I bought a nano and tried in every to load something even using a mega to exchange the bootloaderi with isp but it dosen't work: avrdude: stk500_recv(): programmer is not responding avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0xc8 avrdude: stk500_recv(): programmer is not respondin…

Also take a look at the chip on the underside of the Nano. That's the USB-to- Serial converter chip and you will need the correct driver for that chip.
