The BIOS start the monitor and keyboard. The BIOS then starts the boot sequence. It looks for the operating system stored on your hard drive and loads it into the RAM. The BIOS then transfers control to the operating system, and with that, your computer has now completed the startup sequence.

Why does a normal hard boot take longer than a normal soft boot? Correct. In a hard boot, the BIOS/UEFI must perform the initial steps before loading the OS. Pressing F8 when Windows 10 is loading will launch the Advanced Boot Options screen if it has been enabled.

The boot process begins when you push the power button, which sends power to the bootloader in the cache memory. The bootloader program performs a POST, or Power On Self Test called, and if everything is okay, the Basic Input Output System, or BIOS, is activated and then finds and loads the operating system.

Booting (also known as booting up) is the initial set of operations that a computer system performs when electrical power is switched on. The process begins when a computer that has been turned off is re-energized, and ends when the computer is ready to perform its normal operations.

Booting is what happens when a computer starts. When you boot a computer, your processor looks for instructions in system ROM (the BIOS) and executes them. They normally ‘wake up’ peripheral equipment and search for the boot device. The boot device either loads the operating system or gets it from someplace else.

In computing, booting is the process of starting a computer. After it is switched on, a computer’s central processing unit (CPU) has no software in its main memory, so some process must load software into memory before it can be executed.

An operating system has three main functions: (1) manage the computer’s resources, such as the central processing unit, memory, disk drives, and printers, (2) establish a user interface, and (3) execute and provide services for applications software.
