    Hi there, I seem to be having the same problems as tudor, Iam trying to install knoppix 5.3.1 on my computer hardrive and it uses the knoppix-installer v0.3.19.19, how ever just as tudor said, after I installed Knoppix on the HDD, I was told to make a boot floppy, and I selected “No” to the “boot floppy needed” option, after which came the cloop errors. then i press enter and it say knoppix installed successfully………….however when I tried to boot the system up from the harddrive, i get the following mwessage ——GRUB LOADER ERROR 2. what does this all mean? someone please help.

    I still have the same problem with Knoppix 5.1.1 boot CD, no matter of whether swap partition is on or off, and no matter of using default mode or expert mode, run level 2 or run level 5.

    Basically, if my CD/DVD drive stops spinning, the commands which have already been run, they run ok, but if you try other commands, it has to read from the CD, it gives cloop errors.

    So, I try to do everything before my CD drive stops spinning, and then I have no problem with Knoppix. I really have to be fast in doing that.

    As I said, that Knoppix CD and the present Knoppix CD verifies completely ok, so it has no burn errors on it.

    If CD and Drive both are fine try at boot: prompt
    knoppix testcd

    Also try to pass nodma option. Some CD drives are not compatible with Linux DMA implementation.

    I think I got it:

    swap partitions have to be turned off before any partitioning programs and have to be turned off before starting knoppix-installer.

    So, this is how I did it:

    $ su
    # swapon -s
    # umount /dev/….
    # swapon -s
    # exit
    $ sudo knoppix-installer

    I still got the following errors with knoppix-installer v0.3.19.19:

    Can’t open /mnt/hdinstall/home/tgeorgescu/.mozilla/default/*/prefs.js: No such file or directory.
    Can’t open /mnt/hdinstall/sbin/hotplug-knoppix: No such file or directory.
    grep: /usr/share/applnk/./Internet/NX Client for Linux: No such file or directory

    I want to add something: it happened after I installed Knoppix on the HD, and it offered me the possibility to make a boot floppy, and I answered “No” (no boot floppy needed). After that, there came the cloop errors.

    I have burnt Knoppix 5.1 CD twice, both verify ok (one with self-test, the other is a md5-verified burn of the Knoppix CD 5.1) and both give me cloop errors, after a time of waiting for input.

    More precisely, I started knoppix-installer from the text console (either with init 2 or with Ctrl-F2) and after it installed it said it cannot read some of its module files, giving me cloop errors. I had the same problem with knoppix-installer in a KDE environment.

    Both CD’s are properly burnt, they are clean, and the drive is ok. So, besides unmounting something or going inactive, I have no other explanation for Knoppix’ behavior.

    What do you think I have to do in order to avoid such cloop errors? Do I have to press some keys every 30 seconds or so, to keep the Knoppix thinking I am doing something?
