Does not go into uefi windows 10. Bios settings - Detailed instructions in pictures. System restore via command line while the computer is on
The 10th version of Windows, along with numerous changes, brought difficulties with the transition to BIOS: during power-on, the stage with the login prompt is skipped by default. This is done to accelerate the preparation of the computer for work. Let's figure out how to log into BIOS on Windows 10.
How to enter BIOS on Windows 10: boot settings
There is a standard mechanism that still allows you to switch to BIOS at the initial stage of launch, but by default it is not active. Instead, a quick start mechanism is used, similar to hibernation: the OS goes into a deep sleep, from which you can quickly return to work. However, you can configure your system to prevent this from happening the next time you start it.
Through system parameters
The first way to open BIOS is to configure the boot features directly from the running Windows 10. To do this, open the menu by right-clicking on the taskbar and select the lowest item.
An alternative option, how to enter the settings, is available through notifications. You need to click on the notification icon on the taskbar and select the "All parameters" button in the window that appears.
A window will appear where you can configure Windows 10. It needs a section called "Update and Security".
And already in it the subsection "Recovery" is selected.
On the page that opens, you need to click the "Restart now" button in the special download subsection.
The device will then restart.
Through Start
Another option how to turn on BIOS is to go to Start and use the shutdown submenu located in it.
Through the login screen
There is another way to start the BIOS - right from the start screen with a password. It is useful if you cannot log into Windows 10 for one reason or another.
At the bottom right, you need to click on the power icon, hold down Shift and click on restart.
Further actions
After completing any of the above options, the PC will reboot and you will be prompted to select actions. You should go to the point for troubleshooting.
A diagnostic section will be displayed, in which you will need to go to Advanced Options.
Now you can click Restart.
After that, the device will restart, and the quick start mode (analogous to hibernation) will not be used. Therefore, you can press F2 or another appropriate key to enter the BIOS.
Please note: Other combinations may be used on a laptop. Therefore, carefully follow the messages before turning on the OS, they indicate which button should be pressed to work through the BIOS.
On modern computers, UEFI is more often used - it is similar to the BIOS, but makes full use of the capabilities of the PC (for example, you can use the mouse in it, and the graphics are richer). If Windows 10 is installed on a computer with UEFI, the corresponding item will be displayed.
It should be chosen to switch to UEFI.
Disable accelerated mode
Changing the next reboot is fine for a single use. But what if you need to do this several times on your computer - for example, to check equipment or connect new devices? In this case, it is better to disable Fast Startup so that an invitation to press F2 (or Del, or another key) is shown without fail.
To do this, you first need to go to the control panel. This can be done through the context menu, which is called by right-clicking on Start.
A list of settings will be displayed. In it you need to find the section with power supply. Next, you need to open the sub-item for configuring the power buttons.
Most likely, the check mark will not be available. In this case, you need to click on the special link just above so that Windows 10 will allow you to adjust the unavailable values.
Then you need to uncheck the box to put Windows 10 into normal start mode.
When acceleration is disabled, after each turning off / on the device, you can use the keys to go to the BIOS.
Some users have problems logging into bios in this system, although in most cases uefi is now used instead of bios. You can distinguish them by the presence of the first graphical interface and the ability to use the mouse. However, they perform the same functions and have similar interface tabs. Usually it is impossible to enter them because the top ten uses fast start, which is very similar to hibernation. Therefore, if the user turned off the computer in normal mode, then he will not see prompts to press certain keys to get into uefi.
Logging into UEFI from the operating system
To open this menu from the system itself, it must be launched in uefi mode, and the user must also have possibility to enter to the system, or at least to the boot screen.
If the user can freely work with the system, then he will have to go to the next item All parameters - Update and security - Recovery.
In the window that opens, it remains to find the specified button and click " Reboot now". The device will restart itself and launch a special boot menu similar to the one shown below. 
Then you have to click on the menu again. First you need to click on the item Diagnostics, and then go to the section additional parameters... In this window, it remains to find the section that is responsible for the uefi firmware and click on it. 
Thereafter the device will restart and the motherboard parameters window will open. If the user cannot get into the system itself, but has access to the login window, then he can click on the shutdown icon, after which it remains to hold down shift and click on the Reboot line. Such manipulations will allow you to go to the same recovery menu.
Standard input when turning on the computer
The first option seems too long for many, while you have to perform much more manipulations and reboot the device several times. Before, everything was easier, when loading, you had to click f2 or del and everything was ready. However, a dozen loads really quickly and users now have little time to press the desired button. Sometimes the download is so fast that you may not have time to notice the window itself, which asks you to click a button.
