Boot process ka basic outline kuch is tarah hota hai:

  1. Power On: Computer ko start karne par, power supply on hoti hai.
  2. Power-on Self-Test (POST): Computer ke hardware components, jaise ki RAM, processor, hard drive, etc., ko test kiya jata hai. Agar koi issue hota hai toh POST error generate hota hai.
  3. Bootstrap Loader: Jab POST complete hota hai, toh computer ek small program ko execute karta hai jo “bootstrap loader” ke naam se jana jata hai. Ye small program computer ke storage device (jaise ki hard drive) se aur bhi bade program ko load karta hai.
  4. Master Boot Record (MBR) or EFI System Partition (ESP): Yeh step depend karta hai ki aapka computer BIOS (Basic Input/Output System) ya UEFI (Unified Extensible Firmware Interface) use karta hai. MBR ya EFI System Partition se operating system ka bootloader load hota hai.
  5. Operating System Load: Finally, operating system ka kernel load hota hai aur computer user interface par pahunch jata hai.

Boot process mein koi bhi problem ho toh computer proper tarike se start nahi hota. Isliye, jab kabhi aapka computer sahi se boot nahi ho raha ho, toh aapko hardware ya software issues ko resolve karne ki jarurat hoti hai.
