I gather this can be very confusing
- hrrrmph! You are not wrong...........
Much appreciate the links. Link1 seems to be related to install, and this problem also happened with XP before I put 7 on.
Link 2 (Dwarf) is closer, but I still have this strange happening that the order is correct on the drive list and wrong on the boot list.
It is a pain having to re-order the boot sequence every now and then, but I can live with it until I find a cure.
