Lilo not booting slackware correctly. Errors listed inside.

I'm fairly new to Linux so I'm going to need a step-by-step guide to get me out of this rut. The install of Linux was fine but when I booted up I got this error.

VFS: Cannot open root device "302" or unknown-block (3,2)

Please append a correct "root=" boot option;
here are the available partitions;

0800 78150744 sda driver:sd
0801 47428608 sda1 <-- this is my Windows partition
0802 30719552 sda2 <-- this is my Linux partition
0b00 1048575 sr0 driver:sr
0b01 1048575 sr1 driver:sr

Kernel panic - not syncing:VFS:Unable to mount root fs on unknown-block (3,2)

I guessed from reading this error Lilo isn't pointing to the right partition to boot from? How will I fix this? I read another thread about boot problems on these forums and a guy said to do this:

#mkdir /slacktemp
#mount /dev/device /slacktemp
#chroot /slacktemp
#cd /slacktemp/etc <-- for me it told me that doesn't exist
#vi lilo.conf <-- couldn't do nothing and was frozen
#lilo -v -t -b /dev/device
#lilo -v -b /dev/device

The above solution did not work for me. Can anyone shed a light on a Linux rookie?

put the output of

# cat /etc/lilo.conf

for this simply mount the /dev/sda2 on /mnt then use the command.

for mounting use

#mount /dev/sda2 /mnt

also put the output of

#fdisk -l

I think things just got interesting W34p0n-X. First off, thanks for the speedy response. These are the results from my last adventure.

#cat /etc/lilo.conf

cat: can't open '/ect/lilo.conf' : No such file or directory

#fdisk -l

Well... I guess those commands shouldn't work quite right. Can you try the following:

Code:

mkdir /slacktemp

mount /dev/hda2 /slacktemp

(/dev/hda2 is your Linux partition, isn't it?)

Code:

ls /slacktemp/etc

(this command must show you a list of files, not an error - if it does not, something gone wrong)

Code:

cd /slacktemp

mkdir -p dev proc sys

mount --bind /dev dev

mount --bind /proc proc

mount --bind /sys sys

chroot .

vi /etc/lilo.conf

Have you ever used Vi? It's not as simple, nor it is a rocket science. After you're entered this command, press 'i'. Now you're in the insert mode. You can insert, delete or change your text in this mode as usual.

Find the section which loads your kernel. Something like:

Code:

image = /boot/vmlinuz

    label = Displayed_Name

    root = /dev/hda1

Here '/dev/hda1' (may look different) is the device the kernel tries to mount as a root file system. Delete it and replace it with /dev/hda2. Add a line with 'root=/dev/hda2' with a few leading spaces if it does not already exist.

Press Esc (it usually works) after you're done with editing. Type ':w' (yes, with a colon), then press Enter. Vi will tell you the file is saved. Then type ':q', Enter. Vi will exit after that.

Code:

lilo -v -t -b /dev/hda2

lilo -v -b /dev/hda2

The first of the above commands may check if anything goes wrong without actually modifying anything. If anything is allright you may issue the second one. It will make Lilo write a boot sector to Linux partition. You may also do something to make your Windows boot loader boot from Linux partition, but it's just another story :)

After all above actions are performed, a few commands are left:

Code:

exit

umount dev proc sys

cd ..

umount slacktemp

The error you are getting

cat: can't open '/ect/lilo.conf' : No such file or directory (check the filename here,it's /etc/lilo.conf not the /ect/lilo.conf)

use the correct syntax and post the output

#cat /etc/lilo.conf

Alright Prehistorik, I'll be back shortly with results.

Hi,

:hattip:

vi has shown me
image = /boot/vmlinuz
label = Linux
root = /dev/hda2

so it is pointing to the right direction. also to the people saying that i actually typed in mounting on device i didn't, i did it correct lol.

Also I'm about to post that output of lilo.conf for you weapon.

Uh no matter how I spelled it it doesn't exist it says.

Any new suggestions?

Did you do a full install?

Did you install lilo in the install sequence.

I would boot using the install DVD, following the instructions on the splash screen, then as root install lilo. Then run lilo. Then reboot.

samac

yeah i did a full install and installed lilo after it was done like it guided me too. let me try this again then.

Did you install to the MBR?

samac

Yes. I'm about to just quit on slack and lilo. Probably the worst bootloader I ever dealt with. I have installed Gentoo easier than I had with slack and Gentoo is a horrid distro that breaks with every update. Can I installed GRUB and make this work? Lilo seems to be the worse damn bootloader I have ever dealt with.

Lilo is wonderful, it is elegant and simple and works, but if you are happier with grub you can install it. I would however point out that grub is a 32-bit program and you will have to install 32-bit extensions if you are using Slackware64.

Best of luck with whatever you choose.
