error 15 persists (solved)

Beetlenut · 2006-01-20 16:00:16

I installed the archck kernel and ran into problems. Therefore, I reinstalled the old kernel, reinstalled Grub, uninstalled the archck kernel but all to no avail. Everytime I try to boot up I get an error 15 message. I have booted up with Knoppix and am online. Any help would be greatly appreciated.

hiower4 · 2006-01-20 17:32:36

Okay...
So the arch kernel did work fine the first time?
Is it the same version this time?

what does

mount

return?
i.e. do you boot the correct partition from grub.

if that's okay, then, are you totally sure which kernel boots? what does

pacman -Q | grep kernel

give you? what about

cat /boot/grub/menu.lst

hope that helped

Beetlenut · 2006-01-20 17:46:01

I used the same kernel I had before I changed. (I used the kernel in cache as I couldn't go on line with this computer last night.) It worked fine and rebooted fine before I changed kernels but changing kernel's destroyed grub. My computer is rather simple with an ide harddrive and it only has Arch on it. hda1 is boot, hda2 swap, and hda3 is /.

mount........./dev/hda3 on / type ext3 (rw)
none on /proc type proc (rw)
none on /dev/pts type devpts (rw)

pacman -Q | grep kernel...........kernel26 2.6.15-2

cat: /boot/grub/menu.1st: No such file or directory

(The menu.1st is in /boot/grub and it looks clean.)

hiower4 · 2006-01-20 18:41:24

firstly, it is l as in L in menu.lst , not 1.

secondly, my mistake, I forgot you currently were in Knoppix, not Arch

Or are you, as you have /hda3 mounted on / ?
in Knoppix, first mount hda1 and hda3.

mount /mnt/hda1
mount /mnt/hda3

then, try

ls /mnt/hda1
ls /mnt/hda3/boot
cat /mnt/hda3/etc/fstab
sudo cat /mnt/hd1/grub/menu.lst

post the output you get from the later commands

hiower4 · 2006-01-20 22:22:04

Well there you have it.

seems you did not have hda1 mounted when you reinstalled the kernel, so it put the files directly in (hda3)/boot/ instead, naturally.

your fstab seems okay even though

move everything from /mnt/hda3/boot to /mnt/hda1 and you should be fine.

mv /mnt/hda3/boot /mnt/hda1

(i hope you don't take offense for me listing simple commands, you seem to find you're way, but others might not)

Notice also, that you can probably have both kernel26 and kernel26archck installed simutaneously, and choose which to boot at boottime. Can't verify it though, as i just get failed downloads at the moment when trying to install, but don't worry, pacman will complain if i'm wrong.
When back in your arch environment, make sure hda1 i mounted (check what <i>mount</i> spits out), and install the kernels.
In menu.lst, add the following:

# (0) Arch Linux
title Arch Linux ck [/boot/vmlinuz26archck]
root (hd0,0)
kernel (hd0,0)/vmlinuz26archck root=/dev/hda3 vga=773 ro
#Somebody verify the following line (not 100% sure which .img should be used)
initrd /initrd-2.6.15-archck.img

good luck!

Beetlenut · 2006-01-21 05:18:23

I moved the boot to hda1 as you wrote. But I still can't boot in. I tried removing the kernel and reinstalling grub and the kernel. (with hda1 mounted) Here is what I have for hda1 and hda3/boot.

ls /mnt/hda1
System.map26archck initramfs-2.6.15-archck.img kconfig26.pacsave
boot initrd-2.6.15-archck.img kconfig26archck
diag1.img initrd26-full.img lost+found
grub initrd26.img vmlinuz26archck
ls /mnt/hda3/boot/
System.map26 grub initrd26-full.img initrd26.img kconfig26 vmlinuz26

ps. I take absolutely no offence to keeping things simple. This is a forum for us to learn. Besides there is a certain sense in which we can only become wise by attention to simple things.

hiower4 · 2006-01-21 09:48:38

Mm, sorry, it was in the middle of the night when i wrote last, didn't see my own mistake...
it should have been

mv /mnt/hda3/boot/* /mnt/hda1

Before you go on you might want to backup your boot, just for safety, (at least if you have some own configuration that you want to save)
e.g.

sudo mkdir /mnt/hda3/root/boot
sudo cp -a /mnt/hda1/* /mnt/hda3/root/boot

You can remedy the earlier move by running

mv /mnt/hda1/boot/* /mnt/hda1/

Beetlenut · 2006-01-21 17:48:13

Well now i get to the busy box screen with umount: /initrd:no such file or directory.

I read the forum and tried to run mkinitrd auto but hwdetect says I have no kernel.

[root@Knoppix /]# mkinitrd auto

hiower4 · 2006-01-21 19:30:27

well, do you actually have /initrd on hda3 ? if not, create it.
what does

pacman -Q | grep kernel

spit out?

Beetlenut · 2006-01-22 05:23:09

grep results:

[root@Knoppix /]# pacman -Q | grep kernel
kernel26 2.6.15.1-2

apropos /initrd on hda3. Do you mean create the directory /initrd on hda3/boot?

