How to enter the BIOS without turning off the computer. How to enter BIOS: methods for PCs and all laptops.

Sooner or later, many users have to face the question of whether On Windows 7 or on any other system this can be useful when crashing and reinstalling the operating system when the distribution is on removable media, or when some additional parameters are enabled. Let's look at the main methods. This may be useful later.

general information

Before we begin to consider the question of how to enable BIOS on Windows 7 and make the necessary settings, let’s see what this system is and why it is needed.

If we talk in simple language BIOS is a small device located on the computer, in the memory of which all the basic information about the hardware components and settings of devices installed in the computer system are stored.

In addition, setting up the BIOS (“Windows 7” or any other OS is used) allows you to set completely different system boot sequences, obtain information about the characteristics of the hardware, enable or disable the devices themselves or their additional capabilities, and even overclock the processor.

on Windows 7: standard method

Now let's move on to the main problem. How to enable BIOS on Windows 7? Yes, very simple. Any motherboard manufacturer initially embeds a BIOS chip and assumes the use of special keys to enter.

Surely many owners of, for example, stationary computer terminals have noticed that at the moment of turning on, after the system speaker signal indicating that the BIOS has checked all the “hardware” components, in the middle or bottom of the screen you can see an inscription prompting you to press this and that. then to launch the BIOS.

Most often this is the line Press Del to run Setup (or something else like that). Thus, the question of how to enable BIOS on Windows 7 can be solved by pressing the Del key. However, depending on the manufacturer, this technique may not be effective.

Most often this applies to laptops. Here the situation is somewhat more complicated, since the keys used are different. However, for the most part, the keys used are F2, F12, F1, Esc, less often - F3, or combinations like Ctrl + Del + Esc (or Ins), or Fn + F1. As a rule, laptops are supposed to use several basic combinations, which are indicated on the initial boot screen after the inscription asking you to use a certain press to enter the BIOS. True, this line is displayed on the screen for a very short time, so you should immediately pay attention to it. In principle, if the user has not had time to see which key he needs, he can reboot and at the moment the message appears, press the pause button (Pause/Break key).

on Windows 7 and see basic information

Now a few words about what most users simply do not know. The fact is that any Microsoft operating system has a special system information section. And the “seven” is no exception. This is where you can view data not only about the hardware, the software environment, or the operating system, but also get information about the BIOS. This may often be necessary if you install a more recent BIOS firmware.

You can, of course, enter that section through the start main menu, using administration tools or utility utilities (it all depends on the version of Windows itself), but it is better to use a universal solution - enter the msinfo32 command in the “Run” menu, called + R . On home page in general information and shows basic data.

Interestingly, the system information components are constantly updated, and that is why you can sometimes see that opposite the BIOS operating mode there is an inscription saying that it is outdated. What does it mean? This only means that you need to change the BIOS firmware to a newer one. But doing this without certain knowledge is categorically not recommended.

Instead of an afterword

Here, in fact, is all about how to enable BIOS on Windows 7. When it comes to settings, you need to be extremely careful. However, there are still some recommendations. For example, you need to set the system date and time exclusively in the BIOS, and not in the system, calling the corresponding settings from the system tray. In addition, it is in the BIOS settings that you can enable additional features such as a hypervisor (Virtualization Technology), as well as change the priority of devices in the Boot Sequence so that the first device can use an optical disk or a regular flash drive.

You can generally reset all parameters to factory settings, etc. You can, of course, use the “native” utilities of the motherboard manufacturer, but, as a rule, they do not allow fine-tuning the BIOS. However, we are not talking about this now, since we can talk about the settings of the main and additional parameters for quite a long time.

In simple words.

To enter the BIOS, you need to press a special key when turning on the computer (on the first screen saver) - most often this is F2 or Delete:

Tip: The first boot screen may indicate a key that can be used to launch the BIOS. This inscription is located in the lower right or left corners.

If the operating system splash screen appears on the screen, it means that it was not possible to enter the BIOS. Your computer may have a different key or combination. Here they are full list in order of frequency of occurrence:

Fn+F1
Ctrl+Esc

Ctrl + Alt + Esc
Ctrl+Alt+S
Ctrl + Alt + Ins
Ctrl + Alt + Del

Enter BIOS on a laptop

There is no fundamental difference between a regular computer and a laptop. In order to open the BIOS you need to use the method described above.

For convenience, here is a table of popular laptop manufacturers and the key to enter the BIOS:

*Models with other keys may be available. Use the table as a guide, but if it doesn’t help, try other buttons.

