Ubuntu :: How To Make Update-grub (grub2) Ignore Other Partions / Distros
Jun 9, 2011
I generally have at least 4-5 distro's installed at one time - I always install grub to the boot partition of other distros -that was I control grub from the individual distros - I use ubuntu's grub as the default boot loader.
Rather than the method that ubuntu uses with the update-grub.I normally edit the grub.cnf file to add other distros but when update-grub launches it also adds links in grub.How can I prevent the upadte-grub script automatically adding lines for other distros i.e - I just want it to add ubuntu entries and ignore other partitions.

My kupdate-applet tells me it has a recommended update: KDE 4.3.5 from the official opensuse update repo. Problem is I already have a more recent version of KDE 4.3.5 installed from the official opensuse KDE repo. In yast I pressed the "switch system packages" button for the KDE repo. How can I make the update applet ignore this "recommended" update? Note that the updateApplet itself is installed from the opensuse update repo. If I don't do this, then the older update applet from the KDE repo always has a recommended update for... Kupdate-applet.

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 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.

Difficult problem of booting due to the presence of 2SATA hdd (sda,sdb) and 2IDE hdd (sdc,sdd). At the moment I have kubuntu-karmic on sda booting itself and bothe win7 and xp on the same hd. I edited, the custom grub.d file to add Suse and Mandriva installed on sdc and generated a new grub.cfg. Neither the entries grub2 finds by itself nor the ones generated by my files start. No error of sort. I select the entry and nothing happens....it just hangs.I had hoped to have solved the problem of booting as grub legacy installed itself on the wrong disk/partition and never found its stage 2.
i copy here grub.cfg
Code:
#
# DO NOT EDIT THIS FILE
#
# It is automatically generated by /usr/sbin/grub-mkconfig using templates
# from /etc/grub.d and settings from /etc/default/grub
[code].....

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.

When I first started using Unity, I configured the dual monitor system under the settings program. I then changed my xorg.conf, but Unity is ignoring that configuration and switching to its own. I think this might have something to do with RandR, but I'm not sure. Is there a way to make Unity use the xorg.conf configuration?

if there is a way to blacklist certain packages when updates come around. The reason for this is that I have two repositories that contain Smplayer and Mplayer. But one repository versions of this aren't VDPAU active (but the build is newer).

Is there a way to force rsync to not make directories in its destination directory; ie, to simply dump all of the files from the source directory directly into the destination without copying any of the folders that the files were originally in? I tried --no-dirs, but that seems to only be for empty directories.

I just upgraded my storage server to maverick and it seems the 2.6.35-25 kernel doestn like the hardware im using
since im pretty sure its a hardware related problem and the previous kernel hastn the issue im currently booting this old kernel everytime i need the server by hand (using Shift during boot for the grub menu to appear)
well, it narrows down to the following question:
how can i exclude a specific grub entry - in my case the current kernel 2.6.35-25 - so only previous kernels OR future kernels from the next updates will have a chance to boot?

I'm using andLinux and for whatever reason, emacs seems to think that the file I'm editing has been changed every time I try to edit/save and keeps reprompting me. Very annoying. Is there a way to make emacs stop checking the file on the disk?

when I have a broken packages on the system and want to apt-get install something (completely unrelated to the broken package) apt-get starts giving me crap about the broken stuff and won't download and install the packages I'm asking for. How can I make it ignore the completely unrelated stuff about missing deps on my system and download what I want?

Short version: Why does apt-get update since recently ask me for my installation DVD?
Long version: In my sources.lst there is still an entry for the installation DVD.
I like that because if a package on DVD is still the newest version then there is no need to download it again. (If I comment out the DVD entry apt-get update will ignore the DVD but at the same time no package will ever be installed from it again, right?)
Since some time ago this was no problem as apt-get update didn't have a problem with the entry - or if it had (I don't really remember), there was just an error message and the process would continue with the other sources. But then this changed and now I'm asked to insert the disk (luckily I have only one DVD) every time and the routine waits until I have done so.
Is there a way to change that back?
I've read some apt documentation and the apt-* manual pages including apt.conf and some examples for that but could not find something useful though there might be something I missed because I didn't understand everything I saw.
Clearly, it makes sense that DVDs and the like can be included in apt-get update because some people update offline with these media. But (the standard) DVDs are read-only and the individual disks are identified by apt (see /var/lib/apt/cdroms.list). So the system should not expect an already known DVD to change but recognize if a new one is being used.

I am trying to run Ubuntu 9.10 from a USB drive on an old laptop with a dead hard disk.An added complication is that it does not support USB boot, only CD boot.So with the help of URL..., I am running grub from a cd and then booting the kernel from the USB (or something like that).
The problem is that after I do this, I get about 6 minutes of error messages as the kernel tries unsuccessfully to read my dead hard disk ("buffer I/O error on /dev/fd0" or something like that). I can post again if the specific error message would be useful. (But it takes so long to reboot that i'd rather not). I can tell it is trying to access my hard disk as I hear the disk occasionally spinning (it intermittently spins and does not spin). After many failures, the system successfully boots and runs from the USB drive.I tried removing the hard disk from the machine entirely, but this triggers an ASPI error and the kernel hangs.So ideally I would like to modify the kernel command line above to instruct it to ignore the hard disk. I read some kernel documentation but it proved a little bit too advanced for me.

