What is the first step of the boot process?

Answer 1

I believe this is how your computer boots:

1.) Your computer looks for and executes the BIOS. (Basic Input Output System)

2.) The BIOS boots your computer further by searching for drives that have a bootloader (first sector) at least 512 bytes long.

3.) The BIOS then runs the first 512 bytes.

4.) The Bootloader then runs the kernel.

5.) The kernel now runs more kernels. One for the screen, one for the mouse, one for the keyboard, one for the speakers etc.

6.) Those kernels import DLL files.

7.) With "teamwork", the kernels do everything else that the authors of the operating system programmed them to do when the OS was created.

8.) The operating system takes it from this point.

I am not sure about the REAL way it boots. I am just assuming. So, if you ask me, I would say the computer executes the BIOS.