My hda1 now has two grub directories...

root@2[knoppix]# ls /mnt/hda1/grub
e2fs_stage1_5 menu.lst minix_stage1_5 vstafs_stage1_5
fat_stage1_5 menu.lst.pacnew reiserfs_stage1_5 xfs_stage1_5
ffs_stage1_5 menu.lst.pacnew~ stage1

fat_stage1_5 menu.lst stage1 vstafs_stage1_5
ffs_stage1_5 menu.lst.pacnew stage2 xfs_stage1_5

Where should /grub be?

ps. Thank you for your patience in helping me.

mpie · 2006-01-22 10:14:44

cure your error 15 by re-installing grub it's the easiest way....

I dont mean with pacman...

i mean with grub-install

you can do this from the install cd or another live disk there is a guide on the wiki

Beetlenut · 2006-01-22 10:33:33

I have been having problems installing grub as well.

[root@Knoppix /]# install grub /dev/hda /dev/hda1
install: installing multiple files, but last argument, `/dev/hda1' is not a directory
Try `install --help' for more information.

This is the last reinstall. The time before I tried
#grub
grub> root...etc

(Sorry I don't know what to name this method of installation.)

My problem now is that I get past the error 15 but only to get into busybox. (see above.) If I knew that this problem is not related to this thread I would start a new one.

mpie · 2006-01-22 10:47:18

if your trying to boot kernel26archck

you need
initramfs-2.6.15-archck.img

if your trying to boot kernel26

you need
initrd26-full.img

Beetlenut · 2006-01-22 11:03:28

I have that....

root@2[knoppix]# ls /mnt/hda1
System.map26 initramfs-2.6.15-archck.img kconfig26.pacsave
System.map26archck initrd-2.6.15-archck.img kconfig26archck
boot initrd26-full.img lost+found
diag1.img initrd26.img vmlinuz26
grub kconfig26 vmlinuz26archck

In my menu.lst I have initrd/ initrd26.img. This worked fine before I tried the archck kernel.

mpie · 2006-01-22 18:58:11

initrd26 is one i have made manually try it with
inited26-full.img

maybe you are missing something...

Beetlenut · 2006-01-22 19:26:01

I tried that too.

bier · 2006-01-22 19:32:40

1. delete all file in /boot "dont delete /boot/grub"

2. rekompile the kernel again.
make clean modules modules_install

3. cp /usr/src/linux-yourkernel/arch/i386/boot/bzImage /boot/vmlinuz26
cp /usr/src/linux-yourkernel/arch/i386/Kconfig /boot/kconfig26
cp /usr/src/linux-yourkernel/System.map /boot/System.map26

4. let us make your own initrd
ls -l /lib/modules/
/sbin/mkinitrd kernel_version=yourkernel-2.6.15.XXX

5. rename the initrd in /boot to initrd26.img

6.reboot & good luck.

Beetlenut · 2006-01-23 14:40:08

I did the following but still couldn't boot up. I did not recompile the kernel however as I am just using a stock kernel.

hiower4 · 2006-01-24 15:28:08

from the end of the initrd linuxrc script (the script actually taking care of everything and booting your system)

ROOT_DEV=/dev/root
mkrootdev /dev/root
echo 0x0100 > /proc/sys/kernel/real-root-dev
mount -t `/bin/fsck -NT $ROOT_DEV | awk -Ffsck. '{print $2}' | awk '{print $1}'` -n -o ro $ROOT_DEV /new_root
pivot_root /new_root /new_root/initrd
umount /initrd/sys
umount /initrd/proc

Let's go customize your initrd.
from http://wiki.archlinux.org/index.php/Ini … itrd_Image:
(DO read the link)

[root@Phychan ~]# cd /tmp
[root@Phychan tmp]# mkdir initrd
[root@Phychan tmp]# gunzip < /boot/initrd26-full.img > initrd.img
[root@Phychan tmp]# mount -o loop initrd.img initrd

then change the lines

umount /initrd/sys
umount /initrd/proc

to

/sbin/busybox umount /initrd/sys
/sbin/busybox umount /initrd/proc

This will use busybox own, inbuilt umount command instead of the external which resides on your harddrive. Then:

[root@Phychan initrd]# cd /tmp
[root@Phychan tmp]# umount initrd
[root@Phychan tmp]# mv /boot/initrd26-full.img /boot/initrd26-full.img.bak
[root@Phychan tmp]# gzip < initrd.img > /boot/initrd26-full.img

hiower4 · 2006-01-24 15:31:35

You should not cross post. That is plain rude. Especially if you do in no way point the old thread to the new one. Those things make people work extra you know.

Beetlenut · 2006-01-24 17:17:14

I started a new post because I thought the problem was isolated. In the past i was told if the thread changes I should start a new thread. To my, admittedly inexperienced thinking, the problem had to do with Grub and not changing the kernel. However that maybe it seems I erred and thus I apologize for creating extra work.

I do thank you for your time in explaining all this very clearly. Now i know a good bit more and if I run into similiar problems I will be able to solve them. It is much more useful than try this or try that.

Beetlenut · 2006-01-24 17:19:28

I thought I had posted a link to the new post. Again, my apologies. There is nothing to say about this except I humbly acknowledge my error.
