Ubuntu Installation :: 9.10: Restore Unbootable System / Freeze?
Jul 11, 2010
I updated 9.10 and system crashed during update and is now unbootable. It seems to freeze (or is just taking a really long time) at fsck. Is there any way to make my computer usable again without reinstalling the whole OS?
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.
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.
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.
I am trying to restore my system to Ubuntu 10.10, using a system backup made with REMASTERSYS. When I reboot, I get the message: GRUB error:15 I found many threads discussing this issue, most notably here: [URL]
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 ).
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 (188.8.131.52-smp). Second, how can I get myself out of this rut without reinstalling?
Code: lba32 append=" vt.default_utf8=0" boot=/dev/sda vga = normal # Linux - Slackware image = /boot/vmlinuz-huge-smp-184.108.40.206-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
I have installed Ubuntu Lucid Lynx Alpha on my computer.was running fine until I installed usplash. Now when I boot up I get a message saying "Ubuntu is running in low-graphics mode" and a list of options. When I select any of them and press Enter I get a blank screen. I can't even load a command line. I want to remove usplash to see if that fixes the problem, but I would have to do it from another OS. How could I do that? My other operating systems are Ubuntu Karmic and OpenSUSE.
[I'm not sure if this is the right forum. This is the closest I've found]. I've installed Ubuntu 10.04 LTS (dual boot with Windows XP SP3). After Ubuntu starts, it takes about 10 seconds, and the computer halts. No screen/mouse/keyboard activity. If I start Ubuntu under Recovery Mode, with failsafeX, it doesn't happen.
In the Windows all is fine. What did I wrong? [My CPU is: Intel(R) Pentium(R) Dual CPU E2140 @ 1.60GHz, if it matters...]
So when i initially boot (both using wubi and a usb stick.) it will start to go and then do the alternative boot option with a 5 second count down. Then if I'm lucky it will get passed that then either a black screen with just a flashing _ on it and it will freeze there. Or it will go to the ubuntu opening with the little dots for initial boot and it freezes there. (the dots don't move more then two and then it really freezes.) My specs are i5 750 Nvidia Geforce GTS 250 1.5 TB harddrive ASUS P7P55-M LGA 1156 Intel P55 Micro ATX Intel Motherboard Windows XP home edition 2006 with SP3.
are there any sweeper / cleaner apps which can take back my installation as to when it was new. I know home directory could have config files etc..but that doesnt matter, i want all packages and applications reset to how it was when i had a clean install. I am using Natty
OK, so about a week ago or so my Ubuntu 10.04 install no longer recognizes my iPod Touch or Iphone. I have had no luck getting them to work. i REALLY do not want to fresh install Ubuntu. Is there a way I can like repair or restore (a la "Window$") that will fix the OS itself without removing any programs or settings?
I would like to find out how to back up a complete Ubuntu system, and then restore it on a clean harddisk.I have been running dual booting with Win XP until now. I am running Ubuntu 10.04, but have installed quite few add-on. I would like to make an Ubuntu-only machine now, with all the same apps still there, but dont want to go and download everything again. I am looking for a way I can back this entire Ubuntu installation up, and then restore it to a clean drive.
I recently had to restore my system via clonezilla due to hdd failure. I frequently back up my /etc/apt folder as well as some other configuration files and settings that I use in my system to bring my restored image up to date with my ever changing preferences, etc.
I noticed the problem when I replaced the etc/apt folder with my backup version. After replacing the folder, I ran 'sudo apt-get update' and imported a list of all my previously installed software. Then I ran 'sudo apt-get upgrade'. I didn't get any errors at all during any part of the update and upgrade process.Then this popped up in my panel, and won't seem to go away.
On my laptop I dual boot Ubuntu 8.04 and Windows XP. During the last upgrade of my Ubuntu distro something went wrong and now I get a messed up GUI. In the meanwhile I got a new laptop on which I only run Ubuntu 9.10. So my question is: I want to delete the linux partition on my old laptop and use only Windows XP but since I use grub to dual boot, I'm afraid that deleting the linux partition and extending the Windows partition will cause problems to boot my computer. Here's a screenshot of my partitions:
I have a laptop with 250 GB SATA HD that has the following:
Win7 Pro installed first with sda1=system reserved partition, sda2=C: drive, sda5=separate software application programs to differentiate from Windows' Program Files. Ubuntu 9.10 was installed next (sda6=common swap partition for all Linux distros, sda7=Ubuntu root, sda8=Ubuntu home). Then Opensuse 11.2 was installed with sda12=root and sda13=home. Finally FedoraCore11 was installed with sda9=boot, sda10=root and sda11=home. Ubuntu and Suse have grub loader in their own root partitions.
