Error 15 problem - other posts don't seem to help me

Re: Error 15 problem - other posts don't seem to help me

And, to give you more of an idea what to look for, along with UUIDs, as Fintan said,
here's an entry from one of my menu.lst's (typical):

title Ubuntu 7.10, kernel 2.6.22-14-generic
root (hd1,6)
kernel /boot/vmlinuz-2.6.22-14-generic root=UUID=6f00b506-7174-4f0e-8f33-9baaf0293c9a ro quiet splash
initrd /boot/initrd.img-2.6.22-14-generic
quiet

Of course, the (hd1,6) must be correct.
But, also, and especially since you just got an update that caused this, the two files vmlinuz-2.6.22-14-generic and initrd.img-2.6.22-14-generic must both be there and they must be in the /boot directory (or folder) on (hd1,6) = sdb7, exactly that way, as written in menu.lst -- OR, you must change menu.lst to match what really is your kernel & initrd files.

Re: Error 15 problem - other posts don't seem to help me

I have a "Disks and Filesystems" in the advanced tab of my System Settings, not Harddisks and Files as you showed. If I get into admin mode for HDA2 (there is no SDA2) I can't enable it because there is no Mount Point. I can make a New mount point but I dont think thats what you want me to do.

I have a Media directory but it is empty,.

If I use Dolphin and look at HDA2 it says it is Type unknown, size 0 Bytes.....? WTFO

I noticed when I shut down Live last night it said SEGMENTATION FAULT FAIL

is that normal?

Live CD
K > System Settings > Advanced > Disk & Filesystems
Administrator Mode
Right-click on hda2
Modify
Mount point: /media/hda2
Create it? Yep.
Click Writable box
Mount Permission (drop-down list): Any user at any time
OK
Back on main screen highlight hda2, then (at bottom) Enable
Exit out
Konqueror
Storage Media
hda2—click it to open it
/boot, then grub, then, menu.lst
copy/paste here just the stuff after *** Begin Automagic Kernels List

----------

Segmentation fault: just means a bug/error in some program; may be related to problems unmounting upon quitting. Don't worry about that. Best not to get them, but I (and others) get them all the time; usually no serious effects.

Re: Error 15 problem - other posts don't seem to help me

Well, the UUID are right for hda2.
And menu.lst looks OK.
Hmmm....

So, now, in hda2, under /boot, do you actually have two files called:
vmlinuz-2.6.22-14-generic
initrd.img-2.6.22-14-generic

And, when you turn on the PC, what do you see? what happens? Do you get a boot menu, then select Kubuntu, then you get Error 15?
What about Windows? you can boot into it ok, or not?

Re: Error 15 problem - other posts don't seem to help me

evans62, in case I get pulled away here for awhile, and if you have not seen anything else that's suspect yet, I'll drop this off as another idea ...

You're going to think I'm off the deep-end with this one...

You can try to manually re-type the main boot stanza entry for Kubuntu—Just to see if we can make it work that way. Do NOT copy paste it from any word processor or from any text editor – please type it the old-fashioned way. (Many times, I've had seen this work, including for my personal work with menu.lst)

Use the Live CD, access /boot, click grub, right-click menu.lst, Actions > Edit as Root, then keep your old lines but put a comment sign in front of each one (#) and re-type each one, the root, the kernel, the initrd lines, and when done File > Save and File > Quit:

title Ubuntu 7.10, kernel 2.6.22-14-generic
# root (hd0,1)
root (hd0,1)
# kernel /boot/vmlinuz-2.6.22-14-generic root=UUID=f5e99e88-803e-45f9-8aea-a50c206fbc33 ro quiet splash
kernel /boot/vmlinuz-2.6.22-14-generic root=UUID=f5e99e88-803e-45f9-8aea-a50c206fbc33 ro quiet splash
# initrd /boot/initrd.img-2.6.22-14-generic
initrd /boot/initrd.img-2.6.22-14-generic
quiet

(Lines starting with # are ignored by GRUB as comments.)
(After the commands root, kernel, and initrd you need at least one space. Every character must be exact.)

I don't yet see anything wrong with menu.lst, given your fdisk -lu output, the blkid, and you checked in the /boot directory for the actual files (kernel & initrd), right?

[evans62]

Re: Error 15 problem - other posts don't seem to help me

Yes, I turn on the PC, I get the boot menu, if I choose either 7.10 or 7.10 recovery mode, I get the Error 15.

W98 boots OK.

In /boot, I have

initrd.img-2.6.22-14-generic.bak, but not another one without the .bak extension, and I cannot rename it to get rid of the .bak

Is that the problem?

