Boot

In computing, to boot a system is to turn the device or machine on and load the operating system into random access memory. The boot-up process is made up out of different stages, depending on the setup of the system and the operating system that has to be loaded. For most cases, these stages are important parts of them:

  • The BIOS or UEFI are powered up and do the Power-On Self Test (POST)
  • The bootloader loads the operating system
  • Once all the operating systems files have been loaded, control is given to the OS.
