I would like to build a special board for a specific project using the ATmega2560 similar to the arduino mega 2560 board but not using all the components of it.

I need to know how to proceed with the loading of the arduino bootloader. Anyone can help me with some guidelines?

First you have to have a programmer. You could also use an Arduino as one: http://arduino.cc/en/Tutorial/ArduinoISP.
Then just open the Arduino IDE and click on Tools -> Board and select Arduino Mega 2560. Then click Tools -> Burn Bootloader and select your programmer. After 30 secs or so you should get a reply in the bottom bar, stating that you either were sucessful or the bootloading failed.

How to wire it up:

... and connect this according to the pin names on the programmer.
