The laptop fell and Windows 7 does not boot. Windows does not boot: why? What can be done to solve the problem

All tips

In this article we will look at all the popular reasons why Windows 7 or xp does not load on a laptop or computer and a black screen with inscriptions appears. Those. Possible software problems and ways to resolve them will be discussed. This will be a continuation of the first part of our review, in which we looked at possible options for why the computer does not boot, and hardware problems (with hardware). So, if you haven’t found the answer to your question here, be sure to read the first part - maybe it’s there.

If your PC shows absolutely no signs of life and does not react in any way to pressing the power button, then we recommend that you read the article why your computer won’t start. It discusses the main causes and ways to eliminate this breakdown. But don’t forget that if you don’t want to deal with the problem yourself, you can always contact our service and order computer repair at home.

We tried to make this review as complete as possible and collected all the most popular reasons why Windows 7 or xp does not start on a computer or laptop. Each case has been encountered many times in our practice. But it is also possible that you will not find a solution to your problem. In this case, write in the comments and we will try to help you.

On a black screen there is an inscription: NTLDR is missing and Windows does not boot

This is one of the most common reasons why Windows xp or 7 does not start. The message "NTLDR is missing" is translated as "NTLDR is missing." NTLDR is a boot file for the operating system, which requires three files (NTLDR, boot.ini and ntdetect.com) to be present on the active partition of the hard drive from which it is configured to boot. If at least one of the files is missing or there is no access to it, then Windows 7 or xp will not boot and will give an error.

Possible reasons and what to do:

The NTLDR, ntdetect.com, and boot.ini files have been moved or completely removed from the disk containing the operating system. In this case, you need to copy the missing computer files from the working OS.
Severe virus infection - a deep scan of the PC for viruses is necessary. You may also need to restore damaged system files.
Too many files have accumulated in the root directory of the system disk.

Unfortunately, due to the peculiarities of the NTFS file system, which is used on most modern computers, simply deleting unnecessary files from the root directory of the system partition is unlikely to help eliminate the problem - Windows will not start anyway. Additionally, you may need to copy boot files from your work PC.

If several operating systems are installed on the hard drive at once, then a conflict may have occurred between them.

You can fix this problem by booting the computer using the operating system recovery disk and manually editing the boot.ini file, which is responsible for the OS boot order.

Windows XP won't boot due to registry problems

As a rule, this problem is specific to this version of the operating system. In the newer ones (seven, eight, ten) we did not encounter such a problem.

Before booting begins, one of the following messages appears on a black screen:

Windows cannot start because the \WINDOWS\SYSTEM32\CONFIG\SYSTEM file is corrupted or missing;
Windows cannot start because the \WINDOWS\SYSTEM32\CONFIG\SOFTWARE file is corrupted or missing.

These messages mean that your operating system registry is faulty. There may be several reasons why this could happen and now Windows XP does not start:

Your PC has become infected with a virus.
You incorrectly shut down your computer by forcibly turning it off using a button or unplugging the cord from the outlet.
Your hard drive is failing (or has already failed).

There are several ways in which you can restore functionality to your operating system. If everything goes well, this can be done even without reinstalling the entire system. But all these methods require deep knowledge of PC software.

A beginner, having made even a small mistake or inaccuracy, risks losing the opportunity for subsequent successful recovery. In addition, you may need to restore personal information located on your hard drive. Therefore, we recommend contacting specialists for this problem.

The following message appears on the black screen: BOOTMGR is missing

"BOOTMGR is missing" is translated as "BOOTMGR is missing." If Windows 7 or XP does not boot and this message appears, it means that the boot sector is missing or damaged.

This could happen due to incorrect installation of programs, a failure in the operating system, careless user actions, or problems with the hard drive. Before trying to resolve the error, you need to diagnose the hard drive for bad sectors.

In order to fix this problem, you will need the boot disk from which you installed Windows. You need to boot your computer from the disk and select “Startup Repair” in “System Recovery Options.”

In this case, the boot sector will be restored automatically. If after this Windows 7 still won’t start, and you don’t know what to do, then it’s better to contact the service. Because restoring the boot sector manually is a very difficult operation. Careless actions can lead to the loss of all information stored on the computer.

Why Windows won't boot and freezes during boot

Many have encountered a problem when, when starting the operating system, a logo with a creeping line appears and the computer freezes. There is no point in waiting an hour, two or a day - Windows will not start.

