Before you figure out how to restore Windows 7 to start, you need to understand what the cause of the problem is. To do this, it will be useful to learn a little general information about how the download occurs and what stages it includes.

General information about downloading

Conventionally, the launch of Windows 7 can be divided into three stages, which, in turn, are divided into several phases.

OSLoader

This is the first stage of system startup, which starts immediately after the BIOS code is executed. First, a small group of drivers starts working, allowing you to read data from hard drive. The Windows 7 boot loader (winload.exe) then begins initializing and loading the kernel. IN RAM The registry hive “SYSTEM” and another group of drivers are loaded. The first stage lasts about 2 seconds and ends with the appearance of the operating system logo on the screen.

MailPathBoot

The main and longest stage of system startup. Visually, it continues from the appearance of the logo until the desktop starts loading. It consists of several phases, the duration of which can vary - from a few seconds to a couple of minutes.

PreSMSS

During this phase, initialization occurs Windows kernels, the plug and play device manager starts working, the remaining drivers start. Errors that occur at this point are usually associated with problems with the main components of the computer or incorrect work their software.

SMSSInit

The visual start of this phase is difficult to determine, but part of it is already the empty field that appears between the splash screen and the appearance of the welcome screen. The system at this moment performs the following actions:

• Initializes the registry.
• Starts the next wave of drivers that are not marked "BOOT_START".
• Starts subsystem processes.

Most often, problems during this boot phase are related to video card drivers.

WinLogonInit

WInlogon.exe is the file that launches the welcome screen, so the “WinLogonInit” phase begins at this point. During this stage scripts are executed group policies, services are started. The duration of the phase varies greatly depending on the processor power.

Failures at this stage are often caused by incorrect operation third party applications, including antivirus.

ExplorerInit

Begins with the start of the shell and ends with the start of the window manager. During this phase, program icons appear on the desktop and services continue to start. These processes are accompanied by an increase in the load on the computer hardware - processor, RAM, hard drive.

Problems at this stage are usually associated with insufficient power of the equipment or its malfunction.

PastBoot

The last stage, which begins with the appearance of the desktop and ends after all startup components have loaded. At this stage, all applications that start with Windows begin to work. After the “PastBoot” stage ends, the system goes into idle mode.

Problems that arise at this stage are usually related to virus activity or incorrect operation of automatically downloaded programs.

Crashes at various stages of loading

Problems at different stages Windows startup manifest themselves differently: some are related to hardware, others to the registry, and others to drivers or important system files. Therefore, it is so important to understand what processes occur when the system starts up so that you can quickly determine the cause of the problem.

Hardware problems

It is often difficult to determine what is not working - some specific hardware or operating system. However, based on some signs, certain assumptions can be made about which device has failed:

All the errors described are usually related to the computer hardware, however, there may be exceptions.

Boot files are damaged

The appearance of a message like “Bootmgr is missing” at an early stage of system startup indicates the absence of critical files, without which Windows cannot boot.
However, sometimes no notifications appear - the cursor just blinks on the screen, but no progress occurs.

Bootmgr is a standard Windows boot loader that is not accessible to the user as it is stored on a separate hidden section. You cannot accidentally delete it, but you can unknowingly format a hidden volume using external media.

When booting from external media, the hidden volume with the bootloader looks like this:

Other files important for startup are stored on the system disk in the “Windows” directory. System registry data is also stored here.

The registry is damaged

If the registry is damaged or inaccessible, Windows may not even start loading. In this case, the system usually diagnoses the error on its own and offers to run the recovery tool.

Often, the built-in system restore tool can help you fix a registry problem by copying its configuration files from a backup store. However, there are situations when there are no registry files on the hard drive or they are inoperative. In this case, the user must manually perform the system registry recovery procedure.

Startup recovery tools

The easiest way to restore startup is to use the built-in Windows tools:

A list of means for restoring system functionality will appear, in which you must select “Startup recovery”.
The scan will take place and automatic correction detected errors, if possible.

If nothing worked with the startup, you can try to restore the system by rolling it back to its previous state. Everything is standard here: select a control point with a working configuration and return the system to that period.

Another method that often helps is restoration Windows boot loader through command line. You can also launch it through the “Recovery Options” menu. On the command line you need to enter several queries (all commands are entered without quotes):

After all commands have been successfully completed and the report appears, Windows 7 should start up normally.

