BIOS– a set of utilities that are installed on the motherboard, which make it possible to turn on the device to install the OS. With its help, Windows 10 is loaded, a storage medium is selected, the range of thermal sensors is indicated, and various parameters are configured. If the system stops booting, errors occur and perform a recovery in a standard way It doesn't work, you can do it through the BIOS.
How to restore Windows 10 via BIOS.
But this method can only be used if there is installation disk or flash drives with a licensed distribution operating system with the version and bit depth that you have installed, without external storage this option is not possible.
First of all, you need to start by setting the BIOS to read the disk immediately when you start the computer.
If preparing automatic recovery does not make it possible to restart the computer normally, you need to do it forcibly by holding down the shutdown buttons for 10-15 seconds, as soon as the system starts to boot, you need to press one of the keys: F1, F4, F3, Delete, F8 (tell exactly which one exactly what you need to press cannot be done, as it depends on the model motherboard on your device).
You can look in the instructions for your computer or on the manufacturer’s website to find out which key you will need to log in. On most PCs, the “Delete” button is used; on laptops, the key combination “ctrl+alt+esc” can be used.
After the BIOS starts, go to the Boot section.
You need to find the “1st boot device” parameter, which can be located in the “Boot Device Configuration”, “Advanced Features”, “Boot”, “Boot Sequence” section. There you will need to set the parameter for the CDROM or PXE UND I disk to boot from a flash drive: 
Press “F10” to save the result, insert the disk into the drive or connect the flash drive on which the distribution is stored, then reboot the device.
After the computer boots, the initial system installation menu will appear, where you will need to click on the “System Restore” button.
The “Select actions” menu will open; select “Diagnostics”. 
Then go to " Extra options».
Next, click on “System Restore”. 
After clicking, a window will open asking you to select a restore point. 
Startup Repair scans your computer for errors and fixes them when they are found. You can try to run the utility, but in most cases, after searching, it usually displays a message that the computer could not be restored.
If you had a rollback provided and your Windows was successfully restored after the above steps, then after this you will need to go into the BIOS and return the hard drive boot priority back to first place.
— How to restore Windows 10 via the command line.
If you did not create a checkpoint, restore Windows systems 10 can be tried via the command line. To do this, you will also need a boot disk or flash drive with the Windows operating system installed on the computer.
In the "Advanced Options" section, select "Command Line" 
In the window that opens, type “fixboot”. 
Then the action must be confirmed by pressing the “Y” key.
After recovery Windows boot loader 10, the system needs to be checked for damaged system files.
Options for solving problems with damaged system files
- Damaged boot sector operating system.
In the command line you need to enter “fixboot”, press “Enter”, then enter “fixmbr”, press “Enter”. After this, the windows boot sector will be restored. The computer can be restarted normally. - gone missing boot file boot.ini.
In the line you need to type “bootcfg /rebuild”, then press “Enter”. Confirm all possible system questions by pressing the “Y” and “Enter” keys. - The config in the system32 folder is damaged.
You need to insert the disk with your OS version into the drive, enter “cd repair copy SYSTEM C:\windows\system32\config” in the command line, and then press “Enter”. - The files “ntldr” or “ntdetect.com” are missing, the system displays the message: “NTLDR is missing when loading Windows.”
- Enter “copy X:\i386\ntldr C:\” in the command line, press “Enter” (Where X is the letter of your drive, and C is the letter of your system disk, on which your OS is installed).
Restoring the system via the command line while the computer is on.
If you do not want to restart your computer, you can restore the system via the command line from Windows. To do this, you will need to insert the disc into the DVD-ROM while the PC is loaded. Then launch the command line by pressing the hotkey combination “Win + R” and in the search bar of the “Run” window, enter “sfc /scannow” and click “OK”. After which the broken system distributions will be copied from boot disk automatically. System recovery and rollback are quite quick and trouble-free.
If Windows stops loading, you can use standard utilities to restore correct operation.
One of the main nightmares of computer lovers is to encounter a situation where they cannot turn on the device. The operating system starts to load, but eventually displays a message like: “Failed to configure Windows updates, changes are being undone, do not turn off the computer.” After which nothing new happens - the software cannot be restored, and downloading stubbornly does not help.

System recovery tools
Before the release of Windows 7, this situation turned into numerous dances with a tambourine, and often even complete reinstallation operating system. Now everything is different, and often the problem is solved standard means from Microsoft, which do not even need to be specially installed. The task comes down to being aware, in principle, that such a toolkit exists, as well as simply remembering it when suddenly the “irreparable” happens.
