Greetings, dear readers.
Computers often fail for a variety of reasons. If this problem is directly related to the operating system, the best solution is to reinstall. But what to do if there are important files left on the main disk or desktop? After all, when you reinstall everything, everything will be deleted. The solution is a tool such as Windows 7 system recovery from disk. This function allows you to restore the functionality of the operating system when the latter refuses to load.
In addition to a malfunctioning computer, we also need a Windows boot disk. And this can be either a plastic carrier or a flash drive. Moreover, it is desirable that this be the same image from which the current shell was installed. Otherwise, due to a mismatch of versions, the process may not proceed.
If the element from which the current system was installed is lost, try to find it on the Internet on another computer. Download the disc and save it to your hard drive.
Once the system image is on one of the partitions, it must be correctly written to a portable device. To do this, use one of the many programs. For example, I like Rufus. The application allows you to complete the task as quickly as possible. It has an intuitive interface, so anyone can create a disk.
Procedure(to contents)
There are many reasons why Win 7 can become so faulty that it stops loading. To solve the problem, you need to use a tool that allows you to return everything to its place. It runs through BIOS:
It is worth noting that some laptop manufacturers even create special software that allows you to quickly return the device to functionality. For example, HP offers “Recovery manager”, Samsung – Solution. In general, any large company provides similar functions.
I hope you can easily figure out how to use the tool built into the system. Believe me, you can use it to correct a variety of errors.

BIOS is a tool for global configuration of the operating system. Practice shows that it is best to restore Windows OS through the BIOS, especially in cases where no other tricks help.
Of course, there are situations when it is no longer possible to restore, and often this happens for the reason that the system itself has critical damage, which can be corrected by completely removing and installing the OS.
How to restore the system through BIOS - necessary tools
To restore the system, you need an installation (or boot) disk with Windows. You can also use a flash drive, since people don't always install disk drives these days. If the OS image is written to the media, the hash sum should be checked; for this it is advisable to install the HashTab addon. The hash amount is recognized in the information for the image, and then checked in the properties of the image (already written to the media).
How to restore the system through BIOS
- Immediately after entering the BIOS, we need to select a storage medium that will automatically boot when the PC is turned on. To do this, press the F12 key and select BootDevicePriority from the Boot menu. For example, if we have a bootable DVD, then we need to select the appropriate device (with a DVD attachment). For a flash drive or external drive, select USB HDD.
- You need to reboot the computer by clicking the Reboot button in the BIOS menu. The system will ask you to press one or another key to launch the media. In the latest BIOS versions, startup occurs automatically.
- As a result, when the installation disk or other media boots, several options for system-related operations will appear, including “System Restore.” You should click "Next" to begin this process. The current version of the system will be determined, after which it will become clear whether it is really possible to restore (if the OS version does not match or even the edition of the current system, it will not be possible to restore using standard means). After the restoration process is completed, you need to click the “Yes, ready” button, after which the PC will reboot, and the system will be already restored. Before rebooting the system, you should remove the disk or flash drive from the computer, otherwise these media will autoload.
- It is important to understand that with a complete system recovery, programs and games on the personal computer will be deleted, but at the same time, files such as images, music, archives, etc. should remain.

How to run a computer system restore
Windows is a popular user operating system that runs millions of computers, laptops and mobile devices.
The environment is characterized by high performance and stability, but it also sometimes crashes.
By knowing how to run System Restore, you will protect yourself from problems associated with such failures.
A restore point is a copy of the state of the system at a specific point in time. Windows is programmed to independently create restore points when changes are made to the configuration as a result of installing drivers, network components, programs, etc. (see What programs are needed for a computer).
Checkpoints are also created every week if no major changes have been made to the configuration within the previous 7 days.
If desired, the user can create a new restore point himself. This is done without the need to use third-party software, through the menu of a standard tool called “System Restore”.
To get to your destination, open Control Panel
Go to the System and Security tab.