Windows 7 has become a classic for home use; it is installed on every second computer, despite the development of new operating systems from Microsoft. Having entered the market in 2009, the “Seven” still cannot get rid of problems during the launch, which pretty much spoil the nerves of the multi-million user audience. To simplify the life of a user whose computer is running “Seven”, this article was written. In it we will look at how to perform Windows recovery 7 if it doesn't start.

BOOTMGR is missing

The most common problem that appears during the launch of the “seven”.

The reasons for its appearance may be:

• damaged sectors of hard disk or non-working cells SSD memory, on which Windows 7 is installed (in most cases, you can restore them);
• spontaneous power outage or reboot of the PC using the “Reset” key;
• virus activity (very rare);
• incompetent user handling of hard disk partitioning utilities.

There are several ways to make the error disappear. We will look at how to restore a computer using the OS itself.

• If you encounter problems while starting Windows 7, press F8 to bring up a menu with a list additional parameters start the computer.
• Select the “Troubleshooting…” option.

• Select Russian language and click “Next”.
• Choose account with administrator rights.
• Click on “Startup Repair” so that the operating system tries to find and fix the problem on its own.

• If the error is not corrected, launch the command line from the OS renewal options window.
• We enter the commands sequentially:

“bootrec.exe /FixMbr” – writes MBR to the system partition;

“bootrec.exe /FixBoot” - creates a boot record on the system volume.

• Reboot and start the computer.

If after following the steps above, the PC still does not detect Windows 7 installed during startup, run the bootrec.exe command with the “RebuildBcd” attribute through the command line.

It will scan all long-term storage devices installed on your computer for the presence of operating systems installed on them that are compatible with the “seven”, and will allow you to add them to the download list.

And in the very the latter case, when nothing helps to restore the launch of the “seven”, reserve old folder BCD responsible for starting the PC, and create a new one. This is done using the following chain of commands:

"Disk boot failure" problem or message with the text "Insert system disk"

The startup error is caused by one of several reasons, the essence of which is as follows: the computer is trying to find boot entry on a disk that is not bootable. Factors that prevent Windows 7 from starting:

• The device from which the computer starts to boot is not system disk– try disconnecting all flash drives, phone, camera, including external hard drives, and reboot the system.
• Check the BIOS settings that determine the priority of boot devices - there is a high probability that the computer starts booting from a disk that is not the system one. Also look in the BIOS or through one of special utilities, on which Windows 7 is installed.
• Reconnect the HDD to a different cable and power cable; perhaps the problem lies in the unreliability of the connection or damage to one of the cables, for example, due to its significant bend.

The list of reasons can safely include the lack of installed Windows 7 due to the fact that the disk with it was formatted due to the carelessness or inexperience of a novice user, and reinstalling it or restoring a deleted partition will help here.

If none of the options brings the desired result, try restoring the OS as described in the previous paragraph, and also make sure that the hard drive is working.

Inability to start Windows due to damaged registry files

Among other things, Windows 7 may not boot due to damaged files registry

As a result, the computer will inform the user about the problem and launch an application that allows you to restore the operating system.

But the remedy for automatic recovery Windows 7 is not always effective and, for example, if there is no backup copy of damaged data, the user will have to manually restore the operating system.

• Call up a window with an extended list of Windows launch options using F8.
• Select “Troubleshooting...”.
• Next, click on the link: “System Restore”.

• In the first window, click “Next”.

• Select one of the created points and click “Next”.

• We confirm the completion of the specified operation by clicking on the “Finish” button and wait while the OS is restored.

After a few minutes, Windows 7 recovery will complete, the computer will reboot, and most likely will start normally.

Hello friends! The fact that Windows 7 likes to scare you with all sorts of things blue screens and other mistakes, I think everyone knows. But not everyone knows how to deal with these problems. Today I will write what to do if Windows 7 won't boot and how to try to get the system working again.

So, we insert the installation disk with Windows 7 into the computer drive and reboot it. If you see an inscription such as the one below in the picture, then press any button and wait until the window with the choice of language appears.

Well, if you didn’t see such an entry, but an error appeared, that is, the computer tried to boot as usual, then we set . After this, reboot the computer again.

We see a window with a choice of language. Select Russian and click “Next”.

In the next window select "System Restore".

After searching installed systems on your computer, select your system in the list (most likely it’s the only one there), and click “Next”.

Now we have the opportunity to choose one of the methods to restore Windows operation 7. If you have it enabled "System Restore", then you can try this method. If, for example, you have a disk with a recovery image, you can try to repair your computer using it by selecting “Restoring a system image”. You can also run “Command line”, which, by the way, can be useful in other ways to solve system errors.

