The massive transition to UEFI (Unified Extensible Firmware Interface) has already begun. Microsoft requires this interface to be used on all computers that will ship with Windows 8. More precisely, we are talking about UEFI with the function Secure Boot. At the same time, only “eight” can work on such PCs without problems: neither Windows XP nor “seven” can be installed on a UEFI machine without additional manipulations. You won't be able to boot from a Linux Live or Windows flash drive either. What exactly can happen if you try to start from an installation flash drive on a laptop? Sony VAIO, shown in the picture above. And the problems with UEFI don't end there. Each hardware manufacturer configures UEFI at its own discretion, thereby creating unnecessary difficulties for the user. The IdeaPad laptop from Lenovo was not able to recognize the same flash drive as boot media at all. At the same time, Lenovo has nothing to reproach: the fact is that the bootable flash drive is formatted in file system NTFS, and UEFI does not support booting from such media. If you connect the same drive to an EliteBook laptop from HP, it will boot without problems and allow you to install Windows. The problem is that all the data on the EliteBook disk would be deleted after installation.
Everyone configures differently
Are you confused? No wonder: UEFI with Secure Boot establishes new rules for installing and booting operating systems, and hardware manufacturers interpret these rules in their own way, which creates additional difficulties for the user. Therefore, in this article, we set ourselves the goal of clearing up the confusion around UEFI. Using laptops from major manufacturers as an example, we will tell you how UEFI works, what role the Secure Boot function plays, how to bypass the “traps” set by the new interface, and what you need to use bootable flash drives without fear of any destructive consequences.
How UEFI works
UEFI boots strictly according to established rules. If the OS does not support UEFI, BIOS emulation mode is activated. The process of booting a BIOS-based PC is quite simple: after pressing the power button, the BIOS starts, which checks the status of the hardware and loads the firmware - simple drivers for individual hardware components. The BIOS then searches for the OS bootloader and activates it. This in turn loads the operating system or displays a list of available operating systems.
UEFI-based computers boot in a similar way only until the boot options are searched. After this, everything happens differently. UEFI has its own OS boot loader with integrated launch managers installed systems. For it, a small partition (100–250 MB) is created on the disk, formatted in the FAT32 file system, which is called Extensible Firmware Interface System Partition (ESP system partition). It contains drivers for hardware components that can be accessed by the running operating system. The general rule is that, with the exception of DVDs, UEFI can only boot from media formatted with the FAT32 file system.
UEFI is a complex mechanism
ESP has its advantages: thanks to UEFI drivers and the OS loader, Windows starts faster and responds more adequately to critical errors drivers. But the UEFI interface also imposes restrictions: it allows you to install the OS only on hard disks, which are marked according to the GPT standard. The latter is not supported by any BIOS version, since, unlike the traditional partitioning scheme (MBR), it uses 64-bit sector addresses. In addition to Windows 8, only 64-bit versions support the UEFI interface Windows Vista and 7, as well as Linux with kernel 3.2 and higher. Moreover, for PCs certified to work with G8, Microsoft company requires the use of the Secure Boot option. In this mode, UEFI only launches verified OS boot loaders that contain Microsoft digitally signed drivers.
Along with Windows 8, only the Shim bootloader (Linux) has drivers with the necessary signatures for Secure Boot. They are not available in other OSes. Therefore, if you want to install Windows 7 or Vista on such a computer, in addition to G8, you need to open the UEFI menu and disable Secure Boot. If you choose a non-UEFI compatible OS as your second OS, you will need to use the Compatibility Support Module (CSM), which can be enabled in UEFI. Unfortunately, manufacturers use different versions of UEFI, and it can sometimes be difficult to figure out how to disable Secure Boot and enter BIOS emulation mode. We will consider these questions further.
UEFI based PC boot process
Depending on the configuration, UEFI either boots the computer itself or goes into emulation mode of the standard BIOS. Only after this does the Windows Boot Manager start.
Installing Windows on a PC with UEFI and Secure Boot
On a PC with Windows 8 based on UEFI Secure Boot, other versions of the OS can be installed only under certain conditions. The user must select in advance correct mode download and prepare the installation flash drive accordingly.
