What is BIOS and its settings. How to configure the BIOS to boot from a disk or flash drive Graphically

Hello, dear readers! Today we will talk about one seemingly complex topic, which will sound like this: UEFI Boot - what is it? and how to disable UEFI in BIOS.

Of course, for the average user, all these names and abbreviations mean nothing, but nevertheless, when buying modern desktop computers and laptops, you will still come face to face with these concepts.

Yes, friends, this is the same settings section on a blue background, which you can enter at the very beginning when you turn on the computer. Here's a picture to refresh your memory:

Many more enthusiasts here have tried to play with the voltage and frequency of the main processor in order to increase the power of their machine. So, the BIOS microprogram was replaced by another, more modern one.

And as you already understood, it is called UEFI. Among the new innovations in it, we can note support high resolutions screen, very large disks and working with a mouse.

If you read all the lines above and did not understand anything at all, then watch a short video to reinforce the topic:

So, it should definitely be said that a full-fledged UEFI system has not yet been implemented in all modern computers. But some of its new functions, hitherto unseen, have been successfully implemented into the old BIOS shell.

And one of them is the so-called UEFI Boot (full name Secure Boot). The purpose of its work is to prevent substitution of the system boot source, thereby reducing the use of unlicensed software.

That is, the picture turns out to be such that now we will not be able to boot, for example, from a flash drive or a third-party drive. Indeed, in this situation, they simply will not be in the list of available devices:

But really, decide this problem it is possible and very easy. To do this you need to make a couple of settings and that’s it. So let's get to work. So to speak, enough theory.

And in order to disable UEFI functions in the BIOS, you must immediately enter it. As mentioned above, to do this you need to press a certain key combination immediately after turning on the computer.

Thus we disabled main function UEFI protection from third-party bootloaders. Then you should go to the “Boot” section and set the parameters as in the screenshot below:

After this, we should have a list of available devices. Now, by changing their position in the list, you can manipulate download sources. Again, using the author’s example, this can be done with a keyboard shortcut Fn+F5/F6:

Well, after all the parameters have been entered, all that remains is to save the changes. This is done in the "Exit" menu by selecting "Exit Saving Changes":

That's all, my friends, now you know exactly the answer to the question: UEFI Boot - what is it and how to disable UEFI in the BIOS. If you have any questions, feel free to ask them in the comments.

Well, if you suddenly want to learn more about UEFI BIOS, then watch a short video where this topic opened more widely.

USB ports may stop functioning if the drivers are lost, the BIOS settings are damaged, or the connectors become damaged. mechanical damage. The second case is often found among owners of a recently purchased or assembled computer, as well as among those who decided to install an additional USB port on the motherboard or those who previously reset the BIOS settings.

BIOS is divided into several versions and developers, therefore, each of them may have a significantly different interface, but the functionality for the most part remains the same.

Option 1: Award BIOS

This is the most common developer basic systems I/O with standard interface. The instructions for it look like this:

Option 2: Phoenix-Award & AMI BIOS

BIOS versions from developers such as Phoenix-Award and AMI have similar functionality, so they will be considered in one version. Instructions for setting up USB ports in this case look like this:

Option 3: UEFI interface

UEFI is a more modern analogue of BIOS with graphical interface and the ability to control using the mouse, but in general their functionality is very similar. The instructions for UEFI will look like this:

Connecting USB ports will not be difficult, regardless of the BIOS version. Once they are connected, you can connect a USB mouse and keyboard to your computer. If they were connected before, their operation will become more stable.

Let's look at this instruction on how to disable compatibility mode in the operating system. Windows system. A special compatibility mode allows you to run older programs in new version Windows.

Many users use it to work on a computer software, the last releases of which were released quite a long time ago. It happens that the developer has stopped supporting the application, the program is not updated for some reason, and in the meantime a new version of the OS has been released. Until the transition to a new version of Windows, the program works and fully satisfies the user's needs.

After installing a new version of Windows or after upgrading to Windows 10 from previous versions Windows 7 or Windows 8.1, it turns out that some programs do not work on the computer. To run older applications that work fine in previous versions operating system, Windows compatibility mode is used.

In some cases, the user needs to disable Windows Compatibility Mode. For example, a new version of an application has been released that supports a new version of Windows, or because this mode interferes with the operation of some programs.

Sometimes messages appear stating that the program is running in compatibility mode, so the user is faced with the question of how to disable this mode separate program or disable the mode altogether on the computer.

