wilykat:
It says you are using stk500v1 as the programmer. Change Programmer option to "Arduino as ISP" in the board menu since you are trying to use Uno. Change board (not programmer) to Uno first, upload Arduino ISP sketch from File menu, then change board to Nano for burning and make sure you have the wires to nano correct and Programmer set to Arduino as ISP
Thank you Wilykat,
I can upload the bootloader to another Uno board. (connect Uno board to Uno board). I change Uno board to nano with the same wiring but it doesn't work. I can't upload bootloader to nano board.
