How to enter BIOS on a Lenovo laptop. How to enter and configure the BIOS of a laptop LENOVO G500, G505 to install WINDOWS from a USB flash drive or disk

Entering BIOS for system administrators is a common procedure. Most users do not delve into the intricacies of setting up a computer or laptop, do not try to reinstall Windows on their own or use booting from a USB flash drive or CD / DVD, and generally have little idea about BIOS. For them, entering the settings of the basic I / O system is not at all necessary. Moreover - not having an idea of what and where you can configure in BIOS- you can "mess things up": in the best case, the computer simply will not boot, and in the worst case, you can irreparably damage the hardware. Usually the central processor suffers due to its (over-) overclocking and overheating ... However, if you are theoretically savvy, but have difficulty with by the entrance to the BIOS, we recommend that you familiarize yourself with the most popular ways to open its settings.

The most popular method.

Go to BIOS on desktop computers familiar to all (desktop / stationary computers) it is usually quite simple - for them, for a long time, the button “ Del". In more modern models of motherboards, there is an option using the " F2". In most cases, when you turn on the computer, on the very first screen with information about the hardware, there is a hint like “ Press Del key to enter Setup Menu". Instead of " Del"A different value may be specified, but this is rather an exception. By the way, the screenshot contains a hint about how to enter the boot menu. It is to select the device from which you want to boot (usually USB Flash or CD / DVD drive) most and try enter BIOS.

Depending on the settings / configuration of the computer, this screen may appear from a split second to several seconds. To open BIOS settings you should press the button indicated in your case (until the download proceeded further). Usually they do this - when the computer is turned on, the desired key is pressed at intervals of a little less than a second. before the appearance BIOS menu ... Its modern modifications may have different looks, but ... I think you will recognize it. The screenshots show user interface motherboard "MSI Z77A-G43" and the menu for the virtual VMware machines... In the first case, we see a modern version in graphic mode with mouse support and blackjack, and in the second - an ascetic "text" menu. Note that even the VMware virtual machine has a choice of boot device.

Go to BIOS on a laptop.

I can't say why, but manufacturers don't give it so easily go to BIOS on a laptop in modern models. It so happens that when turned on, none of the " F1 ... F12»Do not allow you to open the desired settings. Recently, owners of Lenovo Notebooks of various models have come to me more often. For several modifications Lenovo G500 laptops enter BIOS succeeded by pressing the key combination " Fn + F2"After switching on (" Fn + F12"- boot menu). As it turned out, this is a fairly simple way. For Lenovo B590, everything turned out to be a little different ...

When I got in my hands laptop Lenovo B590 go to BIOS did not help either " F1 ... F12", No key combination" Fn»+« F1 ... F12". Everything turned out to be quite simple - there is another one next to the power button. additional key ... This is exactly what you need to press when off laptop... When you turn on this button, you get to service menu, which will allow you not only to get into the settings discussed in the article, but also to perform a number of other service operations.

Laptop manufacturer Lenovo G590 prudently added several language localizations for this " engineering regime". Among others, there are English and Russian languages. To go to BIOS would need 6 (six!) mouse clicks: select the Russian language, specify the Russian keyboard layout, enter the "Diagnostics" menu, open the "Additional parameters", select " UEFI Firmware Options", Click" Restart ". This is how the process evolved from one button " Del"To the chain with the most illogical (for me) item" Diagnostics ". After Lenovo G590 laptop will be loaded again - it will appear in front of you BIOS menu.

The site already has a number of articles that mention or imply a change in the boot device. For example, an article about or. Both articles describe the operations that are performed after booting from a USB flash drive... It is to install a boot from a USB flash drive that many want to get into BIOS settings, although this is not at all necessary due to the presence of a separate Boot Menu to choose Boot Device.

BIOS is very important computer program written on the chip of the motherboard. It allows the user to change the settings of the software and system software, making them low-level, provides assistance in repairs, and acts as a regulator in the operation of the motherboard. The first thing the wizard does when a computer or laptop breaks down is to enter the BIOS. In 80% of a hundred, it is from there that he receives information about the causes of a system malfunction.

Common ways to sign in on a Lenovo laptop

The most common and well-known way to enter the BIOS is by pressing the Delete key on the keyboard. However, some computer and laptop manufacturers, including Lenovo, have defined other login methods for their systems.

When choosing Lenovo when buying a manufacturer, you must remember that the computer equipment of this company is produced, as a rule, with an already installed operating system. If you want to reinstall the software on your laptop, you may face a problem: almost all modern models ignore the operating system you want, trying to return the computer to the original one. For this, you will need the ability to log into BIOS on your own in order to get around this problem.

Booting a Lenovo laptop from a USB flash drive via BIOS

Most often, this operation is performed by specialists in order to cure a laptop from viruses. Various software is written to removable media, but it is usually not so easy to boot from it. The problem is that all the latest Lenovo laptop models, starting from the 2013 release, have UEFI BIOS software that has Secure Boot certified security keys. It is they who allow you to boot a laptop only when using a licensed installation disk Windows 8.