The trick is that when you boot your computer, before the icons appear Windows boot, have time to get into the advanced parameters of this very boot, where you will be able to run diagnostics and, if necessary, restore the system to the selected checkpoint. In Windows 7, when loading, you had to press function key F8, then select the “Troubleshoot” option (although in rare cases the “Last Known Known Configuration” option saved the day).
More Windows 7 download options
Once in the “System Recovery Options” menu, in most cases one of the first two options became salvation. “Startup recovery” could save the operating system in automatic mode, and “System Restore” required you to manually select a checkpoint to which to rollback.
Windows 7 System Recovery Options
In order to be able to restore it to its original state in the event of a malfunction of the operating system, it is necessary to make a recovery disk in advance.
Microsoft would be betraying itself if, with the update of its brainchild, it left all the useful tools as before. Windows 10 system recovery is carried out by pressing hot keys Shift+F8, and, unlike “seven,” you need to press this combination very, very quickly, since the operating system itself began to load much faster.
Has undergone changes and appearance saving menu. Having selected “Diagnostics”, in “Advanced options” there are already familiar to us “System Restore” and “Startup Repair” (only in a different order). There is also a “Return to previous build” option if you upgraded to “ten” from one of the previous versions of Windows.
If automatic recovery doesn't work
Restoring a Windows system to one of the previous checkpoints is not a difficult task. It is only important that these points themselves exist in the system, because sometimes users themselves manually disable their creation, at the same time deleting existing ones. It really makes sense to periodically clear old control points, since they take up a lot of space. But giving up recovery points altogether is a risky endeavor.
How to navigate the Internet without picking up viruses? Secure DNS servers will help.
To make sure that restore points are automatically created for you or to make changes to the corresponding settings, you need to select the “Large Icons” (or Small Icons, but not Categories) icon display in the “Options” window and select the “Recovery” item. There, select “System recovery settings”, check whether protection is enabled and, if necessary, use the “Configure” button. Here you can manually create a point for subsequent recovery.
If we have recovery points, then using the method described earlier, that is, using the built-in Windows tools To restore the system, you can quickly roll back to an earlier state of the computer without losing important files.
In extreme cases, you will have to restore the system to its original state or to a previously created system image. It is advisable to create a “System Image” and a “System Repair Disk” in a working state of the operating system, after you have installed all the applications you need. This is all done through the same “Control Panel” (aka “Settings”), when viewing by “Categories”, selecting “Backup and Restore (Windows 7)”. Here you can restore the operating system to a previously created image if the computer still boots, but has no longer worked as it should.
With every operating system release Microsoft company requests more and more information from users. But you can moderate her appetites.
Restoring a laptop to factory settings
If standard tools do not help, and you do not have a disk or USB device with a recovery image, then laptop owners can use “hot keys” to launch the built-in recovery utility. Some models may even have a separate key for these purposes, for example, OneKey Recovery from Lenovo, but this is rather an exception. In other cases, it is important to know which “ hotkey” for your laptop, since it tends to differ among manufacturers.
Hotkeys for laptop manufacturers:
- F3– MSI;
- F4– Samsung;
- F8– Fujitsu Siemens;
- F8- Toshiba;
- F9- ASUS;
- F10- Sony VAIO;
- F10- Packard Bell;
- F11- HP Pavilion;
- F11- LG;
- F11- Lenovo ThinkPad;
- Alt+F10- Acer (before this, select Disk-to-Disk (D2D) in the BIOS);
- Ctrl+F11- Dell Inspiron;
- Hold [ Alt] - Rover.
Factory Utility will restore the device to its original condition, as if it had just come from the store. This will delete all programs with settings, all files, including favorite photos, which it makes sense to store in just such cases. cloud services. However, the device will be able to work again, and in some cases this method will simply help prepare the laptop for subsequent resale or transfer to relatives.
The Windows operating system is a very complex complex software. That is why various failures often occur in it, which, in turn, can lead to the impossibility of using the computer for its intended purpose. If this happens, then we say “Windows crashed.” In this article we will talk about the reasons for the OS not working and how to eliminate them.
There are quite a lot of reasons leading to the loss of Windows functionality. It can be software errors, for example, incorrect installed updates OS or device drivers, the actions of viruses or the users themselves. In addition to software problems, there are also hardware problems - problems with the system hard drive and RAM, depletion of the resource of the CMOS power element on the motherboard, or simply batteries.
