    How to install second Knoppix to play with? - Solved !

    Hi,

    unfortunatelly while installing a second knoppix (hda9) to play with, I overwrote the mbr.

    So cannot start the original knoppix installation (hda6), as it is not listed in lilo anymore.

    But I still do have the original lilo.conf file in mnt/hda6/etc/lilo.conf.

    How to make the original knoppix installation on hda6 bootable again?

    Listed:
    1) cfdisk
    2) original lilo.conf
    3) new lilo.conf

    Any help very appreciated,
    JanMartin

    / cfdisk looks like this:

    Just add these lines to the lilo.conf file of your bootable hda9:

    other=/dev/hda6
    label="knoppix(hda6)"

    Save changes then run Lilo. Reboot. Knoppix on hda6 should be listed when the Lilo boot option screen comes up. Choose it and you will boot into hda6.

    Thanks,
    did so, then run lilo, but it does not work:

    jan@testboxhda9:~$ su root
    Password:
    root@testboxhda9:/home/jan# lilo
    Added Linux *
    Added Windows(hda1)
    Added Windows(hda5)
    Fatal: First sector of /dev/hda6 doesn't have a valid boot signature
    root@testboxhda9:/home/jan#

    So how to make a valid boot signature from the original lilo.conf file and how to install it into hda6 partiton?

    Boot from the Knoppix CD and open a console window then:
    Code:
    sudo mount /dev/hda6 /mnt/hda6
    sudo chroot /mnt/hda6 /sbin/lilo -b /dev/hda6
    The second command will chroot (change the root) to the hda6 and then run lilo telling it to install itself to the partition for the install which is hda6. This should fix the error you get above so you can install the lilo with the changes and boot both. When you have used the hda6 option from the lilo that is installed to the MBR you will see a second lilo that is now installed into the / partition that is the hda6 install that you will have to use to boot that install.

    How to install second Knoppix to play with? - Solved !

    Thanks P2C2E,
    thanks Stephen,

    its working.
    Actualy I am writing this in my old beloved hda6-system.
    There was no need tore boot from CD, just uisng the hda9 system.

    This is what I did:
    jan@testboxhda9:~$ su root
    Password:
    root@testboxhda9:/home/jan# mount /dev/hda6 /mnt/hda6
    root@testboxhda9:/home/jan# chroot /mnt/hda6 /sbin/lilo -b /dev/hda6
    Ignoring entry 'boot'
    Warning: '/proc/partitions' does not exist, disk scan bypassed
    Added Linux *
    Added LinuxOLD
    after that
    root@testboxhda9:/home/jan# lilo
    Added Linux *
    Skipping /vmlinuz.old
    Added Windows(hda1)
    Added Windows(hda5)
    Added Linux(hda3)
    Added Knoppix(hda6) <- Jiiiiipeeeeeeee !
    root@testboxhda9:/home/jan#

    Indeed, now there are two lilos to run to boot hda6.
    I am thinking about how to make the second one to run without interaction needed?

    Thanks,
    JanMartin

    Did it!
    Now the lilo.conf in hda6 does not show the red splash screen anymore, and runs immediately without any keystrokes needed.