Enabling BIOS emulation mode
Complete confusion: the method for entering BIOS emulation mode depends on the UEFI version. On Sony VAIO (1) you need to activate the “Legasy” option, on ASUS Zenbook(2) - “Launch CSM”.
UEFI setup
Each manufacturer uses its own version of UEFI in laptops and ultrabooks. However, it does not provide access to everyone. necessary functions. Often, when loading a PC or laptop, the display does not display the name of the button that can be used to open the UEFI settings menu. We suggest doing the following: in the Metro interface, go to the “Options | Change PC settings" in the sidebar and activate the "General | Special download options." After the restart, the OS boot manager will appear, which will allow you to open the UEFI menu. The exception is HP's UEFI, which does not have this option. The following will help: while loading, hold down the "Esc" key. In any case, you must first find out which button allows you to enter the UEFI menu. If you change the boot mode to CSM or Legasy BIOS to boot from a rescue flash drive, you must switch back from CSM to UEFI after the recovery operation, otherwise Windows 8 will not start. But there are exceptions here: Aptio Setup Utility on ASUS computers activates UEFI automatically in the absence of BIOS-compatible bootable media, so you just need to disconnect the flash drive.
Disabling Secure Boot will be required if, in addition to G8, you want to install a 64-bit Windows version Vista or 7. Sometimes the so-called hybrid mode is supported, as in devices from HP, in which UEFI can boot from all bootable media and, if necessary, switch to BIOS mode. In the widely used UEFI version InsydeH2O, this depends on whether the laptop manufacturer has provided the ability to disable Secure Boot or not. IN Acer Aspire S7 this function is not available, and to deactivate it you need to switch from UEFI to BIOS mode and back.
Difficulties with recovery
With the advent of UEFI, manufacturers changed the way they work with the OS recovery system. The “Alt+F10” keyboard shortcut, which was previously used, for example, in Acer models, no longer works or is assigned to other functions. And the “F9” button loads on the new Zenbook not the ASUS Preload Wizard, but the program Windows recovery 8 with extended boot menu.
The VAIO Care recovery mode in Sony laptops can be opened in a similar menu by selecting the “Control Panel | Troubleshooting | Recovery". But if you start the OS boot manager and select “Diagnostics | Restore" or "Return to the initial state", the device will ask you to insert the original Windows disk 8, which is not included in the package. On Acer models, backup is performed using a pre-installed Windows program, and restoration from backup copy carried out from an external USB drive. However, you must first go to the UEFI menu and specify such a disk as a boot one.
Going to the UEFI menu from Windows
If the function is activated Windows startup 8 with advanced settings, then by selecting “Diagnostics” (1) and “Advanced Settings” (2), you can access the “UEFI Firmware Settings” menu (3).
Useful features UEFI
Every laptop manufacturer uses different versions interface UEFI and implements it in the system in accordance with its ideas. The table, broken down by model, will show you where the main UEFI features are located.
Solving the problem: disabling Secure Boot
In some cases, Secure Boot cannot be deactivated directly. In Acer Aspire S7, for example, this function is not available. But if you switch to “Legacy BIOS” (1) and back again (2), Secure Boot will be disabled.
Everything is possible in hybrid mode
HP's version of the UEFI interface supports hybrid mode, in which, depending on the boot media, one of two modes is launched - either UEFI or CSM. In this case, the Secure Boot function is disabled automatically.
Run from a flash drive
Older flash media for emergency boot and recovery only work in BIOS mode. We will make them UEFI compatible.
USB flash drives in Lately increasingly used as bootable recovery media or Windows installations. This is due to the fact that modern laptops rarely have optical drives. If you have studied UEFI settings on your computer, it is also recommended to upgrade your flash drives. With the advent of UEFI, all existing bootable flash drives can no longer be used in the usual way. For example, if you created a bootable USB media using UNetbootin, you will need to start your PC in CSM mode. The same applies to all old flash drives, since the developers Linux distributions Live (for example, GParted) only began to add a bootloader with UEFI support and Secure Boot functions in the latest, most recent versions of their applications.