When I installed 10.10 I uninstalled gwibber, empathy and ubuntuone. Twice now in Update Manager I've subsequently found gwibber on the list of possible updates. Is there a way to tell Update Manager not to include in future some programs, which I've uninstalled and don't want?

I have 2 distros installed right now and generally keep the main one and install and look at other distros.My question is this; Can I install a second distro and not let it take over my frub/boot menu and NOT let it control the boot menu? If so how would I do it? I always get confused when I install the second distro when it asks what to do,use / or boot as the option etc...

It's a little silly to ask this, as I am about to try it anyway, but is it theoretically possible to use a GRUB Legacy USB boot cd to boot a distro beyond 9.04? Or do I need to get to reading about GRUB 2?EDIT: As the USB Boot CD needs to be created from the GRUB files existing inside the Distro that it is intended to boot, this is impossible. Question answered.DIT EDIT: Unless I revert to GRUB legacy inside the Distro itself. Ok. Neat. I guess I just needed a place to write it down to figure it out

I'm trying to make my own boot CD with different linux distros and tools. These are the things I'm going to include on the CD:Lucid Puppy 5.11 (Live)Damn Small Linux (Live)Gparted LiveArch linux net install(Total size: about 600 MB)I was thinking about using GRUB legacy as the boot manager on the CD, but I'm wondering how I can install GRUB to a CD. I've been experimenting with the live CD of Ubuntu, but when i start to delete the Ubuntu files (which I don't need) it messes up the filesystem manifest and I'm left with a non-bootable .iso. So I want to build GRUB from scratch and add all the entries to the menu.lst.

I currently am in an adventurous phase and want to try other distros while still having a reliable, stable Ubuntu installation to fall back on. I'm currently in the process of partitioning my disks, and I realized that I might have trouble booting them, as the most recently installed would control GRUB and clobber any previous GRUB setup. So what I want to know is how to go about managing everything so that only one distro, preferably Ubuntu, has control of the GRUB menu at boot up, and will still recognize the other distros on other partitions.
I plan to have three 15GB root partitions, one swap, and one home partition for each distro.
Would I create a /boot for each distro? Or create one /boot with files from each distro copied there? Or should I do something else entirely?
I just don't want the distros to interfere with each other. Also, I don't want to use VMs for this, because I want to see what a real full-performance install is like for each distro.

Would like to try multi-boot different distros other than the Ubuntu flavors, they must use grub boot loader automatically. I cant find any list on the web? I don't want to edit menu.list.

got four partitions, one for media storage, one with ubuntu 9.10 32bit, one with crunchbang lite 9.04 64bit and one swap partition. The partition with ubuntu has been formated from ext4 to fat32 (with nothing on it, obviously). Whenever I boot up the pc now, I get an "unknown filesystem" error and a grub rescue> prompt. When I try to boot up a live usb image from my usb stick I either get a "linux kernel not found" message (crunchbang lite 32bit) or "initial menu has no LABEL entries!" error (gparted live usb) which changes to "Could not find kernel image: vesamenu.c32" after a couple of seconds. save my media partition or, more importantly, my crunchbang lite partition (which has one single important file on it, I'd love to recover). If this is somehow not possible, then I'd at least like to get my system usable again by succesfully booting from usb. I'm fairly new to using linux. I tried some grub-rescue commands, but not even the "help" command worked,

I have used the following
Code: #Don't change this comment - YaST2 identifier: Original name: none# title Ubuntu 10.04 booting via symlinks kernel (hd0,6)/vmlinuz root=/dev/disk/by-id/ata-ST9500325AS_6VE3ZHX6-part7 ro quiet splash initrd (hd0,6)/initrd.img for Ubuntu for some time. Can this symlinks-booting technique (with the appropriate partition numbers/names) be used for LinuxMint and/or Fedora ?
Currently, I have one PC with Ubuntu's GRUB2 managing multiple distros (openSUSE 11.3 and 11.4, Ubuntu, Linux Mint and Fedora) with Windows 7. I would like to replace it with the openSUSE GRUB, and the Ubuntu, LinuxMint and Fedora are rarely used.

Noobish question on multibooting multiple Linux distros. I have four of the current major Linux distributions. Each has been installed and run individually (no other Linux distribution installed) in a dual-boot configuration with Windoze. No problem.
What I want to do is install all four Linux distributions and multiboot them. Reading the internet it would seem this is a simple task with GRUB. The short version being - install a Linux distro with a separate /boot partition for GRUB and use GRUB to boot the other Linux distros from the GRUB boot menu.
So I installed one of the Linux distros with a separate partition for /boot. The distro installer installed GRUB in /boot and correctly setup a dual-boot configuration with Windoze. GRUB was installed to the MBR. Next I installed a second Linux distro in its own root partition and told the distros installer NOT to install GRUB to the MBR, but rather, to the boot sector of the root partion of the second Linux distro. Installation was uneventful (and I could access the second Linux partition from the first installed Linux distro, things looked ok). Then I added to following to the installed (MBR - /boot) GRUB's menu.lst:
Code: title lixux distro 2
root (hd0,7)
chainloader +1 After which I rebooted the system and the new entry for the second Linux distro now appears in the GRUB boot menu. I selected the second Linux distro from the boot menu and got the following GRUB error: Error 5 : Partition table invalid or corrupt
