Windows 7 error recovery. Windows system recovery

Often there are cases when, after installing a program, driver, accidentally deleting a system file, or a virus attack, the Windows 7 operating system starts to “slow down” or stops functioning altogether. If there is no important information on the computer, then it can simply be reinstalled. Otherwise, System Restore will help you. This tool returns the OS with all the data on the hard drive to a healthy state.

Windows 7 system recovery methods

The developers of the Windows OS provide a number of standard recovery methods, but all of them do not give a 100% guarantee. Therefore, be prepared that you may need to use several methods of resuscitation in turn.

You can restore the health of Windows 7 using:

apply the last working configuration;
safe mode;
restore points.

Using Last Known Good Configuration

This Windows recovery tool is the easiest to perform, so you should resort to it first. The sequence of work will be as follows:

After performing the above steps, data from the OS registry and working parameters of existing drivers are automatically restored. If this method fails to start the system, go to the second method.

Safe Mode is an effective Windows resuscitation tool

Safe mode is a special version of the operation of operating systems, which does not automatically start installed programs, as during a normal Windows boot. In this case, only those drivers are activated, without which the operation of the OS is impossible.

This tool is launched in the same way as the last working configuration, that is, using the F8 key. When you log in using this method, the screen resolution will change to 800x600. This is normal, so no need to worry.

The following recovery order is shown below:

The boot disk with Windows 7 is inserted into the DVD drive and starts up. The build of the system you use must be the same as the one on your computer. Therefore, if possible, take the same disk that you used when installing the operating system.
When a pop-up message about autorun, click "Cancel".
Open the command window "Run", which is located in the "Start" menu.
We enter the command to check the health of system files "sfc / scannow".
Some time after the activation of the process of searching for executable files, all damaged or deleted system data will be copied from the DVD and restored.
If you want to monitor the progress of the recovery, you need to enter the command line by typing "cmd" in the "Run" window. After that, “sfc /?” is written in the line. You must log in to the command prompt as an administrator, otherwise you will not receive the required information.
If on the command line the data will be displayed in the form of hieroglyphs, then you will additionally need to enter the properties and select the required language there.

Using a restore point

Another effective tool for resuscitating a Windows system is the use of restore points. The principle of operation of this function is based on the fact that after a certain period of time the existing OS configuration is written to the hard disk. If you encounter any software problems, you can use the saved points and restore the computer to working order.

What is the reason for the refusal to start Windows 7 on the computer? The following factors may affect the possibility of issuing an error when starting Windows: computer infection with viruses, hardware configuration failure, software installation errors, operating system imperfections.

It is required to find the true reason for their issuance, for this it is necessary first of all to figure out what stages the download of Windows 7 consists of. It consists of 3 main stages, which in turn are divided into stages:

Windows 7 boot stages

First stage - OSLoader

Immediately after the execution of the "BIOS" code, the first stage of loading begins. Here, at the first stage, the main drivers are connected, which are required to read data from the hard drive. After that, “winload.exe” starts loading the kernel, loads the “SYSTEM” registry hive into RAM, as well as the “BOOT_START” program.

The duration of the first stage is no more than three seconds. It ends when the Windows 7 logo is displayed on the monitor.

Second stage - MainPathBoot

MainPathBoot is the main and longest stage. The duration sometimes reaches several minutes. The phase begins with the Windows 7 logo displayed on the monitor and ends when the desktop starts to launch.

Stage PreSMSS

The kernel of the operating system is determined, “plug and play” is loaded, the “BOOT_START” programs and drivers of computer components are determined. If errors appear, this indicates a problem with the computer components.

SMSSInit stage

Next, control passes to SMSS.exe. The remaining registry hives are determined, included in the work of the program of the “auto” type. At the final stage, Winlogon.exe, the operating system logon utility, takes control. "SMSSInit" is completed when the menu with the username and password is displayed on the monitor.

Here, errors indicate a malfunction of the video card or its drivers.

WinLogonInit Stage

It starts with the launch of "Winlogon.exe" and ends with the appearance of the desktop by loading "Explorer.exe". Includes group policy scripting and service loading. This is the most CPU-intensive step and usually takes a long time.

Here, errors indicate problems with the services of programs not included in Windows, for example, antivirus software.

