Good afternoon everyone!
Despite the fact that each new Windows version becomes more and more stable and reliable - all the same, unpleasant incidents often happen to it...
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. Often you can see an error message, its code, description (and knowing this information, it will be easier to find and diagnose the cause).
For example, the photo below shows one of typical mistakes"Disk boot failure..." (error related to bootable media, according to her decision, 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 point is that when certain settings The computer's BIOS can "search" for boot entries on the same flash drive, and not finding them, it simply does not proceed to boot Windows from 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 HDD- it may happen that incorrect settings will be indicated in the BOOT section (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 Windows boot within 5-10 minutes (some of them, by the way, think that it is frozen and rush to restart the PC again and wait for 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.

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 regular USB port (makes work much easier).
Method 2
That's all for now...

Very often, computer users encounter a problem when the Windows 7 operating system refuses to start. However, many of them do not understand why this can happen. In this case, it would not hurt to know the main and common reasons why this can happen, as well as the errors that occur with this problem and methods for eliminating them.
Error Disk boot failure, insert system disk and press Enter
This is the most common mistake, which appears after starting the computer. As a rule, instead of starting the operating system, it displays Disk error Boot fail. This may indicate that, according to the operating system, the disk from which they wanted to launch it is not the system one. This problem may occur due to various reasons, among which are the most common.
It very often happens that a disk is inserted into the drive or a USB drive is connected to the PC, and the BIOS is configured so that it sets this media to boot by default. This leads to the operating system not starting. In this case, you should try disconnecting everything 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 boot order is set incorrectly in the BIOS. In this case, the instructions from the method above will not be able to help. Even if the computer starts up normally in the morning and then stops in the evening, you need to check this option, since the BIOS settings may be lost. 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 verify that the hard drive is detected by the BIOS.
In addition, if the operating system sees the hard drive, you can resort to system startup recovery tools. This will be discussed a little below. If the system cannot detect the hard drive, if possible, you can try disconnecting the hard drive and reconnecting it. In this case, you should pay attention to the connection of the hard drive to the motherboard.
In addition, such an error may occur for other reasons, including problems with the hard drive itself, the presence of viruses in the system, and much more. Be that as it may, it is recommended to check all the methods described above. If nothing helps, then there is another solution to the problem, which is suitable for almost all cases when the “seven” does not want to start.
Error BOOTMGR is missing
This error can also appear when the operating system of the seventh version refuses to start. The message BOOTMGR is missing appears on a black screen. This error can appear for various reasons, including the activity of viruses, incorrect actions of the user himself, which led to a change in the boot record of the hard drive, or some mechanical problems in the hard drive. Options for solving this problem can be searched on the Internet.
Error NTLDR is missing. Press Ctrl + Alt + Del to restart
This error manifests itself in almost the same way as the one described above. At the same time, the methods for eliminating it are slightly different from the previous one. To fix this problem, you can use special instructions that are easy to find on the Internet.
Windows 7 boots but only displays a black screen and mouse cursor
If, after starting the computer, the operating system desktop is not displayed on the screen and there is no “Start” menu, but only a black screen with a mouse cursor, then this problem can be solved quite simply. Very often, this problem occurs after removing the virus using antivirus utilities or yourself. As a rule, not all changes that the malware caused were corrected, which led to the appearance of a black screen. This error can be fixed quite simply, as can be found on various forums related to 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 some other errors, when the PC starts, the system recovery screen will be displayed, with which you can try to resume starting the operating system.
However, if such a screen does not appear, then you can press F8 after the BIOS has loaded, but the operating system has not yet started loading. As a result, a menu will appear on the screen with the item “Troubleshooting PC”, which must be clicked.
After this, a notification will pop up informing you that the download of operating system files has begun. Then you will be prompted to set the language, where you need to specify Russian. Next you need to log in to your account. To do this, it is better to use an administrator account. If a password has not been set, then it can be left blank.
After these manipulations, the operating system recovery window will open, in which you can activate automatic search and eliminating problems that prevent the system from starting normally. To do this, you need to click on a special link.
Once all problems have been identified, the application automatic mode will eliminate all errors found that prevented Windows from starting. It happens that the utility does not find any problems.
In this case, you can resort to using the OS recovery function. If the problem with starting the operating system appeared after updating drivers or something else, this action may help. In principle, it is clear how this procedure can quickly resolve the problem associated with updating operating system components.