In this menu, select the System category, from there go to Advanced system settings. Here, select the “System Protection” tab.
alternative path – “This PC” → “Computer” → “System Properties”
The procedure is the same for all current OS editions. In Windows 8.1 and later, you can additionally activate/deactivate protection here.
To create a restore point, click the button of the same name and set the desired name. Additional parameters are also entered here: the space allocated for storing recovery points, etc.
The list of copies is available on the “System Restore” tab. If Windows starts behaving suspiciously, go to the specified dialog and roll back to the last working state.
System recovery through BIOS using a recovery disk
If the computer does not boot, perform a recovery through the BIOS. To do this, you will need a special recovery disk or with a windows installation image.
Follow the procedure below:
- insert the disk/flash drive and reboot the device. As soon as the laptop/motherboard manufacturer's splash screen appears, click the Del key several times (a popular option for entering the BIOS). If Del doesn't work, try Esc or F2. If this does not work, check the button for entering the BIOS in the instructions for the motherboard (see How to find out the characteristics of your computer);
- in the BIOS go to the 1st Boot Device tab (the name may be different, but the essence remains the same). In the menu that opens, select the disk/flash drive as the first boot device. Click the F10 button or manually select the option to exit the BIOS and save the changes made. After turning on, the computer will prompt you to press any key to boot from a flash drive or disk (see DVD drive does not read discs). Do this and wait for the first dialog box to appear;
- The bootloader will offer to install Windows or restore it, eliminating existing problems. Select the appropriate option and follow the installer's further instructions.
After waiting for the first dialog menu to appear, click the R button on the keyboard of your computer/laptop.
A window will open with a list of installed operating systems. If there is only one, you will be shown only the C:WINDOWS folder (the disk index may differ depending on which partition the OS was originally installed into). Click Enter.
A command prompt will open. You need to enter fixboot. Next, click Enter. After this, confirm your intentions by pressing the Y button. The system will begin the process of repairing the boot sector. After waiting for the message that the boot sector was successfully created, enter fixmbr into the command line.
Confirm your actions again by pressing Y. The program will create a new boot entry. After waiting for notification that this process has completed, enter Exit at the command line. If everything went well, the device will reboot and it will start working normally.
After completing the above steps, open the BIOS, find the 1st Boot Device menu there and configure the computer to boot from the hard drive. If you do not do this, the computer will continue to try to boot from a flash drive/disk in the future, which will not have the best effect on its startup speed (see How to increase computer performance).
Features of Windows 10 system recovery
Having updated to the latest version of Windows 10, many users were unpleasantly surprised that the recovery function is disabled by default. If you encounter a similar phenomenon, first of all, activate the recovery function.
To do this, open the “Control Panel”, go to the “System” section. On the left side of the dialog box, select the "System Protection" link.
Going to “Protection Settings” (you can find it by opening Protection and in the Properties subcategory), select the system drive and click “Configure”. On the “Recovery Options” tab that opens in the “Protection” menu, activate the function by placing the switch in the appropriate position.
If a notification appears with text warning you that some old points may be deleted, confirm your intentions by clicking Yes/OK.
Otherwise, the procedure for restoring Windows 10 is no different from resuscitating earlier versions of the OS.
Use any of the appropriate instructions previously discussed.
Possible errors during system recovery
In the vast majority of situations, the described recovery methods allow you to bring Windows back to life. Along with this, various failures and errors cannot be ruled out.
If you use a special disk or flash drive, such problems do not arise: either Windows is restored and you continue to use the computer normally, or you simply forget about the failures that occurred and reinstall the OS (see How to install windows on Lenovo).
The user has to deal with errors (they are indicated by a certain index consisting of the letter “x”, zeros and additional letters/numbers or a text description) mainly in cases when Windows is loaded and attempts to restore the system are made through the corresponding section of the Control Panel.
Under such circumstances, before resorting to drastic measures (reinstalling the OS), you can normalize operation through Safe Mode.