Some laptops do not allow you to enter the BIOS if they are running on battery power. First, connect it to the network.

If the system boots immediately (Windows 10 / 8)

The new version of the input/output system (UEFI) together with Windows 8 and 10 supports instant loading of the operating system - clickable options the desired key no, therefore, you cannot enter the BIOS.

If you encounter this situation, restart Windows while holding down the key Shift.

Instead of rebooting, we will see the “Select action” window - click on Troubleshooting(Windows 10):

Why open BIOS

The basic I/O system has many settings that you can use to control how your computer operates. Here is a list of the most common options that change in the BIOS:

to install the operating system.
Changing the start order hard drive.
Enabling and disabling devices built into the motherboard.
Automatically turns on the computer when power is supplied.

Personal computer, tablet, laptop - many gadgets are used daily by people for work, watching TV series, surfing the Internet and other purposes. From time to time the need arises to reinstall the system, change the PC settings, and the question of how to enter the BIOS in order to make the necessary manipulations becomes relevant. Often there is a hint on the main login page, but such a simple task sometimes causes difficulties, because for different types bios, brands of laptops and systems on the computer you need to press different keys or combinations thereof.

Why you might need to enter BIOS

For many, entering the BIOS is associated with solving one problem - reinstalling, changing the operating system. In fact, with its help it is possible to solve several important issues to improve the functioning of a computer or laptop, find out some data about its operation. Using bios you can perform the following manipulations:

Check the functionality of the computer. It is possible to obtain data about the state of the PC, for example, processor temperature.
Set the system time and date. Performing this action is necessary every time after resetting the BIOS settings, since the date/time configurations change along with them.

}

Connect or disconnect individual functions PC.
Change the disk from which the OS will boot. After opening the BIOS, the user can independently select and designate the location from which the operating system will boot. These can be hard drives, CDs, DVDs or flash drives. You can specify several drive options from which the OS can be started. For example, if for some reason the download does not occur from the first media, it will be carried out from the second.
Connect or disconnect components integrated into the PC. For example, the sound card or video card can be disabled.
Overclock your computer. To improve the operation of the device, increase its performance or speed, or speed up the processor, non-standard frequency and voltage parameters can be set.

Reinstall the operating system, identify and fix problems with its operation.
Check the PC configuration and normal functioning, initialize all its components.
Fix the problem if the Android-based tablet freezes or the gadget does not see connected devices.

BIOS and its main types

Many people have heard about bios more than once, they even roughly understand why it is needed, but what it is, how you can enter the BIOS, what types there are, remains not entirely clear. Before considering questions about logging into the system and the intricacies of working with it, you need to understand the meaning of this word. BIOS is the basic input/output system that is responsible for loading the OS, operating individual components PC, interaction with hardware.

Essentially, BIOS is a large number of microprograms that are recorded on the board. There are types of systems in which the main differences are the interface and login method:

Award (Phoenix-Award). This BIOS has a working area - a blue window.

AMI (American Megatrends).
Phoenix.
DTK (Dalatech Enterprises CO).
UEFI.
ALR (Advanced Logic Research).

How to enter the BIOS of a laptop or computer

To enter the BIOS, you must press a certain button on the keyboard or a combination of them. Which key will help launch bios depends on the type of system and brand of laptop. Often when the PC boots, information about the computer appears on the screen and a hint appears on what to click. As a rule, such a message is located in the middle of the screen or at the bottom and looks like this: “Press Del to enter Setup”; instead of delete, another key or combination may appear. You should press the button immediately after turning on the device.

How to enter the BIOS correctly:

For Award, use the Del (Delete) or Ctr+Alt+Esc key.
For AMI – F2, Delete.
ALR – F2 or Ctr+Alt+Esc.
Phoenix - Ctr+Alt+Esc, Ctr+Alt+S, Ctr+Alt+Ins.
AMD - F1.
DTK – Escape (Esc).

Other button combinations can be used:

Ctrl+Del+Alt
Ins+Ctrl
Ctrl+Alt
Ctrl+Alt+Enter

Login features on laptops of different brands

Depending on the laptop model and brand, the methods for entering the BIOS may vary. Often, a hint is displayed on the splash screen every time the device boots, but sometimes, in order to find the required button or combination, it is worth spending time on “trial and error” or searching for information on the manufacturer’s official website or programmer forums. In addition to the device model, the type of system and its version play an important role.

