Development Tools Uploading

I have two nanos, one has bootloader and the other doesn't. When i try to burn his bootloader i get this error:

avrdude done.  Thank you.

Failed chip erase: uploading error: exit status 1

On "Tools > Programmer" i selected "Arduino as ISP"
On "Tools > Processor" I've already tried both ATmega328P

You need a programmer to burn a bootloader; are you using a programmer or trying to burn the bootloader via USB? You can use your working Nano as a programmer; do a search for Arduino-as-ISP.

I forgot to say this, but i'm using my working nano as a programmer

The very first record is weird. Expected 0x14, received 0x14 and error! The sequence 0x14, 0x02, 0x 10 in the response is correct.

Check your wiring, just to be sure as it looks more like something with SW.
Try to upload ISP sketch again and check your preferences in setting carefully.
