Fix Windows 7 won't load. Basic solutions when Windows refuses to boot. Manual registry repair




Good afternoon everyone!

Despite the fact that each new version of Windows becomes more stable and reliable, it still often causes unpleasant incidents...

For example, a seemingly trivial thing, a power outage and an emergency shutdown can easily lead to the fact that after turning on the computer - Windows won't boot anymore (moreover, this also applies to the newfangled Windows 8.1, 10)! Although, of course, there are many more reasons for this misfortune.

Actually, in this article I want to look in more detail at what can be done to restore Windows boot(or at least minimize your losses).

By the way, it’s worth clarifying right away one moment:

And so, now closer to the topic...

The first thing I would advise you to do is pay attention to the screen. You can often see an error message, its code, and description on it (and knowing this information, it will be easier to find and diagnose the cause).

For example, the photo below shows one of the typical errors “Disk boot failure...” (an error related to the boot media, according to its solution, I have). I note that in your case the error may be slightly different (there are quite a lot of them).

In general, all the popular errors that can be seen at the computer boot stage have long been sorted out by many specialists (including on the official Microsoft website).

In general, the message of the first step is simple: If you see a specific error, write it down and try to find a guide to solve that specific problem. The situation is worse when there are no errors at all and it is not clear what to do next...

⇒ By the way!

If after turning on your PC/laptop you just have a black screen (i.e. there is no image on it) - I recommend that you read these instructions:

STEP 2: Disconnect all "unnecessary" equipment from the computer

The next thing I would advise is to disconnect all unnecessary equipment from the laptop/computer: second monitor, printers, mice, speakers, headphones, etc. Particular attention to flash drives, CD/DVD drives, SD cards, and other storage devices.

The fact is that with certain BIOS settings, the computer can “search” for boot entries on the same flash drive, and if it doesn’t find them, it simply won’t proceed to boot Windows from the hard drive.

Note: after you disable everything “unnecessary”, restart your computer.

STEP 3: Check BIOS settings

If you changed the BIOS settings (or reset them, for example) or connected another hard drive to the PC, it may happen that the BOOT section contains incorrect settings (for example, the wrong boot device may have been selected).

As an example, below is a photo of the BOOT section. Pay attention to the sequence: 1st is the CD/DVD drive, 2nd is the hard drive. In some cases, the PC may “refuse” to boot Windows from the hard drive (in this sequence).

You need to: put the hard drive in first place, save the settings (usually the F10 key) and restart the PC.

⇒ Help! By the way, you can simply reset the BIOS settings to factory settings (as a rule, they are universal and by going to them you can solve most problems) -

STEP 4: Try to repair Windows bootloader

STEP 5: scan your PC for viruses

Some viruses can corrupt system files, delete information from the hard drive, and block some functions and capabilities of the OS. All this can lead to a wide variety of problems with Windows, including the one discussed in this article. (moreover, restoring in the previous step can help exactly until the next reboot).

In order to scan your OS disk for viruses (when Windows itself does not boot), you can resort to two ways:

  • remove hard drive from a computer/laptop and connect it to another device on which a modern antivirus with updated databases is installed ();
  • create a LiveCD flash drive (i.e. from which you can boot even if your PC does not have a hard drive) and run the HDD check from it. Now such images for recording on a flash drive can be downloaded from official antivirus websites.

Often, many users wait for Windows to load for 5-10 minutes (some of them, by the way, think that it has frozen and are in a hurry to restart the PC and wait this time again).

In general, the first thing I would advise you to do in this case is check startup(the more programs it contains, the longer it will take to load the OS). Pay special attention to any torrent programs: if you have hundreds of torrents in them, downloading can become very long!

In Windows 10, to view startup, just open the task manager (key combination Ctrl+Shift+Esc). You can also use various specials. utilities, for example, .

In addition, check Windows using some utility to clean up garbage, temporary files, fix errors in the registry, etc. All this together can also seriously affect the speed of the OS.

I have a separate article on my blog dedicated to the best utilities for maintaining and cleaning Windows -

STEP 7: how can you copy your data from the disk if Windows still won’t boot

If all the previous recommendations did not bring success, then before formatting and reinstalling Windows (or some other more radical measures), it is advisable to make a copy of all important documents from the hard drive. You never know...what if something goes wrong?..

Method 1

The easiest way is to remove the hard drive, connect it to another computer and transfer all important data from it. By the way, now on sale you can easily find various “boxes” for connecting an HDD to a regular USB port (it makes the work much easier).

