    OK, the main task is to save files from the computer. Maybe after that you can try something else, particularly if you have an external monitor, for example test how it works with an installed linux system.

    -o-

    The picture you uploaded indicated that /dev/sdb1 is already mounted to directory /cdrom, and it is on your USB boot drive.

    Try these commands (and post the output). The first one is 'ell ess space minus ell space slash'

    Code:
     ls -l /
    Code:
    ls -l /cdrom
    Code:
    df -h
    The output will tell us if you can use /cdrom. (I think so, but I am confused because you cannot find it.)

    The directory is there and there are 11 GB free (for your files to be saved). But I cannot see if it is read/write, because the line for /cdrom was outside the screendump of the second picture.

    Anyway. Open a new window of file browser and change directory to the 'computer' or 'root directory' '/' (slash). There you should find alongside for example /mnt also /cdrom. Change directory to /cdrom and then you have one browser window at /mnt and one browser window at /cdrom. Now you can drag and drop files (or even directories, but beware, the limit is around 11 GB).

    And it will be slow, very slow, because USB drives are slow compared to an internal HDD. Do not unplug the pendrive until it has finished, maybe several minutes after you think it has finished.

    If you have a terminal window open, you can run the command
    Code:
    sync
    and when it returns to prompt, the files have been written to the pendrive.

    Please make a new attempt to show the permissions of the /cdrom directory:

    ell ess space minus lower-case-ell upper-case-ell space slash space pipeline grep cdrom

    Code:
    ls -lL / | grep cdrom
    and again (if something might have changed)

    Code:
    cat /etc/mtab

    I think the problem is that root owns /cdrom and has exclusive write access. We might be able to change that:

    Code:
    sudo chmod -R go+w /cdrom
    Otherwise you need to copy with root (superuser) privileges, which is also possible. But let us try this first.
