The process of bringing up the operating system is called booting (originally this was bootstrapping and alluded to the process of pulling yourself up “by your bootstraps”).

What is the difference between warm boot and cold boot?
A cold boot generally does nothing but completely resets the hardware and reloads the operating system. Warm boot, on the other hand, refers to the boot process in which a system regains its initial state without hampering the power source.
What is the POST process?
Overview of the Power On Self-Test (POST) Process
When the computer is first turned on, all the components must be tested and initialized by the BIOS, and the operating system must be loaded into memory. This is commonly referred to as POST (Power-On Self-Test).
What happens in POST and no POST?
No Post Issues. The term POST refers to Power-On Self-Test, which is a series of checks the computer goes through whenever it starts. If the computer fails any of these tests, it stops the start-up process and report a fault.
What is the purpose of BIOS in a system?
BIOS (basic input/output system) is the program a computer’s microprocessor uses to start the computer system after it is powered on. It also manages data flow between the computer’s operating system (OS) and attached devices, such as the hard disk, video adapter, keyboard, mouse and printer.