ExplorerInit Stage

Continues from loading the shell and ending with loading the window manager. During the stage, shortcuts begin to appear, in parallel, the programs that are in autoload are loaded. This stage is characterized by the largest load on the processor, hard drive and RAM.

Here, errors indicate defects in components or the need to upgrade them.

Third stage - PostBoot

It lasts from the moment the desktop is displayed and ends with the full opening of programs from startup.

Errors indicate problems with applications that appear in the startup list or the presence of infected files on the computer.

Errors that occur during the startup phases

By examining what errors occur at various stages of system startup, it is possible to identify specific problems.

Errors due to defects in computer components:

Repeated errors of any driver indicate a hardware defect associated with this program;
Multiple problems at various stages indicate a defect in the RAM;
If there is no image on the computer monitor, but Windows sounds are present, then this indicates incorrect operation of the video device;
If it is impossible to start starting Windows or interrupting it, you should check the health of the hard drive;
If a complete shutdown occurs at startup, then the power supply or motherboard may have failed.

Missing or broken boot files

The display on the monitor "Bootmgr is missing" indicates the absence or malfunction of boot files, and sometimes just a blank black screen happens.

If the bootloader "Bootmgr" is not installed on the computer, the system will not boot. This section is sometimes accidentally erased by the user himself, using a boot disk.

Also, the necessary files to start the system are located on the C: drive in the Windows folder.

Registry problems

Windows can sometimes restore it on its own using the recovery wizard.

Restarting the operating system

Recovery environment

Windows 7 has "Windows Recovery Tools WRT". To restore, you need to select from the F8 menu "Troubleshoot your computer."

Next, the "System Recovery Options" menu will appear - you need to select "Startup Repair".

This will restore the startup options and files.

Recovery Methods

In the case of a software type of error, System Restore will help the OS.

Manual recovery

If there is no positive result after using the system tools, it is possible to manually restore the registry from a backup copy, which is located on C: in the WindowsSystem32configregback directory. You need to copy the files from it to the WindowsSystem32config directory.

File recovery

There is a useful program "sfc.exe" that can be run in the recovery environment. You must specify the following: settings and location of the download folder and offline directory of the system Windows directory). The /offbootdir and /offwindir options.

If the startup problems are not resolved, then you need to manually restore the boot files.

Often, users of computers running Windows 7 encounter operating system health problems. Computer problems usually appear when it slows down and programs do not open. Also, the computer may not start at all or do it every other time.

The reasons that cause problems in the performance of the operating system can be very different. For example, if a computer gets virus, it can damage system files. Also, difficulties with the PC may appear during installation. low-quality software, which can damage the structure of system files. To solve the problem with the health of a computer on Windows 7, you need to roll back to the previous restore point.

To protect the OS in Windows 7, restore points are used that the system periodically creates. Essentially, restore points are previous state of Windows 7 system files. To help the Windows 7 PC user, we have prepared a material that will describe the detailed system recovery process in various ways.

Recovery in the loaded seven

If your computer running Windows 7 boots, but the system is not stable, then it's time to roll back to a previous restore point. First of all, we need to get into the window in which you can call up the system recovery options. To do this, open the program "" by pressing the key combinations Win + R, through which we enter the following command: systempropertiesprotection

A window should open before us. Properties of the system» tab « System protection". You can also get to this window in the standard way through the menu " Start". The next step is to press the button Recovery….

After clicking, the System Restore window will open. It will prompt you to restore the system using the recommended access point or choose another one. We will stop at recommended restore point.

This window requires confirmation for the selected restore. To confirm, press the button Done.

This button will bring up a message warning that after the restore procedure it will be impossible to return to the previous parameters of the seven. By clicking on the Yes message, we will start the Windows 7 system restore.

If the process of returning to the previous state occurred without errors, then a corresponding message will be displayed.

If you are unable to roll back to the previous settings using the recommended point, then you should select the point that was created later than the selected restore point Windows 7 systems. I would also like to note that to perform this operation, you will need special privileges. That is, when you log in, you must select an account admin and enter a password for it.

We return the computer to working capacity at OS startup

In case your PC is running seven at all is not downloading, then you can start the operating system in safe mode. After the BIOS start window appears, press F8 on the keyboard (for laptops there may be another key, for example, Del or one of the function keys). This action will cause menu of alternatives loading sevens.