Suse's grub menu controls all OS's. From this grub menu I can select Windows or any other Linuxes. Suse uses legacy grub because it was installed right after Ubuntu 9.10 which uses (legacy) grub.
Here is opensuse's grub menu:
# Modified by YaST2. Last modification on Wed Mar 31 11:49:28 EST 2010 # THIS FILE WILL BE PARTIALLY OVERWRITTEN by perl-Bootloader # Configure custom boot parameters for updated kernels in /etc/sysconfig/bootloader default 1
Somehow I also messed up Windows' boot file and boot partition table. Now I am still trying to use Windows installation CD to repair Windows but it has taken several hours and am still waiting for screen response. I cannot boot into any Linux distro either.
I have just foolishly used live media to install F14. Pre-upgrade of F13 to 14 repeatedly failed. Sadly I used the use all available space option rather than the free space. As a result I have a working FC14 system but no data from my F13 installation. Is there any way to restore my f13 system and/or data?
probably did something stupid.. just haven't figured out what yet.. hope someone can point me in the right direction. daughters computer broke, maybe virus, so i did clean reinstall of xp. decided to give her a couple of linux distros, thinking maybe they are safer for when she is surfing..
Used gparted to repartition hd:
Partition table entries are not in disk order
Installed Ubuntu 8.04. was then able to boot into either ubuntu or xp. next installed fedora 10. new menu.lst did not show ubuntu, only fedora and xp. had some lockups in fedora, and had to pull plug to reboot 2 or 3 times. replaced power supply. added ubuntu into menu.lst. boots into fedora and ubuntu fine. tried to boot xp, and get "Preparing System Recovery Option", then PC Angel appears, and it wants me to use the system restore option for xp.
Is there something i can do to recover xp without having to wipe the hd and reinstall xp, then reinstall ubuntu and fedora (and if i do all that, how can i be sure i don't end up with the same problem?
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?
Setup: 1. Desktop running WinXP 2. Lenovo S10e netbook running Win7RC1 (just expired.) no DVD drive. 3. 1 DVD by Novell and Lenovo with "SUSE Linux Enterprise Desktop 10 (For recovery select Restore System from the initial Menu.) November 2008" 4. 4GB USB drive. Laptop can boot from it.
Problem: Need to install the system to the Laptop using the USB drive. Doesn't install. What I did: Mostly followed the guide at "Installation without CD - openSUSE.htm" my USB drive is G:
used the HP USB Disk storage format tool to make my USB bootable. Copied all files from the dvd to the usb drive Moved G: ooti386loader* to G: Deleted E: isolinux.bin Renamed E: isolinux.cfg to E: syslinux.cfg Downloaded syslinux-3.85.zip from [kernel.org] Extract syslinux-3.85.zip to c: syslinux CD'ed to c: syslinuxwin32 directory in a cmd prompt Ran syslinux -ma E: .....
Result: Runs all the way through, gets to a windowed program called ">>> Linuxrc v3.0.20 (Kernel 220.127.116.11-31-default) <<<" Code: could not find the openSUSE Repository. Activating manual setup program
Main Menu: Settings, System Information, Kernel Modules (Hardware Drivers), Start installation or System, Verify Installation CD-ROM/DVD, Eject CD, Exit or Reboot, Power off Cant find anything on the usb drive (obviously?) so what do I do now?
This is where I'm at and quite stuck... not sure what other flags there are to use, what I have to move around or rename.
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.
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)?
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?
I was running Windows 10 on MSI GT70 2OD-064US hoped to dual boot first had three primary partitions shrunk largest one and ran debian-8.3.0-amd64-netinst.iso chose guided install with remaining free space, didn't force UEFI asked if I wanted to install GRUB after finding Windows Vista (loader) I went ahead and installed. Couldn't boot afterwards with dark screen saying no install media, changed BIOS to legacy mode and got grub prompt followed tutorial and entered these commands:
grub> set root=(hd0,5) grub> linux /vmlinuz root=/dev/sda5 grub> initrd /initrd.img grub> boot
This caused it to boot without GUI I ran grub-update and restarted back at grub> again. How to get debian to boot or even windows 10 again?
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.
