Ubuntu :: Multiple GRUB2 Listings For The Same Kernel Version
Jun 5, 2010
I did a fresh 64-bit install of 10.04 workstation a few weeks ago, and my grub seems to "double up" the listings of my kernel versions. I have removed the older versions hanging around on my system, but you can see in the list below, that I still get the listings more than once:
jim@jim-laptop:/etc/grub.d$ sudo update-grub
Generating grub.cfg ...
Found linux image: /boot/vmlinuz-2.6.32-22-generic
Found initrd image: /boot/initrd.img-2.6.32-22-generic
Found linux image: /boot/vmlinuz-2.6.32-22-generic

Sometimes a kernel image seems to have the same version as the backported kernel image, for example:
linux-image-2.6.32-bpo.5-amd64
linux-image-2.6.32-5-amd64
What are the differences between the two?

At the moment I am using kernel 2.6.31-14-generic. I'm not one of those people who needs to have the latest and greatest kernel to be happy, I just rely on the update manager. I swore that I saw an update for a new kernel, but my kernel version hasn't changed. I'm just curious if there was a new kernel that was released or if that was just an update to the kernel listed above.

/dev/sda1 - 105GB - Windows
/dev/sda2 - 200GB - Extended
/dev/sda5 - 110GB - Media

I am having trouble with setting up the grub based system on my external hdd. I am trying to have one grub which is going to load operating systems, and livecd if any (usb install). I am stuck at installing Ubuntu 10.10 Minimal version (i don't need gui for linux).Here is what I have done so far:
1. Created 2 primary partitions - windows 7 recovery and data (ntfs)
2. Created an extended partition for linux stuff.
3. Create a logic partition (10MB) for grub (ext2)

I have been trying to move away from Windows2000 on Ubuntu for months. I have a few applications that I run on Windows that I have been unable to find usuable equivalents on Ubuntu eg Outlook/Mobile sync application required for my job and a DVB TV card application for home. So it looks like I am stuck ruuning W2K and Linux for at least a while and indeed I have been using GRUB2 to select between W2K and Ubuntu.
I need some basic advice about setting up GRUB2. My philosphy when it comes to PC data is you can never have enough backups and I avoid any single point of failure. So I have always used two hard drives which I keep in sync almost daily with FreeFileSync. I also swap my most critical encrypted data between a laptop and desktop. Then I also alternate external USB drives stored away from my home.
My current partions are
When I installed on the Ubuntu 500GB I let it & GRUB2 take the default options so it boots from Hd1 and I assume certain executables are stored at the begining of the Ubuntu partition as well as configuration files in its file system.
Now I'm replacing the 500GB with a 1.5TB and the old 500Gb will become my backup drive. I want to keep the backup drive bootable in its onw right. If either hard drive fails I want a bootable system and acccess to my data.
So my plan is to use the following partitions.
I can install W2K on the 1.5Tb from scratch or use Acronis to restore an image file. Then I can install Ubuntu from scratch.
OK now for my questions.
1) Can I get GRUB2 to put its executables and configuration files on a small partition of its own? I see no reason why they should be dependant on a specific Ubuntu partition. I have read posts mentioning this but not sure if this has to be a bootable Linux or just a file system with the config files.
2) Can I run update-grub on any Linux and store or copy the config files to the partition in 1?
3) I will use BIOS to determine which hard drive is first to boot. When I run update-grub (or when it runs during the new Ubuntu install on Hd1) I dont want GRUB2 to do anything with Hd2, not even know Hd2 exists, it that an option?

How is this supposed to work out? I noticed some distros are really good about recognizing your other linux distros and some not. They keep recognizing windows, but not other linux distros. Also, I have run into a few problems when my operating systems were on different hard drives. I have my operating systems running from a small 250gb laptop hard drive with special mounting and am using my TB hard drive for internal storage /data.However, my last attempt at installing a linux partition on the TB hard drive with Windows and another linux partition on the laptop hard drive didnt work out so well. Updating grub via the command line didnt sort this out. Sudo su root Apt-get update grub (or grub update) or whatever didnt work before when I tried it.