Compatibility Mode Windows programs You can disable it in two ways:

disable program compatibility mode
disable compatibility mode in operating system Windows

In the first case, compatibility mode will be disabled for the individual program. In the second option, the system service responsible for program compatibility on the computer will be disabled.

To disable Program Compatibility Mode in Windows, you can use several methods: from “Manage Services”, disable the “Program Compatibility Assistant Service”, disable it using the Local Editor group policy", or by disabling the service in the system configuration.

How to disable compatibility mode for a specific program (method 1)

To disable compatibility mode for a specific program, follow these steps:

Right-click on the shortcut or program file. IN context menu select "Properties".
In the Properties: Application Name window, open the Compatibility tab.
In the “Compatibility Mode” section, uncheck the box next to “Run this program in compatibility mode for:”, and then click on the “OK” button.

After this, the compatibility mode for this application will be turned off in the Windows operating system.

Disabling the Compatibility Assistant service in the System Configuration application (method 2)

The easiest way to disable the Program Compatibility Assistant service in Windows is to use system program System configuration.

Make the following settings:

In the search engine Windows line enter the expression: "msconfig" (without quotes), and then run the system utility.
In the System Configuration window, open the Services tab, find the Program Compatibility Assistant Service service.
Uncheck the box next to “Program Compatibility Assistant Service”, click on the “Apply” and “OK” buttons (In Windows 7, the service is called “Program Compatibility Information”).

Restart your computer.

After the computer starts, the Program Compatibility Assistant service will be disabled in the Windows operating system.

Stop the Program Compatibility Assistant service (3rd method)

Another way: disabling local services Compatibility Assistant services in the Windows operating system.

Configure the following settings:

Press the “Win” + “R” keys on your keyboard at the same time.
In the “Run” window, in the “Open” field, enter the expression “services.msc” (without quotes), and then click on the “OK” button to execute the command.
In the Services window, double-click on the Program Compatibility Assistant Service service.

In the Properties window: Program Compatibility Assistant ( Local system)", in the "General" tab, click on the "Stop" button if the service is running in this moment time.
In the Startup Type setting, select Disabled, and then click the OK button.

Disabling the Compatibility Assistant in the Local Group Policy Editor (method 4)

Users of the Windows operating system in editions: Pro, Enterprise, For educational institutions can use another method using the Local Group Policy Editor.

Go through the following steps:

Type "gpedit.msc" (without quotes) into the Windows Search box, and then launch Local Group Policy Editor.
In the “Policy” setting Local computer”” Open the “User Configuration” section.
Follow the path “Administrative Templates”, then “ Windows components", find the "Application Compatibility" policy.
Double-click on the “Disable Program Compatibility Assistant” option.

In the Disable Program Compatibility Assistant window, select the Disabled option, and then click OK.

Conclusion

If necessary, the user can disable Windows Program Compatibility Mode for an individual program or disable the Program Compatibility Assistant service in the Windows operating system in three different ways.

In the last article we talked about that. Now I'll tell you how to set it up Computer BIOS For Windows installations from a disk or flash drive.

1. What is BIOS and UEFI

Each motherboard has special program to boot your computer and configure settings various devices. This program is flashed (programmed) into a special chip on the motherboard and is therefore called firmware.

Previously, all motherboards had firmware called BIOS, which had a simple graphical interface with white letters on a blue background and was limited in functionality. For example, in the BIOS it was impossible to use the mouse, select a language, and there were no graphic elements (pictures) due to the limited capacity of the BIOS memory chip. Also, motherboards with BIOS did not support disks larger than 2 TB due to limitations of the old disk partitioning system (MBR).

Nowadays, many motherboards have a new type of firmware called UEFI, which features an improved graphical interface using a beautiful background, hand-drawn buttons, the ability to select a language (including Russian) and some improvements. For example, support for a new type of disk partition (GPT), which allows you to use hard disks volume more than 2 TB.

What type of firmware your motherboard has can be found in its manual on the manufacturer’s website motherboard or laptop, as well as visually when entering the Setup configuration program. The Setup program is also flashed into the motherboard and is used to change BIOS or UEFI settings.

2. How to enter BIOS Setup

To enter the Setup program, immediately after turning on the computer, press the “Delete” button on the keyboard. On some motherboards and laptops, the “F2”, “F10” or “Esc” keys are used for this. You can read which button to press in the messages that appear immediately after turning on the computer.