[Qqmike]

Re: Error 15 problem - other posts don't seem to help me

Yes that's a problem, big time. I've had it too before.
You need to get in there AS ROOT and do it:
open Konqueror as root:

kdesu konqueror
/boot
then rename it (right-click), File > Save and File > Quit.
I just got a call to go now, but that's it, how to do it, and toad is also familiar with this sort of thing.
Try it -- Hey, you can break anything!
(and toad & I, I think, know how to regenerate/update initrd, if we have to, also)
Re-name it what menu.lst calls it.
Or copy it to a new name (and save the old named file, too, or something like that)
Good Luck.

Re: Error 15 problem - other posts don't seem to help me

I might add, in case toad comes around, that even if/when that works, you should still deal with this issue in a better way (we'll see what happens, and then maybe have you run some initramfs update thingy later).

[Qqmike]

Re: Error 15 problem - other posts don't seem to help me

Here's another way to handle this sort of problem, perhaps the correct way, along with some personal thoughts.

You might want to file this away for the future.
Please do not do this (yet?)--see my notes at the end here:

From the Live CD, chroot into the hda2 partition.
Issue the following command:
sudo update-initramfs -u -v
and let it run and put things together & right for your initrd.

Note:
To chroot into hda2 from the Live Kubuntu CD at Konsole:
sudo mkdir /media/fixthings
sudo mount /dev/hda2 /media/fixthings
sudo chroot /media/fixthings
(Now you are “in” hda2 as root and can work from there as if you were actually booted into it.)

Note:
If the update-initramfs does not work, or hangs, you would try to repair initramfs-tools:
First, from Konsole, uninstall it, then re-install it:
sudo dpkg –configure -a
sudo apt-get –purge remove initramfs-tools
sudo apt-get install initramfs-tools
Then, try the update-initramfs again (as above).

My opinion only: Don't do any of this just yet.
I would run your Kubuntu as is, without doing all this (yet). Fact is, you probably will not have any problems ever, and if you do, it would be when there is another major update to kernel & initrd (offered through Adept Manager updates). At that time, you could run this stuff, if necessary (which just makes sure everything is hooked up right). Fact is, at some point, you will probably re-install another version of Kubuntu anyway, and start fresh. That's another good reason to keep a separate home partition; so when you re-install, your personal data is not touched. You might want to just file this information for possible future use.
=> btw, when using this method three times, it worked perfectly twice; on the third time, the initramfs tools repair trashed my Kubuntu so bad, I simply re-installed (perhaps a Linux expert could have fixed it, but it looked like major surgery to me, my home is separate, so a re-install was just 30 minutes). All this, fwiw.

==> Please let others weigh in here about this.

Some of these major updates are trashing the initrd file somehow.

Re: Error 15 problem - other posts don't seem to help me

Woo hoo! Got rid of the .bak extension and rebooted and that did it.

I think you can mark this SOLVED.

I learned a lot in this process...at the expense of driving you guys crazy

Kubuntu seems like a good OS, thats why I wanted to try it. This machine is ancient...900 MHz Duron, 1 G memory, and an 8MB AGB video card. Kubuntu runs fine on it. Vista wouldn't have even let me try this!!

What would you say the most essential programs to have are, besides Firefox and Open Office...would like to try some more out. Also how old are you guys, I am a geezin 45 yrs old and have been using Windoze since about 1983...

Re: Error 15 problem - other posts don't seem to help me

Thunderbird email is an app I keep running.

Glad you are up & running. What happened to you was just a fluke, something about this latest major initrd & kernel update; and you saw my post above, so just enjoy Kubuntu.

I programmed on the IBM 360 JCL, FORTRAN IV, and that right there tells you my age Later, on the CDC6600, LISP, PASCAL, lots of sim programming; large-scale ops research stochastic process analysis, on and on. M$ Pro products since 1998, til about 2 years ago -- now I do Kubuntu. I have XP on dual boot, but hardly ever use XP now except to run several virus scanners, PerfectDisk, and CCleaner on it.

Welcome to the board evans62! You'll like the whole Linux trip.

(You are young at 45 ...
Just an old hippie here; impossible for you to drive me crazy )

Here I am and have missed all the fun > Well done once again, Qqmike, for sorting all things GRUBBY And I remember your foray into the initramfs world which, I believe, led to a reinstall

I lost tty1-6 the other day, too. But that was because I fancied I could do my own usplash theme - doh!

Re: Error 15 problem - other posts don't seem to help me

Hi toad. Yep, sometimes it better to just glide and enjoy the ride.
As my plumber keeps telling me, if it's working, let's not fix it.

Re: Error 15 problem - other posts don't seem to help me

Yeah, I missed it to

I was repairing a few f..ked up HD all night long and spent the rest of the day installing :P :P

Now I am going for a beer (veeeery large one)

Anyway congrats
