Hello, dear readers, Trishkin Denis is in touch.
working long time at the computer, many users are faced with a situation where they simply do not load Windows 7. Moreover, each individual case has its own manifestations. To understand this topic in detail, I will try to consider the most common options. Despite the fact that there are many of them, there is still a certain classification.
There are many options due to which the operating system refuses to work in its usual mode, and a black screen appears:
problems with RAM;
incorrect installation of updates.
hard drive problems
Incorrect device boot queue set;
a flash drive is inserted into the USB port;
The system only starts in safe mode( )
Sometimes users may encounter a situation where Windows only boots in safe mode. First you need to try to remember what could be the problem of the malfunction. Often the reason is the installation of a new application. In addition, the group of the most popular reasons can safely include transitions by advertising banners on the Internet, changing hardware settings, connecting new devices.
To solve the problem, you need to try to return everything as it was before the malfunction occurred. If the problem appeared after installing the program, the latter must be removed:
If problems arose as a result of connecting the device, we are doing other steps. I recommend referring to this method even when blue screen death just like that, without any hardware or software changes.
So, let's do the following:
You can familiarize yourself with the problems for which the death screen appears in detail by going to.
Hanging on a hello( )
Often, users can observe a situation where Windows does not boot beyond the welcome. That is, they see the inscription: "", and this is where it all ends. As with any problem, there can be many reasons. We will highlight only a few of the most common.
If problems appeared after clicking on an unverified link or as a result of installing a dubious software, it is advisable to use the help of antiviruses. To do this, you need to boot into "" using the button " F8". And run the appropriate solution. At this time, you can complete the work yourself suspicious programs in " Task Manager».
Windows may hang at the logo as a result of insufficient hardware thermal management. This may be preceded by non-working coolers, dried thermal paste, great amount dust. To establish this reason, it is enough to use one of the utilities that show the current temperature conditions. It is necessary to compare the readings with the data from the documentation. If they exceed those written in the passport, it is urgent to clean and, if necessary, replace individual components.
This element can also overheat. In addition, problems appear as a result of mechanical damage component. To establish the exact cause, some tests need to be done. You can read more.
If, as a result, it turned out that the malfunctions appear due to overheating, it is necessary to use appropriate heat sinks. With them, users can significantly reduce the risk of running out of RAM.
In some cases, only replacement helps. the main problem is that factory defects can appear even several months after active use.
Sometimes malfunctions operating system directly related to the work of the hard drive. It can be both logical, electronic, and mechanical errors. Often a harbinger of problems is unusual sounds emanating from the corresponding equipment. How to check and other information can be read in.
Updates( )
In some cases, the operating system refuses to work after the update. The main thing to remember is whether the corresponding screen appeared during the last reboot or shutdown of the system. If so, you need to try to restore performance windows way rollback to previous versions. This can be done from a disk on which there are files for installing the operating system. You can also try to boot from a flash drive.
Sometimes it even saves the option " Loading the configuration with the last working parameters”, which can be selected by pressing “ F8» during the start of the equipment.
If you are not sure that the problem can be solved exclusively reinstalling Windows, it is worth taking advantage of other opportunities to restore performance. You can find out in detail from.
As you can see, there are many reasons why the operating system from Microsoft may not want to boot. Moreover, each of them is solved by its own tools.
Hope you can find the right one for you. Subscribe and tell others about my blog.
We will fix errors in Windows 10. But we will have to do about the same in Windows XP, 7 and 8. In Windows 7 and later, developers have improved the recovery system after startup problems. In older versions of the system, serious errors often have to be solved by reinstallation.
Disable Peripherals
Try to remember what changes you recently made to the system: whether you installed new devices, devices, or switched something. Perhaps the problem is in one of the hardware components. Try to disable:
- USB drives.
- Card readers.
- Printers.
- Scanners.
- Cameras.
- All other external devices.
If this does not help, unplug your keyboard and mouse: you need to exclude everything possible sources malfunctions.
Also, the reason may be internal components, for example RAM. In a desktop PC, you can check the performance of the RAM by connecting the brackets one by one.
Check nutrition
If the computer does not turn on at all, pay attention to the power cable and sockets. Don't forget the power switch on the back of the desktop case.
