 The booting process is depending  on the three condition
Hardware:- when you start your computer then the first program(OS) is load in the main memory (RAM). if your computer main memory is low. then this process is very slow. if you used ssd and higher ram from your computer then this booting process is very fast. and on your computer within 10-20 second. its depend on your ram and your computer application. so the main part of booting process is hardware.
example:-CPU(control processing unit), RAM ( random access memory), ssd or hard disk,

it is important hardware to help the booting process.

BIOS:- The BIOS ,also known as the basic input output system is a firmware or set of instruction that resides on a ROM chip as contained in the motherboard.

OS:- its full name of operating system (OS). this is the main factor and first software to load in main memory. because without os you do not work on computer. if your os is not full update then booting process is very slow.because if you do not update your os then the new service is not involve in your os.
