Reg lilo.conf changed and system doesn't boot

Reg lilo.conf changed and system doesn't boot

[SATHISH.J]

Hi,
I know that this is not the place to ask this question.Please forgive me.
I changed the lilo.conf on my machine(redhat 2.2.14-12 kernel) and it
doesn't boot up. I don't have
a boot floppy to boot. I have another disk which has an older version of
linux(2.2.6). I can mount the disk if I boot from the other
disk(2.2.6). Can I
in some way alter the lilo.conf of my disk(2.2.14) and boot linux from
that. Please tell me any ideas to do that.

Thanks in advance,
Warm regards,
satishj

Hello..

Seems you have installed a new kernel and not called lilo before
reboot...

I would suggest one of these two ways:

-Boot from your older hdd and mount the new one, e.g. under /mnt/test.
Call lilo, but give him the configfile from your new hdd, it should ly
under /mnt/test/etc/lilo.conf, if you have mounted your new, defective
linux under /mnt/test: "lilo -C /mnt/test/etc/lilo.conf
Before, check that your lilo.conf is correct!
(I have to admit that i' ve never tried this myself)

-Boot from your older hdd and use the distro-tools to produce an
"emergency repair disk", e.g. "mkbootdisk" under RedHat or "yast" under
SuSE. Use this repairdisk to boot the defective linux-installation,
check /etc/lilo.conf and call lilo.

And one hint:
It is always a good idea to have a bootdisk on hand...:-)

Solong..
Frank.

Microsoft isn't the answer.
Microsoft is the question, and the answer is NO.

Boot your 2.2.6 disk, and make a boot floppy from that.  Put in the
original disk and boot from the floppy.  Check your lilo.conf and rerun
lilo.

Hi,
Thanks fot the suggestion.
I tried that but it panics. Will I be able to change anything inside the
boot floppy after it has been made with 2.2.6 kernel so that I can boot
2.2.14. 

Warm regs,

Usually the easiest thing to do is boot from any install CD and hit
Ctrl-Alt-F1, which will give you a command prompt.  Then you can mount your
hard disk, edit /etc/lilo.conf and run lilo, something like this:

  mkdir /a                 # a convenient mount point on the CD's ramdisk
  mount /dev/hda? /a       # Change "?" to the number of your root partition
  ls /a                    # you should see bin, usr, etc.
  mcedit /a/etc/lilo.conf  # fix your configuration
  lilo -r /a               # rerun lilo, chrooting to your disk first
                           # take out the CD and reboot

Caveat: I've never tried this myself.  Take a look at the lilo docs to see
some examples of how your lilo.conf should look.

If you need further help you should consider joining an irc channel, for
example, irc.openprojects.net #linpeople

Linux kernel mailing list isn't the right place to ask this kind of
question.