The simplest method is to disable Secure Boot in UEFI, then use free program Rufus creates a UEFI compatible flash drive and then copies it to it latest version GParted.
The Microsoft program is outdated
Regarding bootable USB media with operating system Windows system slightly different rules apply. To be UEFI compatible, they must be formatted with the FAT32 file system. Many users, even for Windows 8, create bootable drives on flash drives formatted using a program from Microsoft, part of the “seven”. However this application by default formats the drive as a file NTFS system, as a result of which the system on the media cannot subsequently be installed on a computer with UEFI. To avoid waiting for an updated program from Microsoft, you can create a bootable drive manually. To do this, first format the USB flash drive using free utility. Then open the ISO image in Windows 8 and copy the files it contains to the media.
But in order for a UEFI-compatible flash drive with 64-bit Windows 7 to boot without any problems, you will need to copy the UEFI boot loader to the desired directory on the flash drive. To do this, using the free 7-Zip archiver, find in ISO image, which contains setup files Windows 7, in the Sources folder, install the archive file Install.wim and open it. After that, copy the bootmgfw.efi file from the 1\Windows\Boot\EFI directory. Then save it to your flash drive in the efi\boot directory and rename it bootx64.efi. After this, you can work with the USB drive in UEFI mode, and you will be able to install Windows 7 from it without any problems.
Creation bootable flash drives based on Live systems
To be compatible with UEFI, flash drives must be formatted in FAT32. For example, the UNetbootin (1) program creates bootable drives based on Linux Live distributions, formatting them in FAT. However, the Rufus utility (2) offers a more correct option.
Flash drive for OS recovery on PC with UEFI
Flash drives based on recent Live systems, such as GParted, can easily access UEFI PCs, since their built-in tools - such as GPart (1) and TestDisk (2) - can work with GPT partitions.
Formatting bootable flash drive with Windows
The 64-bit version of Windows 7 can also be installed on a PC with UEFI. If you want to perform this operation from a USB drive, you need to format it using the Windows DiskPart program in the FAT32 file system and make it bootable.
Removing the UEFI Boot Loader
A UEFI-compatible flash drive running Windows 7 additionally requires a UEFI boot loader - bootmgfw.efi. It must be manually copied from the install.wim archive to a flash drive using 7-Zip or any other archiver.

Nowadays it’s difficult to find a person who doesn’t know, at least by hearsay, what it is BIOS. Indeed, computers have long been firmly established in our apartments and offices. And if we take into account the pathological passion of the Russian person to get into everything with the slogan “what’s there to repair?!”, then I think everyone is familiar with the screen BIOS has not raised any special questions for a long time. Judge for yourself - significant changes in BIOS whole decades did not bring him - he remained outwardly the same all the time.
Here's the blue one Award:
But the gray ones Phoenix And AMI:
Several generations of people grew up on them, and they practically did not change in appearance at all. But still, evolution has reached BIOS- appeared EFI, and behind him UEFI.
What is UEFI?
EFI (« Ifai» — Extensible Firmware Interface) is an interface for communication operating system and microprograms that control equipment at a low level. In other words EFI correctly initializes the hardware when you turn on the computer and then transfers control to the operating system. Interface EFI was originally developed by Intel for Intel-HP Itanium systems in the early 2000s, as a replacement for the old BIOS. Indeed, existing hardware limitations made normal operation impossible. large servers on Itanium processors. Several versions have been released EFI, after which Intel introduced this specification into UEFI Forum, who is now responsible for the development and promotion of EFI. By the way, the name of the interface was also changed a little - it became Unified Extensible Firmware Interface - UEFI. Currently the most current specification UEFI carries an index 2.3.1 .
What are the main advantages of UEFI?
First, a very significant advantage is the specification UEFI is the only option to support hard drives larger than 2 TB.
