MegaCore makes it very easy:

You only need to:

  • Install MegaCore following the instructions at the link above.
  • Tools > Board > ATmega2560
  • Tools > Clock > "8 MHz internal" or "1 MHz internal"
  • Connect an ISP programmer to your ATmega2560. If you don't own a dedicated ISP programmer, you can use a spare Arduino board as an "Arduino as ISP".
  • Tools > Programmer > select the appropriate programmer
  • Tools > Burn Bootloader