If everything works at this level, but the computer still does not turn on, then most likely the problem is in the power supply, which you are unlikely to be able to fix yourself: you will have to replace or repair it by a specialist.
It is possible that the computer turns on, but only for a short time. It's the same problem with the power supply.
Set up a disk to boot the system
Errors may appear during startup: An operating system wasn't found. Try disconnecting any drives that don't contain an operating system. Press Ctrl+Alt+Del to restart or boot failure. Reboot and Select Proper boot device or Insert Boot Media in selected Boot device.
The BIOS or UEFI settings can be set to boot from external device or another logical partition, and not from the system drive. You can restore the default settings like this:
- To restart a computer.
- Immediately after restart, press system key, for example F2. This may be another key: usually during system boot, it can be found at the bottom of the screen with the logo of the laptop manufacturer or motherboard.
- In the settings, set the desired disk to the first place in the boot.
- Select the Save and Exit option to save your changes.
If the above did not help, you will have to restore the system bootloader. To do this, you will need a bootable USB flash drive or recovery disk with a system that is suitable in terms of bit depth. How to do bootable flash drive or disk, read Lifehacker about installing Windows.
Start the system from a USB flash drive or disk by selecting desired option in the boot menu. In the menu that opens Windows installation select "System Restore".
From the recovery menu select "Troubleshooting" → " Extra options» → «Startup Repair». After that, the system will try to automatically fix the bootloader. In most cases, it solves the problem.
The same can be done manually through the command line, but it is better to choose automatic option so as not to aggravate the situation.
If this method did not help, the problem is probably in the hardware: the hard drive is damaged.
From the recovery menu, select Troubleshoot → Advanced Options → Command Prompt.
IN command line you need to enter the commands one by one: diskpart → list volume (be sure to remember the name of the disk with Windows) → exit.
To check the drive for errors and corruption, type chkdsk X: /r (where X is the name of the Windows drive). The check usually takes a long time, you have to wait.
Start Windows in Safe Mode
Because of sudden shutdown computer during the installation of operating system updates, cleaning from viruses and unnecessary entries in the registry, or through the fault of utilities to speed up Windows work system files may be corrupted. In this case, the blue screen of death will appear when the system boots.
Try to start Windows in safe mode without loading drivers and programs in autorun. If the computer works in this mode, you will have to remove the drivers, perform a system rollback and scan for viruses.
If you have restore points, this problem is quite easy to solve. You just need to roll back to the previous stable configuration.
Reinstall system files
The steps above may not help. Then you have to drop windows settings and reinstall the system with saving the files. Unfortunately, all programs will need to be installed again.
In the recovery environment, select Troubleshoot → Reset this PC → Keep my files → Reset.
The system will roll back to the original settings.
There are at least three common mistakes that lead to problems with Windows boot 7. The system, when errors occur, displays on the monitor screen short message, which indicates the problem. It is these small instructions that we will be guided by when solving the problems that have arisen.
Perhaps the most common mistake is Disk boot failure, insert system disk and press Enter
It is characterized by the following situation: you turn on the computer, but instead of the usual loading of the operating Windows systems 7, this inscription is displayed to you. It means that the system recognized the disk from which it starts not as a system one, that is, by Windows opinion 7 system files required to run it on this disk is not. This can be caused by various reasons. Let's take a look at the most common ones.
Possible variant. A disc has been inserted into the DVD-ROM or a flash drive has been connected and your BIOS is configured to default to one of these media. As a result, the system cannot find the files it needs to run on a USB flash drive or DVD disc and reports an error.
Elimination. Try turning everything off external drives: phones, memory cards, flash drives and external drives. After that, the computer should be turned on again. Most likely, the system will start correctly this time.
It may be that the recommendations provided above will not help. In this case, you need, firstly, in the BIOS settings, set your default startup device. system disk. And secondly, you should make sure that the BIOS detects your system disk at all. It may be that he is out of order.
If the system correctly displays the system disk, it is in your power to use. We will touch on this a little later, at the end of the article.
If the system does not display your main HDD, you can try unplugging it and plugging it back in, or into a nearby jack if it's present.
