    Boot from Knoppix ISO in HDD using grub

    I used the following code:
    Code:
    menuentry "Knoppix ISO" {
    insmod part_msdos
    insmod ext3
    set root=(hd0,msdos2) #the partition where you've stored knoppix iso
    loopback loop /KNOPPIX_V7.0.4DVD-2012-08-20-EN/KNOPPIX_V7.0.4DVD-2012-08-20-EN.iso
    linux (loop)/boot/isolinux/linux boot=isolinux iso-scan/filename=/KNOPPIX noeject noprompt --
    initrd (loop)/boot/isolinux/minirt.gz
    }
    everything works, then knoppix iteratively searchs KNOPPIX in /dev/sdax for a few times and lets go.
    Where I am going wrong?

    I have uploaded the relavant files in my google drive. You could click the file and peruse them. Any doubt that remain will, I hope, be cleared by the pics.
    The logical drives that I have are given, also the drive in which the knoppix iso resides is apparent from the codes in the main post. The files could be accessed at:

    Code:
    loopback loop /KNOPPIX_V7.0.4DVD-2012-08-20-EN/KNOPPIX_V7.0.4DVD-2012-08-20-EN.iso
    This isn't a sufficient path-declaration.

    Thank you, Prof. Schulz.
    I studied and experimented with the information retrieved from the link you'd provided, & I solved the problem.
    The relevant code contained in the link, even when customised to suit a particular system such as mine, is not correct. I found that the following code works beautifully, and the checkpoints confirm it:
    }
    echo 1
    menuentry "Knoppix ISO" {
    echo 2
    set root=(hd0,msdos2) #the partition where I've stored knoppix iso
    echo 3
    loopback loop /KNOPPIX/KNOPPIX.iso
    echo 4
    linux (loop)/boot/isolinux/linux64 bootfrom=/dev/sdb2/KNOPPIX/KNOPPIX.iso boot=isolinux keyboard=us
    initrd (loop)/boot/isolinux/minirt.gz
    }
    I hope this helps others. I write in the Debian forum as bkpsusmitaa

    I'm not a "Prof.". In Germany it is a title only for teachers at university.

    You aren't a Professor!? Not only in Germany, I think the world over "Prof." is a title for tenured teachers in Universities. I thought that your knowledge-base as a moderator of the forum should ensure your being a Professor of a Univ.
    I am sorry for my assumption. But my respect and awe remain, nonetheless!

    The above menu entry was for my desktop, which had an AMD processor. Otherwise, the menu entry could be: ############################################## menuentry "Knoppix_8.2 ISO" { echo 1 set root=(hd0,msdosx) # x=partition number where the iso resides echo 2 loopback loop /KNOPPIX/KNOPPIX_V8.2-2018-05-10-EN.iso echo 3 linux (loop)/boot/isolinux/linux bootfrom=/dev/sdax/KNOPPIX/KNOPPIX_V8.2-2018-05-10-EN.iso keyboard=us root=/dev/ram rw ramdisk_size=100000 lang=us apm=power-off echo 4 initrd (loop)/boot/isolinux/minirt.gz } ############################################## Hope this helps ...