In general, these are almost all the main problems that can arise when the system refuses to start. If none of the above helps, then you should contact a specialized computer repair company.
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 problems arise during Windows launch 7 Press F8 to open a menu with a list of additional computer startup options.
- 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, run command line from the OS Resume 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 devices installed on your computer long-term storage information on the presence of OSes installed on them that are compatible with the “seven”, and will allow you to add them to the download list.
And in the very last 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 ones hard disks, 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 the 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 functionality. operating system.
But the Windows 7 automatic recovery tool is not always effective and, for example, in the absence backup copy 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”.
- Confirm execution given operation, 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.

Users often encounter a problem when they cannot boot a computer or laptop running on Windows 7 OS not only in normal mode, but also in safe mode. This problem can be caused by a variety of reasons. System and hardware failures often lead to the fact that the operating system cannot boot or spontaneously goes into reboot, or after turning on the PC appears blue screen of death. What to do if Windows 7 does not enter safe mode, how to solve this problem and restore your PC's functionality. In this article we will try to solve these problems.
What is safe mode and why is it needed?
Safe mode in Windows OS ( Safe Mode) - a special diagnostic mode of operation of the operating system, which is used to identify and eliminate errors in the OS registry. If you run Safe Mode, unnecessary system components will be disabled by default. In other words, when you turn on a computer or laptop with this option, only the most necessary system components of the device and important drivers will be loaded.
If the PC on which Windows 7 is installed encounters any malfunctions after turning it on, you can try starting the device through safe mode with a basic set of services. After the system boots into Safe Mode, the user can perform the same actions as during normal Windows startup 7.
This download method will help detect the presence of virus, adware, and spyware in the system that interfere with the normal functioning of a desktop computer or laptop.
If Windows 7 only boots into safe mode immediately after turning on the PC, this indicates that there is a problem that is preventing the operating system from starting normally. In this case, the reason, as a rule, lies in recently installed software.
To solve the problem, you can try to restore the system. To do this, go to “ Start» - « Control Panel» - « System Restore».
But what to do if a device with Windows 7 not only does not enter safe mode, but does not want to start even in normal mode. Let's try to understand this issue.
Reasons why Windows 7 cannot boot into Safe Mode
As already noted, most often the need to enter safe mode on any version of Windows OS, including the “seven”, is due to the need to scan and check the PC for viruses and the presence of virus software. Of course, if the computer does not turn on in normal mode.
Even though Windows 7 is this moment occupies a leading position among all operating systems presented, it cannot be said that this version The OS is the standard of absolute quality. Unfortunately, Windows 7 has many of its own bugs and shortcomings, which affect the stability of your device. Especially if you neglect to install licensed software.
If the safe one does not turn on Windows mode 7, this problem may be caused by:
- the presence of viral, potentially dangerous software (viral advertising, software);
- hardware power failure;
- file system damage;
- technical problems.
As a rule, if Windows 7 does not want to turn on in safe mode, according to experts, this problem lies in the presence of “evil” viruses in the registry due to the installation of applications and software from unverified, dubious sources. Most likely, under the influence of spyware modified programs in system files The registry branches that are responsible for entering safe mode have been removed.
How to boot your PC in safe mode
Everyone knows that you can boot your PC in safe mode by pressing the F8 key immediately after turning on the PC. But pressing this key does not always bring up the safe mode menu, which can be caused by a number of problems.
If Windows 7 does not boot in safe mode, there are several ways to fix this problem:
- reinstalling the OS;
- changing the system configuration;
- using special utility AVZ.
The most radical method is complete OS reinstallation. The only thing worth noting is that this option only suitable if you have it on hand removable media, a distribution kit with this version of the operating system. That is, the one that was already installed on the PC. This will require " System restore point" The most recently saved system restore points will open in a special window when this feature is activated.
It is worth noting that if the system has important files and it is not possible to install the system with installation disk, this option cannot be called the best solution Problems.
Sometimes, if turning on the computer is impossible in Safe Mode, you can perform the so-called “knurling” ( system rollback) - a process that is identical to a complete reinstallation of the OS, allowing you to save all previously installed important programs, applications, software. If necessary, you can do backup data, important information on PC.
