Booting is basically the process of starting the computer. When the CPU is first switched on it has nothing inside the Memory. In order to start the Computer, load the Operating System into the Main Memory and then Computer is ready to take commands from the User. Learn the types of booting.

What happens in the Process of Booting?
Booting happens when you start the computer. This happens when we turned ON the power or the computer restarts. The system BIOS (Basic Input/Output System) makes the peripheral devices active. Further, it requires that the boot device loads the operating system into the main memory.
Boot Devices
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. Examples are the hard drive, floppy disk drive, CD drive, etc. Among them, the hard drive is the most used one.
Types of Booting
There are two 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.
Steps of Booting
We can describe the boot process in six steps:
1. The Startup
It is the first step that involves switching the power ON. It supplies electricity to the main components like BIOS and processor.
2. BIOS: Power On Self Test
It is an initial test performed by the BIOS. Further, this test performs an initial check on the input/output devices, computer’s main memory, disk drives, etc. Moreover, if any error occurs, the system produces a beep sound.
3. Loading of OS
In this step, the operating system is loaded into the main memory. The operating system starts working and executes all the initial files and instructions.
4. System Configuration
In this step, the drivers are loaded into the main memory. Drivers are programs that help in the functioning of the peripheral devices.
5. Loading System Utilities
System utilities are basic functioning programs, for example, volume control, antivirus, etc. In this step, system utilities are loaded into the memory.
6. User Authentication
If any password has been set up in the computer system, the system checks for user authentication. Once the user enters the login Id and password correctly the system finally starts.
Frequently Asked Questions (FAQs)
Q1. What is booting?
A1. The starting up of the computer is known as booting. It initiates all the devices before starting any work on the computer. Moreover, the operating system is loaded into the main memory.
Q2. What is BIOS?
A2. BIOS stands for Basic Input/Output System. It helps in the functioning of all the input/output devices. Further, it also helps to start and initiate the working of all devices during the boot process.
Q3. What are the boot devices?
A3. Boot devices are the devices that have the operating system loaded inside them during the boot process. Common devices are the hard drive, disk drive, floppy drive, etc.
Q4. What are the types of booting?
A4. There are two types of the boot:
Cold Boot/Hard Boot
Warm Boot/Soft Boot
Q5. Why do we need booting?
A5. We perform this so that the operating system along with the initial files and instructions load into the main memory. And as a result, the computer starts.

Locate your computer's power button. If you want to boot a tower PC (Monitor connected to a boxlike device), then the button is most likely to be on the boxlike device (tower). If you are using a laptop computer then the boot button is most likely to be on the inner side of the laptop, usually on one of the upper corners.

Power on your computer. After locating your computer's power button, press it to power on your computer. Your PC will now boot into the BIOS (Basic Input Output System) part. This is the part of the boot process that tells your computer what it should do. E.G, boot windows, give a keyboard error, turn off the PC for overheating, etc. Without this system, you computer would be soulless and useless.

Wait for the operating system to load. Depending on the speed of your computer, the operating system could take a while to load. Normally, no input would be required here, unless your computer failed to boot, then you will need to select some from some recovery options.
