[SOLVED] LILO partition not found in GRUB bootloader.

NewbProgrammer · 07-08-2017, 10:26 PM

So I recently installed the killx.linuxbbq.org distro (it comes with LILO as its default bootloader). I have two hard drives, three partitions--including killx--OpenSUSE with GRUB on /dev/sda1 (and on MBR). Devuan with GRUB on /dev/sdb1, and finally, killx on /dev/sdb2. I *must* have GRUB on my MBR--I can't afford to have LILO as an alternative, *no exceptions*. I modified my lilo.conf, and updated GRUB on my host system by running: update-bootloader && grub2-mkconfig
After I rebooted, the partition was nowhere to be found.

My lilo.conf:

#
# minimal LILO configuration
#
lba32
append=" vt.default_utf8=0"
boot = /dev/sdb2
prompt
timeout = 30
change-rules
reset

image = /boot/vmlinuz
initrd = /boot/initrd.gz
root = /dev/sdb2
label = Linux
read-only

Then I ran /sbin/lilo:
Warning: '/proc/partitions' does not exist, disk scan bypassed
Warning: /dev/sdb is not on the first disk
Fatal: Trying to map files from unnamed device 0x002b (NFS/RAID mirror down ?)

So I changed to boot = /dev/sda, and the same output as above appeared.

Any help is appreciated. This is the FIRST time I've ever used LILO.

If you have Grub on the MBR of sda and nothing in the MBR of sdb, you will need an entry in the Opensuse grub.cfg file for the new OS. Modifying Lilo isn't going to help if all you have is Lilo on the partition, you need to get to it from Opensuse first and you don't actually need Lilo if you have Grub in Opensuse. What output did you get when running grub-2mkconfig from Opensuse?

I am very new to modifying GRUB. And in this case, I have no idea what to do next.

Did you follow the instructions at the killx site below?

http://killx.linuxbbq.org/docs.html

The only reference to it in your grub.cfg file is:

Quote:

Found killX 0.1b (Nietzsche) on /dev/sdb2

which is at the end of your menuentries. Have you tried just putting a chainloader entry in the Opensuse grub.cfg file and rebooting to test. If you put it in grub.cfg, don't run grub-mkconfig but reboot to test and if it fails just delete it and if it works, put it in /etc/grub.d/40_custom. Is this an MBR system? I've never heard of killx so you would need to see if there is a boot directory and kernel on sdb2. If so, the chainload entry should work. If not, good luck.

Yes of course I followed the killx installation guide! If I hadn't chrooted into it, I wouldn't have shown you the lilo.conf.

I put

menuentry "killx" {
set root=(hd1,1)
chainloader +1
boot
}

in /etc/default/grub and ran grub2-mkconfig:

/etc/default/grub: line 45: menuentry: command not found

Yes of course I followed the killx installation guide! If I hadn't chrooted into it, I wouldn't have shown you the lilo.conf.

what commands did you use to chroot into the killx installation? looks like might be missing some files in /proc when you chrooted into your system.

Did you not think that message was a little odd since you have a number of "menuentry" lines in the grub.cfg you posted?
Why exactly did you put it in /etc/default/grub when you were explicitly told to put in in /etc/grub.d/40_custom?
Might be helpful to read a little more carefully in the future.

I copied /proc/partitions over to my killx session and reran /sbin/lilo, the complaint disappeared but the two other lines stayed.

Commands after first chroot:

passwd
nano /etc/hostname
nano /etc/fstab https://www.zerobin.net/?201b8e37baa...K3cHIqa/HiQjo=
nano /etc/mtab https://www.zerobin.net/?4b2c83743f8...lg30ag3pgPXrA=
dhcpcd
nano ~/.bashrc
nano ~/.bash_profile
nano /lilo.conf
/sbin/lilo

I added the menuentry chunk to /etc/grub.d/40_custom and updated GRUB. Rebooted, killx showed up in the menu. Couldn't boot into it because of no kernel parameters. Any idea on what parameters to put in? Which file to put in? /etc/grub.d/40_custom? /etc/grub.d/41_custom?

Thanks in advance.

EDIT: I see, are the parameters supposed to be in /etc/grub.d/30_os-prober?

Copy the kernel parameters from another entry, and customize them for the different disk location. In the kernel line there is a root= entry. You can use a UUID or a device node like /dev/sdb1.

colorpurple21859 · 07-09-2017, 08:47 PM

did you run the following commands to chroot:

Code:

mount --bind /dev /mnt/dev
mount --bind /proc /mnt/proc
mount --bind /sys /mnt/sys
chroot /mnt /bin/bash

this is assuming killx is mounted at /mnt .

I mounted the necessary filesystems, no noticeable change in anything.

I added modifications to my /etc/grub.d/40_custom

#!/bin/sh
exec tail -n +3 $0
# This file provides an easy way to add custom menu entries. Simply type the
# menu entries you want to add after this comment. Be careful not to change
# the 'exec tail' line above.
menuentry "killx" {
set root=(hd1,1)
chainloader +1
boot
linux /boot/vmlinuz-huge-3.10.9 root=/dev/sdb2 #it exists
initrd /boot/initrd.gz
}
# EOF

I updated GRUB and rebooted into killx, it said /boot/vmlinuz-huge-3.10.9 does not exist and I need to load my kernel. So it didn't boot.

I have no idea what I'm doing wrong. Please help.

If you are going to put kernel and initrd lines, you don't want the chainloader entry, try the entry below, if the hugh kernel exists in the boot directory, hopefully it will boot:

Code:

menuentry "killx" {
set root=(hd1,1)
linux /boot/vmlinuz-huge-3.10.9 root=/dev/sdb2 #it exists
initrd /boot/initrd.gz
}

The boot parameters are generally on the kernel line in grub.cfg, the line beginning with linux. I have no idea what parameters this OS would want and their site doesn't have much for documentation. Did you get a message regarding parameters when you tried to boot? If so, what exactly was it?

NewbProgrammer · 07-09-2017, 10:38 PM

I removed chainloader, updated GRUB, and rebooted. I still get the same output:

error you need to load the kernel first
error /boot/vmlinuz-huge-3.10.9 does not exist
error you need to load the kernel first

Hi, I think the series of lines which yancek gave you lead to the correct solution. You are getting the error because maybe you need to modify the path to the kernel and also check if you have the initrd.gz at that location.

So, mount your killX partition and check the paths:

Code:

menuentry 'killX' {
    set root='hd1,msdos2'
    linux PATH_TO_YOUR_KERNEL root=/dev/sdb2 ro
    initrd PATH_TO_YOUR_INITRD
}

I used 'hd1,msdos2' for killX based on the entry for Devuan, since you said Devuan and killX are on the same hard drive.
If you don't have an initrd there and if the kernel is not a "huge" one, you will have a kernel error at boot, but at least it will start to boot. Then, you just have to chroot into killx and make an initrd.

I followed your steps. Updated GRUB, rebooted. Killx gave me a kernel error. It booted. While I was in the environment, I couldn't type anything because there was no active kernel present. In dmesg, there was an error saying /sbin/init does not exist. How do I create an init? I do have sysVinit on killX, it's just not doing anything. Should I remove the existing kernel in /boot and compile my own?

EDIT: Never mind, I'm going to mark this thread as solved because this is on a different topic now.

Thank you very much.
