vc deve selecionar, antes de fazer o burn bootloader, o modelo que quer que o bootloader seja gravadado, se vc tem o mega, deve selecionar a placa MEGA e rodar o burn bootloader.
Perdeu o bootloader do Arduino?
Veja o tutorial do nosso colega Flávio Hernan:

o USBASP, pode ter apagado este bootloader.
Regrave o bootloader usando o USBASP e deverá funcionar pela USB para carregar sketch.

the bootloader.
bootloader.atmega8.unlock_bits (default value: 0xFF) is the value to write to the ATmega8 lock byte to unlock the bootloader section.
bootloader.atmega8.high_fuses (default value: 0xca) is the value to write to the high byte of the ATmega8 fuses.
bootloader.atmega8.low_fuses (default value: 0xdf) is the value to write to the low byte of the ATmega8 fuses.
bootloader.atmega8.path (default value: bootloader) is the path (relative to the Arduino application directory) containing the precompiled bootloader.
bootloader.atmega8.file (default value: ATmegaBOOT.hex) is the name of the file containing the precompiled bootloader code (in bootloader.path).
bootloader.atmega8.lock_bits (default value: 0x0F) is the value to write to the ATmega8 lock byte to lock the bootloader section (so it doesn't get accidently overwritten when you upload a sketch).
