Geekers - The boot process is carried out by the computer systematically according to the procedure. After you press the power button, electricity will be distributed to all computer components via the power supply. Then, the CPU will run the BIOS or UEFI whose job is to ensure that any installed hardware is ready for use. If nothing goes wrong, BIOS or UEFI will look for the bootloader in the Master Boot Record (MBR).
On Windows, the bootloader is called Bootmgr.exe. On Mac, the bootloader is called boot.efi. As for Linux, it's called GNU GRUB or GRUB. The bootloader itself is sometimes written separately as a boot loader.
Next, the bootloader switches the boot task to the Windows OS Loader (winload.exe) which will activate the Windows kernel until finally the Windows login window appears on the monitor screen.

In the computer world, the process of turning on a computer that starts from pressing the power button until the operating system is ready to use is called bootstrap, startup, start-up, boot, boot up, or boot.
That's why the process of restarting the computer is also known as rebooting. However, if the computer is in hibernate or sleep mode when it is turned on, then this process is not referred to as booting or rebooting. Booting and rebooting itself can only be applied to bootable devices such as hard disks, SSDs, CD/DVDs, and flash drives.
The boot process occurs in seconds or minutes which speed depends on many factors. For example, the type of media used for booting, whether it's HDD, SDD or CD/DVD. The fastest is SSD but the price is more expensive than HDD. Several other factors that also affect boot speed are the amount of active software at startup, viruses, system configuration, RAM capacity, and the amount of hardware installed.
The final word…
There are a number of ways you can apply to speed up booting. It starts with removing hardware that is not or is rarely used so that the hardware drivers are not loaded every time the computer boots. Then also make sure that the system is not infected by any malware, and don't forget to reduce the timeout when booting.
Also reduce the number of software and services that automatically run at boot time. One service that you can disable is Windows Search. Instead, use David Carpenter's or Listary's Everything software. Both are free and are faster, lighter and have more features than Windows Search.
