First a few things should be checked - maybe something went wrong at OF-startup.....

Go to Open Firmware and type printenv and post the output here (Photo).
Next type devalias and post it here too.

Post the layout of your HD here with the device-names (not the disk-names, which normaly appears on Ambient-desktop).

The next step after that will be listening content of boot-partition (MAC-HFS-partition) and try to boot MorphOS-kernel manualy (if it is there).
