing the system by chrooting into the device off of my slackware boot disk. Im on slack 13.37

Ubuntu Installation :: 10.4->10.10 Renders System Unusable?

Sep 29, 2010

After doing the standard sequence to go from 10.4 to 10.10 beta, the system is now unusable.There are no icons and no thees. The GDM login shows a big question mark where a graphics would normally be.When I log into the session, I get nothing: no desktop, no panels. Alt+F2 does nothing, so I can't even launch a terminal that way.After starting a terminal from a virtual console, I can start looking at what's wrong. Metacity crashes right awaywith:metacity:ERROR:ui/ui.c:752:meta_ui_get_default_window_icon: assertion failed: (default_icon)Aborted (core dumped)

Ubuntu Installation :: 9.10 Makes Unbootable USB Stick?

Apr 23, 2010

I have a 4 gig Kingston USB stick. I have an Eee PC with 4 gig internal flash drive (no hard drive). I can't find the specs but I believe it is roughly equivalent to an Eee PC 900 or something.

About a year ago I downloaded the then latest version of ubuntu for netbooks, created a bootable USB drive from my Mac, as per the instructions at:url

or whatever the equivalent site was then. It booted fine, it installed fine and everything was great.

Eventually the tiny flash drive in my EeePC got full. I couldn't upgrade to the new 9.10 distro through auto updates because there wasn't enough room to download them.

I tried to delete some old kernels and then delete some other stuff. I broke my linux installation and now it won't boot to a desktop. I can get a login prompt and I can boot to the fail safe terminal but not much else.

So, I tried repeating the steps above.

I downloaded the NEW version of ubuntu netbook remix from:url

I followed the instructions for making a bootable USB stick from the first link above. I used the EXACT SAME USB stick as last time (in fact, it still had the older version of the ubuntu install files on it).

There were no errors "creating" the USB drive and it can be mounted on my Mac and I can see the files are on it.

I stuck it into my EeePC and rebooted and hit the ESC key and selected the Kingston USB drive to boot from. The light on the USB drive flashed some, then the internal flash drive light flashed some and the EeePC booted from the internal drive.

I rebooted and went into the bios settings and made triple sure that it was set to boot from USB drive first and rebooted. The same thing happened (it "looked at" the USB drive, then booted from the internal drive).

I repeated the above a dozen times. I REinstalled the ubuntu files on the USB drive from my Mac. I repeated. Still the same.

I redownloaded the ubuntu files and did everything from scratch. Again no errors "creating" the USB drive and it can be mounted on my Mac and I can see the files are on it, but again, it is absolutely useless because it is unbootable.

I tried booting my Mac from the USB drive and my Mac didn't recognize it as a bootable drive either.

I found another 4 gig USB drive and repeated the steps above with it. It was exactly the same: no errors creating it, the drive is mountable on my Mac, but it is completely unbootable.

I am at a loss to find any info on this nor do I have any idea what to try next. I KNOW this worked with the first USB drive last year (with an earlier version of ubuntu). What could possibly have changed?

Ubuntu Installation :: 9.10: Restore Unbootable System / Freeze?

Ubuntu Installation :: Crash During 10.04 Install Left System Unbootable

Jun 6, 2010

My son kicked out power during the install phase of 10.04 (about half complete) and now the system is unbootable.

The boot process dies shortly after starting fsck with the error:

init: plymouth main process (382) killed by SEGV signal

So this looks bad (to me), segmentation violations are never good.

So does anyone have any suggestions for booting and completing the upgrade?

If I'm SOL on this OS image is there a way to image over the OS and save my data?

The only option I see now is to buy a new disk, image onto it, mount my current disk and copy my data. (takes money and time)

Ubuntu Installation :: Failed Update Of 10.10 Results In Unbootable System?

Feb 4, 2011

yesterday I performed an automatic security update suggested by the update manager on my virtualized (with VirtualBox on a Windows 7 host) Ubuntu 10.10 installation.

The update somehow failed and left me with an unbootable system. When I try to boot, I am told that various folders, files, and what not are missing. Then the system drops into a busybox and leaves me with an (initramfs) prompt.

This happens with all kernels I get offered by GRUB, although the error messages are quite different from kernel to kernel.

Well, the short of it is this: I don't have the slightest idea on how to get back to a working system and this site is the final straw I'm willing to grab. A complete disaster like this following an update initiated and executed by the system is unheard of in Windows-land; at least I haven't heard of it, yet, and therefore I am going to abandon Ubuntu and Linux altogeteher, if there is no remedy.