In text form

Graphically

If you don’t have time to read, then press the “Pause” button on your keyboard to pause the download. You can continue loading by pressing any key. If you press the key designated to enter Setup, you will immediately be taken to the motherboard setup program.

UEFI interface

3. Basics of working in Setup

3.1. Control keys

The Setup program is a set of various parameters, grouped on separate tabs, depending on their purpose. On the right or below there will be a description of the keys with which all actions are performed.

To navigate between tabs, you usually use the “right” and “left” arrows on the keyboard. To move between lines within one tab, use the down and up arrows.

To change values, use the arrows to navigate to the required field, press the Enter key, and then use the arrows to select a new value from the drop-down menu. For this, the “+”, “-” or “Page Up”, “Page Down” keys can also be used.

To return up a level or to the previous page, press the Esc key. The “Esc” key on one of the main tabs will mean exiting the BIOS without saving the settings, which you will need to confirm or refuse to exit.

In the Setup program with the UEFI interface, you can perform all actions using the mouse.

3.2. Saving settings

This is a very important point. After making all the necessary settings, go to the “Exit” tab, select the “Exit and Save Changes” item using the arrows (“Exit and Save Changes”, the word order may be different), press “Enter” and confirm saving the settings by selecting the “OK” arrows or “Yes” and “Enter” again.

You can save the settings much easier and faster by pressing the “F10” key on the keyboard and confirming your decision. This key works in many versions of BIOS, UEFI and is often indicated in tooltips (bottom or right).

3.3. Cancel Settings

If you accidentally changed something or are not sure about the correct settings, then go to the “Exit” tab and select “Exit and Discard Changes” or press the “Esc” key until a message appears about exit without change settings and confirm the action (“OK” or “Yes”).

3.4. Restoring settings

To restore all settings to optimal defaults, go to the “Exit” tab and select “Load Setup Default”. After this, you can immediately change other settings or simply exit the BIOS and save the settings (“Exit and Save Changes” or “F10”).

4. Download options

Insert a bootable disk or flash drive into the computer on which you plan to install Windows. Now, in order to start installing Windows, you need to configure the BIOS (or UEFI) using the Setup program to boot from a disk or flash drive. You can also use the special boot menu of the motherboard (Boot Menu) for this. The last option is simpler and more convenient, but we will consider both methods.

5. BIOS setup

5.1. Changing boot priority

Go to the "Boot" or "Download" tab.

Install your DVD drive or flash drive first in boot device order.

If you install Windows from a disk, then the first item is to select a device like “ATAPI CD-ROM”, a name indicating the manufacturer or model of the drive. For example, “CDROM:PM-HL-DT-STDVD-RAM GH22NP” (this is an LG DVD drive).

If you plan to install Windows from a flash drive, then first choose something like “Removable Dev.” or the name of the flash drive indicating the manufacturer. For example, “USB: Patriot Memory” (this is a “PATRIOT” flash drive).
Transcend JetFlash 790 8Gb

The second one should be HDD, which is designated as “Hard Drive”, “HDD” or the interface to which it is connected, the manufacturer and model of the disk. For example, “SATA:3M-SAMSUNG HD502HJ” (this is a 500 GB Samsung hard drive with a SATA interface).

Please note that in the “Boot” section there may be other items responsible for boot priority, such as “Hard Disk Drives” or “Removable Device Priority”.

They also need to check that the DVD drive or flash drive comes first.

If you have two hard drives, then the one on which you install the system should be higher. But in this case, I recommend disconnecting one of the disks to avoid confusion and possible errors in installing the system. It can be connected after installation.

In the Setup program with the UEFI interface, everything is done similarly. Look for the “Boot” or “Download” section, find your DVD drive or flash drive there and move it to the very top of boot priority. Plus, you can use a mouse for this, which is easier and more convenient.

5.2. SATA controller operating mode

In principle, this is not so important, but many people are interested in this issue, so I decided to clarify it a little. SATA drives can work in compatibility mode with older IDE drives and in the more modern AHCI mode. AHCI gives a small performance boost hard drive with multiple simultaneous access to it. This mode of disk operation occurs mainly on servers and for ordinary home computer practically useless.

At BIOS setup it is possible to select the operating mode SATA controller.

These settings may be located in different places and have slightly different names, but the principle is the same everywhere. You are offered IDE compatibility mode or the new AHCI mode.

