I know that you can use an Arduino to reprogram an AVR uC, but can you program the bootloader with an Arduino, or do you still need something like the AVR programmer? If its possible, how is it done?
If you setup arduino as isp (arduinoisp)
You can burn bootloader yes.
Oh. Is there a tutorial for how to do that?
Try the Arduino forum.

Ive already done that. They say that this works for Arduino-type AVRs (e.g. the ATmega168 or ATmega328 used in Arduino). But would this work for an ATMEGA32u4 or even an ATTINY45?