Second the advantage is that UEFI, unlike the classic BIOS, not just microprogram hardwired into a special chip - it’s whole interface located in the directory /EFI
, which can be located both on the chip and on the section hard drive and even on a separate removable disk. Those. V UEFI Any adapted programs can be added. Already now from under UEFI BIOS Some manufacturers have the ability to access the Internet. Certainly PPPoE or L2TP UEFI will not be able to raise it, but getting an IP address via DHCP from the router is quite possible. Accordingly, the capabilities and downloads over the network are expanding.
Third- ability to integrate drivers into UEFI. This driver will be relevant for any operating system that will be installed on the computer, providing versatility and cross-platform functionality.
Fourth- very nice interface. This is no longer the modest ascetic interface of the old BIOS. For example, here is the so-called 3D BIOS from GIGABYTE:
Everything is clear, understandable and beautiful.
There is even a choice of language. True, unfortunately, the language of the 6th landmass of the globe is not yet taken into account by all manufacturers.
Another significant plus for many new system- much more fast loading operating system than when using BIOS. True, the operating system must also fully support UEFI. And so far only he can do this well Windows 8.
Basic UEFI BIOS settings:
According to the configurable parameters themselves and their values UEFI BIOS- it's the same one BIOS. I won't consider the interface UEFI each vendor - this is not necessary, since the requirement to comply with the specification does everything UEFI BIOS logically similar, despite the fact that the external interface may differ in the arrangement of elements.
In most cases the interface UEFI made in such a way that by default only system information and the simplest basic settings— loading order, operating mode:
To select the device from which to download. Just click the icon Boot Priority and choose required device, from which the download will be carried out.
In some cases, for example, MSI may also have tools for quickly overclocking the system:
To go to advanced settings UEFI BIOS You need to click on the Advanced Mode button.
And here we already see the parameters of the good old BIOS.
In advanced mode, there will definitely be a section responsible for overclocking and operating modes of the processor, memory and power management system. It may be called OC Tweaker, AI Tweaker or H.I.T..
Also, there will definitely be a section Advanced
, consisting of 5-7 sections. Alternatively, some manufacturers, for example Gigabyte, there may be three sections instead of one: System, Peripherals And Power Management.
IN System— basic settings of the processor, memory controllers, ports:
Fulfill BIOS setup computer is welcome in the following cases:
- Building a PC from scratch;
- Replacement of components;
- Availability of integrated graphics in the CPU;
- Overclocking the CPU and random access memory;
- Fan operation settings system unit;
- Enable audible emergency alerts;
- Reinstalling the operating system.
Setting up BIOS for Gigabyte motherboards
To login Board BIOS from Gigabyte, when booting the computer, press the Del key. On home page (M.I.T.CurrentStatus) we will see the current BIOS version, the system bus frequency multiplier, the CPU and RAM frequencies, the amount of memory, the temperature and voltage of the central processor.
RAM
At the beginning of 2018, the most common type of RAM for PCs is DDR4, the frequency of which reaches 4266 MHz, which is much higher than DDR3. Default RAM memory operates at a frequency of 2133 MHz. Therefore, it is necessary to transfer it to a frequency that meets the specification. The frequency value is hardcoded into the X.M.P profile. To activate it, find the parameter Advanced Memory Settings, Further - Extreme Memory Profile (X.M.P.) and set the value to Profile1.
For enthusiasts, memory overclocking is available by changing timings ( Channel A/B Memory Sub Timings) and voltage ( DRAM Voltage Control).
Video adapter settings
At the next stage of setup, we focus on the graphics adapter. The tab will help us with this Peripherals. If the system unit configuration does not imply the use discrete video card, then we activate the graphics core built into the CPU: Initial Display Output– select IGFX. This adapter uses a certain amount of the computer's total RAM. To change its volume in the section Chipset click on DVMT Pre-Allocated and stop at the maximum possible value. And in DVMT Total Gfx Mem make the active size MAX.
If you have an external video card, the option Initial Display Output change to PCIe 1 slot (PCIEX16 slot) or PCIe 2 slot (PCIEX4 slot), and the value Internal Graphics in the submenu Chipset– to Disabled. This is done to reduce the load on the CPU. If you have two monitors, you can use two graphics adapters at once - external and built-in - the choice is up to the user.
