Hello everyone and welcome to this
video.
So we have seen the Linux boot
process. Similarly. Let's quickly understand
the overview and generic version
of Windows boot process of how
a Windows operating system starts.
So similar to the Linux operating system
here, we can see that there is bios.
There is also a bootloader.
There is boot files.
Kernel and instead of the init and
the Run levels we can see starting services
and checking Sam by
LSA. So let's quickly understand. What are
these new things?
So the first one is bios, which
functions exactly the same which is the basic
input output system, which execute the
bootloader.
The second one is the bootloader which checks for
the ntldr files if
they are available or no?
The next one is the boot files which checks
the important required boot
files like boot.ini, which is
responsible for successfully booting the system.
The next is the kernel which is responsible for
the kernel execution of the
operating system, which is also known as the heart
of the system.
The next is the services. So unlike Linux
Windows works on
services. So it checks all the
required initial services and starts
all the services required by the operating
system to function.
And the last one is the screen which is
presented in front of you where you
log in with your username and password, which is the
checking Sam by LSA.
Here Sam stands for the security account manager
and LSA is
your local security Authority.
Now remember whenever you log in into a computer
your passwords are never saved into plain
text in terms of Windows whenever you
log in your passwords are hashed and
saved into a secure location by
the Sam.
In terms of Linux your passwords
are again hashed and saved into a
secured location, which is only being
checked when you login into the
system.
So I hope you guys understood the Windows boot process
and how it functions. Thank you.