Other problems can also lead to this error, for example, viruses, etc. In any case, it is best to first check the methods that we mentioned. Most likely they will work. If not, then feel free to ask at the end of the article in which we indicated step-by-step elimination Windows problems 7 using the utility.
BOOTMGR error is missing
Due to this error, you will also not be able to start Windows 7 correctly - black screen message - BOOTMGR is missing. This problem can also be caused by various reasons, including all kinds of viruses. She can be called erroneous actions inexperienced user who accidentally changed the boot record hard disk. Also physical problems HDDs are often the cause of this error.
Elimination. Check if the hard drive itself on which the system is installed is working. Seek help from the Windows 7 Recovery Environment, which is discussed below.
NTLDR is missing error. Press Ctrl + Alt + Del to restart
This problem manifests itself in almost the same way as the previous one. To fix it, you should also use the troubleshooting environment.
When starting Windows 7, the user observes only a black screen and a mouse pointer
If the usual desktop with the start menu does not load when the system is started, and all we can see is the mouse pointer, then everything is not so difficult and in the vast majority of cases it is easy to fix. Very often this error occurs if you use antivirus program got rid of some serious virus that had already managed to make trouble and these same troubles were not fully corrected by the antivirus program.
Elimination. Restart your computer and as soon as the mouse pointer appears, press Ctrl + Alt + Del. Task Manager will immediately appear.
In it, you need to select the "File" menu in which to create new task(execute). A dialog box will appear, in it you should enter the regedit command and press Enter. This will launch the Windows 7 System Registry Editor.
We will need to view the sections in the editor:
HKEY_LOCAL_MACHINE/Software/Microsoft/Windows NT/Current Version/Winlogon/
- HKEY_CURRENT_USER/Software/Microsoft/Windows NT/Current Version/Winlogon/
Now you need to edit the value Shell.
With the first section, make sure the Shell option is set to Explorer.exe If not, then install it yourself. In the second case, you need to go into the section and see: if there is a Shell entry in it, then it must be deleted from there. Now it remains to close the registry window and simply restart the computer. Everything should fall into place.
And so, everything that we could not eliminate on our own, we eliminate with the help of standard utilities systems
In most cases, if there are problems when starting the operating system, we can see the Windows 7 recovery screen. It is he who will help us in restoring the system startup. If the recovery screen does not appear on its own, then the next time the system is rebooted, we can call it on our own by pressing the key F8. Select "Computer Troubleshooting" from the menu
As soon as problems are found, they will be automatically fixed by the utility. But it may also be that system utility will not find any problems. Then we can use the system restore functions, this often helps if problems with starting the system are due to installing a system update or third-party software. Since the interface of the service is intuitive, it will not be difficult to solve the problem.
That's all. In 99% of cases, you will be able to solve one of the problems that causes the error to start Windows 7. Otherwise, the problem is in the hardware of your computer. You can also if you are sure that everything is in order with the iron. Good luck!
Very often, computer users are faced with a problem when the Windows 7 operating system refuses to start. However, many of them do not understand why this can happen.

This problem may occur due to different reasons among which are the most common.
It often happens that a disk is inserted into the drive or a USB drive is connected to the PC, the BIOS is configured to set this media to boot by default. This leads to the fact that the operating system does not start. In this case, you should try to disconnect all third-party drives such as SD memory, flash drives, smartphones, etc. You also need to remove the disc from the drive, and then try to start the computer again.
Perhaps this time the operating system will start.
In addition, the problem may occur when the wrong boot order is set in the BIOS. In this case, the instructions from the method above will not be able to help. Even in the case when the computer started normally in the morning and stopped in the evening, you need to check this option, since the BIOS settings may go astray. This can be affected by a dead battery on the motherboard or power outages, as well as static discharges. When checking the settings, you need to check that the hard drive is detected by the BIOS.
In addition, if the operating system sees the hard drive, you can resort to using the system startup recovery tools. This will be discussed a little below. In the case when the system cannot detect the hard drive, if possible, you can try to disconnect the hard drive and reconnect it. At the same time, attention should be paid to the connection hard drive with mother.
In addition, such an error can occur for other reasons, among which are problems with the hard drive itself, the presence of viruses in the system, and much more.