First of all, we need to make sure that the hardware is not to blame for our problems - disks, RAM and batteries. Let's start with them.
Reason 1: CMOS battery
CMOS, which is a special chip, can be called a storage of BIOS settings. Information about the installed equipment and its parameters is recorded in its memory. The chip requires constant autonomous power to operate, otherwise all data is simply deleted. The system takes some time to read what is contained in the CMOS, which can occur with errors if the battery is dead. In order to eliminate this factor, it is necessary to replace the power element.
Reason 2: Hard drive
The system disk is a drive or partition on which all the files of the operating system “lie”. If problems arise with the disk, for example, bad sectors, both downloading and subsequent operation may become impossible. In such cases, it is necessary to check the “hard” special programs. If it turns out that there are errors on it, you will have to purchase new disk and install the OS on it. Since our Windows does not work, the actions described in the articles below must be performed on another computer.
It would be a good idea to check the reliability of the connection of the cables to the connectors of the drive and the motherboard. There is a possibility of failure of the connection ports and connectors on the SATA cables and the power supply. The solution is simple: connect the drive to an adjacent SATA port, use a different connector on the power cable, and also replace the data cable.
Another reason related to the hard drive is a failure in BIOS settings. This could be either an incorrectly set boot priority (it can go wrong if the battery is dead, as we discussed above), or an inappropriate operating mode of the SATA controller. To solve this problem you will have to go into the BIOS and change the necessary parameters.
Reason 3: RAM
When the system boots, all necessary data is first written to RAM. It is extremely rare, but still problems occur directly in the RAM modules, which leads to errors in reading and writing information. In order to make sure that the strips are in good condition, you need to use specialized software. Faulty modules must be replaced or removed from the system.
After we have verified that the system disk is working properly, random access memory and changed the battery, you can move on to identifying software causes.
Reason 4: Updates and drivers
In this article, we will not describe how it is incorrect installed drivers and updates affect the performance of the system. Suffice it to say that in such situations, only deleting problematic files or restoring the OS in various ways will help.
If a BSOD occurs when you try to boot ( blue screen death), then we can accurately determine the cause of the problem and find out which driver or other system file caused the inability to Windows startup. In this case, BSOD becomes our assistant in diagnosing and solving problems.
Reason 5: Pirated build of Windows
Unlicensed builds of Windows downloaded from torrents or other resources that distribute pirated distributions have one unpleasant feature. Installed from this Windows image may not respond adequately to changes in file system or parameters and settings. Most often this happens when installing OS updates, less often when installing drivers or other software.
There are two ways out here. The first involves recovery (see reason 4) with subsequent disabling of automatic system updates, as well as the exclusion from use of programs and “firewood”, after installation of which failures are observed. The second and most obvious is the use of licensed Windows distributions.
Reason 6: Viruses
Malicious programs can significantly complicate the user's life, including making it impossible to start the system. Fighting viruses when Windows is not working is not an easy task, but nothing is impossible. The main thing here is to determine the sequence of actions when such a situation arises. There are two scenario options.
- We first restore the system using the methods described in the paragraph describing reason 4. Then, from a running Windows, we identify and remove pests using anti-virus utilities.
- The second option is to clean the system from viruses using a boot disk, for example, and only then try to start Windows or perform a recovery procedure in case of failure.
Which script to use is up to you. Let us only note that in the first case, restoration using standard means (recovery utility) may not lead to the desired result. The reasons for failure are malware, which place their files in the user’s folders, and during a rollback these elements are not subject to change. For such viruses, the second option is suitable.
To ensure that such problems occur as rarely as possible, protect your PC from pests. Antivirus software and discipline will help with this.
Conclusion
In this article, we examined the most common reasons for “Window crashes” and tried to give the most universal methods their elimination. Typically, system recovery helps in such situations, since software is most often to blame for failures. Do not forget about the “iron” factors. Be aware that connectors may come loose even when the cover is closed. system unit due to shaking or shock when moving. The same goes for hard drive– it can fail as a result of mechanical impact. With unlicensed Windows, everything is simple: try not to use such distributions, and as for viruses, read the articles on them on our website, the links are above.
Developers from Microsoft Corporation offer several methods to return Windows 10 to its original state, thus saving the user from reinstalling the operating system with subsequent installation of software, device drivers and personalization. There are several ways to return your computer to working condition:
- using system restore from a checkpoint;
- returning the OS to the position it was at the time the system disk image was created with all configuration and user data;
- through USB usage or Windows Resume DVD.
