The causes and solutions to the problem of the inability to start the OS are determined by error messages or their absence. The main situations are listed below.
Error disc boot failure Insert system disc and press Enter
This least critical error and it is the easiest to solve. It is caused by the fact that the system does not detect boot disk due to the boot sequence settings in the BIOS. Enough for a start remove the CD from the drive and disconnect devices such as flash drives, card readers, turn off external hard disks, others USB drives. To restart a computer. If the system does not boot or you want to completely eliminate the reasons, you need to reboot again and enter the BIOS.
You will need to fix the download queue. To do this, you do not need to know the computer or open its case. You must follow the PC manufacturer's instructions or motherboard. Usually needed immediately press the Del key as soon as the computer turns on. A menu will open in which you need to set correct order.
If after this the system does not want to start, then you need to use installation disk Windows. Put it in the drive and reboot. A window will appear with a choice of keyboards and languages. Click the cursor on the desired one. Proceed like this:
If the OS does not see the hard drive at all, then you need to check its connection with motherboard. This is appropriate if you do not have a warranty on your computer. Otherwise, the check is done in the workshop.
Error Bootmgr is missing
It is caused by an incorrect modification of the boot record. hard drive. There can be many reasons. Her viruses damage or unthought-out user actions, work different programs. But the most dangerous reason is physical damage to the media, as it can lead to the loss of important data.
In this case you need check disk special utility. It is most convenient to use Victoria or MHDD products. You need to do this:
- Download image You can download the boot disk from the official website;
- Write down it on CD;
- Load up from CD;
- Check disk.
If bad sectors highlighted in red are detected, you should immediately copy important information to external media. Next, solve the problem with the device.
If no damage is detected, proceed as described in the previous paragraph. You can also enter command line mode and run the commands bootrec.exe /fixmbr And bootrec.exe /fixroot by booting from the installation disk.
Ntldr is missing
The message appears after an incorrect shutdown of the PC due to viruses or changes boot sector. In this case it is necessary find ntldr files and file ntdetect.com. They can be taken from other computers in the \i386 folder or from Live cds.
Then the following work is done:
- Specified files copied to the root of the system disk;
- Computer I'll downloadandseems from the installation disk;
- When prompted to launch the recovery console with the R key, the user clicks on it;
- By using cd c commands: a transition is being made to system partition hard drive;
- The following commands are executed fixboot And fixmbr. The first will create the boot sector, and the second will copy the mentioned objects.
- If the system partition is inactive, it is activated using programs for working with hard disk partitions, then you need to check the paths to the operating system specified in the boot.ini file.
Loading stuck when black screen and mouse pointer appears
This usually occurs as a result of a virus and its incorrect removal. For example, a ransomware virus.
Then give the PC the following commands:
- When stuck, press Win + R;
- A window will pop up Execute;
- Print regedit;
The Registry Editor will appear. Look for lines HKEY_LOCAL_MACHINE/Software/Microsoft/Windows NT/Current Version/Winlogon/ And HKEY_CURRENT_USER/Software/Microsoft/Windows NT/Current Version/Winlogon/.
Having found the parameter in them shell, change its value to explorer.exe.
It happens that boot problems appear when you change the PC configuration. Then the recovery screen will appear on its own or you need to press F8 and select troubleshooting.
Windows 10 won't start
The new OS may refuse to work such reasons;
- Error when updating;
- Black screen while loading;
- Incorrect operation Internet connection devices;
- Crashes when exiting hibernation mode;
- Malware;
- Flaw free disk space;
- Errors in the operation of different programs or drivers.
Rolling back updates
If the update fails, you need to use the options restore previous state provided in this Microsoft product. When starting the device, press F8. The recovery menu will open. 
You need to click on Diagnostics, and then on Restore. Everything will recover on its own. If unsuccessful, use the restore point by clicking on Extra options
. Then a suitable recovery point is selected.
Black screen on boot
The system will come back to life either after a normal reboot or after operations similar to those described in the previous paragraph. The reason for a failed download is usually malware. The most effective way To get rid of it, format it and completely reinstall the system. All important information should be copied. Or check as described below.
Internet connection devices do not work properly and crashes when resuming from hibernation mode
Users operating system we have long noticed that if the download fails, it’s worth trying disconnect from the network and turn off the power Wi-fi routers, network cards, modems or other devices. As a rule, this is due to malfunctions in the operating system. If you exit hibernation mode incorrectly, you just need to press the power button on the case and hold it for 3-4 seconds, and then turn on the PC again.
