As it turns out, there isn’t much to the boot process:
1. A boot loader finds the kernel image on the disk, loads
it into memory, and
starts it.
2. The kernel initializes the devices and its drivers.
3. The kernel mounts the root filesystem.
4. The kernel starts a program called init.
5. init sets the rest of the processes in motion.
6. The last processes that init starts as part of the boot
sequence allow you to
log in.

Booting Process:
1) BIOS: BIOS is the lowest level interface between computer
and peripherals.
The BIOS performs integrity checks on memory and
seek instructions on the Master Boot Record (MBR) on the
floppy/HDD.
2) The MBR points to the boot loader (GRUB or LILO: Linux
Boot Loader)
3) Boot loader (GRUB or LILO) will then ask for the OS label
which will identify which kernel to run and where it is
located (Hard drive and partitioned)
4) The first thing the kernel does is to execute init
program. init is the root/parent process to all processes in
the Linux.
5) The first processes that init starts is a script
/etc/rc.d/rc.sysinit
6) Based on the appropriate run-level, scripts are executed
to start the various processes to run the system and make
it functional.
