Ubuntu Servers :: Grub Error 18 After Apt-get Update?
Nov 13, 2010
I had to restart my server after it became unstable - strange things like couldn't connect from a Windows machine, becoming unresponsive. When it rebooted, it failed with grub error 18 (this after the machine has been fine for some considerable time, including rebooting).I ran apt-get upgrade shortly before my problems started, and google suggests that I'm not the only one to get this error after apt-get upgrade, but I can't find a solution.I really, really don't want to have to rebuild this machine! I can get in using the recover a broken system option on the install CD - the disk seems fine.

I'm currently setting up a dell server with hardware raid 1 on sas 6r. i got 4 sas installed on the server and configured to raid 1 as stated below,
array 1:
slot 0 & 1
array 2:
slot 2 & 3
during the installation, the installer detect the array 2 as sda and array 1 as sdb.. so i proceed with installation on array 2. after completed the installation, the first reboot lead me to a 'grub-rescue" prompt. by following the guide at url Mode, i've noticed that the boot folder has changed to (hd1,1), which i believe it has changed to sdb1. default root device shows that prefix=(hd0,1)/grub.

After lots of searching last night I noticed that over the last couple of days there have been quite a few posts of people receiving the error: no such device lots of numbers grub rescue>. I have a dual boot vista/ubuntu setup with ubuntu on my d: drive and windows on my c: drive and it happened to me last night. So after my freaking out when I received the grub rescue> error after updating somethings in my ubuntu install and restarting. Once the computer rebooted bam! error. after much freaking it only fixed itself by reinstalling the windows bootloader via the vista rescue disk I was wondering if there was a way to prevent this from happening again? will ubuntu attempt to "update" itself again?

With a bit of help from this forum I managed to install 10.04. The solution was to add i915.modeset=1 to the options when booting up from CD.Now I need to do the same in order to boot up from HD. I've opened /etc/default/grub and changed the relevant line to include the above option. But I need to run "update-grub" and it comes back with an error to the effect that it 'can't find a device for / (is /dev mounted?)Also, the boot menu only has ubuntu - no sign of windows in my intended dual-boot. What can I do?

I have a new acer machine which runs fine on 10.10 mythbuntu desktop livecd. Install seemed fine.
Then I ran an update and on reboot I get a kernel panic error. Research on this reveals it as a very deep subject which can consume many hours, so I opted to reinstall.
This time with ubuntu 10.10. I've tried different CDs, liveusb. Same errors.
So, the question is this - where do I concentrate my efforts - somewhere ubuntu doesn't like this machine, or grub. Does a reinstall overwrite the grub install too? Or do I have a bogus grub install I need to purge before I will get anywhere.

I have an old computer that I use for trying out software and other things before putting them on my newer machine so as to avoid irreparable damage. The machine has 2 hard discs; the first disc contains Windows and I wanted to use the second disc for Linux. I installed Fedora 14 on the second disc and followed this with Ubuntu 10.10.
After I installed Fedora I re-booted and had a choice between booting into Windows or Fedora. After adding Ubuntu I assumed that Grub2 would pick up both Windows and Fedora and add them to the grub menu but instead, the grub menu only contained the options to boot Fedora or Ubuntu. I tried running 'sudo update-grub' but got the following message:
"cannot access /var/lib/os-prober/mount/boot
Boot: No such file or directory"
When I had a look in /os-prober all that was there was a file called 'labels' and when I opened it it consisted of the one line "Fedora 1" It looks to me, who doesn't know a lot about grub2, that something is missing from grub and had wondered whether to re-install it or whether doing so would be jumping out of the frying pan into the fire.

I have a dual boot system with ubuntu 9.10 x64 and Windows 7. Everything has been working fine for a a long time but yesterday I tried to delete an unused partition through the Disk Utility in ubuntu (System->Adminstration->Disk Utility) and everything was messed up. I used to get the "Grub error: Unknown filesystem". I managed to create an ubuntu bootable usb and followed some tutorials for fixing grub but all i managed to do is to get another error: "Grub error: No such disc". After some experimentation i got
"Grub stage 1.5" which gave me a grub> command prompt./dev/sda is the drive containing Windows and Ubuntu.

