Welcome to Dell Tech Support. Want to know more about how the boot process of your computer works? In today’s video we’ll cover this, as well as how to customize the boot process according to your needs. When you turn on the computer, it goes through the following steps. The BIOS loads all the physical components first. Then the POST does a quick check on all of them to make sure each one is okay. And finally the BOOT loads and starts the Operating System, this of course all happens in just a few quick seconds. To customize the BOOT process, turn on your computer and press the F2 key repeatedly to access the BIOS. Go to the BOOT tab and check the options available for customization. The Secure Boot is responsible for protecting your Operating System. When this option is Enabled, your system can only be replaced or partitioned through the restoration process (DELL warranty covers ONLY the original Operating System). Legacy Option ROMs (Read Only Memory) is responsible for the default Legacy BIOS. It’s best to keep this option default as Enabled. But if you do decide to change it, back up your data beforehand as this type of change will be applied to your Operating System. The Boot List Option has 2 options: Legacy and UEFI. This is basically the firmware option you can choose to boot your device. Legacy is the oldest firmware for Operating Systems that will work with the MBR file format (Master Boot Record). UEFI stands for Unified Extensible Firmware Interface which speeds up the boot process but also protects the Operating System. It prevents a new system from being installed over the original factory installation and it is not possible to create other partitions in this mode. UEFI also works with the GGT (GeoGebra Tool) file extension format. Choose the one which best works for your purposes. For additional information on understanding Boot Options within BIOS, check out the link provided in the video description below.
UEFI: Unified Extensible Firmware Interface is a specification that defines a more modernized model for the interface between computer operating systems and platform firmware during the boot process.
MBR: Master Boot Record is a small program that is executed when a computer boots up. Typically, the MBR resides on the first sector of the hard disk.
GGT: a file extension that is related to GeoGebra, a dynamic mathematics & science software for learning and teaching provided by International GeoGebra Institute (a*.ggt file is a user-defined tool file for the toolbar).