Here are the main reasons why this can happen:

The operating system has been heavily infected with viruses - in this case, a full scan of the system disk for viruses can help. You can do this by booting your computer from a rescue disk or by connecting the hard drive to another computer.
The operating system has crashed

You can try booting into safe mode and performing a system restore, or try performing a “Last Known Known Configuration” boot. Very often this helps solve the problem. To do this, immediately after turning on the PC, start pressing the “F8” key. A menu should appear where you can select this download option.

Computer hard drive failure.

Due to improper use or simply over time, bad sectors may appear on the hard drive. The information that was written to them becomes inaccessible and, as a result, Windows 7 or XP may stop loading and freeze during the boot process. You can restore and replace bad sectors, but it would be best to replace the hard drive itself. You can read it.

Also, if such a malfunction occurs, you can try “Load last known known configuration”. If this still does not bring results, then in the same menu try the “Safe Mode” item (in English this may be “Safe mode”). When it turns on, try to rollback to the previous state. To do this, in “Start”, find and run “System Restore”.

Blue screen of death appears

Another popular problem is when Windows 7 does not load beyond the logo, but a “blue screen of death” appears. In this case, you will also need to bring up the boot menu using the "F8" key.

There should be an item in the menu called “Troubleshoot your computer.” Click it and the “Recovery Options” window should appear on your screen.

Let us briefly examine the points that are contained in it.

Startup Repair - automatically analyzes problems that prevent Windows 7 from starting and attempts to fix them. It doesn't always help, but it's definitely worth a try.
System Restore - from here you can also “roll back” the system, just like from safe mode.
Restoring a system image - if you have a saved system image on your hard drive, you can restore using it.
Windows memory diagnostics - check system memory for errors.
The command line is for “advanced users”. Using it you can delete, copy or move files manually.

So, first of all, try using the “Startup Repair” item, if that doesn’t help, then “System Restore”.

In this article, we looked at the main reasons caused by a software malfunction of the computer, due to which Windows very often does not boot. We hope that we were able to answer all the questions and clearly explain what to do in this case.

If you have not been able to figure out on your own the reason why Windows 7 or XP does not start on your computer or laptop, and you do not know what to do next, then you can always turn to us for help - the computer help center website. Our service technicians will quickly and accurately determine the cause of the breakdown and eliminate all faults. In addition, they will give valuable advice on how to make sure this doesn’t happen again.

Also write your questions in the comments. And you will definitely get an answer to them.

Very often we encounter operating system problems. The issue is especially unpleasant when Windows 7 does not start at all. But let’s look at everything in more detail. In order to correctly and reliably understand this issue, it would be good to study its main components.

After all, this problem does not happen on its own. In the article we will also tell you what to do to try to quickly resume Windows 7 (if possible).

You can contact our service for a solution to this and other problems of laptops and computers using the contacts in the header of the site and our specialists will do the work inexpensively, efficiently and on time

And so, let's go.

The operating system (OS) Windows 7 and its predecessors are very popular, and a huge amount of money is spent on their development. Despite this, it happens that they often do not work very stable or do not want to start at all.

Moreover, it would seem that you didn’t do anything special at the computer, but Windows works unstable and incorrectly. Well, since a lot of important and necessary information is usually stored on the computer (), a sudden interruption in work can bring a lot of trouble.

You have to take the computer in for repairs, and there is a possibility of losing all important information on the hard drive (as a result, if you try to solve the problem yourself). And these are usually working documents and educational documents, ranging from electronic lectures to coursework and a host of other important files.

Almost everything lost (deleted) can be restored; for more details about this service, read the article recover data. Therefore, you should never hope that “it will carry me through.”

It is important to understand that many problems can be avoided by treating the operating system correctly.

Common reasons why Windows 7 won't start

One of the reasons is the inability to boot due to damage to the OS registry, as a result of which it cannot boot and proceeds according to instructions, i.e. does a reboot in the hope that the next boot will fix the problem.

The situation is, of course, not simple; to understand it, it is worth finding out the possible reasons for its occurrence.