But I advise you to start “Startup recovery”. After you select this item, the utility will scan your computer and if it finds a problem that prevents Windows 7 from loading, it will try to fix it.

If this method did not help and Windows 7 still does not boot, then you need to look for a solution to the problem, for example, using the words from the error or code. You can also use the search on this blog, perhaps I have already written about such a problem. I hope I was able to help you. Good luck friends!

Greetings to all. Typically, if you have problems starting the operating system or the lights turn off during operation, a list of possible startups appears when you next boot the system.

In order not to mislead you and teach you some nuances, I will share some very useful tips. So, if the system did not boot but provided a boot choice, then I recommend selecting the following option - Last Known Good Configuration or loading the last good configuration.

This start option cancels any changes made to the registry key CurrentControlSet which directly caused the problem.

This registry key determines the values ​​of hardware parameters and all drivers installed on the system. Function loading last known known configuration will replace the contents of the above registry key with the data stored in the backup copy that was used during the last successful startup of Windows.

Reboot the computer. After sound signal press the F8 key and hold it until the operating system start selection menu appears. From the list of launch options that appears, select and activate it by pressing the key "Enter".

Remember, you only have one attempt to restore the last one. successful configuration systems.

In general, if you were unable to restore the system after starting the OS from the mode, then this means only one thing - the backup copy is damaged. In this case, this recovery method will not help us.

1 Recovery Console

This method involves using the utility "recovery console". The more complex the problem of loading the operating system, the more serious the approach to solving it should be. The boot CD with the installation system usually contains a very useful utility - "Recovery Console"

To autorun a bootable Windows CD, place it in DVD-CD drive and restart your computer. As soon as the computer restarts and the drive begins to read data from the disk, you will see the Setup and Installation Wizard dialog box.

This will happen if you are in BIOS settings in download priority "Boot first device" You put "DVD/CD-ROM". I wrote about this in more detail in the article -. Once the download begins, follow all instructions that appear on the screen.

The program will provide you with a selection of basic files to run the installation program. The installation wizard greets you with the phrase "Welcome To Setup". Now all you have to do is press the key "R" which facilitates the opening of the recovery console.

Now the Recovery Console dialog box has opened in front of you. Here we will see a folder with files and also a request to select operating system which you plan to start working with.

Next, you have to press the key with the number corresponding to the operating system number, then the program will ask for the administrator password, if any. Well, now you have it full access to the command line.

I wrote more about how to work with the recovery console in the article -

3 Fixing damage to the Boot.ini boot file

At the initial stage of Windows OS startup, the Ntldr program accesses the boot file Boot.ini. As a result, the program determines the location system files And available options to continue downloading.

This is precisely why, in case of damage to the boot file Boot.ini, the operating system cannot continue or even start booting correctly.

In the event that Windows OS does not boot and the reason for this is a damaged file Boot.ini then the recovery console toolkit will help you - Bootcfg.

To start it Bootcfg you will of course need to start the system from boot Windows disk HR. To run the command Bootcfg, you need to enter into the command line of the management console: Bootcfg /parameter

Where /parameter- this is one of the functions that I will tell you about now.

Add– scans the hard drive for all installed operating systems. In addition, it adds the identifiers of new operating systems to the boot file Boot.ini.

Scan- scans the hard drive for all installed operating systems.

List– displays a list of records in the file Boot.ini.

Default– displays the identifier of the operating system that is being run during startup

Rebuild– completely restores the Boot.ini boot file. The user is given the opportunity to control every step.

Redirect– in administration mode this function allows you to redirect download operations to another designated port. It has several subparameters, or rather two: | ./Disableredirect – Disables redirection.

It is worth noting that in Windows Xp and Windows 7 boot.ini is formed differently. I have written several articles on the topic of boot.ini for XP and 7:

4 Repairing a defective Master Boot Record

The master boot record uses the first sector of the hard drive and carries out the boot procedure for Windows XP. The entry contains a table of all available hard drive partitions and a small program "primary loader" The primary bootloader, in turn, is responsible for placing the active or boot sectors in the partition table.

Once placed in the table, the boot sector begins to start the operating system. If suddenly the boot record is damaged, the active sector will not be able to start the system.

In order to eliminate this problem The recovery console includes the Fixmbr program. Booting from installation disk and activate the recovery console.

