Ubuntu Installation :: Can Repair An Ubuntu Install?
Mar 21, 2010
So here is the deal, I had been running Ubuntu 8.10 from the time it was released until about 2 days ago because when I went to 9.04, I got a warning saying that 9.04 didn't support any drivers for my video card. Well I decided to go ahead and upgrade to 9.10 so that I can upgrade to 10.4 LST once it comes out. Everything seemed to be fine but I turned it that night and left it running over night. When I got up the next morning, the screen was black and the computer was not responding. When I tried to restart it and it could not finish loading the OS. It made it about half way though and then the screen just went black. YAH!!! So far the only way I have been able to do anything with it was by having a Ubuntu boot disk in the CD/ROM when I start the computer. With the disk in the drive, whatever file or driver that the OS seems to be missing, it uses the one of the disk and loads just fines. So, no that you know how my day has been let me get to the point, does anyone know if the Ubuntu installer has a repair function and if not, can I just reinstall Ubuntu and let it reload the OS files without it deleting all of my files?

Im probally just being a noob here but for the projects sake I thought it would be good to identify this problem. I have an old advent laptop and I tried to install Opensuse from DVD on it. I followed the installation as normal but when I tried to boot it said some sort of check was forced and then I have to enter the admin/root password upon doing this I got the message system repair # in red. I have tried to repair the system through the installation DVD and tried re-installing it but I still get the same message.

I have a sony vaio vgn-AR71s with dual boot Vista and Ubuntu, no problems there.Since, over time, I messed up my previous Ubuntu setup while trying to get my wifi working, I decided to reinstall the whole thing and give it a fresh start. (as after two Kernel updates my wifi card drivers should be supported)I Reinstalled Vista and drivers after which I downloaded the latest Ubuntu 9.10 LiveCD, burned to a disc and rebooted.When the Ubuntu installation was almost finished I got an error, the disc I was using got overheated (bad quality CD) and there was a problem copying certain files. However my hard disk was successfully partitioned and divided in half (1st partition Vista -NTFS and second Ubuntu -Ext4). But my laptop still boots directly into Vista ignoring the partly failed Ubuntu install, no boot option at startup.When I reboot using the LiveCD I can only install Ubuntu on a newly created third partition.
Is there any way I can continue or repair the previous ubuntu install? I searched this forum and the internet for options and hints yet don't seem to find an answer.The good thing is my wifi card is finally working (when I booted from the LiveCD it immediately detected wireless networks yeay)

I got my laptop repaired (by the manufacturer). Linux would install fine before, but not now, as all I get is a black screen with a blinking cursor. Note, I've only tried KDE versions of software since my laptop came back, so I don't know if that's the problem. I tried linux mint 9 and kubuntu 10.04. And all I get after a while is described above. I also tried some different install options, because I'm able to get to the menu to choose which type of install I want, but the other options led to the same thing, and it would sometimes display a bunch of numbers and then "EH ok" or something. the numbers on the left keep increasing, and eventually I get to the splash screen, where it freezes, and repeats the process.

Can you repair an existing install with a distro CD, IE Run the install with a switch to just repair rather than "install".I have messed up a Ubuntu 10.4 Netbook install by playing with the Mount Utility trying to mount a SD card, and now my netbook will not boot.

I had been running ubuntu 9.03 for quite some time, but for school I needed windows, so after installing windows on a free'd partition, it will not give me the ubuntu boot option and loads staright into windows(vista)[typical windows]. I am aware that one is able to repair it with an ubuntu boot disk, but my dvd-rom isn't functioning.My question is, is it possible to repair it with a USB stick instead?

I recently upgraded to 11.04 on my WUBI and after a while the OS just stopped booting. Every time I try to boot it drops to the grub command line. I can't boot manually because it says file not found when I enter "linux /boot/vmlinuz-2.6.38-8-generic" And I can't repair the installation through the LiveCD as it gives the error message:"(initramfs) mount: mounting /dev/loop0 on //filesystem.squashfs failed: Input/output error.Can not mount /dev/loop0 (/cdrom/casper/filesystem.squashfs) on //filesystem.squashfs".Can anyone help with restoring the OS?

I was trying to upgrade to 11.2 from 11.1 by upgrading the OS online. However my internet connection failed and the upgrade has now messed up my system. I have a dual-boot system with Windows XP and I'm wondering if it would be OK in getting the DVD and selecting update? Or do I have to change the boot log etc?

So I have been messing around with the new 10.04 and I managed to screw it up. When I started to log off, I closed the lid to my laptop so it would hibernate, but instead the screen went black and I could only see the cursor. It stayed like that for several minutes so I shut it down manually. When I booted it up again, it froze on the splash/loading screen and I haven't been able to boot it since. I've tried to boot in recovery mode, but I think my campus internet interferes with the downloading of the necessary files from the internet. Is there any way to boot a recovery mode from the install disc? Or am I SOL?

I am currently in a country where the internet speed is roughly 15KB at best, if at all. So I cant download the 9.10 live CD. My grub2 broke when I reinstalled windows (because its so virus prone). This guide: [URL]. Says how to repair grub2 using grub2 live CD. Currently I have access to a 6.10 Ubuntu CD but when I try to mount the boot partition I get an error saying that the filesystem has unknown options. I think that the latest filesystem didn't exist back then and even if that would work. Can I reinstall grub2 using grub? Or is there any possibility to download an ultra small linux live system image with grub2? it seems all ubuntu variations come in 500MB+ packs.

