Detailed explanation-1: -In computing, booting is the process of starting a computer as initiated via hardware such as a button or by a software command. 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.
Detailed explanation-2: -Go to Start, select the Power button, and then select Restart.
Detailed explanation-3: -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"). Your computer knows how to boot because instructions for booting are built into one of its chips, the BIOS (or Basic Input/Output System) chip.
Detailed explanation-4: -The CPU starts and fetches instructions into RAM from the BIOS, which is stored in the ROM. The BIOS starts the monitor and keyboard, and does some basic checks to make sure the computer is working properly. For example, it will look for the RAM. The BIOS then starts the boot sequence.