Fan control
What is most important – maintaining the lowest possible temperature inside the case or silence? The answer lies in the type of video adapter used. If it generates a lot of heat (from 150 watts), then the hot exhaust air must be removed from the housing as quickly as possible. This is done by coolers located in front, behind and at the top of the system unit. They are connected to the corresponding connectors on motherboard. But for undemanding tasks, modern graphics adapter consumes little energy. Therefore, in the large section M.I.T.\PC Health Status in the submenu 1 st System Fan Speed Control, 2 nd System Fan Speed Control And 3 rd System Fan Speed Control set the Normal parameter, which will automatically change the rotation speed of the blades based on the temperature in the system. You can also activate your own graph of this dependence by selecting Manual. These values are set in the subsection Fan Speed Control for each cooler. If the adapter built into the CPU core is responsible for video graphics, then to reduce noise we use the silent mode – Silent.
In the same section the parameter CPU Fan Speed Control (CPU_FAN Connector) is responsible for regulating the rotation speed of the processor cooler. The following options are available: Normal (automatic operation depending on the temperature of the CPU cores), Silent (fan runs at reduced speeds), Manual (manual control), Full Speed (maximum possible degree of rotation).
Alarms
The specifications of central processors imply their operation up to 100 ºС. But the lower the temperature inside the CPU, the longer it will work. Therefore, the BIOS suggests setting a threshold value for this parameter, upon reaching which an alarm is triggered. Find it in the menu M.I.T.\PC Health Status line CPU/System Temperature Warning. By default it is set to Disabled. For processors with low heat generation, it is recommended to change it to 70 ºC/158 ºF, and for “hot” ones – 90 ºC/194 ºF. This parameter depends on how effectively the cooler removes heat from the processor cover. This setting also applicable for case cooling fans.
An alarm will also occur if any of the fans malfunction and are incorrectly connected to the connectors on the system board. To enable this function in the same section, look for CPU/CPU OPT/System Fan Fail Warning and change to Enabled. Recently, coolers with a semi-passive operating mode have begun to appear on the market. With a small load on CPU they don't rotate. In this case, it is advisable to leave the default value - Disabled.
Optimizing the performance of peripheral devices
To install the operating system, it is necessary that the computer, when starting, access the disk where the operating system distribution is located. You can set these parameters in BIOS Features, going to Boot Option Priorities, where we select HDD, SSD, USB or DVD as the first boot disk.
The system is now usually installed on a solid state drive, which works best in AHCI mode. You can activate it in the section Peripherals - SATA Configuration and its subsection SATA Mode Selection. Same here, but in a submenu External SATA turn on external devices with SATA interface.
Any motherboard has a built-in audio controller. If the user is not satisfied with the sound quality, he adds an external sound card. Then you need to disable the integrated sound in the menu Chipset – Audio Controller.
The final stage
Confirmation or cancellation of BIOS changes made is done in the section Save &Exit:
- Save &Exit Setup– saving corrections and exiting;
- ExitWithoutSaving– exit without making amendments;
- Load Optimized Defaults– loading the optimal default settings that are required after BIOS updates or clearing CMOS parameters.
Setting up BIOS for Asus motherboards
To enter the BIOS of the Asus motherboard, press Del or F2. There are two modes available here − EZ Mode And Advanced Mode. Loads by default EZ Mode. To go to the second state, you need to find the corresponding link below or use the F7 key. Let's take a closer look Advanced Mode.
Options responsible for the operation of coolers in the system are located in QFan Control (F6). There are pre-installed and manual profiles for processor and case fans: Standard, Silent, Turbo, Full Speed, Manual. In manual mode, you can plot the dependence of the degree of rotation of each cooler on temperature.
You can disable the cooler control function in the menu Monitor\Q-Fan Configuration. It is also possible to regulate 3-pin fans by selecting DC Mode.
Utility EZ Tuning Wizard (F11) allows you to overclock the processor taking into account its cooling type. This is relevant for owners Intel processors with index K. In the submenu OS select a scenario for a computer for everyday use (Daily Computing) or a gaming PC (Gaming/Media Editing). Then click on the icon with a box, tower or liquid cooler and start the tuning process.