Do the following:
- Press the computer's power button, and then click on the F8 key several times until a menu of additional boot methods appears. If before this the computer prompts you to select a device to boot, select the hard drive and then click F8 until the mentioned menu opens;
- highlight the line “Troubleshoot computer problems” and click Enter;
- wait until the recovery program starts;
- in the menu that opens, click Next;
- in the section that opens, enter the name of the computer administrator and click OK. By default, the account created during the installation of Windows and the first boot of the system has administrator rights;
- in the section for selecting the appropriate method, double-click on Restore OS image;
- wait until the console opens, then press 1;
- wait until the system prompts you to press Y as confirmation of consent to clear and return the disk storage to its original state. Confirm your choice. If nothing happens, change the keyboard layout to English (see The language bar has disappeared);
- wait for the process to complete, reboot the device and try turning it on in standard mode.
If this does not help, use the previously discussed recovery method from a disk/flash drive.
Now you know how to normalize the operation of Windows. The information obtained will help you not only to correctly navigate in the event of failures in the OS, but also to save on the services of third-party computer tuners (see Laptop does not turn on).
Most PC users are familiar with the terms Windows and BIOS. However, not everyone realizes that in some cases the operating system can be restored, and it does not necessarily need to be reinstalled. After all, reinstalling the OS in some cases can cause invaluable harm to existing data. And therefore, many will be interested in learning how to restore the system through BIOS. Read about this in our article.
System recovery via BIOS
Modern technologies are developing rapidly, but most of the principles and methods of operation of technology remain unchanged. Each new version of the Windows operating system family receives a more advanced set of functionality. For example, if there is a software failure or the installation of any drivers, the process of restoring the system in a newer OS will be much faster.
At the moment, system recovery occurs through BIOS. Even other types of systems (like Linux) contain an OS recovery option. Therefore, it is very important to know how you can make Windows work after a virus attack or a critical crash. At this point in time, this can be done using an installation disk (flash drive), a special resuscitator, and in more modern versions - from an SSD drive or a special hard drive partition of your PC or laptop.
How to restore the system through BIOS
It should be recalled that Microsoft stopped supporting the Windows XP version in April 2014. However, even despite this, quite a lot of companies (including in the USA and Europe) continue to use the services of this OS. Therefore, the question of how to restore a Windows XP system through BIOS without a disk remains quite relevant. After all, even taking into account the good stability indicators of this system, it does not tolerate frequent installation and removal of software (especially if it is not certified).
Before restoring the Windows XP system via BIOS, find the installation disk with this system, and then:
- insert it into the CD-ROM and reboot the device;
- When starting the system, press the DELETE, F1, F2 key to enter the BIOS;
- click the Boot Device menu item;
- select the optical drive first, save the changes and restart the PC:
- after the line “Press any key” appears on the screen, press the spacebar - the functionality of the installation disk is activated;
- in the dialog box that appears, press the “R” button, then select the desired OS version (if there is more than one on the PC) and press Enter;
- now enter fixboot in Latin letters, press Enter, and then confirm with the “Y” key;
- the process may take some time, after it is completed, enter the fixmbr command into the line and press the keys, as in the previous step;
- entering the Exit command will reboot the PC, after which you can work as usual.
Thus, you were able to save yourself from a rather lengthy OS installation process. Also, do not forget to enter the BIOS using the method described above and change the method of booting the system from CD-ROM to hard drive.
As you can see, getting Windows XP back up and running is not that difficult. Use our tips on how to restore your system through BIOS and enjoy the smooth operation of your PC for as long as possible. In more modern versions of Windows (7) you can restore the OS in even fewer steps - don’t be afraid to use advanced products!
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 recovery cannot be performed using the standard method, you can do so through the BIOS.
How to restore Windows 10 via BIOS.
But this method can only be used if you have an installation disk or flash drive with a distribution kit of a licensed operating system with the version and bit depth that you have installed; this option is not possible without an external drive.
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 motherboard model 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 the “Advanced options” item.
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 and your Windows was successfully restored after the above steps, then you will need to go into the BIOS and return the hard drive boot priority to first place.