Checking your computer for viruses
To exclude infection of the device as the reason for the refusal to start, you need to carry out antivirus scan . To do this, download Live cd from antivirus programs and check your computer. It's better that it contains several antiviruses. According to tests by independent laboratories, it is best to use Kaspersky Internet Security, Bitdefender products and scan with several similar programs.
Lack of free disk space
Owners of devices with installed Windows 10 often either save money by installing a low-capacity hard drive, or fill it with downloaded movies, unnecessary games, large files and do not monitor the availability of free space. Therefore, the OS may not start, since it is simply not enough space for work. You can clean it using the software installed on boot disks, or you can simply delete what you don’t need by viewing the contents using a file manager.
Errors when running programs or drivers
To remove the problematic driver you need to log in to safe mode . If it works, then most likely the problem is in the driver of some component or equipment or in the functioning of some program. You can either delete them or edit startup.
There were so many mistakes I heard and saw when installing the Windows OS (and I started doing this back in Windows 98). I want to say right away that most often they are to blame software errors, personally, I would give them 90 percent...
In this article I would like to dwell on several such software cases due to which Windows 7 does not install.
Case No. 1
This incident happened to me myself. In 2010, I decided that enough was enough, it was time to change Windows XP to Windows 7. I myself was an opponent of both Vista and 7 at the beginning, but I still had to switch due to problems with drivers (manufacturers of new equipment simply stopped releasing drivers for more old OS)…
Because At that time I didn’t have a CD-Rom (by the way, I don’t even remember why) the choice of what to install from naturally fell on a flash drive. By the way, my computer was running under Windows control XP.
I actually purchased a disk with Windows 7, made an image from it from a friend, ... Then I decided to proceed with the installation, I rebooted the computer, . And then I run into a problem - the flash drive is not visible, it just happens Windows boot XP from hard drive. As soon as I did not change the Bios settings, reset them, changed download priorities, etc. - all in vain...
Do you know what the problem was? The problem is that the flash drive was written incorrectly. Now I don’t remember which utility I used to burn that flash drive (surely it was all about it), but the UltraISO program helped me correct this misunderstanding (about how to burn a flash drive in it -). After rewriting the flash drive, the installation of Windows 7 went like clockwork...
Case No. 2
I have a friend who is good with computers. Once I asked to come in and suggest at least something why the OS might not install: an error occurred, or rather, the computer simply froze, and each time at a different time. Those. this could happen at the beginning of the installation, or it could take 5-10 minutes. later...
I went in and checked the BIOS first - it seemed to be configured correctly. Then I started checking the flash drive with the system - there were no complaints about it either, even as an experiment we tried installing the system on a neighboring PC - everything worked without problems.
The decision came spontaneously - try inserting the flash drive into another USB connector. In general, I move the flash drive from the front panel of the system unit to the back - and what do you think? The system was installed in 20 minutes.
Next, as an experiment, I inserted a USB flash drive into the USB on the front panel and began copying to it big file- after a couple of minutes an error occurred. The problem was in USB - I don’t know what exactly (maybe something hardware). The main thing is that the system was installed and I was released. 😛
Case No. 3
When installing Windows 7 on my sister's computer, a strange situation occurred: the computer immediately froze. Why? Unclear…
The most interesting thing is that in normal mode(the OS was already installed on it) everything worked fine and no problems were observed. Tried it different distributions OS - didn't help.
It was a problem with the BIOS settings, or more precisely with the Floppy Drive. I agree that most people don’t have it, but in the BIOS there may be a setting and, most interestingly, it’s turned on!
After disabling the Floppy Drive, the freezes stopped and the system installed successfully...
(If you are interested, this article has more details. The only thing is that it is a little old already...)
Other common reasons why Windows 7 does not install:
1) Incorrect recording of a CD/DVD or flash drive. Be sure to double check! ()
2) If you install the system from a flash drive, be sure to use USB ports 2.0 (Installing Windows 7 with USB 3.0 will not work). By the way, in this case, most likely, you will see an error that the required disk drive driver was not found (screenshot below). If you see such an error, simply move the flash drive to a USB 2.0 port (USB 3.0 is marked in blue) and start installing Windows OS again.
