If any part of burning the bootloader succeeded when Uno was the selected board then any further attempts at serial programming will require an external clock (crystal+caps, resonator, or clock signal on XTAL1). I have no idea if high-voltage parallel programming will require an external clock. I suggest getting an external clock connected before continuing. If nothing else doing that will eliminate it as the problem.
I have a variation of the ArduinoISP sketch that provides a suitable clock signal. If you'd like a copy send me a Personal Message.
