Hello, I have a question regarding the installation of a bootloader using two arduinos.

  1. Does the arduino used as programmer need to have a preinstalled bootloader?
    Yes, as there has to be a way to upload the arduinoISP sketch into the board so it will become a programmer board.

for the reasons of this questions I agree, but I want to go circular, as I have a non bootloaded 168 that I loaded the ISP sketch onto using an ISP programmer, that I now use as a stand alone programmer ... point still stands you need a way to get the ISP sketch on the chip before you can use it, easiest is to use a bootloaded chip

Circular indeed. You kind sir are a knight of the nerds, of the first order. :smiley:
