how to open bios setting

► Let’s start with the discussion about how to open bios setting? Guide to opening the BIOS setting in Desktop/ Laptop Step by Step help with pictures and also basic of bios, legacy, UEFI. It’s very easy to open bios setting and change the boot options or more changes.

► First of I’m clear your few questions about of bios. What are bios?

→ Bios is basic input/output system. It manages data flow between the computer’s operating system, hardware control and attached devices such as the keyboard, mouse, DVD drive, hard disk, video adapter and printer etc. without bios your os is not booting up. BIOS is much outdated. BIOS was the first popular firmware for desktop/laptop PC introduced in 1975 by IBM. In short manage of your os and hardware.

► What is Boot up?

→ Boot is an alternate name of boot up or booting. The boot is used to load an operating system into computer/machine’s random access memory (RAM) and start up your operating system. Boot support Legacy mode and UEFI boot mode.

► What is Legacy bios mode?

→ Legacy Boot is the boot process used by BIOS firmware. The legacy bios are outdated bios mode. Enumerates them in a configurable order of priority. Legacy uses the Master Boot Record (MBR) scheme. Legacy mode supports up to 2TB (Terabytes) partition size.

► What is UEFI mode?

→ The Unified Extensible Firmware Interface(UEFI). The UEFI is the successor to BIOS. Alternate name EFI. UEFI uses the GUID Partition Table (GPT) scheme. UEFI is supported up to 9ZB (ZetaBytes) partition size. GPT and MBR are both formats specifying physical partitioning information on the hard disk.

►  It is recommended to install any operating system in UEFI mode.
Note: One cannot install in UEFI mode by booting in legacy mode. and can’t install in legacy mode by booting in UEFI mode.

► The difference between UEFI and Legacy mode-

✞ Maximum partition size in MBR is up to 2TB whereas in UEFI it is up to 9ZB.

✞ MBR can have at max 4 primary partition whereas GPT can have 128 partitions.

✞ MBR can store only one bootloader whereas GPT has a separate dedicated EFI System Partition(ESP) for storing multiple bootloaders.

✞ This is very helpful if you have two or more operating systems which require different bootloaders.

✞ UEFI offers secure boot which can prevent boot-time viruses from loading.
