Bios settings - Detailed instructions in pictures. Base code: what is BIOS Where to find BIOS in a Windows 10 laptop

BIOS used in all personal computers for user interaction with hardware, has long outlived its usefulness, and in Windows 10 it was replaced by an updated UEFI interface, which is expandable through firmware additions.

What is UEFI

The next stage of evolution in the development of the BIOS, like the BIOS itself, controls all low-level hardware subroutines, and also performs the main function of its predecessor - initializing the PC hardware components before turning it on and transferring control data to the bootloader found on the drive.

Benefits of the new BIOS with improved GUI:

• Reduced boot time - thanks to the use of thread parallelization technologies during hardware initialization (in BIOS, everything is done in serial mode), the time to check the status of hardware components is significantly reduced.

Interestingly, UEFI contains native drivers for most components, so Windows 10 can use them without forcing the user to download and install drivers on their own.

• Support Windows boot 10 from media larger than 2TB.

To boot the computer into the BIOS, a system of partitions called MBR was used - the master boot record. Having a strictly limited record length of 32 bits, its capabilities were enough to address disk space, which did not exceed 2 TB on one medium. With the advent of UEFI, developers have implemented a new information storage format called GPT. It supports orders of magnitude larger amounts of address space.

• Unlike the BIOS, the new graphics system for realizing user control of the hardware before instructing the bootloader to start Windows 10 has an improved graphical interface. Also, booting into UEFI, you can use the mouse as an input device, which was not in any version of the BIOS.
• UEFI has a set of the most popular applications (their list will be gradually expanded), for example, an Internet browser for navigating sites without using the capabilities of Windows 10.
• Motherboards and laptops that use UEFI support all low-level applications due to the compatibility mode.

UEFI startup

Having considered the main advantages of the new BIOS, it remains to figure out how to enter its menu in order to boot from a USB flash drive (if necessary reinstalling Windows 10), change any settings in the functioning of iron or simply evaluate its graphical capabilities.

You can enter UEFI not only by the classic method by pressing a special key when you turn on the computer, as was the case with the BIOS, but also in several other ways.

• We go to "Start", where we click on the "Settings" icon.

• We go to the tab, which contains the settings responsible for updating the "dozens" and its security.
• We click on the icon labeled "Recovery", then - on the button "Restart now".

• Go to the "Diagnostics" section.

• In the advanced menu options, click on the button shown below.

Next restart Windows 10 will take us straight to the colorful menu of the new BIOS.

If this option seemed too complicated, take the opportunity to get into the BIOS using the classic method. The only thing is that for this you will have to deactivate the "tens" instant download function.

• We go to the control panel applet called "Power Options".
• We click on the link that will lead to the configuration options for the power buttons.

• Uncheck the box next to the "Enable Fast Startup" option.

The article will be devoted to the BIOS on a computer running operating system Windows 10.

For those who don't already know, here's a little useful information, so to speak, in the furnace. If expressed in a simple and understandable language, then the BIOS is special program, which controls the startup of the computer and the loading of the operating system. As soon as the user presses the power button on the computer, bios starts testing the hardware for compliance and performance, checks for the presence of required connected devices ( HDD, RAM memory, video card, etc.).

By entering the BIOS, you can configure all kinds of startup options for the operating system, view system information about the computer and associated equipment, select / change the system boot source (hard drive, CD / DVD drive, flash drive) and much more.

But there is one nuance, which we will discuss further. You can enter the BIOS with certain actions that are different for each manufacturer motherboard. For example, by repeatedly pressing the Del key while turning on the computer, but before the operating system starts loading. There are also options when you need to press the F2, Esc or F1 key.

The BIOS existed before, and still exists today. Let's find out how to get into the BIOS settings on Windows 10.

Computers running operating systems released after Windows 7 (windows 8-10) load the operating system in just a few seconds, during which it is impossible to press the necessary key and enter bios. But this is no longer necessary: ​​you can enter the BIOS in other ways, which we will now consider.

By the way, modern computers are equipped with an improved version of the BIOS, which is called UEFI. Necessary steps to open BIOS on Windows 10:

Alternative way

Another way to enter the BIOS when there is no access to the desktop on Windows 10, but the Logon Screen is open:

Click on the shutdown icon, click Shift key and at the same time select the item, after which a menu of special boot options will open, in which it will be necessary to repeat steps 6-8.

If the operating system does not load at all, then press the power button on the computer and repeatedly press the Del key (or F2, depending on the motherboard).

On any laptop except GUI, which is designed for easy user management, there is also a basic device management menu where deeper system configurations are available. In the BIOS menu, you can access all information about the device, from the model and type of drive to the temperature inside the processor in real time.

Important: Many settings in the BIOS menu significantly affect the operation of the computer, and rashly changing them can adversely affect the productivity and quality of the device. If you need expert advice or repairs, contact a trusted professional service center for Acer laptop repair.

Today we will look at entering the basic BIOS software menu using the example of an Acer laptop with Windows 10.

