In this article, we will explore the process of setting up and configuring the BIOS on a Dell Inspiron Notebook in a Windows environment. The BIOS (Basic Input/Output System) is a firmware that is responsible for initializing hardware components and booting the operating system. It is crucial to understand and adjust BIOS settings to optimize system performance, enable/disable specific features, and troubleshoot issues.

Examples:

1. Accessing BIOS: To access the BIOS on a Dell Inspiron Notebook, follow these steps:

   • Start or restart the notebook.
   • As the Dell logo appears, press the F2 key repeatedly until the BIOS setup screen appears.

2. Adjusting Boot Order: The boot order determines the sequence in which the system searches for bootable devices. To change the boot order in BIOS:

   • Access the BIOS as mentioned in the previous example.
   • Navigate to the "Boot" tab using the arrow keys.
   • Use the "+" or "-" keys to rearrange the boot devices.
   • Save the changes and exit the BIOS.

3. Enabling/Disabling Secure Boot: Secure Boot is a feature that ensures only trusted software can run during the boot process. To enable or disable Secure Boot in BIOS:

   • Access the BIOS.
   • Go to the "Security" tab.
   • Locate the "Secure Boot" option and use the "+" or "-" keys to enable or disable it.
   • Save the changes and exit the BIOS.