In general, IDE compatibility mode is recommended for Windows XP, since it does not natively have SATA drivers and simply will not see the hard drive, which will not allow Windows to be installed. Drivers can be built into the Windows installation distribution, but this makes no sense, since it will not affect the speed of operation and may add problems.

There is an easier and more convenient way to boot from a DVD or flash drive for both BIOS and UEFI - boot using the “Boot Menu”.

To call the boot menu, the “F8”, “F10”, “F11”, “F12” or “Esc” keys can be used. They can often be seen in tips on home screen computer boot. You can also find out this information from the instructions, on the website of the motherboard or laptop manufacturer, by searching on the Internet, or at random.

Immediately after turning on the computer, press and hold the “Boot Menu” key until the boot device selection menu appears.

Use the down and up arrows to navigate to the DVD drive or flash drive and press Enter.
Sandisk Cruzer

The advantages of this method are obvious - you don’t need to delve into the BIOS, you don’t need to return the BIOS settings back later (although this is not always necessary), and it’s enough to call this menu just once, since after you start installing Windows, this will no longer be needed. Additionally, using the "Boot Menu" does not change the BIOS or UEFI settings.

7. Download problems

Friends, due to the fact that many people had problems loading when installing Windows and some wrote about it in the comments, I decided to make a separate section where I collected methods known to me to solve these problems.

If the computer stops loading at the very beginning and asks you to press F1, after which it enters the BIOS, then you most likely either have a low battery on the motherboard (the timing may be off), a problem with the processor cooler (it’s broken, it’s not connected there) or hard drive(errors in SMART).
If, when you turn on your PC, the message “Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press a key” appears, this means that the boot area on the disk or flash drive is not found or is damaged. Try booting from installation disk or flash drives with using Boot Menu (section 6 of the article), if it doesn’t help, do it bootable media again using the Windows USB/DVD Download Tool.
If, after restarting the computer, the Windows installation starts from the beginning, then remove the boot disk or flash drive and restart the computer, the installation should continue from the hard drive.
Disconnect all unnecessary USB devices (flash drive, 3G modem, smartphone, printer) from the computer. You only need to leave the mouse, keyboard, DVD or flash drive from which you are installing Windows.
If you have several hard drives, then disconnect all drives from the motherboard, except the one on which Windows will be installed.
Reset BIOS settings to default (described in this article).
If the installer does not see the disk or error 0x0000007B appears at the end, change the SATA controller mode in the BIOS from AHCI to IDE or vice versa.
If every time you boot your computer or laptop itself enters the BIOS or opens the boot menu, then set the Boot Pop Menu option in the BIOS to Disable (if any).
Disable Fast Boot in the Advanced section of the BIOS, and in the Boot section set the Launch CSM option to Enable (if available).
In the Boot section of the BIOS, change the boot mode from EFI (UEFI) to Legacy (if available).
Set the Secure Boot option in the BIOS to Disable (if available).
Select in BIOS version installed Windows (if any).
If you have a laptop, one Windows version is installed, but the other one is not and the BIOS setup tips did not help you, then contact support or the manufacturer’s forum. Updating the BIOS can also help, after which additional options may appear in it (sections 8-12).
If possible, from a DVD, since there are many different problems with flash drives.
Make from .
Insert the flash drive into the USB 2.0 connector on the back of the computer (motherboard) or the USB 2.0 connector of the laptop. Booting from USB 3.0 does not always work.
Try using the Boot Menu, as described in paragraph 6 of this article. This method is simpler and more reliable than setting boot priority in the BIOS and you can determine whether the computer sees your flash drive.
An underscore on a black screen indicates that the computer freezes while accessing a flash drive or hard drive. If the download continues without a flash drive, then that’s definitely the problem.
If the computer does not see the flash drive or does not want to boot from it, use a DVD or other flash drive for installation.
If this is not possible, then change the type of flash drive from " removable media" to the "hard drive" using the "BootIt Next Generation" utility, format it with the "HP USB Disk Storage Format Tool" utility and make it bootable again using the "Windows USB/DVD Download Tool". You can download all these utilities below in the “Links” section.
If the problem occurs after selecting the Windows installation partition, then use the tips for setting up the BIOS (sections 7-12). When installing, remove old partitions from the disk or do it using boot disk Acronis Disk Director.
If the installer reports that it cannot install Windows on the disk, then try running it or back.