So why might Windows 7 crash? This usually happens for the following reasons:

Failure in computer parts, which can also occur due to problems with the network power supply
Malicious programs or viruses that damage the registry itself (you need a good antivirus, even a free but reliable one will do)
Hard drive failures - its complete or partial failure. Most often without special repairs. service or replacement is not necessary. Moreover, it would be nice to always monitor its status, since you can instantly, if it breaks, lose all your accumulated files on your computer
Problems with the file system can be restored, but the process is not simple and requires special knowledge and tools
Also, if you installed some new device due to which a failure occurs, namely a problem with the drivers of this device, which simply may not be suitable for this operating system
And, what happens not so rarely is mechanical damage to the hard drive, i.e. if you somehow dropped or hit it (the system unit gave in or the laptop was dropped, etc.) or its service life has simply expired

If we summarize for the reasons listed above, then at home you can only cope with point 2.5 at best. Most often, you cannot do without additional help. You ask, what is the benefit of the article then? Well at least:

You save time, do not waste it on unsuccessful attempts to fix the problem, but immediately turn to professional help. This way you save time and sometimes money
You will also find information here about what breakdowns most often occur, which means you will pay more attention to these points in order to prevent them (fortunately there is plenty of information here on the site and on the Internet in general) or to know how to act most quickly when they occur, which again saves time

It’s unfortunate to conclude, but if you still can’t start Windows 7, you’ll have to reinstall it

There is a lot of information on this site on this issue in case the OS no longer starts and you have to reinstall it. In general, in most cases, this is the most reliable way to get a new high-quality and fast-running Windows.

True, we should not forget that only an experienced master can reliably carry out this process. If you decide to use the services of such a specialist, then simply contact us using the contacts in the header of the site. Don't worry, we're not saying that only we can do this, not at all.

If you can also reinstall and configure Windows quite well, then that’s just great. But it often happens that the user does not have such an opportunity, so in this case we offer our services so that the PC can be restored as quickly and reliably as possible.

Conclusion

And so we have looked at the main ways you can try to get out of the situation when for some reason Windows 7 does not start. Many other factors can influence the startup, we have looked at the most basic ones. We recommend that you contact our service for quality assistance and get the fastest, stably working computer or laptop.

Enter the account name and password:

A menu will now appear with the option to select a recovery tool:

Let's consider their purpose:

Automatic diagnostic mode. Fixes most minor bugs.
Rollback the operating system to a previous checkpoint.
Allows you to restore Windows from a copy that the user saved on your hard drive or external storage device in advance.
The memory test program is launched if problems with RAM are observed. For example, the “blue screen of death” when working with a PC.
Allows you to execute commands outside the running OS.

Using points 2 and 3 is possible only in cases where the user has taken care of creating checkpoints/archiving data in advance.

To begin, select the first item.

The PC will launch the diagnostic tool, which will automatically start working. This one looks like this:

Wait until the end, no matter how long the verification procedure takes. The utility will ask your permission to restore. Click “Restore”:

After another couple of minutes, the software will finish working, and you will see the final window. Click on the marked button and wait for the device to reboot:

A black splash screen with the Windows 7 logo will appear on the screen - the usual startup of the operating system:

If the procedure was successful, then you can easily start your PC and continue to use it as before. If the problem cannot be fixed, and the computer still freezes or does not start when loading, then we try other methods.

Restore from a checkpoint

Windows, by default, periodically creates checkpoints tied to certain events. You can perform a rollback from a working OS, but not in our case.

To do this, open the troubleshooter again according to the previous instructions and run the second option:

After this, we wait for the checkpoint wizard to turn on and follow the algorithm. On the first screen, click “Next”.

We select a save point based on the date when there was no OS malfunction. We continue the procedure.

We start the recovery process with the “Finish” button. After this, a confirmation window will appear.

If the restore is successful, you will see the following window. Reboot the computer.

Wait until your computer turns on. If the operation is successful, the following message will appear on the screen. You can simply close it and continue using the device!

In most cases, the checkpoint option helps when making incorrect changes to system settings or the registry.

If the user previously created a system backup, he will be able to restore the OS state using it. To do this you need to do this:

Open the diagnostic and recovery tool again when you start the computer using the F8 key. Select the third item.

Check the box “Select a system image” and move on to the next step.

The table should contain a list of archived operating systems to which the computer has access. Select the one you need and click “Next”. After this, automatic recovery of Windows from the image will begin. If the list is missing, as shown in the screenshot, it means that the system did not archive automatically.

The software is restored along with all user settings and configuration.

Another option available in the standard recovery wizard. With its help, you can install a backup copy of the registry, diagnose system files, and restore boot files.

Open the corresponding item in the recovery environment:

A regular command line window appears in front of us with only one difference: for cmd launched without Windows, the hard drives are offline. Therefore, entering commands will look slightly different. Enter the line sfc /scannow /offbootdir=C:\ /offwindir=C:\Windows, where the first path indicates the system drive letter, and the second indicates the path to the Windows folder. Press Enter to apply.