I get this message when I boot
init: udevtrigger main process (440) terminated with status 1
init: udevtrigger post-stop process (449) terminated with status 1
init: udevtrigger main process (447) killed by TERM signal
I'm now on the live cd, is there anyway to either fix that, or just repair the system? I tried booting in safe mode too, none of those started up either.

I have Ubuntu 11.04 on an AMD64 machine (HP Pavilion DM1). It worked fine for a while but recently any time I try to invoke the Update Manager.I have had some incidents of being unable to resume after sleep (until I disabled the catalyst driver) so possibly in one of those that file got hosed.

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 think a recent update to 10.04 somehow has broken my installation. When I turn on the machine, it just sits at the splash screen with the white dots turning orange from left to right as if it is going to boot up.
I have tried letting it sit there but after half an hour it still remains the same. I have tried booting into recovery mode but that fails somewhere along the startup process. Is there a way to 'repair broken installation' when booting up with live cd? I have been able to get to that option and I am trying to avoid doing a fresh install if possible.

When I attempt to boot into Ubuntu 9.10, I get the error: "Error 15: File not found" I know the reason for this - I deleted it - Doh. A latest upgrade told me I didn't have enough room in the boot partition to install the latest files, so I thought it would be a marvellous idea to remove the old stuff, to give it some room. I obviously deleted something that I needed by mistake. I was using synaptic to do the remove & thought I would be safe. A good learning experience.
In grub menu I have options: Kernel: 2.6.31-15 - generic and also its recovery option, both of which get the same error. (It's a dual boot with XP as the original os). Ideally I'd just like to get the latest working kernel and put it somewhere appropriate, rather than do a full install. Is this possible and if so how? I have a separate boot partition (in dev/sda5), swap (sda7) and Linux (sda6).

I am running a 64bit 10.10 with gnome. Its pretty much a fresh install. I saw a project called CAINE, it looked neat so I'd thought I'd give it a try, something in the installation mucked up. Now when I open the Software center I get a message telling me "Items can no be installed or removed until the package catalog is repaired" I click repair and I get this error message: E:I wasn't able to locate file for the caine-from-deb package. This might mean you need to manually fix this package.:So I thought I'd give it a go using synaptic package manager, it gives me these error messages: E: caine: subprocess installed post-removal script returned error exit status 2 E: caine-from-deb: subprocess installed post-removal script returned error exit status 2.I am currently unable to install or update any software at the moment so I really need help to get this fixed.

I have installed windows 7 back to its former state in after foolishly messing around with some installation options in an Ubuntu install (this caused windows to disappear, and me to repair it). In *repairing* windows, I overwrote my grub file and the boot options for Ubuntu, so that it looks something like this:
Disk 1: Primary Partition - Windows 7
Disk 1: Secondary Partition - Windows 7
Disk 1: Secondary Partition - Free Space ( this is where I have Ubuntu installed)
How can I repair my grub file so that I can boot into my Ubuntu installation?

My system got stuffed after a trivial online update, it downloaded a new kernel update, I rebooted and now it won't boot at all saying "FATAL: Could not load /lib/modules/2.6.31.8-0.1-desktop/modules.dep: No such file or directory", then some stuff, then "mount: unknown filesystem type 'ext4'", "could not mount root filesystem"... It's on my laptop without a DVD drive and I've only got a LiveCD USB stick which doesn't have a YAST system repair tool. Is there any way to repair a system without a DVD drive?

I can't find the repair facility when running the openSUSE 11.3 install DVD. In earlier editions it was on the Installation Mode screen, three options:
New Installation
Update
Other Options
Under Other Options there used to be a repair function. I can't find the repair facility in 11.3. Is it now located somewhere else, or has it been removed?

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
[Code]....
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 initially had a dual boot where I could decide to either boot into Windows 7 or Ubuntu 10.04. It work seamlessly. At some point, however, when I booted into Windows, it just seem to only load it "half" in the sense that the desktop just turned black (but when ctrl-alt-del was hit I did receive a screen with the different options).
I suspected there was a problem with grub and proceeded to restore the Windows bootloader by booting into the Windows CD and repairing the computer by entering the commands:
After restarting I suddenly do not have the option to boot into Ubuntu (where did it go?) and booting automatically into Windows the original problem persists.
Any idea what happened here and how I can restore things?

both root and home partition have suddenly become corrupt, and the repair tool from the installation disk just loops (Do you want to repair? Yes! Do you want to repair? Yes! Do you...).
Code:

but I know a fair amount about the OS. I really like openSuSE, and I was trying to install 11.2 on my laptop, completely blank hdd. It installed just fine;I used the default options (the partition scheme was /boot, swap, root, /home) and started thesktop without a hitch. However, when I restarted, my BIOS would not even recognize an OS on the hard drive. I was also unable to boot using the installation DVD. I tried to use the repair feature, and I would either get a message saying that the boot loader was corrupt,d could not be repaired, or that the package database didn't match the version of openSUSE installed. I've tried re-installing multiple times, all with the same results. I have tried different partition schemes and I've tried different booting settings, such as enabling boot from root or /boot partition
