What is this exe? Generally, you'd need some sort of OS to execute that exe.

suppose I have made a program using c or c++ and created its executable file, I want to run that .exe file during booting (not after the operating sytem gets loaded on RAM) using any bootable device. Is this possible?

Unless you create your own tiny OS, or some code that actually interacts with the hardware, no.
The OS is what talks to the hardware.

Back in the mid 90's, it was quite common for a game to boot and run from its own floppy or CD.
But that basically included its own DOS bootloader.

What are you actually trying to create and do?