I am new to Linux. I have installed RHEL 5.4 on my PC with preloaded Windows XP.
Windows was set as the first boot kernel. So if i do not choose which OS to be loaded it will load Windows by Default.
Today I got an error saying GRub Loading Stage2 read error.

I am trying to set-up a home server using Ubuntu 9.10 server edition. My PC has 4 x 500Gb SATA drives which I will use for storage. I also have a 80Gb IDE drive which I want to install OS on. During installation the 80Gb IDE drive shows as sde. When doing the install I chose to install to whole disk (sde), all appears to go well. When I reboot all I get is "GRUB loading, please wait.... Error 15" Is the problem caused by my drive being sde and not sda? I have also tried partitioning sde as /. /boot and swap, still get Error 15.

I have an ML570 G4 with a P400 array card. Ubuntu server 10.04. I added more drives and extended the size of the partition to 2048gb. Now on boot I get Grub Error 18. The live cd sees the partition I just cannot boot it. I've googled around quit a bit,but have not found much that is relevant. I believe I am going to be adding a smaller boot partition to the beginning of the drive to fix this

I was unaware of the difficulties of installing and booting Ubuntu from the "onboard raid" that the NVIDIA nForce chipsets provide. However, I've managed to get it working reliably with one single caveat:
When update-grub builds the grub.cfg, it refers to all of my partitions as follows:
Code:
menuentry 'Ubuntu, with Linux 2.6.35-27-generic' --class ubuntu --class gnu-linux --class gnu --class os {
recordfail
insmod part_msdos
insmod ext2
set root='(/dev/mapper/nvidia_caifaefg,msdos5)'
[Code]...
So I'm guessing that the whole nvidia_blah,msdos5 is because of that. However, it doesn't seem to explain why Grub would THINK that would work and it in fact does not work. That's the biggest source of confusion on my part.
My questions are as follows: First off, because as an IT person I want to know: Why does this sort of change work? What does changing that device name change in GRUB's behavior? Is there a setting in /etc/default/grub that would change the way it's naming these RAID devices? Is there a value for this setting that would give me the device names that work, as explained above?
If there is no setting change I can make in /etc/default/grub, could I add a sed command on to the end of update-grub or can I make a modification to one of the scripts in /etc/grub.d? What sort of change would be recommended? How would I preserve this change through later package upgrades that would possibly rewrite these files?

I have an old BIOS (only 149 GB detected in 160 GB drive). I have installed very few OS as a result - Windows in first 80 GB , 2 distros (20 GB each) in next 40 MB which is within the 149 GB. On issue of "update-grub" grub seems to detect all OS and generates grub.cfg. But on boot , one distro does not appear in the menu.

I have 2 hard disks. sda,sdb
In sda, I have 4 partitions, and I have windows 7 in one of the extended partitions [not in the primary partition].
In sdb, I have 3 partitions. 2 for storage, and 1 10GB drive for Ubuntu. Again, Ubuntu is not of a primary partition.
I had ubuntu 10.04 running on that for a long time. However, I wanted to reinstall ubuntu and use 10.10.This is what I did EXACTLY:Booted from Ubuntu install CD
Chose advanced istall
Selected sdb3 for Ubuntu
I installed GRUB2 on the SAME partition as Ubuntu aka sdb3 Installed then rebooted
I can boot into Ubuntu fine, but whenever I select Windows 7 bootloader from the GRUB menu, the screen goes black, and my PC reboots.
Boot Info:

Ran the updater, went to boot to Win7 to use Photoshop and realized that the grub menu was gone. Ubuntu boots by default now. I tried running "sudo update-grub" at a virtual terminal and while it listed the various linux kernels ok, it then got caught in a loop spitting out some crazy looking errors. I rebooted and Ubuntu came up fine. I tried running "sudo update-grub" again from the gnome terminal and it hangs the whole computer for a few minutes and finally gives me this:

When I try and boot my Debian computer I get the messages: Grub Loading stage1.5. Grub loading, please wait... Error 15 Is there any way of recovering from this - or is it simply a fresh install? I was attempting an upgrade from Lenny to Squeeze and despite a few hurdles it looked like it was all happening. Got the new kernel loading, and the new grub. It looked as though grub2 was working so I ran the grub-remove-legacy-support command (something like that) and now my computer won't boot grub or Linux.
I'm assuming the MBR on my harddrive is lost, however I don't know what state the partition is in. I'm guessing that maybe this has been lost as well. I tried a few tools from the Ultimate Boot CD but nothing here was able to re-install my grub or boot from any partition or even mount my file-system. I'm fearing the worst but would like it confirmed before I blow it all away with a new install.

