Further Install Help Needed

[tilleyrw]

Booting from the Knoppix 3.8.1 CD and supplying the boot-string "acpi=off screen=1280x1024 depth=24", the basic Knoppix desktop appears on my screen.

After remounting / as rw, editing /etc/lilo.conf to point /dev/hda1 and saving, the problems begin!

root@1[knoppix]# mount -n -o remount,rw /
root@1[knoppix]# df

Something is either wrong with remount / (root) as read-write or my /etc/lilo.conf file. How can I open the lilo.conf file which was installed on /hda1? This new virtual filesystem is difficult to learn. Any and all help is most appreciated!

Here's Mister Ed's handy-dandy 8-step procedure for fixing LILO after booting from CD or another partition - he's had to do it many times! :wink:

[1] If you're only booting from CD (or whatever) just to fix LILO, use the cheatcode that puts you in run level 2 (the command line) - that saves you a little frustration while waiting for the GUI to load - so at the CD prompt you'd type knoppix 2.

[2] When you mount hda1 you have to include the option -o dev.

[3] Now use the change-root command to be in the hda1 environment: # chroot /mnt/hda1.

[4] Edit /etc/lilo.conf - just like that, not /mnt/hda1/etc/lilo.conf - and you'll be working on hda1's lilo.conf rather than the one that the CD loaded into RAM.

[5] If you have other bootable Linux partitions, you mount them within the chroot environment, not before - so you can make this step [4] and do editing as step [5], but the other bootable partitions have to be mounted after step [3] and before step [6].

[6] Now run lilo to write the changes to the boot sector.

[7] Leave the chroot environment with # exit or # <CTRL>D.

[8] Reboot with your favorite command, # reboot or # init 6 or # shutdown -r now.

Okay? :D
