Simplifying Boot Process

When the computer is switched on, a small computer programme runs a basic test on all the essential hardware to ensure that it is functions properly.
Afterwards, it wakes up the motherboard and hard disk and calls the system files of the operating system as it is the part of the boot procedure. The operating system will then take over from the boot file and load all the required system files and driver software for the hardware. After all the required files are loaded through this process then the operating system is ready to use.
