Ubuntu Installation :: Repair/restore Grubin A Multiboot System
Apr 3, 2010
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.

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?

've been looking for the answer both on the web and this forum but I couldn't find it;How can I put Ubuntu, Encrypted Ubuntu (Luks + LVM), Backtrack and eventually WinXP on the same drive with a Grub2 as a bootloader?I'm a bit confused about partitioning; I suppose that I need only one /boot partition to store the kernel of the encrypted Ubuntu, while the other distros will have their /boot within each partition, like this:
1) 500 Mb; /boot for the encrypted Ubuntu on partition #2
2) 10Gb; Luks + LVM Ubuntu
3) 10Gb; clear Ubuntu (whose /boot is in same partition #3)
4) 2Gb; Backtrack
5) [Win..]
In this case, will the update-grub command find and recognize correctlyll the OSs or should I edit something in the "40_custom" file

I have a triple boot system with Windows XP, Debian Lenny, and Fedora in that order as far as the disk partitions, and Lenny's grub controlling the multiboot. This has worked well for yearsRecently the Debian got corrupted with someependency issues, and I want to install Squeeze inplace of the existing LennyI don't need to save anything from the Lenny). Is this possible, usinga startup install CD for on-line installation of Squeeze over the Lenny partitions, and also without disturbing the Windows and Fedora boots? If it is, are there any manual steps to be taken during
the installation?

I installed Gnome 3 on a free partition of my netbook but I lost the boot to my suse kde...(MBR). I launched a live CD on USB but cannot restore Grub; the only way is to reinstall the KDE. Then it boots but does not show Gnome 3. Why the installer does not take into account both OS?

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.

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.

16GB RAI've been running the Debian-based Proxmox VE on it for six months or so with no problems.Today I loaded Centos 5.5 x64. During a reboot, the file system crashed and fsck couldn't repair.I loaded it again, did all the updates, and loaded my applications. On about the third reboot, it crashed again and fsck couldn't fix it.I don't really know where to begin. I doubt seriously that any hardware has went bad since yesterday.

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 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.

I downloaded and installed fedora 10 on the second partition of the second harddrive in my system. I installed grub on the second drive as well. I added windows XP (the entire first hard drive) and windows server 2003 (the first partition of the second HD) to the boot list. In my bios I set the second HD in the boot device list.Now I can boot fedora 10 BUT when I select xp or server 2003 I get an error message that reads:- NTLDR is missing.

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 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 Windows XP and OpenSuSE 11.1 installed on my laptop. I have recently removed the recovery partition provided by the laptop manufacturer (HP) to free up some space and ideally I would like to be able to add the free space to the existing Windows partition.The current partition set up is as follows:
Code:
Disk size 93Gb, P = Primary, L = Logical, U = Unallocated
P Windows XP 36Gb /dev/sda1 /windows

My Mini13 came with hardy preloaded, and it's got pretty messed up since, so I'd like to restore factory OS via a grub entry that looks like this:
title System Restore
root (hd0,2)
chainloader +1
boot
This points to a partition which, when mounted, has this stuff in it:
bootfs.img initrd0.img install.sh logo.png syslinux.cfg vmlinuz
boot.msg install.cfg ldlinux.sys rootfs.img vesamenu.c32
I'm not a computer, but that looks pretty good to me but when I select this grub option it just says:
Boot Error
Is there a log or something that might give me more info about the error?

I have an installation from USB/DVD issue.
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 2.6.22.5-31-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.

On startup I heard a 'click' around the time "loading hardware modules" and "loading kernel drivers" was showing on the monitor. Then all the system sounds became fuzzy (corrupted?). Other sounds, such as VLC playing a music station, are fine.

I'm using Ubuntu Lucid and any sudden power loss will usually cause problems with the file system. When I bring the computer back up, Ubuntu will then scan for errors at boot-time and if any errors are found it prompts me to select whether to repair or ignore them. I would much rather have it select the repair option automatically so that I don't have to be physically present.The reason for this is that i have a web server that should come back online automatically after a power loss.

I booted up Ubuntu after a couple weeks of downtime. I think it had just installed updates before I shut it down. It seemed fine. I started updating it, then it started giving me a bunch of errors about the root file system being mounted read only, so I had to reboot. I've heard that it does that if the file system is corrupted or there is a hard disk failure. When I rebooted, it kernel panicked on all but the oldest kernel which did a fsck and rebooted. Then I was able to get back in, but most of my panel applets are gone and cannot be restored, it fails to start x at boot with no errors and I have to start it myself from the command line, it is unable to do updates, samba is gone, whenever I update-grub to add Gentoo to the list, it doesn't stay there and the computer is really slow. I have backed up my home folder to another partition. Do you think I will be able to repair it at all or should I just reinstall?

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 fouled up the file system when removing a drive. How do I fix it, or do I need to re-install?
The system boots to the point in the GUI where it checks the file system. It then suggests that I run fsck without the - a and -p options, and the drops to a sheel.
I enter the root pwd and then it says: "(Repair fileystem ) 1#" What do I do from there?

I want to multiboot several Distros for experimental purposes. My main distro is Ubuntu 10.04.Hard drive is partitioned like such: /dev/sda1, grup bios, size = 977 Kib/dev/sda2, file system ext4, size 1.8 Tib, this is mounted on / /dev/sda3 linux swap, 4.3Gib.My question is can I use Gparted to partition a second space out of sda2, and install another Distro? Do I mount it on / ? and will grub boot see both OS without destroying the kernel of my old distro? I am assuming to partition my hard drive I have to unmount it, but can I do this without using a live cd? So many questions and so little help, because apparently this is an easy thing to do.I am just worried just seems that what I just described is too easy and I will probably destroy everything and have to start over.
