Another thing to do, if you have Norton's NU, is to go
into "Explore disk", "Choose item" and "Absolute sector",
then you press RETURN four times, and you will get the "PARTITION TABLE"
on screen, here you can see, whether this disk is bootable or not.

Make the one you wish to boot from bootable, and the other one
non-bootable.

But be CAREFUL when doing this, do NOT change anything else.


            Hope this helps.
