How to Enter the BIOS on Any Windows and PC

Posted on

How to Enter the BIOS?, You have made various efforts to restore the assertiveness of the performance of a laptop computer or desktop PC. Starting from deleting unnecessary files, uninstalling unused programs, to defragmenting the hard drive or registry. Apparently, viruses are the main culprit behind your computer.

Then, it occurred to you to install antivirus software. It’s just that antivirus is not able to handle it. The final solution is to reinstall Windows. Incidentally, your computer doesn’t have a DVD Room. Therefore, reinstalling can be done by copying the Windows installation file to a flash disk and then converting it to bootable.

To be able to manually reinstall Windows with a bootable flash disk, you have to enter the BIOS to make minor adjustments. That setting is to make the flash disk the first priority when the laptop boots. Well, for those of you who don’t know how to enter the BIOS, Weblogue will share the steps.

These steps will apply to different brands of laptops and desktop PCs, so don’t worry. However, before going there, first, see what BIOS is and what its functions are.

Overview of the BIOS

If there is no BIOS, a computer will not function. This is because the BIOS plays a role in initializing all the devices installed on the motherboard. This includes loading an existing operating system on a hard disk, SSD, or diskette in ancient times (DOS).

The late Gary Kildall was the figure behind the creation of the BIOS. The man who died in 1994 initially created an operating system to control and monitor microcontroller devices (1975). However, Kildall thought that his own operating system could also be used for more complex devices such as computers.

Initially, Kildall’s innovation could only run one command because it runs on 8 bits. Over time, the BIOS can handle a variety of tasks because it is designed with large bits. IBM, which was attracted by Kildall’s invention, implemented it in practice starting 1981.

Since then, all IBM computers have been injected with this technology, which stands for Basic Input / Output System. Several companies such as American Megatrends and Phoenix Technology modified IBM’s BIOS to match the specifications of the computers they were running.

Functions and How the BIOS Works

When there is a device that goes wrong, the BIOS will provide information in the form of voice or writing, so that the user can check it. For example, there may be a broken cable, RAM is not plugged in properly, or the processor fan does not turn on. In this case, the BIOS also plays a role in holding the computer from entering the operating system.

If all devices connected to the motherboard are OK, the BIOS will execute the MBR (Master Boot Record). The MBR, which is located in the first sector of the hard disk, is responsible for loading the operating system and running it. In addition to being able to perform checking functions, the BIOS stores time information, processor temperature, passwords, and so on.

In advanced use, the BIOS provides access to adjust the voltage and frequency of the motherboard and all other attached devices. This activity is commonly called overclocking which is useful for increasing computer speed. The BIOS is stored on a special chip that integrates with the motherboard.

Its rewritable nature allows the BIOS to be updated without having to replace the chip. Simply install the update from the computer. If on an Android phone, this BIOS is similar to recovery software such as TWRP or CWM.

How to Enter the BIOS on Windows 10 (And Older Versions)

Every brand of laptop or desktop PC usually has a different BIOS. This of course makes the access methods are not the same. In fact, one laptop brand with a different type or series is sometimes not the same way of access. However, basically, the access steps are the same. Only the access key differentiates between one computer and another.

Well, Weblogue will provide just one example of how to access the BIOS of a Dell Latitude E6420 laptop. The operating system used on the test laptop this time is Windows 10. Here are the steps:

  • First of all, press the restart button from the Windows start-up window. You can also press the power button when the laptop is turned off. Wait for a moment.

  • As soon as the laptop displays the Dell logo, press the F2 key quickly.

Apart from F2, the key you can press is F12. The F12 key here functions to set the priority order of the drive (hard disk, DVD Room, or flash drive) when the computer boots.

For laptops or other brands of computers, the steps are the same, namely by taking step number one. However, when stepping on step number two, the access keys that are pressed vary.

Especially for some types of Toshiba laptops, how to access the BIOS is done by pressing and holding the F2 key while the laptop is turned off, followed by pressing the power button. Here Weblogue presents a variety of BIOS access keys from various brands of laptops.

The steps for entering BIOS on a desktop PC are basically the same as for a laptop. However, one brand and another brand may have the same access key. It depends on which BIOS vendor is used or what motherboard is used. Following are the BIOS access keys based on the BIOS vendor and motherboard brand:

UEFI

If the methods described above do not work, then it could be that the computer you are using is not using BIOS, but UEFI. Some laptop manufacturers have started to switch to UEFI configuration systems since 2010. For your information, UEFI stands for Unified Extensible Firmware Interface.

California processor manufacturer Intel has stated that 2020 is the last year it will support its BIOS. They will then move completely to the more modern UEFI. Before discussing how to log into UEFI, you may ask why BIOS was abandoned, and what are the benefits of using UEFI? You can find the answer to that question at the exclamation point below.

Why UEFI?

Intel is the initiator of the first of the system previously named this EFI. However, 140 companies around the world formed a forum to jointly develop it. Companies that are incorporated include AMD, ARM, American Megatrends, Microsoft, Lenovo, and HP.

The group of companies believes that UEFI is the answer to speeding up the boot process as well as modernizing the old-school BIOS appearance. Various limitations that exist in the BIOS were resolved with UEFI.

For example, UEFI no longer needs a boot sector (in this case MBR) when loading the operating system. This makes it boot faster than BIOS. Likewise, with the time it takes when the computer is turned on from hibernate state.

The partition capacity of a bootable drive is also large, more than 2 TB. Then, because it supports 64-bit device drivers, UEFI can accommodate 17.2 billion GB when the computer starts up. The UEFI interface is also more intuitive with a number of features that manufacturers can customize.

The UEFI operation is much more flexible as it can be done with a keyboard and mouse. Computers or laptops from 2010 and below generally support UEFI. However, manufacturers usually still include BIOS built into UEFI.

How to Login UEFI

Microsoft fully supports UEFI since launching Windows 8 in 2012. They also provide easy access to UEFI via Recovery mode. Follow these steps to UEFI for those of you using Windows 8, 8.1, and 10.

  • Click Start then go to Settings.
  • Slide the initial Settings view to the bottom row. Then select the last menu, namely Update & Security.
  • Then, click the Recovery menu which is in the order of six of the Update & Security tab.
  • Look to the right and hover over the Advanced startup section. Click the Restart now button.
  • Wait a few moments until a new look appears. Then, go to the Troubleshoot menu.
  • Then, enter the Advanced options menu.
  • Select UEFI Firmware Settings.
  • Click Restart and wait for the UEFI display to appear.

This is a brief explanation of BIOS, UEFI, and How to Enter the BIOS on Any Windows and PC. If you look closely, all BIOS access keys are placed on the first array of the keyboard. Starting from Esc to Del, regardless of computer brand.

This fact makes you not need to look for BIOS access keys other than those on the first row of the keyboard. So, if you don’t have a clue and don’t know the exact key, just try pressing Esc to Del. However, if you still can’t find it, immediately enter recovery mode, it’s possible that your desktop PC or laptop is already using UEFI.