— How to restore Windows 10 via the command line.
If you did not create a checkpoint, you can try restoring the Windows 10 system 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 restoring the Windows 10 bootloader, the system needs to be checked for damaged system files.
Options for solving problems with damaged system files
- The boot sector of the operating system is damaged.
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. - The boot.ini file has disappeared.
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 drive 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 the boot disk automatically. System recovery and rollback are quite quick and trouble-free.
Often, users of computers running Windows 7 encounter problems with the operating system. Problems with your computer usually appear when it slows down a lot and programs won’t open. Also, the computer may not start at all or may do so every once in a while.
The reasons that cause problems in the performance of the operating system can be very different. For example, if a computer gets hit 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 a problem with the performance of a computer on Windows 7, you need to roll back to the previous one. recovery point.
To protect the OS, Windows 7 uses restore points that the system periodically creates. Essentially, restore points are previous state of Windows 7 system files. To help Windows 7 PC users, we have prepared material that will describe the detailed process of restoring the system in various ways.
Restoring performance in a busy 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 to the window where we 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 in front of us “ Properties of the system" on the " tab System protection" You can also get to this window in the standard way through the menu “ Start". The next action is to press the button Recovery….
After clicking, the System Restore window will open. It will ask you to restore the system using a recommended access point or select another one. We'll stop at recommended restore point.
This window requires confirmation for the selected recovery. To confirm, click the Finish button.
This button will bring up a message warning that after the recovery procedure it will be impossible to return to the previous parameters of the seven. By clicking Yes in the message, we will begin restoring the Windows 7 system.
If the process of returning to the previous state occurred without errors, a corresponding message will be displayed.
If you are unable to roll back to previous settings using the recommended point, 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.
Restoring the computer's functionality when the OS starts
If 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 seven.
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 successfully started in safe mode, then start restoring the seven, as shown in the previous example. In this mode to ensure maximum security many functions disabled OS, including the Windows Aero graphical interface. This is what the running program “” with the command “” will look like systempropertiesprotection"on a system running in safe mode.
We return the computer to functionality using an installation disk or bootable USB flash drive
If the previous two examples do not help you, then you will need to restore 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 installer start window, click Next 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 Next. This action will take you to list of recovery points. Let's choose a suitable point and continue.
A window will appear in front of you, as in the first example. Therefore, we click 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 a message like this.
Emergency recovery of Windows 7 using antivirus
If your PC is infected viruses that interfere with the proper operation of the computer and the first three examples discussed do not help you, then a good recovery method in this case would be an anti-virus life disk from Dr.Web. With this disc you can clean the system of all types of dangerous software. In addition to cleaning, Dr.Web LiveDisk will be able to cure infected objects, which are necessary to restore Windows 7.
The Dr.Web LiveDisk image can be used both for recording to an optical disc and a flash drive. To use Dr.Web LiveDisk on a USB drive, you will need a special program. You can download the program for recording onto a flash drive and the image itself on the official website by going to www.freedrweb.ru/livedisk.
Let's run the recorded image on disk, setting it to boot first in the BIOS.
In the bootloader start window, select first item Dr.Web LiveDisk and press Enter. These actions will start loading Dr.Web LiveDisk.
After downloading Dr.Web LiveDisk, we will get a full-fledged Linux-based operating system. As written earlier, the main purpose of Dr.Web LiveDisk is to clean and treat virus software. Therefore, this OS has a built-in antivirus Dr.Web CureIt!. This antivirus runs with the OS.
Click on Dr.Web CureIt! button Start scan, which will start scanning, cleaning the system and disinfecting viruses.
After checking, Dr.Web CureIt! will remove or cure infected objects.
Since there will no longer be malicious code in the system, you can safely restore the system in the three ways described above.
If, after checking the system files, you are unable to restore your Windows 7 system, then the only reasonable solution is to make a complete 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 your hard drive, including the operating system. After restoring using this method, 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 to create an image, indicate the location to save it and click Next.