Method 2

That's all for now...

For additions - a special merci!

Many PC users work with Microsoft products. For example, with the corresponding operating systems. They are called Windows (English - “window”). Every year new operating systems are being developed and released. Today, users can enjoy Windows 8 and Windows 10. However, this is not the only software for the computer. There is another very successful Microsoft product. We are talking about Windows 7. The majority of users prefer to work with this software. It has a pleasant and understandable interface, and also copes with its tasks properly. But there are exceptions. For example, there are often cases in which Windows 7 does not load. What should I do? What should the user do to bring the computer back to life? Below we will look at the reasons for failures when loading Windows, and also try to figure out how to troubleshoot the problems.

Main reasons

Windows 7 won't boot? This operating system is considered one of the most successful from Microsoft. Many users prefer it. But the operating system is very vulnerable software. Therefore, errors in its work cannot be ruled out.

Most often, problems loading the operating system are caused by:

  • system failures;
  • PC virus infection;
  • "cluttered" computer;
  • hardware damage;
  • incorrect software installation;
  • conflicting components connected to the computer.

In fact, the situation can be corrected in different ways. It all depends on the problem. If Windows 7 does not boot, the user will have to discover the reason for this behavior (fortunately, this is often easy to do) and then resolve the conflict. And only occasionally do you have to agree to extreme measures.

Download steps

First, let's try to understand exactly how the OS loads on a computer. This way the user can find out at what stage the problems occurred. This will definitely help in the future.

  1. OSLoader. The stage that begins with starting the BIOS. That is, immediately after turning on the computer. First, the BIOS code is executed, then the main drivers are connected. They are needed to read data from the hard drive. After this, the Windows kernel is connected, as well as the registry branch.
  2. MainPathBoot. Largest loading step. It connects all the necessary components and drivers to the operating system. Settings, options, some applications and all built-in services are loaded during MainPathBoot. This stage is displayed on the screen as a blue background with “Windows 7” written on it.
  3. PostBoot. Activated when loading the desktop. This stage completes the download of Windows 7 and connects the remaining applications and programs.

That's all. In fact, everything is not as difficult to understand as it seems. However, you will have to figure out what to do if Windows 7 does not boot. Problems are usually detected at the MainPathBoot stage. But they also happen with PostBoot. At the OSLoader stage, errors with loading the operating system almost never occur. This step only takes a few seconds.

PC Damage

Windows 7 won't load? It is often difficult to understand what exactly happened - a hardware failure or system problems. After all, the computer can behave the same in both cases.

So, if the user thinks that some components on his computer are damaged, they will need to be replaced. Ideally, take a closer look at the behavior of the operating system. Very often, Microsoft tells the user what the problem is. For example, by displaying the “blue screen of death”. But more on that later.

After replacing the faulty parts, the error loading Windows should disappear. The following scenarios may indicate such a problem:

the same driver constantly fails on the computer;

  • "blue screens of death" occur;
  • the sounds of the OS are heard on the computer, but there is no picture on the screen;
  • sudden freezing of the Windows boot process;
  • turning off the computer while processing the OS boot stages.

Which of these phenomena indicate what? This will be discussed below.

Signals - pointers

Did you encounter an error loading Windows 7? Often failures are associated with hardware damage. But what should you check first? It all depends on the situation.

Previously, we provided several indicators of computer hardware damage. But what exactly do they point to? Let's try to figure this out.

So, users can focus on the following data:

  • driver errors - a malfunction of the device for which one or another software package is installed;
  • “blue screen of death” - problems with RAM (but there are exceptions);
  • no picture on the screen - damage to the video card;
  • stop OS loading - ;
  • power cut while the PC is booting - a problem with the power supply.

Can the listed phenomena occur when some computer components conflict? Yes. For example, if after installing a new video card the OS does not show a picture on the monitor, you should either replace the rest of the hardware or return the old video card. Fortunately, diagnosing such phenomena is easier than other problems.

Download files

Windows 7 won't boot normally? Often, users say that they encounter black screens in the early stages of loading. They say "Bootmgr is missing". Next, you are asked to press Ctrl + Alt + Del to reboot the OS. Sometimes the user may encounter a regular black screen with no text. The cursor moves across the monitor when you move the mouse, but nothing more.

This error indicates that the boot file was corrupted while the computer was running. Bootmgr is a boot loader for Windows 7 and Windows 8. It is initially hidden from users. Removing it when formatting the hard drive is problematic. Often the cause of this error is viruses.

