[debian-knoppix] SOLUTION: Dual booting knoppix/win2k from HD without floppy/cdrom and without touching W2K MBR.
I would like to publicaly thank you Christian Perle.
The folowing solution he gave me work like a charm.
All the command work without problem.

The command on the next line just amaze me, I use to do this in 5 commands.

I had already an ext2 partition that I use for putting my development tools.
So I just had to reuse it and add a few file in it.
However I did try exacly what you said and it is working.

> cp -a /dev/hd[a-h]* /mnt/test/dev
The above command was not working for me so I used
cp -a /dev/hda /dev/hda? /mnt/test/dev
> cp -a /boot/*.b /home/vmlinuz /home/miniroot.gz /mnt/test/boot
I am not sure if it change anything, but one file was a link to another
file.
So I choose to unlink and make a real copy.

I was a bit lazy so I made
cp /etc/lilo.conf /mnt/test/etc
Then I edited the file to match what I wanted.

I did replace the above by copying to the vfat partition that host the
knoppix/knoppix file.
I just had to remount the partition to have rw access:
mount /dev/hda3 /cdrom -o remount
But the floppy solution is maybe easyer and safer.

IT WORK... and there is little risk since you do not touch the MBR.
Here are the things I complain about ;-)
1) Every time you upgrade to a new version of knoppix (and the floppy
change)
you have to redo the "lilo -r /mnt/test", copy the 512byte block, ...
And you need to make sure your ext partion is not mounted in "nodev".
2) You have to write your own kernel argument in lilo.conf,
so if you want the same behaviour as the official knoppix floppy image,
you will have to copy those parameter manualy.
3) The upgrade procedure require a few reboot.
I am still going to investigate a solution based on dualbooting Win2k and
DOS.
Then from within the DOS partition boot linux (loadlin or other).
This would permit to "upgrade" my knoppix from within win2k without to many
reboot.
Also GURP seems to be a good potential solution too.
I need to investigate.
"upgrade" knoppix mean:
Downloading a new knoppix.iso file.
Extracting the boot.img and other file from the iso using isobuster (or
other)
Extracting the miniroot.gz and vmlinuz by rawriting boot.img to a floppy.
(or maybe using winimage)
Reinstall whatever dual/boot you found to be working.