In this menu, select the item " Safe mode”And continue by pressing Enter, after which the system will start in safe mode.

If the system has successfully started in safe mode, then start the recovery of the seven, as shown in the previous example. In this mode, for maximum security many features disabled OS, including the Windows Aero graphical interface. This is how the running program "" with the command " system properties protection” on a system running in safe mode.

We return the computer to working capacity using the installation disk or bootable USB flash drive

If the two previous examples do not help you, then you will need to restore the seven installation disk or flash drive. For computers that do not have an optical drive, you need to use a bootable USB flash drive with the OS. A bootable USB flash drive can be created using special utilities. The most popular utilities for this purpose are Windows USB/DVD, Download Tool And Rufus.

Boot from the installation disk or via a USB flash drive. In the start window of the installer, click the Next button and proceed to the next window.

After searching, select the OS you want to restore and click Next.

In the window that appears, select the same item " System Restore».

This action will launch the seven recovery utility. In the utility, click the Next button. This action will take you to restore point list. We choose a suitable point and continue.

A window will appear in front of you, as in the first example. Therefore, we press the Finish button and respond to the message, after which we will start the recovery.

After a successful rollback to the previous state, you will receive the following message.

Windows 7 Disaster Recovery with Antivirus

If your PC is infected viruses that interfere with the correct operation of the computer and the first three examples considered do not help you, then a good way to restore in this case would be an anti-virus life disk from Dr.Web. With this disc you can clean the system from all kinds of dangerous software. In addition to cleaning, Dr.Web LiveDisk can disinfect infected objects, which are necessary to restore Windows 7.

The Dr.Web LiveDisk image can be used both for recording onto an optical disc and a flash drive. To use Dr.Web LiveDisk on a USB drive, you need a special program. You can download the program for writing to a USB flash drive and the image itself on the official website by going to the page www.freedrweb.ru/livedisk.

Let's start the recorded image on the disk, setting it in the BIOS as the first boot.

In the start window of the bootloader, select first item Dr.Web LiveDisk and press Enter. These actions will start downloading Dr.Web LiveDisk.

After downloading Dr.Web LiveDisk, we will get a full Linux-based operating system. As it was written earlier, the main purpose of Dr.Web LiveDisk is to clean and cure of virus software. Therefore, antivirus is built into this OS. Dr.Web CureIt!. This antivirus is launched along with the OS.

Let's click in Dr.Web CureIt! button Start scan, which will start scanning, cleaning the system and disinfecting viruses.

After verification, Dr.Web CureIt! delete or disinfect infected objects.

Since there will be no more malicious code in the system, you can safely restore the system in three ways, which are described above.

If after checking the system files you cannot restore the Windows 7 system, then the only reasonable solution is to make a full backup of the information and reinstall the system again.

How to make a system image in seven

Another recovery feature in Windows 7 is creating a system image. In this image, you can save all the information on the hard drive, including the operating system. By restoring in this way, you will receive an OS with the same parameters as on the day the image was created.

Run " Control Panel' and go to the tabs ' system and safety», «»

In the window that opens for creating an image, specify the location to save it and click Next.

In the window that appears, it remains only to click the button Archive, which will start the process of creating an image.

You can restore the created image with Windows 7 and all information on local drives using the installation disc. The principle of recovery is shown in the second example, only when choosing a recovery method, you need to select " Restoring a system image” and specify its location on the saved drive.

Alternative methods for restoring the Windows 7 operating system

In addition to the standard recovery methods, there is an alternative software that does the same function. The most interesting solution that allows you to restore the system is the program Acronis True Image 2016. This is a proprietary software package from Acronis.

First of all, let's download and launch Acronis True Image 2016 from the shortcut on the Desktop. When launched, the program will ask for a username and password.

Now let's set up Acronis True Image 2016 so that he can do full disk backup with Windows 7. This setting should be done immediately after installing the OS, so that while using Windows, you can restore functionality from several backup copies of the system created in a certain period of time. So let's get started with the setup. To do this, select the type of storage by clicking on the link "".

In the window that opens, select the storage " Acronis Cloud».

Now let's create a schedule for our backups. To do this, press the button " Parameters” and go to the storage settings settings. On the first tab, select the schedule you like for creating backups of our system.

As you can see, the entire computer is selected as the backup source. Therefore, in the schedule set by us, a backup copy of the system will be created in the cloud storage " Acronis Cloud».