How to correctly enter the BIOS on different laptops:

Lenovo (Lenovo) - to enter the BIOS, press and hold the “ThikVantage” button until the menu or F12 appears.
Toshiba (Toshiba) Portege, Satellite, Tecra – press Escape, Tecra with Phoenix BIOS – F1.
Acer – F2, F1, Ctr+Alt+Esc.
Acer Aspire – F2, Del.
Asus (Asus) – to enter Setup, press the F2 button.
Sony – F2, F3, F1 for Vaio – F2.
Dell - F3 or F1.
Hewlett-Parkard (HP Pavilion, Tablet) – F1.
Samsung (Samsung) - F2, F12, F8, Del, Esc.
eMachine - Delete.
MSI – F1, F2, F12, Delete.
Compaq - F10.

If the computer requires a password when entering the BIOS

Often a password is placed on the BIOS; it can be set in order to save settings or protect a laptop or all-in-one PC from changes to the system by other users. But memory is a tricky thing, and it often happens that secret code forgotten, but logging in is simply necessary. After several unsuccessful attempts the screen goes blank and the user begins to panic. But everything is not so scary, there are several options for how to enter the BIOS system without a password:

Find a “Clear CMOS” jumper on the motherboard of your laptop or computer, which will clear the memory, including the password. To find the location of the key, you should first read the instructions and the motherboard diagram.
Remove the CMOS battery for at least twelve hours, preferably for a day. Then reconnect it and start the system. The disadvantage of this option is for a long time expectations.
Entering an engineering password for the motherboard instead of the bios code. The disadvantage of this method is that it cannot be used for older BIOS versions.

To avoid such problems in the future:

Set a password to enter the BIOS in exceptional cases.
Write down the password in places where it will be securely stored and, if necessary, can be quickly found.

What to do if you can’t enter the BIOS

Often there are problems when you can't log into the system. This can be caused by several reasons:

The wrong key or combination of keys was selected for entry. Double-check your laptop model and version. It is necessary to try other options and combinations.
The OS boot started before the required key was pressed. It's worth pressing it faster.
To solve some problems, you need to clear the memory, reset it to factory settings using the “Clear CMOS” switch.

Video on how to enter bios on windows 8

Entering the BIOS on a computer with Windows 8 may cause some difficulties. To work, you will need knowledge of the interface and the main features of how the device works with this software. How to enter the BIOS on a G8:

What is BIOS

BIOS (BIOS, Basic input/output system) This is a system that is an intermediate link between the hardware and the computer operating system. The BIOS detects the components connected to the computer, checks them and starts. The user is provided with a special shell with which he can change the BIOS settings.

Essentially, BIOS is special software written onto a special chip located on the motherboard. Also on the motherboard is a battery that powers the memory for storing the date, time and BIOS settings. If you disconnect this battery, all BIOS settings will return to default values.

There is a BIOS for everyone. When you turn on the machine, messages on the black screen before the beep sounds and the OS starts loading are the result of executing one of the procedures of this program. Not very experienced PC users may know about it, but they have never tried to enter the BIOS and have not carried out any manipulations. We'll tell you everything in detail.

What is BIOS

Without software, a computer is just a bunch of hardware. In order for it to start functioning, it must initially be loaded with some kind of software at startup, stored in a read-only memory device (ROM). Windows or any other operating system takes up too much space. Initially, the machine should start the BIOS. The name of this program in the transcription of the English abbreviation “ basic input/output system».

When you turn on the machine, it checks all its components, sets the modes and launches the operating system loader. You cannot simply replace the BIOS version; it is stored in a non-volatile chip on the motherboard. True, it can be reflashed, but this is a rather complicated procedure. Note also that on older machines many operations could be performed even without an OS, for example, listening to music. And Windows itself in the first versions was just an add-on to the BIOS, expanding its capabilities.

Why do you go into the BIOS?

Let's list the reasons why you need to go into the BIOS:

This is not a complete list. By controlling your computer not only from Windows, but also through the BIOS menu, you can increase the efficiency and performance of your computer.

Types of BIOS

Today, three main types of BIOS can be distinguished:

Award;
UEFI.

The first two differ slightly in interface not only among themselves, but also depending on the versions, but the principle of operation in them is almost the same.

UEFI - innovative product, which appeared relatively recently. It has its own graphical interface, is intuitive and allows you to work with the mouse. In addition, with its help the OS loads much faster.

Standard login methods

It makes no difference whether the computer is running Windows 7 or Windows XP, or an older version. By default, most machines mean that you can enter the BIOS by pressing at boot (during the Post diagnostic procedure, before sound signal) F1 or Delete keys. But some motherboard manufacturers assign other keys or combinations thereof; you can find out exactly how to enter in the documentation for it or your computer. If paper instructions are not available, you can always find electronic version, but not always in Russian. Also, during the loading process, a hint is displayed if you have time to read it. Typically it's something like " Press F1 to enter Setup" means you need to press F1.