Now we wait for the end of checking the structure of system files. If the utility was able to find problematic sectors or data, then the next time you turn on the computer will work properly.

Safe mode

When you turn on your PC, you can launch a menu with an expanded list of actions. Among them there is both Lunch Startup Repair, described above, and other extremely useful tools.

Safe Mode does not always start. If there is serious damage or malfunction of the equipment, this option does not work.

When you restart your computer, press F8. You need to be in time before the Windows boot screen appears. If you click at the right time, you will see the following:

Here you need to start safe mode (normal, with network drivers for Internet access or with the command line). To restore, it is advisable to choose the third option. Then you need to wait until the program downloads all the files:

Externally, Safe Mode of Windows 7 is very different from the standard OS. A simplified interface and a black desktop will appear on the screen. In this mode, you can rollback to a checkpoint.

We can say that the functionality of Safe Mode is an analogue of the recovery tool mentioned above. However, you can run some programs and work with files here, which is a plus.

Let's look at the instructions for starting recovery from a checkpoint:

Open “Start” and go to “Control Panel”.

Go to the “Recovery” section.

Now click the marked button to launch the wizard.

It is not possible to restore using a system image in safe mode (only in normal mode).

Now let's look at the command line functionality in Safe Mode:

We launch the application through a search in the Start menu or Win + R by entering the cmd command.

Enter the command chkdsk /r and press Enter to analyze the hard drive.

Accept the prompt to check the disk at next restart using the Y key.

Restart your PC, then wait until the scan is completed. If possible, the utility will correct errors and damage.

It is impossible to analyze the active partition while Windows is running, which is why the procedure will be carried out during restart.

The next option to use the command line for your own purposes is to restore startup files. This method will help get rid of the error with the text “BOOTMGR is missing”, after which the computer endlessly reboots. In cmd you need to enter the command bcdboot.exe C:\Windows (you need to change the letter of the system partition to yours) and press Enter:

The damaged startup files will be replaced with new ones. After reinstallation, you need to check the “Seven” for trouble-free activation.

Repairing the Windows registry

Now let's restore the registry log via the command line. The properties and capabilities of the registry include recording all system changes. If the user has updated any parameters or installed software, the registry records this. Due to failures in it, problems may arise when starting Windows 7. Consider manually restoring registry backups:

Launch the command line through “Troubleshoot your computer” and enter the command notepad. We will need a notepad to gain access to the explorer.

Press the combination Ctrl + O to make the explorer appear. Now open the path C:\\Windows\system32\config.

Here are the files with the names marked in the screenshot - this is the current registry. You need to rename them. For example, add ".OLD" at the end.

When all the files have been renamed, open the “RegBack” folder, where the backup copies are stored.

Select one file at a time (it will not be possible to copy everything together), press Ctrl + C.

We return to the “Config” directory and use Ctrl + V to paste the backup file. We perform the same operation with all other documents.

Now all that remains is to restart the computer and check the status of Windows

To use this method, you must restart your computer again and press F8.

Pay attention to the “Last Known Good Configuration” item:

When choosing this option, the program selects the optimal parameters of the “seven”, at which the system launched successfully.

Virus check

A protected computer works much more stable and longer. There is often a situation where a PC is so infected with viruses that it refuses to start or be updated through special tools. Since we cannot check this in the usual way, a safe one comes to the rescue. We turn it on, load the network drivers and do the following:

To scan the system and remove viruses, you need a similar scanner. You may ask: can I scan my PC with my antivirus? Of course you can if you have it installed.
Launch the downloaded file. The utility does not undergo long initialization and will not be updated - this is its advantage over antiviruses. On the first screen, check the box.

Now click the “Start scan” button.

We are waiting for the application to scan the entire system. If the ticker stops for a while, don't be alarmed - this is normal.

At the end of the procedure, you will see the following window. If the problem is not a virus, then the threats will not be detected. Otherwise, the program itself will delete them or quarantine them.

Setting download priority

If, when you turn on the computer, a screen appears with the text “DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER,” then there is a high probability that the priority in the BIOS parameters is incorrectly set.

Don't forget to check the connection of the hard drive to the computer, perform a performance test on another device, and run diagnostics. If the equipment is working properly, then “Seven” does not load due to priority.

Let's learn how to open BIOS and work with it:

When the PC just turns on, you need to press F2 on the first screen. After this you will see the following interface:

Control is carried out only by keys (hint at the bottom of the screen). With their help, go to the “Boot” section.

