Burning bootloader not happening

Hi, i am fairly new to this but is not the first time I burn a bootloader using this setup, but for some reason is not working anymore, I am using an UNO board and a USBtinyISP to burn a blank chip, and I get the following message (Arduino 1.0.5):

avrdude: Device signature = 0x1e9307
avrdude: Expected signature for ATMEGA328P is 1E 95 0F
Double check chip, or use -F to override this check.

Can some one please help me solve this?

Cheers

what chip are you trying to burn it onto ?

May be you should check your hardware , and you can try to use "CMD " .
1.find the "avrdeude" Path,and open the "CMD";
2. enter instruction,like this "c:/......./ avrdude -p at90usb8u2 -F -P usb -c usbtiny -U flash:w:************(your bootloader path) -U lfuse:w:0xff:m -U hfluse:w:0xd8:m -U efuse:w:0xfd:m -U lock:w:0x0f:m "then enter "Enter" in your key board
ps:the value like "lfuse,hfuse,efuse" will be find in the txt file (c:/..../arduino/hardware/avr/boards)
