I. Introduction
BIOS, short for Basic Input/Output System, is a firmware embedded on the computer’s motherboard that initializes and tests hardware components during the boot process. BIOS also contains settings and configuration options that control how the computer hardware interacts with the operating system and other peripherals.
Accessing BIOS is crucial for troubleshooting hardware issues, reconfiguring system settings, updating firmware, or installing the operating system. This article will provide a comprehensive guide on how to enter BIOS on popular computer brands.

VI. Troubleshooting Guide
If you encounter the following problems when accessing BIOS, here are some possible solutions:
Password recovery: Some BIOS systems require a password for accessing the setup utility. If you forgot the password, try removing the CMOS battery from the motherboard or using a BIOS password recovery tool.
Hardware failure: If some hardware components fail during the boot process, they could prevent accessing the BIOS. Try disconnecting all peripherals or removing one component at a time until you identify the faulty one.
Incorrect settings: Mixing incompatible BIOS settings or trying to overclock the computer could lead to fatal errors, such as the Blue Screen of Death or the computer not booting at all. Always double-check the instructions before making any changes to the BIOS.
VII. Comparison between Systems
Traditionally, BIOS used to be the primary firmware used to initialize and test the computer’s hardware. However, newer computer systems are now using the UEFI (Unified Extensible Firmware Interface) BIOS instead, which offers several advantages over the traditional BIOS.
UEFI BIOS supports larger hard drives, faster boot times, and better security features than the traditional BIOS. It also provides a more user-friendly interface and enables the computer to boot from non-traditional devices, such as network adapters or flash drives.
The method of entering BIOS can differ depending on whether you have a traditional BIOS or a UEFI BIOS. However, most computer brands have adopted the same key combinations to enter BIOS regardless of which BIOS type you have.