Fedora Installation :: Acer Aspire 1410 Laptop Is Unbootable

Apr 8, 2010

I have an Acer Aspire 1410 laptop which was running Win7. The laptop lacks a DVD drive and came pre-installed with a recovery partition as well.I've been searching for ways to dual-boot Fedora on it. I bought a Samsung USB DVD drive, but I burned two copies of Fedora 12 and neither would boot, nor would my Knoppix Live CD. I even updated the bios. Then I tried liveusb-creator from my desktop Fedora 10 system, but I would still run into strange errors that prevented booting into the installer.

Finally I downloaded UNetbootin and created a USB stick to boot Fedora 12. Neither Fedora 12 nor Ubuntu would recognize my network adaptor for some reason. Undaunted, I then used UNetbootin to create a Fedora 11 image which got me into the boot installer for the first time. I then used my Fedora 12 image from my portable DVD drive to install. The install seemed to go well.

That is, until I rebooted. Grub came up as expected. Fedora 12 runs into a very early Kernel panic (not syncing: DMAR hardware is malfunctioning) within moments. I tried rebooting into Windows, but it apparently doesn't care much for Grub. It sends me into the Recovery software and asks me to reset my hard drive. I've tried that a couple of times now and it's useless. Is the problem with Grub? I thought it would play nicely with Win7 and at least allow me to boot into it, which is why I allowed it to overwrite my MBR. I lack a Win7 disc and cannot repair the MBR that way.

The new kernel has some features I think would be useful for me, especially the power management of ATI gaphics cores (I run crossfire 2870).

how I upgrade the kernel? I just wanted to check that I am doing the right thing. I had intended updating with apt-get using the age old instructions.

Ubuntu Installation :: No GUI After Kernel Upgrade?

Nov 28, 2010

I'm running 10.10 with an NVIDIA card which has a customised xconfig file (to allow use of an EDID file). This was working OK until I ran a set of security updates which included a kernel upgrade. Now when I try to boot the machine, it goes straight to terminal mode and will not run the GUI.

I recall seeing something about this before, but can't find the thread. It's a fairly simple fix to get the graphics running again, but I can't remember what the solution is.

Ubuntu Installation :: Kernel Upgrade Failure 2.6.31.20

Feb 13, 2010

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.

Ubuntu Installation :: Old Kernel In Grub After 9.10-10.04 LTS Upgrade

I performed an upgrade via the Update Manager from 9.10 to 10.04 LTS and it seemed to go flawlessly. However, now I cannot seem to be able to remove the old Kernel from 9.10 in the package manager. It does not even show 2.6.32-21 as installed but it still shows the old Kernel in Grub. I did a sudo update-grub but it was to no avail.

Ubuntu Installation :: Lucid Kernel Upgrade To Ppa. 2.6.37-12?

Jan 22, 2011

I wonder if others have upgraded their Lucid kernel using the deb [URL]..repository. I have been using the repository for some time now without any apparent problems, and have gone from 2.6.36-1, through 2.6.37-10, and am now on 2.6.37-12.

All of these seem to work with no problems at all, but I am just wondering if other users can also report success, or if there are any trip-ups that might occur. I still keep updating the "standard" kernel from the main repos, ie 2.6.32-27, so I have that as a backup, but I'm just very curious about other people's findings.

I just got the upgrade from 2.6.35.25 to 2.6.35.27.

Ubuntu Installation :: How To Upgrade Kernel To 2.6.35 On Lucid

Mar 5, 2011

I read recently about security flaws in the ubuntu kernel, and when I checked my kernel, it is 2.6.32-29-generic. I looked in synaptic, and I have the linux-generic meta-package - which should ensure upgrade to the latest kernel, and yet this is not being updated when I run update manager. There is a linux-image-2.6.35-25-generic, but the advice is not to install this directly (to avoid breaking dependencies, etc.), but to install the meta-package instead. Yet, the meta-package doesn't seem to be doing what is should do.

Ubuntu Installation :: Can't Upgrade To A Newer Kernel

Jul 22, 2011

It seems that i am stuck using the 2.6.38-9 kernel, since no matter what i try, i can't update. I have had this problem since 2.6.38-10, but figured that the problem probably would solve itself after the next kernel update, sadly that was not the case.

I have had some worrying error-massages from dpkg about broken packages, which i believe might be the source of this problem, as it reported that the package "linux-image-generic" was broken. I removed the postinstall script from /var/lib/dpkg/info and updated both dpkg and aptitude.

I am not getting any more error messages, and if i look in the synaptic package manager, i can see that kernel 2.6.38-11 is indeed installed, yet i can't select it at bootup, even though i have tried to manually update grub.

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.
