I want to change the bootloader or make a sketch which reads the compiled code from SD card and executes the code as I need to write some huge sketches which will not fit the FLASH memory. I dont have a deep knowledge of bootloader or inners of an SD card and code execution mechanism of Arduino.

That is not possible with arduino. You can execute the binary code which fits in the flash and ram.