The RHEL 4 update 7 installation CD installs the kernel with version 2.6.9-78.EL and therefore must contain corresponding vmlinuz and initrd.img. However I would like to have an all modules initrd that is used during installation but for a different version (2.6.9-78.0.13.EL). Is there a way in which I could obtain/make such an initrd?

I've just got a question about this. What if you wanted to change only the display sequence in Grub 2 (Ubuntu 9.10) and not which o/s boots first or is the deault o/s? In previous versions of grub you could just copy & paste the lines in /boot/grub/menu.lst, but this version of grub doesn't allow you to edit /boot/grub/grub.cfg...

So my grub menu is showing several selections for each of my OS's. In Ubuntu, my OS of choice for now, how can I access the grub and edit it.
I would like to know the steps for console, but also I hope somebody can show me how to use Super Grub to do it.

I have a fedora 11 with kernel package: kernel-PAE-2.6.29.6-217.2.3.fc11.i686
I would like to install the devel package for this kernel version, but I can't find it, because in the fedora repo there is only the original kernel (2.6.29.4....) and in the updates repo there is only the newest kernel package (2.6.30....)
Where can I find the packages which are between the fedora and update repos' versions?

I have been reading for hours and just do not get how to do this simple task. I need to add a couple of kernel options to the 3rd menu item that shows in my grub.cfg list. I understand which files to edit (not grub.cfg) and run the updater.
If I look in /etc/default/grub I cannot figure out how to add a kernal parameter unless it is the default.
So basically I want to change the equivilent of this line below:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
But for a kernel menu item that is not the default.

I've had a fairly trouble free dual boot system for about 7 months now, windows vista / ubuntu 10.04 on separate drives. Got a little lazy and had quite a backlog of updates to do in ubuntu so I started up the update manager and let it do it's thing overnight. When I checked in it was waiting for a reboot to finish installing, which I did. When grub came up every selection returned the same error: file not found and must load kernel first, press any key to continue which leads back to the selection menu. Windows still works fine, and with a live cd I can see the the normal file system stuff is still there: filesystem, intrid.img , intridimg.old , vmlinuz , vmlinuz.old... etc.
Tried the live cd terminal to install grub.. grub-setup, grub-install, grub-probe all return the "/usr/sbin/grub-probe: error: cannot find a device for /boot/grub (is /dev mounted?)." line.
Anyway here is the boot info script results.

So I know I should have known better then to turn my updates back on after the 15 and 16 kernel updates crashed ubuntu and grub but I did anyway and once again after a new kernel gets installed I'm stuck at the grub sh prompt.
Been down the road before... tried using
linux /boot/vml....... root=/dev/sda1 loop=/ubuntu/disks/root.disk ro
When I use the 16 or 17 kernel I get an error stating "invalid imaginary number"...
So I use the 14 kernal and enter
initrd /boot/initrd.....
boot
And it boots like it did the last time this crashed. I went to the terminal and entered
sudo apt-get install grub 2
sudo update-grub2
And then rebooted like I did last time expecting the problem to be fixed and at least be able to boot up the 14-generic. It didn't fixed this time. So now what do I do to fix grub and what do I do about having 2 unbootable kernals??

I have not dug into Ubuntu for almost a year now (Since Jaunty, really). I am trying to come to grips with Grub2, but have just now encountered it in Lucid. I am having a terrible time with the graphics chipset, and it may well be that Ubuntu cannot be used on this computer (an older laptop with the dreaded Intel 82845G graphics chip). There are a number of older bug reports that it is unsupported, but some success in more recent versions.
Anyway, one suggestion has been to add i915.nomodset=1 to the kernel boot line. Now, this was a cinch in Legacy Grub, but I have been reading Grub2 wikis and tutorials for two days now, and I know about the config files, but I cannot find anything which tells me specifically how to add a parameter to the kernel boot line.