What to do in this case? Installing Windows 7 on your computer from scratch will help. This is the simplest solution. You can try to restore the operating system, but if this technique does not help, you will have to act decisively and radically.

Registers

Windows 7 won't load? A black screen, as we have already said, either indicates problems with the video card, or highlights failures of the Windows bootloader. Sometimes when you start your PC, the system registry is not read and loaded. This is an extremely important element.

As a rule, an error is easily identified - a corresponding warning appears on the computer screen. In addition, correcting the situation will be easier than it seems. The computer will launch the recovery wizard. By following his instructions, the user will be able to fix the problem. Not always, but often this technique helps.

Recovery Wizard

But the user will not always be able to use the automatic operating system recovery wizard. Sometimes you have to call him yourself. In addition, if Windows 7 does not boot, everyone has the right to use a set of OS recovery tools.

To launch the corresponding menu, you must:

  1. To restart a computer.
  2. At the PC boot stage, press "F8" several times.
  3. Select "Troubleshoot your computer."
  4. Enter the access password.
  5. Click on "Startup Repair".
  6. After completing the operation, reboot the PC.

Using the menu called up, you can perform a system rollback. To do this, just select There is nothing incomprehensible or difficult about this.

Safe mode

Sometimes Windows 7 does not boot in normal mode. In this case, you will have to restore the OS. It is advisable to do this using Windows 7 Secure Boot. In addition, this mode helps restore drivers and clean the operating system.

To use Secure Boot you will need:

  1. Turn on the computer.
  2. Click on "F8".
  3. Select "Safe Mode".

You can wait for the operating system to load. Shortcuts will appear on the screen on a black background. To restore the OS, just go to “Start” - “All Programs” - “Accessories” - “System Tools” - “Recovery”.

After a secure boot, the user will be able to use all Windows services. For example, the command line. It often helps get rid of some

"Blue Death"

Sometimes users are bothered by a blue screen when loading Windows 7. It's called the "blue screen of death". As we have already said, most often such an error occurs due to problems with RAM.

A blue background appears on the monitor display. It has specific error information written in white font. The user does not need most of the information. Just look at the type of error, as well as the “Technical Information” section. With their help you can understand what's going on.

Errors with the hard drive and/or its controller can be indicated by errors like:

  • stack_inpage_error;
  • data_inpage_error;
  • inaccessible_boot_device;
  • mode_exception_not_handled.

It is advisable to have a BIOS error reference book on hand. It contains a complete list of Blue Screen of Death errors. With its help, everyone will understand exactly what the problem is with downloading Windows 7. There is no need to install a new operating system. But how to bring your idea to life?

Reset BIOS

Russian Windows 7 won't load? A similar problem occurs when working with hacked software. By reinstalling it, the error will disappear.

As we have already said, the Blue Screen of Death indicates corruption in the BIOS. Resetting the settings will help correct the situation. You can do this:

  1. Get to the motherboard and press the special jumper.
  2. Remove the coin cell battery and insert it back. The corresponding element is located on the motherboard. It is recommended to completely replace the battery on your PC if there are BIOS problems.
  3. Turn on the computer, press the BIOS button ("F2", "F4", "Del" and so on - it all depends on the motherboard). Go to Exit and set the pointer to Load Setup Defaults, click on the "Enter" button. Save changes.

Ready! Now the "death screen" will no longer bother the user. But what to do if the operating system still does not boot.

File recovery

In some cases, Windows 7 will not load due to damaged system files. They can be restored manually. This technique works if automatic recovery does not produce results.

To perform a manual operation, the user must:

  1. Launch the command line in Windows 7. It is advisable to do this in safe mode.
  2. Write: sfc/scannow /offbootdir=c:\ /offwindir=c:\Windows.
  3. Click on "Enter".

You can wait for the computer to be scanned and the boot files to be restored. The operation usually takes a few minutes.

Re-creating a section

Is Windows 7 loading slowly? What to do if in the end this operating system does not start?

Didn't all the tips listed above help? Then you can try to recreate the boot sector. It is also recommended to rewrite the boot code.

This is done like this:

  1. Open a command prompt in safe mode on your computer.
  2. First enter bcdboot.exe C:\Windows and perform the operation.
  3. Write bootrec/fixnbr and bootrec/fixboot.
  4. Execute requests.
  5. To restart a computer.

Ready! Now is the time to check the loading of the operating system. It is possible that the problem will disappear.

