Ubuntu :: Error On Running Update-grub
Oct 10, 2010
I have an Acer Aspire One D250 with Ubuntu 10.10 Desktop installed on it, coexisting with a 12 GB Windows Vista restore partition The restore partition does not show up in GRUB like it used to, when I run sudo update-grub, I get:
Code:
Generating grub.cfg ...

On two Centos5 servers, yum gives a segmentation fault error when trying 'yum update' or 'yum check-update' after running 'yum clean' :
[Code]....
The error is the same for the other computer except while attempting to update the rpmforge repository. Nothing has really changed on the servers in some time and 'yum update' worked fine on each yesterday and I have no idea why they would both suddenly fail!

after initating the update and i enter my pass word, update stops and an error box comes up stating that it is unable to update because there is more than one synaptic manager running, i have restarted and get the same results, and to my knowledge there is nothing else running in the background.

Running first upgrade after installing 9.10.
Currently on item "Configuring linux-image-2.6.31-20-generic" and the progress bar/terminal readout has not changed for an hour or so I'd say.
Don't want to cause issues by killing it halfway through, especially as it presents an opportunity to learn something!

I have a VPS built with CentOS 5.4 64 bit, and I use it as a webserver (httpd & lighttpd)and mysql server. I used Jason's Utter Ramblings Yum Repository to install the latest PHP, apache, subversion, and mysql. However, I got problems afterwards when I try to run 'yum update' via SSH.

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.

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.

It started when I wanted to dual boot Windows 7 and Opensuse off of my netbook (No DVD/CD drive) I tried install suse from an external hard drive and I botched it. I ended up erasing EVERYTHING off of my internal netbook hard drive. Windows and all.
Well, I had a couple of other computers so I studied up and eventually successfully installed OpenSUSE 11.2 on my external hard drive (11.3 being the one that I accidentally erased everything with, so kinda scared of it) and now I want to install openSUSE 11.2 on my internal netbook hard drive.
I can not use disks
I can not use a flash drive (For some reason, even if I make it bootable, it will not load up, this could be because it's actually a 8GB microSD card that is placed in a USB card reader.)
I can not use an external hard drive because that's what I'm running suse off of.
I've tried reading up on how to install suse on another drive off of the hard drive and I've gotten as far as whenever I boot up the netbook with the suse external hard drive connected it will ask to boot into OpenSUSE, the Fail Safe, or to install OpenSuse. When I select to install it it gives me the Error 18 Unknown File system.
I've tried formatting the internal hard drive twice. One as NTFS and again as EXT4. Neither seems to effect it other than when it's ext4 I can open it and it contains a Lost and Found folder.
When I interrupt the boot sequence by pressing c and going to the terminal and I use the root (hd +TAB command it tells me I have a hd0 and a hd1. The hd1 only has 1 partition which is ext4, which I'm assuming hd1 is the internal hard drive (I'm not sure how to check) and the hd0 is the external hard drive, which has three partitions. One with an unknown file system and two with ext4. When I try to enter the set up from the terminal it gives me the same error for any thing I put it (e.g. root (hd0,0) gives the same error as root (hd0,1), or root (hd0,2) and root (hd1,0)
Something like it cannot locate these two files I'm assuming it needs to boot. If anyone finds this relevant I'll retry it and post the files its missing.
I've been searching for awhile and can't find any threads that can solve my problem. From other threads, however, I have noticed that I should probably include my menu.lst, listed below
Code:
I have also ran the boot info script and received the RESULTS.txt file it generates. Listed below

I'm trying to compile and install new kernel 2.6.32.14 in my ubuntu karmic. After compiling source and executing the deb package for the kernel, I tried to run update-initramfs but got "No space on device" error. My /boot partition size is 100 MB and is currently having 37MB free. After I run the update-initramfs command I noticed that space in /boot got depleted and soon came to naught which led to no space error thrown by gzip. I believe the resultant gzipped archive is no more than 20MB...then why is the whole 37MB is being used up? Please correct me If I'm wrong here otherwise I might be left with no choice but to increase the size of /boot partition. Is there anyway I can make update-initramfs to use the temporary space from other drives(may be /tmp) when creating gzipped archive?

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 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:
Code:

I have tried the testdisk/update-grub method, but it didn't work.

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?

Sometimes I connect to my Debian box from another computer (using SSH on Cygwin or Linux), and once ina while I want to run some console apps. And sometimes some of these apps might complain about "another intance, Error: an instance of newsbeuter is already running (PID: 2496)". Is there a work around for this issue at all(without killing the original instance") ? The reason I do not want to kill the app because there might be 2 users connected to the same machine that might be using the same app.
