Open the ArduinoISP firmware (in Examples) to your Arduino board.
Select the items in the Tools > Board and Serial Port menus that correspond to the board you are using as the programmer (not the board being programmed).
Upload the ArduinoISP sketch.
Wire your Arduino boards..
Select the item in the Tools > Board menu that corresponds to the board on which you want to burn the bootloader (not the board that you're using as the programmer). See the board descriptions on the environment page for details.
Select the Arduino as ISP in the Tools>Programmer menu.
Use the Tools/Burn Bootloader command.
You should get this as part of the output message from the Uno used as Arduino as ISP.
avrdude: AVR device initialized and ready to accept instructions