In order to boot from the media in such a BIOS, you must disable Secure Boot in it by following these steps:

After all the steps taken, the laptop will start the next boot from the USB flash drive.

Please note that for some Lenovo models, disabling just one Secure Boot setting may not be sufficient. You may need to enable Compatibility Mode to boot the system from removable media.

In various models, it can be referred to as CSM OS, CSM Boot, Legacy BIOS, UEFI and Legacy OS, or simply CSM.

They inform the user about the configuration of the laptop, show the main specifications of this model, make it possible to download and configure the security system. On the screen, all these sections are displayed as "", " Configuration», « Boot», «», « Exit».

Pay attention to an important detail. When moving to the BIOS, the mouse connected to the laptop stops working, therefore, being in the software menu, navigation is carried out using the buttons with pointers. It must be remembered that in all configurations, without exception, the changed settings begin to work only after they are saved and the laptop is rebooted.

Connect your Lenovo laptop to AC power. If power is suddenly cut off during BIOS operations, this may adversely affect the continued operation of the computer.

If you do not have instructions for a Lenovo laptop at hand, you will have to go online and find out the necessary information on the manufacturer's website (http://www.ibm.com/ru/ru/). This can be done both online and by downloading the instructions in the form of a detailed PDF file... In order to read this manual, the computer must be installed special program, for example, Adobe Reader (http://www.adobe.com/ru/) or Foxit PDF Reader (http://www.foxitsoftware.com/).

If, for technical reasons, access to the Internet is not possible, then you will have to act independently. Turn on the computer and watch the information appear on its screen. Usually, to make life easier for the user, at the very beginning of the laptop, for a couple of seconds (just while the BIOS conducts a test poll of computer devices) a hint appears in the form of a key name or a key combination that must be pressed and not released until then, until the laptop enters the BIOS table.

Pay attention to the designations F2 and F12. It is these keys on a Lenovo laptop that are designed to interrupt the test polling of devices and prevent booting. operating system.

Press and hold the F12 key on your keyboard. Thus, you indicate your desire to enter one of the BIOS partitions, which is called Quick Boot. This small but very important subset of the computer architecture is designed to prioritize the boot of the computer. Going into the priority table, you can change the order in such a way that after successful work BIOS computer first I acted, for example, to the CD-rom, then to the USB-port and only then to the HDD. Such operations with the boot line are typical for the reinstallation of the operating system on a Lenovo laptop.

Press F2 to enter the main BIOS menu. Here advanced user accesses the settings of a large number of parameters various devices... Unlike conventional PCs, Laptop BIOS also allows:

Set up a security system;
- change the nature of the touchpad;
- correct the output of the image on the display;
- calibrate the battery, and also see serial number device, its motherboard and other equipment.

BIOS is basic software that allows you to interact with your computer without accessing a disk. It contains codes thanks to which you can control any device in the system, ports and disks. The BIOS is hardcoded into a ROM (ROM) chip on the motherboard. In most cases, at system startup, data is copied from ROM to RAM, the performance of which is much higher.

BIOS is standard, works flawlessly. However, in situations where the microcodes are not sufficiently developed, there is a discrepancy between the motherboard and integrated devices, more modern equipment appears, and it becomes necessary to reinstall the BIOS.

What is required to reinstall the BIOS?

To flash the BIOS, you will need specialized utilities developed by the motherboard manufacturer or other companies. With the help of these installation products, all the necessary firmware is entered into the CMOS chip. It is advisable to use the "native" utilities that are available on the disk supplied with motherboard, since they are fully adapted to specific equipment and exclude the possibility of failures or errors.

Since CMOS in modern motherboards is something other than flash memory with microcodes and settings, in order to correctly install the BIOS, you need to find a file with its corresponding version and a flasher program.

By the way, it is better to flash the BIOS from Windows, because it is more convenient. A similar operation from DOS will take a long time, require some ingenuity, although it is more reliable. Moreover, here you will have to create boot floppy with flasher and BIOS firmware.

And a few more important nuances. Before starting work, it is important to make a backup of the current BIOS version to external media using a flasher program. This will allow you to revert to the old version of the software in case of failure.

It is necessary to provide a stable power supply due to the "uninterruptible power supply". Otherwise, sudden sudden power surges will reduce all work to NO.

At per BIOS firmware from Windows, you will have to close all active applications and disable antivirus programs.

What do you need to be prepared for if you need to install a new BIOS?

Even a minor mistake in flashing the BIOS can cause serious complications. Therefore, you should prepare in advance to eliminate them. In particular, if the power is turned off or the system hangs, you will have to use the programmer. Although in this case it is advisable to turn to specialists.

With an incomplete BIOS flashing, it is rational to use the following method:

We remove CMOS from a similar working motherboard turned on.

We put several threads into the nest, thanks to which it will subsequently be easy to remove the microcircuit.

Install the damaged CMOS, damaged analog.

Run the firmware

When the motherboard is off, we make a reverse exchange of microcircuits.
