    Help with grub.

    hello guys, it's been nearly 2 weeks now since i have managed to boot directly to Kubuntu. I've had 3 different grub errors over this period (15, 17 +22) I am now back to error: 15 file not found.

    i have searched the forum and tried to follow the howto's, i also have the SuperGrubDisk which tells me it's repaired Grub, yet in a week of using that disk i have only managed to boot once.

    i have 2 hard drives, one with 3 partitions, the other has a single partition. i don't have windows installed, i made a complete switch about 2 months ago.

    if anybody can help me fix this problem I'd really appreciate the time and effort. thanks

    Re: Help with grub.

    You should post your boot menu for us to see. That will be the file /boot/grub/menu.lst in your “main” OS—the one that controls the boot menu, and the one from which you installed GRUB lastly.

    Where did you install GRUB to? The MBR of the first bootable hard drive?

    For now ---

    “File not found” is many times caused by a typo or an incorrect device reference.
    So, in that “main” /boot/grub/menu.lst, look at the boot entries – look at the boot entry corresponding to the OS you tried to boot when you got that Error 15.
    Now, examine 3 statements there:
    root
    kernel
    initrd

    Look for typos, misspellings, and look at the root (hdx,y) statement—Does it look right? Is that the proper device reference where the kernel and initrd statements are to be found?

    GRUB is looking for one of those files (kernel or initrd), based on what the menu.lst says, and GRUB can’t find it exactly where the menu.lst says it should be.

    To get more help, try to give us more information.
    What OS did you install lastly?
    What’s your menu.lst look like, especially the “bad” statement causing the error?

    I’ll be in an out this p.m.., but many of us have been down this road!

    (P.S. This is a very solvable problem, so not to worry (too much)!)

      Re: Help with grub.

      Hello mike. here is my menu.lst

      ## ## End Default Options ##

      title Ubuntu, kernel 2.6.20-15-generic
      root (hd0,0)
      kernel /boot/vmlinuz-2.6.20-15-generic root=UUID=19572df0-c05d-422f-bc3f-851e65c00ad7 ro quiet splash
      initrd /boot/initrd.img-2.6.20-15-generic
      quiet
      savedefault

      title Ubuntu, kernel 2.6.20-15-generic (recovery mode)
      root (hd0,0)
      kernel /boot/vmlinuz-2.6.20-15-generic root=UUID=19572df0-c05d-422f-bc3f-851e65c00ad7 ro single
      initrd /boot/initrd.img-2.6.20-15-generic

      title Ubuntu, memtest86+
      root (hd0,0)
      kernel /boot/memtest86+.bin
      quiet

      ### END DEBIAN AUTOMAGIC KERNELS LIST
      i think kubuntu should be installed on hd0.1. not hd0.0 as menu.lst says.. (is there a way to check this using the LiveCD?)

      my last install that booted was kubuntu 7.04 - which i upgraded to 7.10 using Adept, rebooted and everything was fine. after shutting my computer down normally, i returned from work the following day and that's when my grub problem first started. I have reinstalled kubuntu 7.04 another 4 or 5 times since then.

            Re: Help with grub.

            Is that the whole of your menu.lst file or just the end of it? Because if that is the whole file then there are huge chunks missing.

              Re: Help with grub.

              Your “main” Kubuntu is the one on sda1? – The first hard drive, the first partition?
              If so, that is (hd0,0), so that looks OK.
              (GRUB counts hard drivse hdx and partitions starting from zero; so (hd0,0) is hard drive 0, partition 0 – the first hard drive, the first partition.)

              This one, right? – Is this your “main” Kubuntu? On hda1? This is the one that gives you “File not found”? --

              title Ubuntu, kernel 2.6.20-15-generic
              root (hd0,0)
              kernel /boot/vmlinuz-2.6.20-15-generic root=UUID=19572df0-c05d-422f-bc3f-851e65c00ad7 ro quiet splash
              initrd /boot/initrd.img-2.6.20-15-generic
              quiet
              savedefault

              I’m assuming we do not have to re-install GRUB here.
              If we do, and if THAT (above) is your “main” Kubuntu, then it will NOT hurt to do so, and so do it as follows:

              Open K-Menu > System > Konsole (use a Live CD if necessary)
              then type
              sudo grub
              press <Enter>
              type at the grub> each of these, followed by <Enter> after each:

              grub> root (hd0,0)
              grub> setup (hd0)
              grub> quit
              $ exit

              then re-boot to test it.


              If this is your Kubuntu giving you problems:

              title Ubuntu, kernel 2.6.20-15-generic
              root (hd0,0)
              kernel /boot/vmlinuz-2.6.20-15-generic root=UUID=19572df0-c05d-422f-bc3f-851e65c00ad7 ro quiet splash
              initrd /boot/initrd.img-2.6.20-15-generic
              quiet
              savedefault

              then, as Snowhog is getting at, you need to make sure that the UUID string 19572df0-c05d-422f-bc3f-851e65c00ad7 is correct.
              You can check your UUIDs as follows (commands to type at Konsole):
              UUIDs, listing:
              From Live CD and HDD: ls /dev/disk/by-uuid/ -alh # these are “ell’s” as in the word “list”
              From HDD only: blkid # same here, “l” as in “list”


              You are using 2.6.20-15-generic and not using 2.6.20-16-generic, right? (I’m thinking I have -16?) If you look under /boot in Kubuntu, do you see that kernel (vmlinuz-2.6.20-15-generic)?

              I don’t see a misspelling or a comma that should be a period (or reverse), dashes are in place, etc. Sometimes people spell vmlinuz as vmlinux (I have before), but not in your case here. Looks OK to me.


              You can "tag" or identify your Kubuntu by writing something catchy in the title line -- you edit menu.lst as root then File > Save and File > Exit.
              For example, you might change it as follows:
              title My naughty Kubuntu -- Ubuntu, kernel 2.6.20-15-generic

                that is just the end of menu.lst which contained the root,kernel,initrd enteries. if the rest is needed i can post that too

                  We really only need the boot entries for any naughty OSs that are not booting.

                    Re: Help with grub.

                    You have just the one Linux OS -- Kubuntu -- on the first hard drive the first partition?
                    I notice you have a 2nd HDD hdb that looks like it could be partitioned for an OS at hdb1?

                    I also notice that perhaps you have both SATA and IDE hard drives?
                    If so, it really would not hurt (and might help) to re-install GRUB as explained in my post above -- ASSUMING your main Kubuntu is the one shown on sda1.

                        I'm using a purchased livecd with no updates, so me running version 2.6.20-15-generic rather than 2.6.20-16-generic sounds correct.

                        yes, just the one installation on the first partition.
                        hdb has one partition, but there's no OS installed there, i have it mounted now and there are just a few of my personal files.