To be able to enter in the usual way, you need turn off mode quick start. To do this, go to the start and select there Control Panel... In the menu that opens, go to the Power supply section. Then you need to click on the item power button actions.
In the window that opens, it remains to select the line “ Parameter changes that are currently unavailable». 
This is how you can now go to bios or uefi, for this you will have to carry out a few more manipulations or refuse to quickly start the device.
The BIOS settings environment on computers with Windows 10 practically does not differ in its characteristics from the rest, because its content does not depend on the operating system, but on the motherboard, firmware, and the characteristics of the device manufacturer.
Therefore, you can try to start in the same way as on computers with other operating systems - by pressing the F10 or Esc key when starting the system. At the same time, it is necessary to seize the moment before starting the OS itself, when the device has just started to turn on.
However, now on new models of computers and laptops, manufacturers very often set fast boot. Probably, it is believed that an ordinary user does not need access to the BIOS during a normal boot, and displaying an additional screen only makes the system start slower.
Instead, in the Windows settings, it became possible to get into the BIOS menu without chaotic banging on the keys in attempts to press the desired button in time before the OS starts to boot. Below we will describe this method in more detail.
On a note! We draw your attention to the fact that this method works on any devices using Windows 10 - both on ordinary stationary computers and on laptops and tablets.
How to run a BIOS on the top ten? detailed instructions
- First of all, we open the start menu "Start". We select "Parameters". On some assemblies, this item may be called "Settings", so be guided by the gear symbol near the inscription.
- Next, in the "Settings" section, select the "Update and Security" section. This section contains key settings for updating standard programs and system management. Access to this section is possible only from the Administrator profile for this PC.
- In the "Update and Security" section, select the "Recovery" sub-item, which is responsible for system recovery. In this sub-item, in the special section "Special boot options", select the "Restart now" function.
- The computer will restart, you should wait a little. After the reboot, a special screen for additional boot settings will start. Here we select the "Diagnostics" tile.
- BIOS is an additional diagnostic tool as it is a third-party shell for Windows. Therefore, in the "Diagnostics" menu, select "Additional parameters".
- Among the additional diagnostic options, select "UEFI Firmware Options".
On a note! For reference, UEFI is a special environment that helps to start correctly and conveniently, and other elements of loading and detailed configuration of your device.
- Another UEFI Firmware Settings screen will open. You must click on the only option - "Restart". Here you can go back if you entered this item by mistake or change your mind to restart your computer right now.
- Wait for the computer to restart again, which is necessary for the boot menu functions to start correctly. Done! Here is the BIOS menu, with which you can configure the software loading on your computer, system time, change security settings and diagnose the main characteristics of the system.
Additional Information
On some computers, the UEFI Firmware Settings menu item may not appear. In this case, you need to try to enter the BIOS using the keys when the system boots.
If this method does not work either, you need to update the BIOS drivers on your computer. You can find them on the device manufacturer's website.
If the problem is still not solved, this is a reason to carry the device to the service center.
Important! Please note that you need to contact the manufacturer's service center, and not to third-party companies, since this malfunction is a marriage of the factory firmware of your computer.
That's all the information on ways to help you do it right.
Video - How to enter BIOS on Windows 10
The article will focus on the topic of BIOS on a computer running the Windows 10 operating system.
If anyone else does not know, then here is some useful information for you, so to speak, in the furnace. In simple and understandable language, the BIOS is a special program that controls the startup of the computer and the loading of the operating system. As soon as the user clicks on the power button of the computer, bios starts testing the hardware for compliance and performance, checks for the presence of mandatory connected devices (hard disk, RAM memory, video card, etc.).
Having entered the BIOS, you can configure all kinds of operating system startup parameters, view system information about the computer and hardware, select / change the system boot source (hard disk, CD \\ DVD drive, flash drive) and much more.
But there is one nuance, which we will talk about further. You can enter the BIOS by certain actions that are different for each motherboard manufacturer. For example, by repeatedly pressing the Del key while turning on the computer, but before the operating system starts to load. There are also options when you need to press the F2, Esc or F1 key.
BIOS existed before, and still exists today. Let's find out how to get into BIOS settings on Windows 10.
Computers running operating systems released after Windows 7 (windows 8-10) load the operating system in just a few seconds, during which it is impossible to press the required key and enter the bios. But this is no longer necessary: \u200b\u200byou can enter the BIOS in other ways, which we will now consider.