Very often, this problem occurs after removing the virus using antivirus utilities or on your own. As a rule, not all the changes that the malware caused were fixed, which led to the appearance of a black screen. This error is fixed quite simply, which can be found on various forums regarding this problem.
Troubleshooting Windows 7 Startup Errors Using Integrated Utilities
In some cases, when the system refuses to start due to changes in the hardware configuration, incorrect shutdown of the PC, or any other errors, when the PC starts, the system recovery screen will be displayed, with which you can try to restart the operating system.
However, if such a screen does not appear, then you can press F8 after the BIOS has loaded, but the OS has not yet started loading. As a result, a menu will appear on the screen with the item “PC Troubleshooting”, which must be clicked.
After that, a notification will pop up, which will inform you that the download of OS files has begun. Then you will be prompted to install the language, where you need to specify Russian.

In general, these are almost all the main problems that can occur when the system fails to start. If none of the above helped, then you should contact a specialized computer repair company.
It is not always possible to immediately determine the cause of a particular problem in the computer. This also applies to situations when Windows 7 does not load. Even if such a problem has arisen, then do not despair. First, review the code or description of the error, and then try one of the suggested fixes.
Possible problems
In fact, there are a lot of errors that prevent the system from booting. All of them can be divided into two groups. The first includes those in which it is possible to start safe mode or the option to restore the previous configuration. And the second group includes problems in which the PC does not go beyond the boot screen.
There are also different ways to fix them. In the first case, it is enough to log in as a backup or primary user in safe mode, immediately delete extra element or perform a restore. In the second, you will need a clean, BIOS setup or rollback from Live CD. Let's deal with the problems that occur most often.
Option 1: Backup login possible
To begin with, it is worth checking whether it is possible backup entrance into the system when Windows 7 does not start. To do this, when you turn on the computer, you need to enter the boot mode selection menu. It will open automatically if you restart your PC several times.
Management is made by arrows on the keyboard. Select and then press Enter. If the action helped, then there will be no further failure, the computer will continue stable work. Otherwise, enable the option « Safe mode» , then run the rollback procedure according to the first method from our article: .
In short, open the menu "Start", click on the search bar, enter "recovery" and start the second element from the top. 
Then follow the instructions on the screen. At the end, restart your PC.
Note: in the boot option selection menu, the mouse should not work. But there may be problems with the functioning of the keyboard. The fact is that the drivers forUSB devices are loaded during subsequent startup steps. In this case, the solution is to connect the keyboard withPS/2 connector. You can also use a special adapter, they are very cheap.
Option 2: Disk boot failure
Why won't Windows 7 start with a Disk boot failure error? The essence of this failure is that the computer does not see boot files on the specified medium. This may be due to a violation boot priority(device loading order), as well as damage to important data.
In any case, first you need to go into the BIOS. To do this, when starting the computer, repeatedly press Delete key or F2. If this does not help, then look at the text on the title image when you turn on the PC. There need a point EnterSETUP. A specific key is indicated next to it, press it.
BIOS versions may vary depending on motherboard model as well as firmware. To get started, find the item BOOT. It is located either on the main screen or in the section AdvancedSettings. IN Bootpriority HDD or SSD should be in the first place. 
If this is not the case, then change the boot order to the desired one. The location of the rest of the elements does not matter.
What to do in the case when everything is set correctly, but the error still occurs. Unfortunately, in this situation, the problem is related to system data corruption. To get started, try Windows recovery 7. Does not help - go to the last paragraph of the article.
Option 3: BOOTMGR is missing error
Option 4: Other problems
If none of the listed options is suitable for solving your problem, then the system cannot be restored. In this case, a complete reinstallation is required. But, most often, important data is stored on users' computers that we would not want to lose. Therefore, it is advisable to reserve them.
Such services are always provided by computer masters, but there is not always time or opportunity to visit them. You can do all the steps yourself, but you will need a second computer or laptop that is in working condition.
The essence of the method is to boot via Live CD. In this case, the PC does not start from the hard disk on which the system is damaged, but from removable media with the emergency installed. windows way 7.
You cannot download a Live CD from the official Microsoft website, so look for it on third-party resources. The recording process is no different. It is best to use UltraISO. 
When you are logged in under the "live image", transfer all the data to any removable media and then reinstall Windows 7.
