WHAT IS BOOTING?
Boot is a term used to describe the process of
starting up a computer. Booting can be done
either through hardware (pressing the start
button) or by giving software commands.
Therefore, a boot device is a device that
loads the operating system. Moreover, it
contains the instructions and files which start
the computer.
BASIC STEPS OF BOOTING
1. The Start-up
2. Power On Self Test
3. Loading OS
4. System Configuration
5. Loading System Utilities
6. User Authentication
TYPES OF BOOTING
COLD BOOTING
• A cold boot is also called a
hard boot. It is the process
when we first start the
computer. In other words,
when the computer is started
from its initial state by
pressing the power button it is
called cold boot. The
instructions are read from
the ROM and the operating
system is loaded in the main
memory.
WARM BOOTING
• Warm Boot is also called soft
boot. It refers to when we
restart the computer. Here,
the computer does not start
from the initial state. When
the system gets stuck
sometimes it is required to
restart it while it is ON.
Therefore, in this condition the
warm boot takes place. Restart
button or CTRL+ALT+DELETE
keys are used for warm boot.
