Can I install a GFCI receptacle in a kitchen and a bathroom that does not have a ground wire? The wiring is just 2 wires.

Yes you can. GFCI receptacles sense a current difference between the neutral and hot lines. If there is a difference, current is going somewhere it shouldn't and the GFCI will trip.

A GCFI receptacle should come with a warning sticker to apply to receptacles installed without a ground wire.

If your receptacle happens to be installed in a grounded outlet box, then you can get a ground from the box.