By the way, modern computers are equipped with an improved version of the BIOS called UEFI. Necessary steps to open BIOS on Windows 10:
Alternative way
Another way to enter BIOS when there is no access to the desktop on Windows 10, but the Logon Screen is open:
Click on the shutdown icon, press the Shift key and simultaneously select the item, after which a menu of special boot options will open, in which you will need to repeat steps 6-8.
If the operating system does not load at all, then we press the computer power button and repeatedly press the Del key (or F2, depending on the motherboard).
If you were looking for BIOS settings in pictures, then you came to the right address.
The changes made will be protected by a lithium battery built into the motherboard and maintaining the required parameters in case of voltage loss.
Thanks to the program, it is possible to establish a stable interaction of the operating system (OS) with PC devices.
Attention! The present section of the Boot network configuration allows you to adjust the parameters regarding the system boot speed, keyboard and mouse settings.
After completing work or familiarizing yourself with the Bios Setup Utility menu, press the burning Exit button, which automatically saves the changes made.
Main section - Main menu
Let's start with the MAIN section, which is used to modify the settings and adjust the timing.
Here you can independently configure the time and date of your computer, as well as configure the connected hard drives and other drives.
To reformat the hard disk operation mode, you need to select the hard disk (for example: "SATA 1", as shown in the figure).
- Type - this item indicates the type of connected hard disk;
- LBA Large Mode - is responsible for supporting drives with a volume of more than 504 MB. So the recommended value here is AUTO.
- Block (Multi-Sector Transfer) - For faster operation, we recommend choosing the AUTO mode here;
- PIO Mode - enables the hard disk to work in legacy data exchange mode. It is also best to choose AUTO here;
- DMA Mode - gives direct memory access. Select AUTO for faster read or write speeds;
- Smart monitoring - this technology, based on the analysis of the drive's operation, is able to warn of a possible disk failure in the near future;
- 32 bit Data Transfer - the option determines whether the 32-bit data exchange mode will be used by the standard IDE / SATA controller of the chipset.
Everywhere using the "ENTER" key and arrows set the Auto mode. The exception is subsection 32 Bit Transfer, which needs to be fixed with the Enabled setting.
Important! It is required to refrain from changing the "Storage Configuration" option, which is located in the "System information" section and not to allow correction "SATADetectTimeout ".
Advanced section - Additional settings
Now let's proceed to the settings of the basic PC nodes in the ADVANCED section, which consists of several sub-items.
Initially, you will need to set the necessary processor and memory parameters in the Jumper Free Configuration menu of the system configuration.
Choosing Jumper Free Configuration, you will go to the Configure System Frequency / Voltage subsection, here you can perform the following operations:
- automatic or manual overclocking of the hard drive - AI Overclocking;
- changing the clock frequency of memory modules -;
- Memory Voltage;
- manual mode of chipset voltage setting - NB Voltage
- changing port addresses (COM, LPT) - Serial and Parallel Port;
- setting controller settings - onboard Devices configuration.
Power section - PC power
The POWER item is responsible for powering the PC and contains several subsections that need the following settings:
- Suspend Mode - set the automatic mode;
- ACPI APIC - install Enabled;
- ACPI 2.0 - fix the Disabled mode.
BOOT Section - Boot Management
Here it is allowed to determine the priority drive, choosing between a flash card, floppy drive or hard drive.
If there are several hard drives, then the priority hard drive is selected in the Hard Disk sub-item.
The PC boot configuration is set in the Boot Setting subsection, which contains a menu consisting of several items:
Choosing a hard drive
The PC boot configuration is set in the Boot Setting subsection,
- Quick Boot - acceleration of OS loading;
- Logo full screen - disabling the splash screen and activating an information window containing information about the download process;
- Add On ROM - setting the order on the information screen of the modules connected to the motherboard (MT) via slots;
- Wait For ‘F1 ′ If Error - activation of the function of forced pressing "F1" at the moment of error identification by the system.
The main task of the Boot section is to determine boot devices and set the required priorities.
- ASUS EZ Flash - with this option, you have the ability to update the BIOS from such drives as: floppy disk, Flash-disk or CD.
- AI NET - using this option, you can get information about the cable connected to the network controller.
Exit Section - Exit and Save
Special attention should be paid to the EXIT item, which has 4 operating modes:
- Save Changes - save the changes made;
- Discard Changes + EXIT - leave the factory settings in effect;
- Setup Defaults - enter the default parameters;
- Discard Changes - we cancel all our actions.
These step-by-step instructions explain in detail the purpose of the main BIOS sections and how to make changes to improve the performance of your PC.
