    Booting Knoppix from hdd using grub problem

    I was working with redhat fine. then i installed knoppix to a different partition. now i can not boot knoppix from hdd nor the redhat. i get the following errors.

    1 )for redhat :

    ( installed on /dev/hda6 )

    the kernel line works fine
    the initrd line initrd /boot/initrd-2.4.20-8.img

    error : 15 file not found.

    however when i get to rescue mode from cd, the file is there. how come the grub doesn't find it.

    2 ) for knoppix :

    it is installed on dva7

    error 17 : can not mount selected partition

    root (hd0,7)
    filesystem type unknown partition type (0x82)

    when i check from booting the cd i do fdisk -l
    it gives hda7 as ext3 ( 0x83 ) not as ( 0x82), also when I boot from the cd I can access hda7. how come the grub does not recognize my partition ?

    I do not know if this question fits here but is there terminal based partition program from redhat or knoppix or both ? (qtparted is not included in my knoppix distro )

    dva7? I presume you meant /dev/hda7 and if so your grub entry is wrong. remember, grub starts counting from 0 not 1.

    Code:
    root (hd0,7)
    is /dev/hda8

    when i check from booting the cd i do fdisk -l
    it gives hda7 as ext3 ( 0x83 ) not as ( 0x82),
    Well I'm guessing that /dev/hda8 is your swap! You should do man update-grub
