You will load the bootloader first. The bootloader is so that you can load the FW using USB. Without the bootloader your computer USB doesn't recognize that there is a chip attached. You can also load the FW using the ISP so it's really your choice.
I have programmed the PIC successfully and my computer detects the Megadrum. Now I want to know If I can directly burn the firmware to the ATMEGA using the USBASP programmer without the bootloader?