In order to run the Fixmbr command, you need to enter the following into the command line of the management console: Fixmbr

Where - the compound name of the disk for which there is a need to create a new master boot record. The qualified name for the main boot drive C:\ will look like this: \Device\HardDisk0

5 Restoring a damaged HDD boot sector

The boot sector is a small section of the hard drive dedicated to storing data in the operating system, having file system NTFS or FAT32, and it is also a fairly small program that helps in the process of loading the operating system.

In the event that the system refuses to start precisely because of inoperability boot sector The recovery console tool can help you FixBoot. To do this, you need to load the installation disk and go to the recovery console menu.

In general, I have already indicated above how to do this. In order to launch this program you will need to enter the following in the command line of the management console: Fixboot:

Where- the drive letter that requires creating a new boot partition.

6 Quick reinstallation of Windows

In the event that the system cannot be started and you do not have a backup copy, you can perform a Quick Reinstallation of Windows.

This procedure involves reinstalling the operating system in the same directory (similar to updating old version system to a newer one) and can fix almost any Windows boot problem.

Place boot disk into the DVD/CD drive, then restart the computer. Once the disk is recognized and reading begins, you can begin the installation procedure. During installation, a license agreement will appear.

In order to agree to the terms of the agreement, press the F8 key. Next, the program will scan all installed Windows versions. As soon as at least one of the versions is found, the installation screen will appear.

In order to start restoring the version of the system you need, you need to click "R", and to start the installation "Esc". The system recovery procedures will start. The installation wizard will now begin checking the disks for functionality, and then begin a quick reinstallation.

Remember, after reinstalling or recovering a damaged installation, all updates will have to be reinstalled again.

7 How to cancel automatic reboot

As a rule, if an error occurs during stable operation of the system, the operating system automatically reboots.

When an error occurs directly at system startup, a cycle of endless reboots occurs. In this case, you need to disable the function of automatically rebooting the system upon failure.

At the beginning of the operating system startup or after POST, press the F8 key, which will open a menu in front of you "Extra options".

Next you need to select the item "Disable automatic reboot on system failure" and activate it by pressing the key "Enter". Now, when Windows XP starts up, it will display an error message, the essence of which will tell us about the malfunction.

We are restoring the operating room Windows system from a backup.
If one of the system recovery methods did not help you, then there is a chance to restore the operating system using backup copy(if you have one).

The recovery algorithm completely depends on the program you are using. backup, which provides you with all the necessary instructions.

Conclusion

There can be many recovery methods and reasons why Windows does not boot. The main thing is that the system is mostly recoverable and you don’t have to perform. That's all. I wish you success in dealing with the problem.

If a user has a problem when Windows 7 does not start on a computer or laptop, then this article will help solve this difficult problem. Starting Windows 7 is sometimes impossible due to errors occurring in the system after hardware problems, incorrectly installed software, malicious utilities, etc.

But the most common reason why Windows 7 sometimes won’t load lies in the operating system itself.

Solution

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 completely, this usually confuses novice users. Although if available detailed instructions, the question: “What to do?” will not appear even for beginners. If the cause of the problem is a hardware failure, then this will be indicated by the signal from the speaker of the laptop or desktop computer during the POST test. If this is the case, then the OS will not start.

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

Instructions for action

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

What to do if the above instructions did not solve the problem?

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

1. Insert the installation disk into the PC drive;
2. Start the system from the disk (in the BIOS the appropriate order for booting the system from media must be set);
3. In the window that appears, click on “Apply recovery functions that resolve OS boot problems” and click on “Next”;
4. Then in the “OS Recovery Options” menu, click on “Startup Repair”;
5. Wait until the system analysis is completed and the causes of failures are eliminated;
6. Reboot the PC;
7. In the BIOS, set the system to start from the hard drive ( When exiting the BIOS, be sure to save the adjustments made);
8. Restart the computer again;
9. Ready! Windows 7 will now 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 about restoring normal loading of the “Seven”. The only changes are that simply in the “ ” menu you now need to specify the section “Command Line”.

What to do when you fail 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 classified as a typical failure of a bootable OS distribution. You will need to do all further actions in Windows safe mode. It is recommended to analyze drive “C” for the appearance of broken clusters.

To login " safe mode» you must do the following:

Why are preventive measures important?

Windows 7 has special system, which can make special reference points, with the help of which, if necessary, it is restored. By using 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 occur due to adjustments being made to the registry.

It should be noted that in “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, it is possible to independently configure protection for files along with system data, or you can do this separately.
