Burning the boot loader in an atmega328 could be somewhat tricky but if u follow these steps correctly youll be able to bootload any type of atmega328 micro controller ..
Step 1: “setting up the hardware”
– An Arduino board (any type)
– 18-22pf capacitors (x2)
– 16 MHZ oscilator
– Breadboard
– 10 Kohm resistor
– Jumper wires
– ATMEGA328-PU or ATMEGA328P-PU
– Bread board
.
.
Assemble everything as shown in the figure (on a bread board) :
– arduino board (pin10)->breadboard (pin1)
– arduino board (pin11)->breadboard (pin17)
– arduino board (pin12)->breadboard (pin18)
– arduino board (pin13)->breadboard (pin19)
– (pin 7 ) and (pin20) of breadboard ->+5v of arduino board
– (pin8) and (|pin 22) of breadboard ->gnd of arduino board
– 10 Kohm resistor from(pin 1 ) to +5V
-16 MHZ oscilator from (pin 9 ) to (pin 10)
– 18-22pf caps : first one from (pin 9) to gnd ,second one from pin 10 to gnd

Now for the hard part made easy .
.
.The software.
