Remove Bootloader on Arduinos I am trying to move from arduinos to AVR C. Would somebody know how to remove the arduino bootloader from the microcontroller? Is there a different process for the different atmega microcontrollers like the 32u4, 328, or 2560?

Thanks.
You don't "remove" the bootloader, you just ignore it.  When you program your new code with the hardware programmer of your choice it will just overwrite the bootloader code with your software's startup code.