Slow work

If the operating system is working in principle, the user can be offered the following acceleration methods:

  • disable startup programs;
  • scan the OS for viruses and remove all malicious files;
  • launch CCleaner and clean the PC registry;
  • clean the operating system of files and programs.

All this really helps. If the techniques are not effective, you will have to agree to reinstall Windows 7. Usually the idea requires an installation disk. In the BIOS, you need to set the hard drive to first place in the Boot section, and then, following the instructions on the screen, complete the installation.

Every computer user knows very well how frustrating it is when a program does not work. And if Windows doesn't start...
There can be a lot of reasons why Windows 7 won’t load, ranging from problems with installed software to hardware malfunction. Usually, if any of the computer parts are faulty, this can be heard during the initial testing of the computer components.

Surely, when you booted your computer, you heard a short beep coming not from the speakers, but from the built-in speaker in the system unit. This signal means that all computer components are working properly. If there is no signal, or if the signal is long or there are several of them, this indicates a malfunction of one of the components. That's why Windows won't load for you. You can read about what exactly these or other signals mean when loading.
But what to do if, judging by the signal, everything is fine with the “stuffing” of the computer, but the operating system still does not boot?

With such problems, the main thing is not to panic, but to calmly analyze the operation of the system. Remember which programs were installed and which were uninstalled during the last session. Let's look at everything in order. Let's start with, perhaps, the most “scary” thing - Windows 7 will not start.

There are many reasons for this behavior of the operating system - from banal errors in application programs to hardware faults. And, of course, we should not forget that this system from Microsoft, although it is head and shoulders above all their previous creations, nevertheless, sometimes behaves unpredictably.
If Windows 7 does not start, and after turning on the computer, a white message appears on a black background saying Disc Boot Failure, then it is quite possible that the reason lies in a dead battery that supports the settings.

Immediately after turning on the computer, press the Del button until we get to the BIOS screen. We are looking for the line First Boot Device (main boot device).

Solution: Check the boot queue (how to do this should be written in the instructions for your motherboard) and change it if necessary. If the system is on a hard drive, then the corresponding hard drive, etc. If the settings are lost without reason, it makes sense to replace the battery on the motherboard.

However, more often a problem like “Windows 7 won’t start” lies in the loose contacts of the interface cable. Sometimes it is enough to move the system unit a little so that the hard drive is no longer visible.

Solution: disconnect and reconnect the cable going to the boot device.

If the download continues and a list of actions appears, then you need to try using the “Load last known good configuration” menu item. You can also choose as an alternative. It also wouldn’t hurt to use one of the antivirus utilities to scan your computer for viruses in safe mode.


If the system boots like this, then the cause of the problem is some program installed during the last session. Perhaps this is where the problem lies (especially if the operating system loaded normally before, but crashed immediately after installation).
What to do in this case?
Try to enter safe mode the next time you boot your computer. If you succeed, first check your startup and remove all unnecessary programs from there. If you recently installed a program or piece of hardware and think it might be the problem, try uninstalling the program in Safe Mode or disabling the hardware and uninstalling the associated driver.

Sometimes Windows 7 boots to the system recovery screen. Moreover, there are no apparent reasons for this behavior. It is often solved by simply rebooting the computer, without any recovery.

Problems with system performance may be caused by a faulty RAM or hard drive. To determine them, you can use special programs that work from a pre-prepared LiveCD.

But, fortunately, such problems are less common than with applications. For example, users often ask why “Minecraft won’t start. Windows 7 works fine." Minecraft uses a virtual machine Java And OpenGL. Therefore, we install the latest version of Java and the latest video card drivers. It is also worth noting that there may be difficulties with launching from a Russian folder (the name must be in English).

Similar messages like “Terraria won’t start” are also common. Windows 7 works like a charm." This game is the twin brother of the above Minecraft. The difference is that it does not use Java, but the .

Solution: install this package (you can use a pack that includes versions from 2 to 4), install and Microsoft Visual C++ 2005 and higher.
When running on the new Windows 8, problems may arise, since the system requires independent connection of the Net Framework (via “installing programs - enabling Windows components”).

As you can see, there are several reasons why Windows 7 does not load, so the ways to solve this problem may be different. In advanced cases, it may be necessary to reinstall the system, but usually it is possible to solve the problem in other ways.

That's all. Thank you for reading the article. I hope it was useful to you.

During just one Windows startup, the system runs many processes. Accordingly, when Windows OS does not boot, there may be several reasons for this. Below we will look at what can cause an error when starting Windows, and also fix the problem that has arisen.