For an example of recovery, let's take an archive copy not from the Acronis Cloud cloud storage, but from the hard drive. If a backup was created on the computer, then Acronis True Image 2016 he will find her.

So we press the button Repair your computer, after which the program will completely restore the system to the state that it was when the backup was created. Also, if you are unable to start Windows 7 on a computer, Acronis True Image 2016 there is a boot image for this that can be burned to disk.

You can download this image on your account page. You can get a password and login on the official website www.acronis.com. The principle of the bootloader is the same as with the desktop version. Load disc from Acronis True Image 2016 on the computer, you can set it in the BIOS first when booting.

From the example it turns out that the utility allows full control over the creation of PC recovery copies and back up your entire system to the cloud.

Acronis True Image 2016 boot disk example

To start a disc Acronis True Image 2016 when starting the system, you must set the boot mode from the optical drive to the first in the BIOS. For example, for the MSI A58M-E33 motherboard, these parameters in BIOS mode look like this.

Another way to boot is to use hotkeys to call up the BIOS boot drive menu. For example, for the MSI A58M-E33 motherboard, the hotkey is the F11 button. By pressing this button, we will launch a special mode in which, when the system starts up, drive boot menu in BIOS.

After booting from the Acronis True Image 2016 disk, we will get to such a menu.

In this menu, select Acronis True Image 2016, after selection, the program will start.

The example shows that starting the boot disk Acronis True Image 2016 using the desired BIOS mode is not at all complicated.

Summing up

In this article, we have analyzed almost all the methods and parameters system recovery. We also looked at ways to restore the seven with alternative software and with the help of an antivirus. Which way to choose to restore Windows 7 depending on the situation is up to you.

Summing up, I would like to note that they mainly disrupt the operation of the OS viruses and experiments with different illegal software. Therefore, so that you do not have to constantly restore the system, use only proven and licensed software, and also use reliable comprehensive anti-virus protection.

I would also like to note that the examples considered in the material will work not only on Windows 7, but also on more modern operating systems, such as Windows 8 And 10 . And we, in turn, hope that our material will allow you to properly restore Windows 7 and you can say with confidence that I can do system restore.

Solution to the problem

In the case when all the initial stages of launching Windows 7 on a PC or laptop are performed normally, but windows 7 still does not start up to the end, then this usually confuses novice users. Although in the presence of detailed instructions, the question: "What to do?" will not appear even for beginners. If the cause of the problem is a hardware failure, then it will be indicated by the signal from the speaker of the laptop or desktop computer during the POST test. If so, then the OS will not start.

But if the problem is of a software nature and the process stops at the stage of loading Windows 7, then the user has encountered the most common problem that can be solved using the algorithm of typical actions.

Instructions for action

You must use the OS recovery tool. During the PC startup process, if windows 7 does not start, the system often recommends the owner of the computer or laptop to select boot options. If for some reason such an offer was not received, then the user can independently open this menu by clicking on the “F8” button. Then proceed to restore the normal download of the "Seven".

What to do if the above instruction did not cope with the problem?

To fix the problem when windows 7 does not start, you need to use the OS CD:

Install the installation disk in the PC drive;
Start the system from a disk (in the BIOS, the corresponding order of loading the system from media should be set);
In the window that appears, click on "Apply recovery features that fix problems with booting the OS" and click on "Next";
Then, in the "OS Recovery Options" menu, click on "Startup Repair";
Wait until the analysis of the system is completed and the causes of failures are eliminated;
Restart your PC;
In the BIOS, set the system to start from the hard disk ( when exiting the BIOS, be sure to save the changes made);
Restart your computer again;
Ready! Now Windows 7 will boot normally.

Using the command line

If for some reason it was not possible to restore Windows using the installation disk, then there is another way to do this through the command line.

First you need to take the steps indicated in the paragraph on restoring the normal download of the Seven. The only changes are that just in the "System Recovery Options" menu, you now need to specify the section - "Command Prompt".

What to do when it was not possible to achieve a positive result by following the above instructions?

If success was not achieved and the user has already reached this part of the article, then the problem cannot be categorized as typical failures of the OS boot distribution. You will need to do all further actions in Windows safe mode. It is recommended to analyze the "C" drive for the appearance of broken clusters.

