    When they said who wants a warped sense of humor, I thought they said who wants a good sense of humor... and I raised my hand!

    The following Terminal command should list AppleJack if it is installed:

     

    sudo ls /private/var/root/Library/Scripts

    As a further check you can use the following Terminal command:

     

    sudo cat /var/root/.profile

     

    This should result in:

     

    alias applejack='/var/root/Library/Scripts/applejack.sh'     #AppleJack Installer

    echo ""     #AppleJack Installer

    echo "For troubleshooting assistance, just type 'applejack' at the prompt"     #AppleJack Installer

    You could try the following in single user mode:

     

    sh /var/root/Library/Scripts/applejack.sh

    I've got the int HD partitioned and running Xu/Lu 12.0.4, the crash problem started there and that's not new, but then continued over into the OSX side.

     

    I am still of the view that this could be the cause of your difficulties.

     

    It is unlikely that the partitions interfere with each other but there are other areas which are common such as firmware - on such an old Mac this may not be strictly firmware but battery backed RAM.

     

    Some OSs use hidden disk partitions but I doubt that this is an issue here.

     

    It is perplexing that booting into single user mode does not invoke /var/root/.profile - I have never met this.

     

    Duel boot is OK as long as it works but it is difficult to know where to start when it goes wrong.

    Years ago tools like Norton helped in mapping out bad parts of disks but life has moved on and now they are likely to do more harm than good.

     

    Firmware on modern disks should map these out without any user involvement.

     

    At one time I did overcome a bad scratch to a disk caused by my foolishly using a fixing screw which was too long. After much playing I was able to split it into 3 partitions - OK 1, scratch and OK 2.

     

    I do not know why single user mode does not automatically run /var/root/.profile on your Tiger but  does on my Leopard. Perhaps those at the following could explain this:

    Please keep in mind that I changed the topic of conversation from the iMac, to asking about the AJ installation on my MacBookPro running 10.6.8

     

    Sorry - missed that unexpected switch - distracted by the outbreak of humor perhaps!

     

    Whilst under normal circumstances I would advise taking it to the Snow Leopard forum I am aware that the Technology forum is followed by several people who could probably easily answer such questions.