Activation of the XMP profile for RAM occurs in the submenu.
For graphics built into the CPU, it is necessary in the section Advanced\System Agent (SA) Configuration\Graphics Configuration\Primary Display set the value to IGFX, and for a discrete video adapter - PEG.
Operating mode of drives with SATA interface configured in Advanced\PCH Storage Configuration\SATA Mode Selection. Select AHCI. Here's the point S.M.A.R.T. Status Check provides condition monitoring hard drives and notifies about errors in their work.
The speed of SSD devices decreases over time as free space fills up. Utility Secure Erase on the menu Tool optimizes work solid state drives, thereby returning them to their original performance.
Information about all connected storage media can be viewed in Advanced\HDD/SSD Smart Information.
Enabling/disabling the audio controller built into the motherboard is carried out in the submenu Advanced\HD Audio Controller.
The priority for loading devices is set in the menu Boot\Boot Option Priorities.
Saving and canceling changes made to the BIOS, loading optimal factory settings is available in the main menu Exit.
Setting up the BIOS is important for those who want to get the most out of their computer configuration. Therefore, before installing the operating system, you need to study this procedure in detail, which is described in the instructions supplied in the box with the motherboard.
Unified Extensible Firmware Interface or UEFI is a firmware code that acts as an intermediary between computer hardware and the operating system, which replaced the BIOS with the release of Windows 8.
UEFI, like BIOS, is responsible for setting up and initializing devices when the PC is turned on and provides them with the ability to exchange data between themselves and the system. The UEFI functionality is focused on the most modern platforms - disk drives with GPT partitioning and 64-bit versions of the OS, mainly Windows 8 and Windows 7. But adherents of alternative, 32-bit and obsolete systems (like Windows XP) also did not lose the opportunity to “use” » favorite software, except that now installing it on the machine has become a little more difficult.
One of the main differences between UEFI and BIOS is a programmable interface, that is, it is a separate, small “OS” from which you can access the Internet and perform a number of administrative tasks (computer diagnostics, hardware configuration, running programs from CDs, platform update, etc.) to a much greater extent than can be done in the BIOS. Other important innovations are the graphical shell in which the mouse works and support for national languages.
BIOS also did not cease to exist with the release of the new platform - it “moved” to UEFI and, if necessary, can be launched - for this purpose, the new platform provides a BIOS emulation mode. Emulation is used precisely for Windows support XP and 32-bit versions of other OS.
Loading the operating system from a flash drive or bootable DVD
Just like old versions of BIOS, new versions of UEFI BIOS differ greatly from each other in design, location of tabs, settings and set of capabilities.
We especially note that a computer with UEFI can only boot from DVDs or media formatted in FAT32.
It is important to remember this when creating installation flash drives.
1. Load the BIOS. At the beginning of the computer boot, you need to start a special button for UEFI to appear:
ASUS/F2
ACER/F2
HP/Escape or F10
SONY / Assist button
2. For a better understanding, let’s turn on the BIOS display mode in Russian.
Open the list of languages in the upper right corner by clicking on the arrow opposite English.
Main window - select Russian language
(Picture 1)
3. If you are using a UEFI compatible flash drive, skip this step. To boot from a non-UEFI compatible device, you will need to disable Secure Boot.
Secure Boot is a security option that prevents the execution of boot code that is not signed by Microsoft.
Secure Boot is only supported by bootloaders for Windows 8 and some Linux distributions.
In many UEFI configurations, you must enable BIOS mode before disabling Secure Boot. This option is located in the “Boot” or “System Configuration” tab and can be identified by the words “CSM” or “Legasy”. The full name in different editions of UEFI is written something like this: “Launch CSM”, “Legasy BIOS”, etc.
(Figure 2)
In “stripped-down” UEFI, after enabling the BIOS mode, parameters that were not even displayed “by default” become available. Among them is Secure Boot, located in the “Security” menu or submenu. To turn it off, you need to switch it to “Disabled” mode. After this, the computer will be able to boot from a drive that is not UEFI compatible. Booting from USB is usually already enabled. 
