Unable to bootload arduino uno using Arduino mega2560 as isp

Using Arduino Microcontrollers
#1

Hi,

everyone from last few days i am trying to program my arduino Uno atmega328p using Arduino Mega 2560, but failed to do so. I have used the exactly same steps which i have used to bootload arduino uno through another arduino uno but this time with no luck.

I am getting the following error :

avrdude: device signature = 0xff00ff;

avrdude: Expected device signature for Atmega328P is 1E 95 0F

I double checked the wirings and still with no luck.
