    dual-boot knoppix rhe3 (no windoze!)

    I have successfully put knoppix 3.6 on my box, now I want to set up an rhe3 rebuild (centos-3) on the 15gig I left for that purpose. Running the installer is easier enough, but I'm at a loss for booting. Knoppix defaults to lilo; rhe to grub. Have any of y'all out there already done this?

    Here's my thinking...switch from lilo to grub on the knoppix, then I can follow this tutorial: http://www.pcquest.com/content/searc...sp?artid=58131

    All pointers appreciated!

    Go ahead and install rhe (oooh can't beleive I said that ) and put GRUB in the MBR. GRUB is smart and will find your Knoppix install. You can always run update-grub too.

    Yes indeedy, grub sees knoppix. Cool so far. But when I select knoppix I get the following

    Code:
    Booting 'knoppix'
    
    rootnoverify (hd0,0)
    chainloader +1
    
    Error 12: Invalid or unsupported executable format
    So currently no knoppix.

    It's a 40 gig drive; partitions like so:

    hda1-6

    1 100m /boot (knoppix)
    2 19g / (knoppix)
    3 500m swap
    4 extended
    5 100m /boot (rhe)
    6 19g /

    Now I'm thinking it was a mistake to separate out the /boot for each since I'm using grub in the MBR, but, honestly, I'm in the deep-end, competence wise, and if there's a good faq or howto I should be looking at I won't be offended. Googling for info on two versions of linux isn't tremendously fruitful...all the dual-boot docs are about win/lin.

    I wouldn't be mucking about with rh at all if that weren't the target for testing...

    Boot into rhe and use update-grub.

    OR

    I don't use the chainloader but rather specify which partition and kernel I want to boot in /boot/grub/menu.lst like so:

    Code:
    title             Debian
    root            (hd0,1)
    kernel        /boot/vmlinuz-2.6.8.1 root=/dev/hda2 ro 
    savedefault
    boot
    HTH
