Booting in Windows Safe Mode

Booting in Windows Safe Mode

In computer terminology, booting is the process that a computer performs after it has been plugged in to an electrical outlet and pressed on the CPU’s power button. All the processes that a computer undergoes from the time the CPU has been started and up to the time when the operating system has finished loading all necessary programs, all of these activities compose booting.

You cannot define booting pointing only to one particular task. It is composed of many different tasks that are automatically done by the computer. Among the tasks included in booting are:

POST or Power-on Self-Test – this is the very first thing a computer does right after you press on the power button of the CPU. This test verifies and initializes all chips in the motherboard, the memory card, video card, network adapter, sound card, optical drive, hard drive, monitor, power supply, processor, all cooling fans, keyboard, mouse, and all devices attached to the CPU.

Loading of the operating system – once the POST is finished and no error was detected, the actual loading of the operating system begins. This is when Microsoft Windows, Mac OS X, or Linux starts to boot. In this process, the drivers of all installed devices will be initialized and started. It loads and starts the program that handles the keyboard, mouse, monitor, motherboard chipset, hard drive, optical drive, network adapter, video card, and more.

It also loads and starts the programs that are set to run along with the operating system. These are the programs included in the Startup group. The operating system also starts and stops different services for different functions and also adds stability.