To enter "safe mode" you must do the following:

Why are preventive measures important?

Windows 7 provides a special system that can make special reference points, with the help of which, if necessary, it is restored. By applying this protection function, even a novice user can always easily return the OS to a working state.

For example, in case of failures due to incorrect installation of applications, drivers and other utilities such as codecs, or when errors appear due to adjustments to the registry.

It should be noted that in the "Seven" it is possible to allocate a fixed amount of memory on the hard drive specifically for such protection of the operating system. In Windows 7, self-configuration of protection is available along with system data as well as files, or you can do it separately.

Due to the presence of viruses, inconsistencies in drivers or software, the OS may fail. If your Windows crashes, don't panic. The situation can be corrected by returning the state of files and programs to the moment when the PC was working properly.

While running OS Windows 7, 10 or 8, certain errors and problems may occur. As a result of such failures, a new launch of the operating system in operating mode becomes impossible. In this case, it is not at all necessary to do a laborious reinstallation of the OS. It is enough to perform a system restore.

OS recovery using the recovery environment

At work, we use the following scheme of actions:

Reboot the computer, press the F8 key during boot;
Troubleshooting;
System restore, OS restore point selection;
click "Further" and again "Further";
We press the button "Ready", reboot the system (in the Menu, select boot with the last known good configuration).

Windows 7 System Restore

There are several ways that you can resort to resuming the operation of the OS. Some of them are based on reverting to saved settings. Others simply clear the data.

You can perform "resuscitation" of the OS in one of the following ways:

by selecting restore points;
using the command line;
through safe mode;
using the recovery environment;
using an image/boot disk.

Restoring the operating system using system "resuscitation" checkpoints is one of the most affordable, effective and popular options. To apply it, you need to make a series of clicks:

Panel "Start";
"System Restore";
"Further";
"Select a restore point";
"Ready".

This operation will fix the problems with the computer, undo the changes and return the system to a working state that allowed the PC to boot normally. Loss of data, files and documents does not occur during such recovery. All data is saved. The operation is reversible. You can roll back the system to a previous state of the computer and use a different restore point.

Many people ask themselves how to make a recovery point on their own (manually) in order to choose it in the future? To do this, in the same menu "Start" - "System Restore" You can create such a point yourself at any convenient and suitable time for you. It will be saved with the current date, which can only be remembered.

From a restore point

In computer engineering, there is such a thing as a restore point. These are saved PC settings. As a rule, saving occurs automatically with each successful OS boot. The easiest way to resume Windows 7 is to use exactly this data.

Press F8 when the computer boots up. This command will bring up a menu of system startup options. Next, select the Last Known Good Configuration option.

You can also use another method. Enter the properties of the My Computer folder. Find the System protection line, clicking on which you will open the dialog box of the same name. Click Recovery - Next. We set a key date, indicate the disks that are subject to correction, and confirm the actions. After rebooting, the PC should work normally.

No restore points

You can fix OS problems without having restore points. To do this, you will need to resort to the LiveCD program. It needs to be downloaded and written to a USB flash drive with the .iso extension.
Further, all actions will take place in the BIOS. You need to configure boot from a flash drive. To do this, in the Boot section, select USB-HDD in the First boot device line.

Before proceeding directly to recovery, copy all the necessary files to a removable drive. The LiveCD program provides a special menu for these purposes.

We will fix the system error using the backup copy. Connect the flash drive, open the folder Windows\System32\config\ . Files with the names default, sam, security, software, system must be moved to any other folder. In their place, we transfer similar files from the RegBack folder and restart the computer.

The described method will only help if the problem is related to the registry.

Command line

You can resort to "reviving" Windows 7 from the command line if the PC begins to freeze or work slowly, however, the system boots up. Enter the menu "Start" and using the right mouse button, launch the command prompt as an administrator. Issue the rstrui.exe command, which will open the System Restore program. Click "Further". In the next window, select the desired rollback point and click again "Further". Upon completion of the process, the PC should work normally.

You can enter the utility in another way. We go to "Start". To call the command line, press "Run" and write the CMD command. We click on the found file CMD.exe and wait for the launch. Next, enter rstrui.exe on the command line and confirm the action with the Enter key on the keyboard.