You can save changes and immediately restart your PC by pressing F10. After this, we agree to the action with the “Yes” button.

The appearance and management of the BIOS may vary slightly depending on the motherboard model or specific firmware. However, the principle of operation and the names of the sections are as similar as possible.

If you manage to load Windows, then rejoice - no additional operations will be required, and your OS is working. If this does not give results, then do not be discouraged and move on according to the instructions.

Using a bootable USB flash drive

If you don’t have a boot drive for Windows 7, you can create one yourself using an empty flash drive/DVD and instructions from our website.

So, to launch the bootable media menu, the skill of working with BIOS, acquired in the previous section of the instructions, will be useful. Press the menu start key again (it may differ depending on the model and firmware) when the computer starts, and go through the steps to set the priority. Only this time the connected flash drive is put in first place.

Restart your computer to launch the Windows 7 installer. After that, follow the instructions:

At the language setting stage, click “Next”.

To reset the settings to factory settings, you need to disconnect the computer from the network, remove the battery and after 1-2 minutes put it back. After this, turn on the device and check operation. Remember that with such a reset, the date and time in the settings disappears - you need to set them again.

If the date and time are constantly reset to factory settings, then you cannot do without replacing the battery with a new one.

Option for laptops

If your licensed Windows 7 on your laptop crashes, repairs can be done without diagnostic tools or bootable media. The OS is restored using the built-in recovery utility. Each laptop manufacturer has them differently, but they have approximately similar controls and interface in Russian.

The application can be launched both in the working “Seven” and before turning on the laptop. One of the system keys or a combination is responsible for launching. For example, on HP devices it is F11, on Acer Alt +F10 and so on. Through this application, an OS license is installed, which does not require further activation.

When nothing helps

You may also need the help of a specialist if we are talking about hardware faults. Often the cause is the motherboard, hard drive or RAM. Without professional knowledge, you won't be able to fix your PC.
)

There are often cases when, after installing a program, driver, accidentally deleting a system file or a virus attack, the Windows 7 operating system begins to “slow down” or stops functioning altogether. If there is no important information on the computer, then you can simply reinstall it. Otherwise, the system restore function will help you. This tool returns the OS with all data on the hard drive to a working state.

Windows 7 system recovery methods

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

You can restore the functionality of Windows 7 using:

applying the latest working configuration;
safe mode;
recovery points.

Using Last Known Good Configuration

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

After completing 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, move on to the second method.

Safe Mode is an effective means of resuscitating Windows

Safe mode is a special option for operating systems that does not automatically launch 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 presented below:

A boot disk with Windows 7 OS is inserted into the DVD drive and launched. The system build you use must be the same as that on your computer. Therefore, if possible, take the same disk that you used when installing the operating system.
When a message about autorun pops up, click “Cancel”.
Open the “Run” command window, which is located in the “Start” menu.
Enter the command to check the functionality of system files “sfc /scannow”.
Some time after activating the search for executable files, all damaged or deleted system data will be copied from the DVD disc and restored.
If you want to monitor the progress of the recovery, you need to enter the command line by entering the command “cmd” in the “Run” window. After this, “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 the command line displays data 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 means of resuscitating a Windows system is using restore points. The operating principle of this function is based on the fact that after a certain period of time the existing OS configuration is written to the hard drive. If any software problems occur, you can use the saved points and restore the computer's functionality.

Hello friends! I think everyone knows that Windows 7 loves to scare you with all sorts of blue screens and other errors. 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.

You understand that there are a lot of problems that lead to various errors, as well as the errors themselves. And of course, there are also many ways to fix all these “glitches”! I will write about one method that should be used first if Windows 7 stops loading.

If you turn on the computer, and then an error like “ “, or “ ” appears in front of you (I wrote these two errors as an example, you may have a different problem), then you should first try the method that I will write about now, well and if it doesn’t help, then look for a solution to the problem by the error number or its other signs.

And if all this already seems complicated to you, then it’s better to contact the guys who repair laptops in St. Petersburg, I think it will be easier. Well, if your eyes have already lit up and you want to fix your computer yourself, then read on :).

Windows 7 won't boot? Let's solve the problem.

We only need an installation disk with Windows 7. Some will say, well, that’s all. But even if you don’t have one, creating one is not that difficult. Just download the .iso image from the Internet, and .

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

Now we have the opportunity to choose one of the methods to restore Windows 7. If you have "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!