In the window that appears, all that remains is to click the Archive button, which will start the image creation process.
You can restore the created image with Windows 7 and all the information on local disks using the installation disk. The recovery principle is shown in the second example, only when choosing a recovery method you need to select " Restoring a system image" and indicate its location on the saved drive.
Alternative methods to restore the Windows 7 operating system
In addition to standard recovery methods, there are alternative software that perform the same function. The most interesting solution that allows you to perform system recovery is the program Acronis True Image 2016. This is a proprietary software package from Acronis.
First of all, download and launch Acronis True Image 2016 from a shortcut on the Desktop. When launched, the program will ask for a name and password.
Now let's set it up Acronis True Image 2016 so that he can do backup of the entire disk with Windows 7 OS. This setup 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 over a certain period of time. So, let's start setting up. To do this, select the storage type 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 “ Options" and let's move on 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 we set, a backup copy of the system will be created in 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 you have created a backup copy on your computer, then Acronis True Image 2016 will find her himself.
So we press the button Restore your computer, after which the program will completely restore the system to the state it was in when the backup was created. Also, if you cannot start Windows 7 on your computer, Acronis True Image 2016 There is a boot image for this that can be burned to disk.
You can download this image from your account page. You can obtain a password and login on the official website www.acronis.com. The principle of operation of the bootloader is the same as with the desktop version. Load disc from Acronis True Image 2016 on your computer you can by setting 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.
An example of launching an Acronis True Image 2016 boot disk
To launch the disk Acronis True Image 2016 When starting the system, you must set the boot mode from optical drive first in the BIOS. For example, for the MSI A58M-E33 motherboard, these parameters in BIOS mode look like this.
Another boot method is to use hotkeys to call up the drive boot menu in the BIOS. 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, it will open drive boot menu in BIOS.
After booting from the Acronis True Image 2016 disk, we will be taken to this menu.
In this menu you need to select Acronis True Image 2016, after selection the program will start.
The example shows that launching a boot disk Acronis True Image 2016 Using the required BIOS mode is not at all difficult.
Let's sum it up
In this article we have discussed almost all the methods and parameters system recovery. We also looked at ways to restore the seven using alternative software and using an antivirus. Which method to choose to restore Windows 7 depending on the situation is up to you.
To summarize, 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 discussed 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 confidently say that I can perform a system restore.
Video on the topic
BIOS- a basic information input/output system, in other words, a microcircuit that allows you to start a computer even if there is no operating system installed on it. The BIOS stores the basic configurations of the computer and allows you to change them in a special system menu. Among these configurations are those that are necessary to successfully launch an operating system recovery.
If restoring the operating system using built-in programs is impossible due to the inability to start it, recovery through BIOS comes to the rescue. Using this method, your main files will be saved, and the computer will be able to start successfully again.
Recovering the system using BIOS settings
To begin recovery, you must have a boot disk with Windows preinstalled on hand. Alternatively, you can use a bootable flash drive.
Attention! The SETUP system menu stores configurations that are best not changed by an inexperienced user. Changing settings without knowing their functions can lead to improper operation of the computer and, as a result, irreparable damage.
Step 1: Setting device boot priority in BIOS
Stage 2: Recovering the system using a boot disk
- Startup recovery.
If there are hardware failures or improper operation of the operating system due to viruses, this function is useless. But, in the absence of the above, you can try. - System Restore.
This is the right option for us because it uses the boot files on the recovery media. - Restoring a system image.
This option is used by users who restore the system using a backup.
This completes system recovery using BIOS. If you do not have a bootable image of the operating system at hand, unfortunately, this recovery will not work for you. If both the boot image and the recovery checkpoint are missing, you will have to reinstall the operating system. All files located on the system disk will be completely destroyed in this case.
Note! To avoid losing files that are important to you in emergency situations, save them on a second logical drive, separate from the system one.
Never be lazy to copy the operating system image, at least once a month. One hour spent a month can save your valuable files and, most importantly, your nerves.