If you still haven’t found a key or their combination, and the question is how to enter the BIOS, then we will list their main options for the most popular and widespread companies producing PCs and motherboards today. How to enter the BIOS not on a desktop computer, but on a laptop - the procedure is the same, only on some of them the Fn key can be additionally used, which is not present on desktops.

IBM- F1, F2, CTRL + Alt + Insert, CTRL + Alt + Delete.
ACER- F1, F2, CTRL + Alt + ESC.
DELL- F1, F2, F3, Delete, Fn + F1.
HEWLET-PACARD- F1, F2.
SONY- F2, F3.
TOSHIBA- ESC, F1.
ASUS- F2, Delete, CTRL + F2.
LENOVO- F1, F2, F12.
COMPAQ- F10.

Less common brands use the same options to enter the BIOS. As you can see, there are not very many of them and you can easily sort through them.

In order to have time to press a key or a combination of keys when starting the system, almost all users use the following method: they begin to quickly repeat the presses simultaneously with turning on the machine. Sometimes, especially when you need to press a keyboard shortcut, pressing PAUSE helps to pause the boot, but not on all systems. If you don’t have time, then let the OS load, start a reboot and repeat all the operations again. But another difficulty may arise, which will be discussed below.

Even if the correct press does not work

Sometimes you know exactly from the instructions for the motherboard how to open the BIOS, but it doesn’t work. Most likely you have a USB keyboard and it is blocked by another device connected to that port.

There are two ways out:

free all USB connectors and leave only the keyboard;
if there is a connector, connect a regular PS/2 device.

After this you should be in the BIOS.

How to enter BIOS if the system boots very quickly

This issue occurs on modern Windows 8 and later computers that have UEFI, and instead of a regular hard drive there is a solid-state drive. In them, the system boots instantly, and you cannot not only read the hint, but also press a key.

But there is a way out, since in these operating systems you can enter the BIOS when the system is loaded.

Logging into Windows 8

The sequence of actions will be as follows:

Press Win + C. The Win key is most often indicated by the OS logo and wavy windows.
Select " Options", may be designated " Setting"or just a gear.
Find " Change settings».
Select " General».
Then select " Special download option" And Reboot now.
After it, in the window that opens, select “ Diagnostics».
Then find " Additional options».
Stop the selection at "".
Press reboot again.

After completing these steps, you will be taken to the BIOS menu on Windows 8 UEFI.

Sign in from Windows 10

The procedure is almost the same as in the “eight”.

Greetings to all readers of the computer blog site! The other day I came across a Samsung NP300E5C-S0VRU laptop with the BOOTMGR is Missing problem. The problem is basically standard. The solution is to restore the bootloader via Live-CD, or reinstall Windows. Since, according to the client, the hard drive was formatted, they decided to reinstall it.

No problem - everything is as usual, go to the BIOS, set to boot from a flash drive, install Windows. Let's go... Oops... Not so fast, bro!

Samsung NP300E5C laptop does not enter BIOS when pressing f2

The laptop interrupted the process of its revival at the first point. When I pressed F2, it wrote “Entering SETUP” for a split second, but still continued booting from the hard drive, and persistently displayed the message BootMgr is Missing.

Physical disconnecting the hard drive It didn’t give any results - the laptop simply went into a cyclic reboot, not allowing me to either enter the BIOS via F2 or launch Recovery Mode via F4.

Poking around on the Internet showed that the problem is quite common, specifically for this model. The fact is that this laptop has the keyboard locked by default when entering the BIOS. When reinstalling Windows from 8 to 7, you first had to go into UEFI via Win8, disable Secure Boot, and enable CSV. And then carry out some actions to reinstall Windows.

The owner of the laptop somehow formatted the hard drive without first changing the BIOS settings, and, accordingly, received “ vicious circle"- in order to enter the BIOS, you had to install the OS, and in order to install the OS, you had to go into the bios.

BIOS won't start on laptop

Offered on the Internet different solutions this problem, I will offer my own solution, tested by me personally.

List of what you will need:

So, you have a hard drive with the OS installed, you inserted it into your laptop. We launch it, the OS should load. We install pre-downloaded drivers for network adapters, connect the laptop to the Internet via Wi-Fi or cable.