Hardware problems.

We will not dwell in detail on the inoperability of the equipment, because... On your own and without the necessary skills, determining which equipment is broken is quite difficult. The following are some types of errors that may indicate that the problem is related to the hardware:

1. A repeated failure of the same driver may indicate the inoperability of the device, which is controlled by this driver.

2. Errors that are accompanied by a blue screen may indicate problems with the device’s RAM.

3. Various artifacts or a completely missing image say.

5. If during boot, this may indicate a malfunction of the power supply, motherboard, and sometimes other hardware.

Problems with corrupted boot files.

If during the first stages of Windows boot the system detects the absence of important boot files, a message may appear on the screen "BOOTMGR is missing". In addition, this problem may be accompanied by other messages or a complete absence of any messages (black screen with or without a cursor).

Bootmgr – an operating system loader that is not available to ordinary users. However, users can easily format it by booting from external media. After this, the operating system will not boot.

Registry problems.

If the problem is caused by a damaged registry, Windows may not even start loading. Instead, a message will be displayed on the screen that the system has crashed, and it will also prompt you to use the recovery environment.

Quite often, restoring helps to load the registry from a backup and fix the Windows startup problem.

However, recovery may not always be successful, because the system may not have the necessary backup copies.

Troubleshooting Windows startup problems.

Recovery environment.

It is much more convenient to resume starting Windows 7 than Windows XP, which did not have time to receive the recovery environment. When installing Windows, this environment is installed on the hard drive, has a separate partition, and a separate bootloader. This is why the recovery environment is not affected by the problems that Windows faces.

To launch the recovery environment, press F8 and select from all Windows boot options "Troubleshooting your computer" .

Next, to get into the recovery environment, the system will ask you to enter a password. If you have forgotten your password or do not have administrator rights, you will have to launch the recovery environment from the installation disk.

1. Startup recovery.

This point is worth resorting to if you do not know the exact reason for Windows not starting.

Select an item "Startup Recovery" . The system will scan and fix the problems found.

2. System recovery.

This method can be used if Windows stops loading after installing a program, infecting the computer with viruses, or making changes to the registry.

The parameter will help resolve the problem "System Restore" , but only if the restore points were saved.

The principle of operation is quite simple: you select the desired restore point, which dates back to the time when there were no problems with Windows. The system rollback will begin, after which Windows will boot normally.

3. Restore the system image.

Used when there are no backups saved on the computer, but you have a recovery point saved on removable media.

Select an item "System Image Restore" , and then connect to the computer removable media that contains the system image archive. Next, follow the instructions of the Recovery Wizard.

4. Manual registry restoration.

Used when the above instructions did not resolve the problem. On Windows, the registry is backed up every 10 days, so you can try downloading the latest working backup yourself.

From the list of available options, select "Command line" .

Type the following command into it and press Enter:

The standard Notepad program will launch. Select menu in the program header “File” – “Open” .

Go to directory C:\Windows\System32\config

At the bottom of the window in the column "File Type" change the parameter to "All files" to see the full contents of this folder.

The following list of files applies to the current registry:

Default, Sam, System, Security, Software(no extension)

Each of these files must be renamed or the extension added to them .old. See the screenshot below for an example.

In folder "config" open the folder "RegBack" . This contains registry backups. Copy them one by one to a folder "config" .

Go back to the window "Recovery Options" and at the very bottom select the button. If the problem is due to a problem in the registry, then Windows will start normally.

5. File recovery.

Windows has a wonderful built-in utility that perfectly restores protected Windows files.

On the menu "Recovery Options" select item "Command line" and write the following command in it:

/scannow /offbootdir=C:\ /offwindir=C:\Windows

The “scannow” command will start scanning the system, “offbootdir” indicates the system drive letter, “offwindir” leads to the “Windows” folder.

Please note that the drive letters in the recovery environment may not match those seen when booting Windows normally. Therefore, before you start scanning, be sure to launch Notepad (this process is described above) and check the system drive letter in Explorer.

6. Manual file recovery.

If the methods described above do not bring the desired result, you should try to manually restore boot files, as well as overwrite the master boot record of the HDD.

To do this, open the menu “Recovery options” – “Command line” and run the following command, having previously specified the partition letter through Notepad:

Now run the following two commands one by one:

After that, proceed to restart Windows.

These methods help resolve many Windows boot errors. If the above tips did not help you, your only option is to get help from a service center - the problem may lie in the hardware.

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 back up and running.

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 applied 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!
