I've downloaded the MikroC pro for pic compiler 5.61, and I have a ICD2 Programmer , I want to use the bootloader Capability to load my code the problem is :
1- Where can I find the .hex file for 18f4550 48Mhz ?
2- is it possible to use serial bootloader , How ?
3- if not how can i use the Usb bootloader ?

Not sure if I understand this correctly, you want to transfer the actual program from one chip to another blank one? or are we talking data transfer here. You obviously need software running on both chips to transfer data. If it is just data, then really any coms protocol should be ok. It is possible to copy a program if you had the data file held

You are talking about using a serial bootloader, the only problem is that you need a proper Pic programmer to program the bootloader in to the Pic to start with.
If you Google on ' Pic serial bootloader' you will find entires from Microchip AN1310 and Tiny how to do the whole procedure.

Cannot answer your question as such, that bootloader code and App note seems quiet complicated.
What I would ask you, is why are you, as a beginner, trying to use a complicated bootloader ?
You have to use a programming device like a Pickit2 or 3 to ' burn in' the bootloader code to your target chip.
So if you have a (...)

this makes me more confuse about WHY THEY MADE bootloader although its so near to serial programming ??:?::?::?:
Because a serial programmer needs external hardware and a software program control. A boodloader once loaded needs nothing, except a terminal program which is available in any operating system.

Compare the datasheets of the two microcontrollers, maybe you missed something.
You can't communicate via serial port? In what way? The bootloader or you created a program to access the serial port?

Yes, once you burn a bootloader into your micro, you can then just program the part using the serial port. Myself, I just use the ICD2, and find it just about as convenient, in most cases, as a bootloader. I hope this answers your question.

Can i ask as to why do you want to use a bootloader of that particaular baud rate?
If you want to use the serial port later in your code then it is not necessay for the baud rate of the bootloader to be the same as that of the baud rate that you want to use in your own code.

A bootloader in general is a small program used to download the main program into the micro's memory. This allows you to change the program of the micro without using a programmer.
Note that the micro must be capable of writing to its own FLASH, otherwise this will not work.
You do not always require a bootloader, only when it is necessary for

a bootloader is a small piece of firmware on the PIC which can communicate with external devices (usually a PC via serial COM or USB) and 'upload' the rest of the program on to the PIC flash memory.