4) Before installing the OS, I recommend disconnecting printers, TVs, etc. from the system unit - leaving only the monitor, mouse and keyboard. This is necessary in order to reduce the risk of all kinds of errors and incorrectly specified equipment. For example, if you have an additional monitor or TV connected to HDMI, when installing the OS, you may incorrectly set (sorry for the tautology) the default monitor and the picture on your screen will disappear!
5) If the system still does not install, perhaps you have a hardware problem rather than a software one? It is not possible to consider everything within the framework of one article, I recommend contacting service center or to good friends who understand computers.
All the best…
The topic that I want to discuss in this article is very popular and talking about it in detail so that you understand how and what to do is not so simple. But still, I will try to describe possible ways What to do if Windows 7 does not boot on your laptop or computer. We will also find out why this could happen?! The task ahead of us is not an easy one, namely, to correct the current situation, but there is no need to be afraid. Just follow the clear instructions and everything will be great! Some points may be suitable for other operating systems, but I will focus on Windows 7.
Dear reader, if you really want to solve the problem, then I strongly recommend reading the article in full, and then drawing some conclusions. I cannot talk about all the nuances in one paragraph.
Safe Mode and Last Known Good Configuration
This is a must try! Reboot the computer, press the F8 key continuously.
Attention! In Windows 8, entering Safe Mode is a little different, so it's best to follow the link below to find out all the details. In the list that appears, we are interested in the item called “Last Known Good Configuration (advanced).” Select and press Enter.
About how to enter safe mode on different systems:
What to do if the information above did not help you? We repeat the steps described in the previous paragraph, but select “Safe Mode”.
Next, you can make a choice: fix the problem due to which Windows 7 does not boot manually, or try to do it in semi-automatic mode. Usually I do everything manually, for example, if Windows does not boot after installing the drivers, then I delete the drivers and try to boot. I think you understand that the manual method requires more knowledge on your part, so Windows offers you another option, which I will describe below.
If everything loads, go to the Start menu, Control Panel, System and Security. In the “Support Center” tab, click on the inscription “Restore the computer to a previous state.” See the “Run System Restore” button? Great, then you've come to the right place.
Now click it and follow the instructions.
Next, you will need to select a restore point. In my case, I am asked to select a point on the 23rd, and now the calendar shows the 29th. Therefore, you need to click on “Search for affected programs” to find out what actions you will need to take after recovery.
So, you have familiarized yourself with the affected software when restoring the system and now you can close this window. After closing the window, click "Next".
If you were unable to enter safe mode to restore Windows operation, then there is no need to despair. Below we will look at another method.
Note: at the very beginning, when Windows 7 was just coming out, there was one strange glitch that you might have too. When you turn on the computer, the welcome screen follows and a black screen appears. As I remember, it seemed like there was still an arrow, but nothing else was visible. The cure was very simple - go into safe mode and restart the computer as usual. After that I was able to log into my account without any additional manipulations with Windows.
You may need to reinstall Windows
This option should be considered when you have tried to revive Windows, but all attempts have produced no results.
The very first thing that comes to mind for many, and for me too, is reinstalling Windows 7. But this method, you see, is very long, and if you are a busy person, then access to the computer should be almost constant. Reinstallation is suitable for those who have a lot of free time, or do not have time to understand faster methods, or for those who will not be helped by any of the methods I have listed below for restoring the Windows operating system.
Dwell in detail on Windows installation I won’t, because I wrote about this on my blog:
Here brief instructions: since you do not have access to the desktop, go to the BIOS, look for the Boot or Advanced tab BIOS Features or search on your own. Then in it we find the line “1st Boot Device”, set the value to CD-ROM. What have we done? What we did is that now when the computer boots, it will boot from the disk that is installed in your CDRom, and not from the hard drive. After turning it on, when the inscription “Press any key...” appears on a black background, press any button and get into the Windows installation wizard. Then follow the instructions on the screen.
You can read more about how to boot from disk in my article: “”.
I decided to talk about the installation at the very beginning, because if you were going to reinstall Windows, then perhaps this is some kind of sign to implement it))). But as I said at the very beginning, we will now try to bring your Windows back to life without reinstalling it.
System Restore
First of all, you can use the function that is in the installation disk “System Restore”. I will give an example of the Windows 7 system, but if you have a different system, then this is not a reason to think that you cannot do on your system. The names of the buttons may differ, but the principle remains the same.