If you completely reinstall the system, you can restore lost registry data using a utility application, namely System Restore. But you need to remember that using this console is not effective in all cases. To ensure that the OS boot option is restored in Safe Mode, we will need a recovery REG file that is fully compliant with this OS.
The best option that will help if Windows 7 does not want to boot or start in safe mode is AVZ utility, which can be downloaded without any problems from the official web portal. In addition to restoring PC functionality this program will help eliminate various threats, malware on your laptop system or personal computer. To do this, you need to perform the following sequence of actions:
To boot Windows 7 in safe mode, you can also try change OS configuration. At the same time, the main thing is to avoid mistakes in your actions by adhering to the following sequence:
- Go to the menu " Start", click " Execute».
- In field " Open"We enter the msconfig command and press the OK button. After which you can see the window that appears “ system configuration", as well as other active tabs at the top. ", after which the line " Safe mode».
- Check the box " Safe mode", confirm the action by pressing OK.
Now you need to restart your PC and check the functioning of safe mode. To do this, during the reboot process, at the very beginning of the system boot, press ". Now you need to re-enter " system configuration» - «» - « Safe mode" Uncheck the box next to “ Safe mode", click OK.
As you can see, if Windows 7 does not boot in safe mode, you can solve this problem using several of the methods presented above. The main thing is to adhere to the established sequence. If the system continues to be unstable, the computer does not boot in safe and normal mode when turned on, the system reboots spontaneously, perhaps the main reason is technical malfunctions. In this case, qualified specialists will help you troubleshoot the problem after conducting a comprehensive diagnosis of your laptop or PC.

Often, when installing a clean Windows 7, users are faced with a missing media driver. Without fulfilling this requirement, the installation process cannot be continued. This may be due to certain errors or the actual need to install software. In this article we will look at ways to solve this issue.
The situation under consideration is very non-standard and its possible sources can be software and hardware. Let's look at the main faults and methods for eliminating them. It should be noted right away that “crooked” operating system builds are usually to blame, and in rare cases, a notification that appears may indicate non-obvious problems such as a malfunctioning random access memory, which damages files when copied.
Reason 1: Low-quality Windows distribution
Custom Windows builds, which can be found on any torrent tracker, often have a lot of shortcomings and errors due to the unprofessionalism of their authors. Old builds may also be incompatible with new hardware from NVIDIA, so the easiest solution is to choose a different OS distribution.
Sometimes media drivers are deliberately removed from the system image. If a message appears about a missing driver, simply connect the media with the factory drivers of your computer. Actually, this is exactly what is written in the text of the notification itself. Since the installation process will be in RAM, you can easily take out a disk/flash drive with Windows and install software via button "Review" from another CD/USB, and then reinsert the media with the OS distribution.
If the problem is not resolved, try the following options.
Reason 2: Incorrectly working media
It is possible that one of these points negatively affected the installation:
In addition to everything, we can advise you to choose a program for recording a system image that is different from the one you used for the first time.
Reason 3: Problematic hard drive
Due to the HDD, you may also be asked to install drivers. There are at least 3 options for what to do:
Reason 4: Iron incompatibility
Less commonly described symptoms occur due to the combination of old and new components. A similar picture arises when using components from various manufacturers, for example, AMD and NVIDIA. The only solution is the competent selection of compatible hardware.
Reason 5: Problems with the drive or USB connector
There are several points here that can become a stumbling point when trying to install Windows 7. Let's go from simple to complex:
USB connection via interface 2.0 instead of 3.0
If your PC or laptop has USB 3.0 through which the operating system is installed, it may be this connection that causes the message that prevents further completion of the procedure. In this case, the installer actually asks for a driver that is not included by default. Reconnecting the flash drive to port 2.0 solves the problem. It's easy to distinguish them - the 3.0 connector is half blue.
Downloading the driver for USB 3.0 to a flash drive from Windows image 7
If there is no 2.0 connector, you will need to download a driver for USB 3.0 from the manufacturer’s website motherboard or laptop. This can be done according to the instructions for downloading the SATA driver described above, in "Reason 3". The difference is that you don't need to download "SATA", A "Chipset".
As a last resort, you can search for a driver for the chipset on the Intel or AMD website, depending on the component installed on your board.
PC component failure
The most unpleasant thing is the complete or partial failure of the CD/DVD drive or USB interface. The situation can only be saved by replacing faulty devices.