We launch the BIOS update program downloaded from the off. site. This is what the Bios update utility window looks like on Samsung laptops (in the background is the Samsung website, where everything was downloaded from):

As you can see in the picture, the current system BIOS version is the same as the latest bios version available for download (firmware P09RAP). This is because I took the photo after the update.

These versions most likely do not match for you, so, firstly, make sure that you have a battery inserted and charged at least 30%, and a network device is connected. Secondly, click the “Update” button.

So, the progress of the BIOS update has reached its end, the laptop has rebooted. Most likely, the OS will now stop loading, but now this is not a problem for us, because the BIOS is unlocked! We press F2 when loading, change the settings to the ones we need (disable Secure biot and enable Legacy CSV), and calmly install any Windows we want!

Laptop does not enter BIOS - [solved]

It is possible that the problem is when bios does not start when pressing F2, May occur on other laptops besides Samsung. Also, it may occur when replacing a hard drive. Everything is solved by updating the bios to latest version. And updating the BIOS is not such a complicated procedure, as you can see by reading this article!

The most important thing is that there is no sudden power outage, otherwise we will get a “brick”. Which will have to be revived by disassembling the laptop, desoldering the BIOS chip with a hot air gun, flashing it through the programmer, and soldering it back. This is an operation that is not available to everyone.

I'm glad I could help you with my note! If you have any questions, write them in the comments! Don’t forget to subscribe to blog updates so you don’t miss interesting articles on repairing and setting up your computer equipment!

Many users who have laptops or computers, or maybe all together, may encounter problems entering the BIOS. They still clash, so you need to figure out how to enter the Boot Menu. The instructions will not be for one specific computer. I will try to describe as many models of laptops and computers as possible. If you don’t know what a BIOS is, read the article about it here.

Also, if you do not understand this topic at all, then I do not advise you to go there without certain knowledge, since this may entail serious problems. Let's finally get down to business.

In order to enter bios on a desktop computer, usually when you turn it on, you need to press the key DEL (Delete). In general, you should see something like this: Press DEL to run Setup… or Press DEL to Enter Setup... And quickly press DEL.

This entry option is found on motherboards in 90% of cases. It happens that when logging in you need to press either F1, or F2. If you didn’t manage to click in time, you will have to do the procedure again, restart the computer and try to click again. This is quite difficult to do with systems installed on SSD drives. Who doesn't know, read. In general, we talked about computers. Now let's move on to laptops.

From a laptop, logging into Bios is almost no different from the instructions described above for regular PCs, you just need to press different buttons. The only difficulty may be that the device boots up very quickly and you don’t have time to press the right key. On some models, you can press the Pause key to pause the system boot. So, most often, the keys F2, F10, F12 are used to enter the BIOS from a laptop. The most rare case is keyboard shortcuts such as Ctrl+Esc or Ctrl +S, etc.

To enter the same keys are pressed, nothing special.

Now I will describe the BIOS entry for several laptop models.

Acer laptops– you need to hold down the F1, Del or F2 keys

As you can see, I have described quite a lot of options for entering the BIOS from various computers, laptops and motherboards, save these instructions so as not to forget how to enter the BIOS.

BIOS basic input/output system- “basic input-output system”) - part of the system implemented in the form of microprograms software, which is intended to provide the operating system with an API for accessing computer hardware and devices connected to it

When you turn on the computer's power, during initial boot, using programs written in the BIOS, a self-test of the computer hardware occurs - POST ( power-on self-test). During POST, the BIOS checks the functionality of the controllers on the motherboard, sets low-level parameters for their operation (for example, bus frequency and parameters of the central microprocessor, controller RAM, bus controllers FSB, AGP, PCI, USB)

During POST, a prompt appears at the bottom of the screen: Press DEL to run Setup, - DEl (Delete) is the most common key to enter BIOS Setup

Entering the BIOS allows the user to configure various settings: enable or disable devices or available ports, set the boot priority of devices or their sequence. Some advanced settings also allow the user to adjust the computer's performance, such as CPU clock multiplier and system bus (FSB) frequency for overclocking, DRAM memory settings, for flashing new BIOS versions, etc.

Keyboard shortcuts

To enter the BIOS, the user must press a specific key or key combination during the initial BIOS boot screen. Below is a list of PC OEMs and the key or key combinations to enter the BIOS. Please note that some manufacturers may have multiple methods for accessing the BIOS depending on when the BIOS was released.

Computer manufacturer	Keys
Acer(Aspire, Power, Veriton, Extensa, Ferrari, TravelMate, Altos)	Del or F1
Acer(Altos 600 Server)	Ctrl+Alt+Esc or F1