In this article we will analyze in detail each method of recovery. the initial state Windows 10 and we will give brief but clear instructions to roll back the OS to its original position.
Using Operating System Resume Points
Before you return Windows 10 to one of its previous states, you need to make sure that the function of creating shadow copies of the operating system is activated, which will help revive it in case of serious problems. To check and enable the option responsible for creating restore points in certain situations, the “Control Panel” item of the same name is responsible.
- Go to it and select “Recovery” or write the phrase in the search bar.
- We launch the application, which is usually first in the list.
- Click on the last option “Recovery settings...”
If installed licensed Windows 10 on your computer or you are using an assembly whose author has not deactivated the function that allows you to return the OS to its original state, then automatic creation of checkpoints is enabled.
After selecting the drive (often drive C is the system drive), it also stores the files responsible for the initial state, and clicking on the “Create” button, Windows will create a checkpoint. It can be used to return a previous copy of the operating system. The “Configure” button will allow you to specify the size of data recovery points allocated for storage or disable the option of recording the OS state to the computer.
In addition to manual creation, rollback points are created when major changes are made to Windows: installing/uninstalling programs and drivers or editing system parameters.
- To restore the original position of the “tens”, click “Restore...”.
- In the next dialog, simply click “Enter”.
- Select the previous system state and click “Next”.
- Click “Finish” or “Enter”.
- In the dialog warning about the impossibility of canceling or interrupting the operation after starting, we agree to the proposed conditions.
- We are waiting for the completion of the preparatory process.
- After waiting a short time for the computer to roll back, close the next window and restart Windows 10.
System Resume USB Disk
If in all previous Windows 10 operating systems the recovery disk contained only tools for automatic/manual recovery of the OS installed on the computer, then in the latest edition such media can store an image from which the OS can be returned to its previous state.
- Go to the “Control Panel” and call up a tool called “Recovery”.
- Click on the first link: “Create a recovery disk.”
- Check the option shown below and click “Next”.
This action will allow you to instantly reinstall Windows.
- Select a USB drive.
- Close the window after the message about the successful completion of the operation appears.
- We start the computer from the created flash drive by calling the boot menu after initializing the hardware with the BIOS.
- Go to the “Diagnostics” section, then to “Advanced settings”.
- Click on “System Image Restore” and select your own account.
- If necessary, enter your account password.
- Select the previous system state, which is stored on the HDD, and click “Next”.
- In the last dialog, click “Finish” and wait for the operation to complete.
Creating a system image
This section provides an excellent solution to the problem of reinstalling the OS. It consists of the following: we install the OS, configure it, install device drivers and application software, then save this state into an image file on the computer for subsequent restoration of the operating system. It's better to do this after fine tuning reinstalled Windows 10.
- To do this, go to the “Control Panel” item called “File History”.
- We enable file history by clicking on the button of the same name.
- Call up the dialog for manually creating a snapshot of the system and boot disks.
- Specify the path to store the image.
- After clicking on “Archive”, the process of creating a backup copy of the system and reserved by the system volumes.
- Then we just wait for the end of the reservation.
In "Advanced settings" you can set the frequency of automatic backups and the duration of their retention period.
Rollback to previous state
The last method to return your computer to its previous state using the tools integrated into Windows 10 is to use the hard reset feature.
- Open the “Settings” window and click on the “Update and Security” item.
- Move to the “Recovery” tab and click “Start”.
- We choose the first option for Windows reinstallation 10 with saving all installed applications and settings.
- We are waiting for the end of the preparatory stage.
- In the window with a list of applications that will be lost when the operation of returning Windows to its original state is completed, click “Next”.
- We get acquainted with the proposed information and click “Reset” to return Windows to its original state after a reboot.
- We are waiting for the system to do the work assigned to it.
- Then it will start almost automatically Windows installation 10.
After setup, the computer is ready for use. This method will help out in moments when there is no bootable flash drive with Windows 10 and the opportunity to get it.
Operating system backup using Acronis
Here we will briefly look at how to roll back Windows 10 to its original state using Windows image 10 created in True Image.
- Download the application, install and launch it.
- We choose to launch a trial edition.
- Click on the second button on the toolbar called “ Backup».
- Select the option to create a new copy.
- Select a source.
- Specify the system and reserved volumes as the backup source.
