I am very confused but this does not work. I took a different machine running 10.04 trinity. It has only a root partion with jfs on it. So when I boot with my virtual 10.04 Cd and then try to mount via mount -t jfs /dev/sda5 /tmp2 Or what ever mount complains: "wrong fs type or bad superblock": the usual message of mount when something is wrong. I have also on /dev/sda1 a windows partion with ntfs. This one I can mount. So I am stuck. There must be something very elementary which I miss, but what? Thanks Uwe Brauer
