Earlier I was unable to see the Arduino Mega 2560 Dual bootloader option in the Arduino 1.8.2 IDE
I copied it to My documents Arduino and copied the bootloader text inside the folder as per error.
Now it shows..
The current selected board needs the core 'arduino:arduino' that is not installed.
help to resolve
Thanks