How to enter BIOS on an Acer laptop with Windows 10

Entering the BIOS on any laptop is very simple, and to do this, you do not need to have special training and additional knowledge.

Launching the BIOS menu on an Acer laptop using the function keys

• Before entering the menu, you must end all active and running processes on the computer and restart it.
• Further, while turning on the computer during the reboot process, before starting the operating system, you need to press the F2 or Del function key, depending on your model. After these steps are completed, you will enter the menu.

As you can see, working with software environment The BIOS is very simple and intuitive, and it also has help on all settings for even more ease of use. But, nevertheless, you still need to be very careful and responsible, since errors in system configurations can lead to serious consequences, up to the arrival of your laptop in a faulty state.

BIOS is a chip on the motherboard of a PC (laptop), which contains a set of microprograms that control the launch and basic settings user equipment, regardless of the operating system. The traditional one has been replaced by a variety of UEFI, their login methods are different, so let's take a closer look at how to enter BIOS on Windows 10.

Entering BIOS UEFI through special boot options

To get started, use one of the four ways to launch download options. Follow the steps below.

shutdown.exe /r /o /t0

Click Enter. This command restarts the PC immediately in desired settings. Without /t 0 in the command, the restart will happen in about a minute with a warning.

After reboot it will appear blue screen, where sequentially go through the sections: "Troubleshooting", "Advanced options". Here you will find the UEFI options, click on them. The final action is clicking on "Restart".

Enable BIOS UEFI via command line

You can start BIOS on Windows 10 using Cmd if you have UEFI. Do the following.

1. on behalf of the admin.
2. Enter the command:

shutdown /r /fw /t 0

1. Click Enter. This command will instantly restart the PC (laptop) and allow you to immediately enter the BIOS. By removing /t 0 from the command, the restart will not happen immediately, but after a minute with a message.

Launching a traditional BIOS through the keys

If earlier to enter the BIOS settings it was necessary to press the necessary key before starting the OS, then in the current realities the concept has changed due to the fast loading of Windows and the presence of UEFI. In conjunction, these two elements will not allow you to get into the BIOS because the user will not have time to press the key due to the quick start, but in this situation the two methods above will help you.

There are bundles of Windows 10 + traditional BIOS, this method works for them. When the computer is turned on, the first thing that happens is BIOS boot, where is the pointer to the key that launches it. It looks like this.

Press YYYY to enter SETUP

Here YYYY is the key that turns on the BIOS. Often it is F2, Del. You need to have time to press this button, otherwise control will be transferred to the OS, and you will have to restart the PC again.

Dozens have a fast boot mode, which makes it difficult to see the BIOS jump key and have time to press it. Before you go into the BIOS, on Windows 10 you need to disable fast boot.

Reboot your PC (laptop), or better, turn it off and on. On the BIOS boot screen, look at the key, and then quickly press it. If you still do not have time to see the keys, then I suggest that you familiarize yourself with these data.

This is far from complete list, if you have not found your equipment, then refer to the documentation of your motherboard, or look for information on the manufacturer's website or forums. Read the article for more information.

On any modern stationary or mobile computer present BIOS system. With the help of this basic system input and output of data interact with each other all the elements of the computer and the operating system. Access to the settings is necessary to increase the performance of devices, in rare cases, to reinstall the system. On Windows 10, the user can access the BIOS in several ways, depending on initial settings systems.

Any model of computer or laptop has a hot key that, when the device is turned on, activates the BIOS. Various manufacturers digital technology set different buttons for this task. There are several ways to find out which key is needed:

• look at the initial black loading screen;
• read the relevant information on the manufacturer's website.

The start screen shows instructions on how to start the BIOS or other important actions.

Problem modern computers lies in very fast loading operating system. Windows 10 users simply don't have enough time to look at . If there is no way to get acquainted with the information from the manufacturer, you can increase the time that the device spends on loading. For this:

After these manipulations, the loading of the operating system will continue enough for the user to see and press the desired key to start the BIOS.

Entering the BIOS from the operating system

Through Windows 10 you will need a pre-installed UEFI mode. This mode present on all operating systems by default. To start the BIOS, you must sequentially perform the following steps:

1. Go to the "Settings" section.

   

2. Open the "Update and security" item.

   

3. Go to the "Recovery" section.
4. In the "Special boot options" field, click the restart button.

   

5. After the reboot, a menu will appear in which you must select the "Diagnostics" item.

   

6. Select the "Advanced Options" tab.

   

7. In the menu that opens, click on the item "UEFI firmware settings" and start rebooting.

   

After the next reboot, the operating system will automatically go into the BIOS. This launch method can be used by users who have access to the OS startup or the start screen where a password is entered.

All of the above manipulations are aimed at unhindered access to the BIOS menu. Using this system, you can configure the interaction between computer components and OS, improve device performance. BIOS menu looks like that.

There is not much difference in entering the BIOS on stationary computers and The difficulty of using the first way to start the BIOS using hot key when turning on or rebooting the device, it only consists in finding the right button. This method suitable in cases of failure of the operating system. The second method is better to use with a working OS.