(Figure 3)
4. Select boot from flash drive or DVD.
Press the “Boot Menu” button or F8 and in the “Boot Menu” dialog box that appears, select the device from which Windows will be installed.
(Figure 4)
If you select HDD or DVD drive instead of a flash drive, you can reboot again, go into the BIOS and change the choice.
5. To exit UEFI and save the settings, click the “Exit - Save Changes” button or click the item of the same name in the menu. The F10 key also works in BIOS mode.
If you select a download source, the system may not offer to save changes, but will immediately begin downloading from the device.
Uefi interface: tab navigation
In graphical versions of UEFI, the main window (Figure 1) usually displays the system time, platform information, and a number of hardware monitoring readings (device voltage and temperature, fan speed). To access the main settings, you need to switch to the “Advanced Mode” (F7) by clicking the button with the same name.
In the advanced mode of full-featured UEFI configurations, as well as abbreviated ones, the following tabs are present:
(Figure 5)
Main / Basic
Advanced / Additional
Security / Security
Boot
Tools/Service
Exit
Some others, such as Ai Tweaker or Monitor, are not available everywhere - mostly only on stationary motherboards. They provide access to utilities for overclocking a PC and system monitoring. Since mobile platforms (laptops) cannot be overclocked, these functions are not available on them.
Let's look at the parameters of the main tabs
a) Main
Here, as in the BIOS, the parameters of the main PC devices are displayed - processor, memory, drives, laser drives and others, as well as the system time and date. This tab contains the language selection option.
The connected drives submenu displays detailed information about them.
Some of the options Main section you can switch and customize, but not everything.
b) Advanced / Additional
This section contains advanced PC hardware settings. Listed below are which ones.
Processor(s) details:
type;
clock frequency;
number of cores;
cache;
supported technologies, etc.
Plug and Play devices, configuration of SATA, video, PCI, peripherals, USB, integrated devices on the motherboard and peripherals.
In the absence of a separate “Power” tab, power supply parameters are configured in this section; in particular, energy saving functions and the behavior of the power supply in the event of a power failure are enabled here.
In the same section there is usually an option to reset hardware configuration data.
c) Security
Here you can find the option to turn Secure Boot on and off, as well as settings for access rights, passwords, etc. In some versions UEFI partition Security is present as a submenu of the Main tab.
The startup section contains:
option to enable BIOS mode;
order of polling boot devices;
Full Screen Logo - option to display the PC manufacturer's logo on the screen during POST;
Numlock Status - selecting the operating mode of the NumLock key during PC boot;
Boot-time Diagnostic - monitoring boot time and optionally a number of other settings.
e) Tools / Service
This frequently present but non-persistent tab contains the PC manufacturer's proprietary hardware management utilities. Here you will usually find a UEFI update option and a mini-browser that allows you to access the Internet to the manufacturer’s website.
f) Exit / Exit
This section can be in the form of a separate tab or button at the top of the screen. It contains various options for exiting UEFI:
Exit Saving Changes (save settings and exit);
Load Setup Defaults or Load default settings (restore default settings);
Exit Discarding Changes (exit without saving settings);
Discard Changes (cancel changes without exiting);
Save Changes (save changes without exiting).
Asus Ez Mode ( turn off “Advanced” mode and return to the main window)
What to do if UEFI changes make your computer run worse
Sometimes, after reconfiguring a number of UEFI parameters, the computer starts to work slower or refuses to load the OS at all. It can be difficult to remember what and where you changed with such an abundance of various options. To return everything to its place - restore the default settings, you can use one of the methods described below.
Load UEFI, open the “Exit” menu and click on “Load Setup Defaults”.
Disconnect the PC from the power supply, remove the cover of the system unit, find the CMOS battery on the board, remove it, short-circuit the terminals of the battery socket, and then return it to its place.
Find the CLRTC jumper on the motherboard (other names are CRTC, Clear CMOS, CCMOS, etc.), designed to reset the BIOS/UEFI settings. Place it on adjacent contacts and after half a minute return it to its previous position. Some boards have a special button for the same purpose.
