3.0 Operating Systems and Software


3.4 Explain the basics of boot sequences, methods and startup utilities

  • Disk boot order / device priority

    • Types of boot devices (disk, network, USB, other)

  • Boot options

    • Safe mode

      Safe mode is a diagnostic mode of a computer operating system, using only default settings (VGA monitor, Microsoft mouse driver, no network connections, and the minimum device drivers required to start Windows). If a symptom does not reappear when you start in safe mode, you can eliminate the default settings and minimum device drivers as possible causes. Windows automatically initiates Safe Mode if it detects a system boot failure or registry corruption. Safe mode can be accessed manually by pressing the F8 key as the operating system boots.


    • Boot to restore point

    • Recovery options

      • Automated System Recovery (ASR)

      • Emergency Repair Disk (ERD)