It is not always possible to play it safe and create OS restore points in advance. There may be problems that block the option of such a "resuscitation" of the PC. Then you can use another, no less effective and easy option - restoring the Windows system using the system itself.

Based on the diagram:

Icon "My computer"- right mouse button "Properties";
"System Protection";
In a new window, click "System Protection", restore button;
"Further";
Choose a restore point according to the date;
Specify the system disks to be restored;
Confirm the operations and reboot the system.

Restoring Windows 7 using Safe Mode

This method is preferred if the usual system boot is not possible. Then, after pressing the PC power button on the system unit, hold down the F8 key to call "Launch Menu". One of the menu options is "Safe mode". Select it and press Enter on the keyboard. As soon as Windows loads, we perform the algorithm of actions that we described earlier.

System Restore Windows 8/8.1

If you were able to start the OS, you can resume Windows 8 via "Parameters". Hover over the upper right corner and enter them. Click on "Changing computer settings" – . Chapter "Recovery" will offer several options:

"Typical Restore with Information Preservation".
"Delete data and reinstall OS".
"Special Option".

Decide exactly what needs to be done. Then follow the menu prompts.

If you choose the latter method, in the window that opens, click on the diagnostic item. You will be offered the following options:

"Reestablish";
"Return to original state";
"Extra options". This item includes the ability to roll back to the desired resume point.

To resume Windows 8.1 press Win+R and call sysdm.cpl . In the system properties window, on the tab "Protection" specify the required system drive. Click "Reestablish". Clicking "Further", you will be able to see a list of rollback points. Select the one you want and click "Search for affected programs". Changes that have been made to the PC since the selected moment will be deleted. End the process by clicking "Ready".

In the case of working with Windows 8, there may be problems, incorrect Internet operation, etc. To fix this, you can use the classic recovery method through restore points.

Another option is to roll back the system. To do this, open the menu "Start" - "Control Panel" - "Windows Update". Choose an item "Uninstall updates". You can do the same using the command line.

So, in the list of updates that opens, we remove those of them, from the moment of installation of which (we look at the date) problems and malfunctions began. Delete unnecessary files and reboot.

In Windows 8.1, you can perform a factory reset. Important files will not be affected during this operation. The method is effective, but for its implementation, the OS needs to boot without any problems. We use the algorithm:

Right side of the monitor - "Parameters";
"Change settings";
"Renewal and Recovery" - "Recovery";
"Recovery without deleting files".

If you cannot log into the system in the usual way, you must use the disk with the system. Load the installation disk, select "System Restore". We press the button "Diagnostics", And "Reestablish".

Windows 10 System Restore

If you're having problems with Windows 10, press Windows + Pause. Go to "System Protection" and press "Reestablish" – "Further". Select the desired indicator and click again "Further". When finished, press "Ready". The computer will automatically restart and the changes will take effect.

One of the advantages of the "dozens" is the ability to return the settings to the factory settings. This helps avoid having to install the system first. To reset your data go to "Computer Settings" – "Update and Security" – "Recovery" – "Reset your computer". Click "Begin".

You can take care of the possibility of rollback in case of failure in advance. Resume points can be created manually or configured to be automatically created at the desired frequency. To do this, in the settings, in the Update and security item, select the Backup service. Specify where to save copies, click Add disk. After selecting a device, the function will be activated.

You can restore the Windows 10 system again through the use of restore points. In this case, the system will be rolled back to the moment when it was freely loaded and worked without failures. This recovery method is described at the beginning of the article.

If the OS is not loaded, then a warning table appears on the screen with the key "Additional recovery options". Click it and choose "Diagnostics" - "System Restore". We make a choice of a Windows restore checkpoint, we are waiting for a system rollback and reboot.

If such operations did not help and the computer continues to work incorrectly, you can roll back to the basic settings. Some programs and utilities, personal PC settings will be reset, and personal data will be deleted.

This technique is used extremely rarely if the other options described above do not help. The algorithm of actions in this case is as follows:

"Start" - "Setting options"- tab "Updates and Security";
Paragraph "Recovery"- button "Begin";
Choose to delete all files or save some of them.

The system rollback after that will take 40-90 minutes.

Resume using the installation disc

One of the radical methods of fixing the error involves using the installation disk. After running it in BIOS, click System Restore. In the Troubleshooting section, select the desired action. Then follow the system prompts to complete the process.