After certain system-wide changes, like kernels updates, I obtain grub prompt on restart. However, if I put the hard drive into another computer (b), it boots up fine. Since, however, I use the present computer (a) regularly, I only use b to purge and reinstall grub using the chroot method. However, doing so every time is time consuming; and I cannot change anything in the defaults and run update-grub without obtaining a grub prompt on restart. How do I fix this?

I have Ubuntu Karmic 64-bit installed. Update manager tells me there are updates available, but when i try to install them, downloading the updates fail and throws this error:
Code:
Failed to fetch http://security.ubuntu.com/ubuntu/pool/main/e/eglibc/libc6-i386_2.10.1-0ubuntu16_amd64.deb
Consequently, a similar error occurs when I try installing Sun Java 6 Runtime.
Code:
Failed to fetch http://archive.ubuntu.com/ubuntu/pool/multiverse/s/sun-java6/sun-java6-jre_6-15-1_all.deb Connection failed [IP: 91.189.88.31 80]
Ubuntu Restricted Extras stalls when it's time to download the Java package I tried synaptic, update manager, aptitude, apt-get, and they all throw similar errors. Then I also tried connecting to different servers, to no avail. So to check if it's my connection to the net that has problems somehow, I tried downloading the file directly through my web browser, and it works. (But it's not recommended, and it won't let me!, install the updates manually, right?) I tried searching for the errors on the net and in the forums, and they're all somehow related to proxy servers. I then checked if I'm using some inappropriate proxy settings, and everywhere it's all set up to connect to the net directly, which is, well, my setup.
Take note though, that I am able to install other softwares normally, i.e, using synaptic, apt-get etc. The ones I tried include Pidgin and Mplayer. It's just these updates and Java:
Code:
jeanne@jeanne-desktop:~$ sudo sudo aptitude upgrade
W: The "upgrade" command is deprecated; use "safe-upgrade" instead.
Reading package lists... Done

I was running 10.04 LTS and had decided to stick to the LTS versions as I'm now running my machine as a server and don't want to be updating regularly.Every time I logged in via SSH I got a message telling me there where packages to update including a security update. So I did a search to find out how to perform an update on Ubuntu server from the command line.What I found was to do this:sudo apt-get updatesudo apt-get dist-upgradeAfter doing that I rebooted but now my machine gives me this message:
init: ureadahead-other main process (794) terminated with status 4Your disk drives are being checked for errors, this may take some timePress C to cancel all checks currently inprogressI'm not pressing C yet and leaving it alone to finish, but I noticed when the machine booted that one of the options for booting talked about Ubuntu 10.10, so I'm worried that I've updated from 10.04 LTS to 10.10 by accident?

I've trawled the internet but can't seem to find the exact same issue, so I've made a new thread. So, I installed Ubuntu onto a 160gb drive. I have other drives in the system, but I disconnected them so that the system drive would be sda. Ubuntu installed perfectly with no issues whatsoever. I connected the other drives in the system, and again it booted up perfectly (although I can't remember whether the 160gb drive remained as sda or became sdd). Then I attached some extra drives temporarily to do some data shuffling.
This moved my system drive to become sdf. My computer booted fine multiple times like this, but when I was finished with the drives I rebooted and suddenly everything broke. For some reason my ubuntu installation showed up in the GRUB twice, and neither of them booted. So, I popped in the Live CD (which I'm using to type this post), and decided to update the grub. I chrooted into my system drive and ran update-grub, but it simply returned something like this:

I'm trying to edit my Grub menu by removing the older kernel after I ran updates as well as make my Windows 7 install first on the list.
I ran...
Code:
sudo gedit /boot/grub/menu.lst
and edited it accordingly.
After that I ran...
Code:
sudo update-grub
I restarted and see no changes on my grub menu. Running 1.97 beta4 if it makes a difference.
Oh and btw I am a complete n00b with linux.