I have been running Ubuntu 10.04 for a while now without any issues. I have also been dual booting with grub2 for a while now, only issues being crappy customization. But anyways I had my grub2 splash all set up the way i liked, with a nice background and everything. I run every update Ubuntu wants and have never had an issue until recently.
On June 3rd I ran an update that Ubuntu requested, it installed a new kernel (-2.6.32-22) and requested a restart, as usual. after restarting, my grub splash is gone. I thought no biggie ill just run `update-grub` as i have before and it will fix everything...nope
I get the error message `head: cannot open `/boot/grub/video.lst' for reading: No such file or directory` right where the "image found" message is supposed to be.

I have a problem with my touchpad, sometime it doesn't work at start-up and this happens randomly.
I have looked around and maybe I could solve this with the procedure described in [url]
I'd like to add the equivalent of to kopt in the old grub.
I looked into the grub2 documentation, [url]
I am not even sure if I have to modify /etc/grub.d/40_custom or 10_linux.

How do you go about removing old kernel from other distros from the grub menu. For example I have lucid and ubuntu studio installed. Lucid controls the grub2. So how would I remove the old kernel out of the ubuntu studio?

In my /media directory, there is a sub-directory that doesn't point to any drive (mounted or unmounted) - when I look at it in nautilus, it looks like a folder with an x on it, and I can't actually get inside the folder through the terminal. It has the same name as an external hard drive that I used to own, but has since been repartitioned. I think that, at one point, the drive was removed from my computer without unmounting, and its listing in /media was never removed (I left my home for a weekend and when I got back the drive didn't work and this listing was there in /media. I think my roommate might have done something to it, but he hasn't admitted to anything). Is there any way to remove this listing?

I've been using Ubuntu since 7.10 Gutsy Gibbon. I only recently fully switched to Linux OS's, and Ubuntu is now my primary. I currently have 9.10 installed. CURRENTLY I also have Backtrack 4, and Fedora 12 (Ugh!).Previously, I thought something was wrong with my my filesystem in Ubuntu 9.10, and after an upgrade of the linux kernel, I started to get Error: You need to load the Kernel First. That's where my problems started. I had upgraded to 9.10 from 9.04 and I still had Grub Legacy, so I went through hoops to try and get it to work, but eventually everything just kind of broke, and I completely wiped off my partitions on it and started fresh installs of all 3.
And now that the new linux kernel is released, 2.6.31-20 generic (I think... That's what the highest number on a file I can find in /boot is)I went through a few more hoops and ladders and tried to get it to work, but to no avail. I've looked the internet for a solution to this and tried just about everything but there is no unified answer, and I've seen on Launchpad there are alot of bugs that are classified as 'Fixed', but the problem still remains.I took out the 'quiet splash' part in the GRUB2 line for the newest kernel and it didn't do anything. It only changed it to "Error: Couldn't find file".This is the top two kernels (Main and Recovery for the new, and Main and Recovery for the previous working one)

So I currently have an Ubuntu/Mandriva/PCLinuxOS multiboot setup on my system. After I installed the latter two I setup Ubuntu's grub2 to be my default boot manager. After running my Code: sudo update-grub command it successfully found and added entries for Mandriva and PCLinuxOS, however upon trying to boot into either of these distros (selecting them from the menu) I get some terminal output that ultimately ends in kernel panic.

I need to test my code under different versions of GCC. At leat GCC 3.4 in addition to the default. I was hoping I could simply do the switch from CodeBlocks's build settings... Of course, it's not that simple.
By the way, GCC 3.4 is not even in synaptic manager. I suppose some apt-get install command can do it.
ideally I'd like to be able to switch between versions. I've heard of ccontrol, but I'm cautiously posting here before for any advice before blowing up my set up.

I have (after upgrading from 9.10 to 10.04) several packages who are installed with multiple versions.
e.g. Python
dpkg -l | grep python2
ii libpython2.6 2.6.5-1ubuntu6 Shared Python runtime library
[code]....
I guess I only need the newest one .. The other ones have status "RC" Or am I wrong here, and do I need to keep these old versions ?So how do I get rid off 2.4 and 2.5 and just keep version 2.6.How can I easily remove these "old" packages. I tried aptitude purge, aptitude clean, aptitude autoclean. But they don't do the trick.I am looking for an easy way, because python is only an example. Else I could just delete them be using their name.... (of course)