- Specify the path to save the backup copy and click “OK”.
- Click “Create Now”.
- Once the process is complete, exit the application.
- If you need to restore Windows 10 from the created file, go to the “Backup” section, where you select the required backup.
- Mark the partition to be restored from a copy and click “Restore now”.
- We agree with the requirement and reboot the PC.
After this, the data recovery process will start, upon completion of which the computer will boot with the selected copy of the operating system. It is better to perform the proposed actions by loading the program from a flash drive, and not from under the operating system.

As in any OS latest generation, Windows 10 has the ability to resume information in case of critical errors. This can be done using the following methods: rolling back changes, using an image with a backup copy. Which method is most effective and how to do it Windows recovery 10 as fast as possible? Let's try to figure it out.
Few users know all the ways to restore the OS
Most often we are talking about a regular flash drive. On such a disk previous versions The systems were only programs, using which one could try to restore an incorrectly working system. In this variation, the disk may contain the OS image itself. This means that by using this tool, you can launch a rollback by reinstalling Windows without user intervention.
To burn the drive, use a flash drive, select “Recovery” in the control panel. Click on “Create a recovery disk”.
When creating a flash drive, you can copy system files to it. The created drive can also be used to quickly reinstall the OS on the “machine”.
If problems arise with the operation of the system, use the rollback disk (they will help boot menu or change of priority). The menu will have a “Diagnostics” section, which consists of sub-items:
- run on boot automatic recovery;
- restore the system from an image;
- return the PC to its original state using the files on the drive;
- go to the command line;
- go to BIOS;
- restore the system using a rollback point.
Armed with such a flash drive, you can solve any problem with your computer, spending a minimum of time. Experts praise this method and recommend it if other manipulations have not helped the matter.
The easiest way
To understand how to restore Windows 10, you should first explore this option. Just click on the notifications icon, and then get to the “All settings” item. Now you need to go to “Update and Security”, “Recovery”. If the OS does not start, then the procedure must be performed using a recovery drive (this option is described above).
Go to “Restore to original state”, here you will be offered to reinstall the system, save personal files or completely clean the PC. If you choose option #1, Windows will use the files that are already on your computer, so you won't need a drive. By choosing option No. 2, you will be able to save videos, photos, etc., but settings and utilities installed manually after installing the OS will be lost.
Windows also offers this rollback method - you need to press the power key before entering Windows, and then click on “Restart” while holding down “Shift”. As you can see, there is no need to log in. A new scenario will appear, where after going to the “Diagnostics” section you can return to working version BY.
The OS reviewed here is the newest one, and manufacturers are just starting to release devices with pre-installed Windows 10, but most likely, when you roll back in this way, the developer utilities and drivers will be reinstalled automatically.
Advantages: there is no need to search for a distribution; in addition, automatic reinstallation reduces the risk of errors by inexperienced users.
Flaws: if files are critically damaged or the hard drive is damaged, resume Windows operation it won't work. If the method does not help, use image or drive.
Restore point
Such points will help you roll back to the desired date, when there have not yet been any problems with the system.
The points contain data on problematic operating systems system files, which have changed due to user actions (installing a program, changing settings, etc.), but they do not contain a complete image.
First, it is important to study the settings. After going to “Recovery” you need to find the “Settings” option. You can get here faster by opening the command line (Win+R) and typing systempropertiesprotection.
Rollback points are formed for partitions with protection enabled. There is information about this in the parameters; the option to create points can be enabled. There you can also specify the size that will be allocated for rollback points. Old points will be “overwritten” automatically as the space is filled.
Creating a point
Click on the “Create” item in the “System Protection” section (Start - System). Now set a name for the point to navigate the list and confirm your decision.
You can use the point in different ways - you can use diagnostic tools, the system interface or the command line.
The elementary method is to go to “Run recovery” in the “Recovery” section. It is advisable to select the point required by date and begin the procedure.
An alternative method is to start with command line. It will help if you can log into Windows only using safe mode with DOS line support. Here you should enter rstrui.exe and press the enter button. Again you will need to select a specific item and click on start.
There is a third option, the path looks like this: Settings - Update and Recovery.
System image: how to use it
- you need to go to “ Backup copy image" section "File history";
- further, “Creating an image”;
- then select the folder where the image will be stored and the partitions that will be added to it.
A rollback from the image is done using a special drive. You can also select the “Image recovery” tab (it is located in the “Advanced options” item in the diagnostics section).
