Hello guys, i am trying to use Arduino nano as an ISP to programm bootloader into a MEGA2560 , but i get an error not in sync: resp=0x15avrdude.exe done.

i was succesfully uploaded the same way with an UNO , is there something i am making wrong?
i am using this instructions.. http://arduino.cc/en/Tutorial/ArduinoISP

Try using NickGammon's Arduino as ISP instead.

Sure you can, its just an Uno in a different package arrangement.
D13 is SCLK, D11 is MISO, D10 is MOSI, and D10 is used to control Reset. These pins, along with +5, GND, will connect to the ICSP header, so your cable will just be a little different.

Heck, the Nano already has an ISP header already too:

So all you really need  is some female to female wires and 2 housings to make it all neat:
(connect to D10 on the Nano to the Reset pin on the Mega, the rest are 1 to 1)