So for this procedure we need installation disk with Windows or its image (can be downloaded on the Internet). If you are unable to download the image or do not have a disk, then write to me by email [email protected] or contact your friends who have already installed Windows themselves.
If you don’t have a working disk drive or don’t have one at all, then the article “” will help you create a bootable flash drive.
When you have a Windows distribution, insert it into the drive and restart the computer. If the BIOS is configured for installation, you will see the line:
When it appears, press any key.
If it is not there or Windows boots as usual, then you need to make manipulations in the BIOS. Namely, set loading priorities. Usually in the BIOS settings it is set to HDD, since this is where your Windows is installed.
In order for the computer to start booting from the disk that is in your drive, you need to go into the BIOS and specify CDRom as the first device to boot. I have already talked about this above, if you have not read this point, then it’s time to do so.
So, you pressed any key, now a window will appear where you click “Next”.
In the next window you need to click “System Restore”.
A search will occur. installed systems. If you have one system installed, then there will be one operating system in the list. Select it and click Next.
Often on at this stage A message may appear asking you to restore your system. If this message is displayed on your screen, then click “Fix and restart”. After that, try to log into your account.
If the message does not appear, then in the next window you select your system and click “Next”.
After this, a window will appear where you can select system recovery methods.
– automatic solution Problems.
System Restore - you can use this method, but provided that this function has been enabled.
Restoring a system image – if you have Windows image recovery.
Command line– using certain commands you can revive Windows. This method will be discussed further.
Now click “Startup Repair”. Now you need to wait a little for the utility to try to automatically find the problem and solve it.
System Restore via Command Line
Then enter and press Enter.
A list of commands that can be used in this utility will appear; now you need to enter: Bootrec.exe /FixMbr and press Enter.
Now enter . exe / , then clicking on Enter. Next, exit the utility by typing exit and pressing Enter. Now you can try to log into your account, since the recovery work is complete.
You can also try updating the boot code by entering the command bootsect /NT60 SYS. Then leave as a team Exit.
If the above commands did not help you, then go to command line and enter Bootrec.exe /RebuildBcd. Using this command, you will scan your hard drive to find the systems installed on it.
When the scan is finished, a list of installed operating systems on your hard drive will appear. To add it to the download list, click Y And Enter. After successful completion of the operation, enter Exit and press Enter.
So, we have dealt with the command line. In principle, this should help to get your system to boot.
Inactive hard drive partition
This situation does not occur often, but it is still necessary to talk about it, otherwise the article can be said to be truncated. Let me give you an example, after which you will understand what's what.
Let's say you have several operating systems installed on your computer. Windows systems, which are installed on different hard drives. If the sections hard drives assign incorrect attributes, then you will have problems loading a particular version of Windows.
To check or fix this, you can use the Acronis Disk Director boot disk to change the partition attributes. So, download and burn the Acronis Disk Director boot disk and boot from it. How to do it? Insert the disc into the drive, restart the computer, and it will begin booting from the disc in the drive. But before that, check your download priorities. There should be a CDRom, just like when installing Windows. We have already talked about this in this article above.
When the program loads, pay attention to the checkboxes that are on the hard drive partitions.
In the image above we see that the checkboxes are on the second partitions of the hard drive. You need to make sure that these checkboxes are on the first sections. We got to practice ;). You need to right-click on each first partition of your hard drive and select “Mark as active.”
A message should appear where you click “OK”. This is what it looks like after the whole procedure:
Now all that remains is to click on the “Run” checkbox, wait for the operation to complete and restart the computer. Be sure to remove the disc from the drive.
Hardware problems, BIOS and viruses
HDD. If your system unit, or rather, the hard drive makes suspicious sounds: clicking or tapping, that is, there is a possibility that the hard drive needs to be replaced. To verify this, you need to open the cover of the system unit, turn on the computer and listen to the operation of the hard drive. Also check the wire connection to the hard drive. It is possible that the wires have become disconnected and the computer cannot see the hard drive.
If you suspect that the problem is with the hard drive, then you need to copy all important data to another medium. Otherwise, you may lose them completely.
BIOS. Go to BIOS settings and put the hard drive first so that the download starts from there. Above we looked at an example where we set up a CDROM; you do the same with a hard drive. Just don’t forget to save the changes in the BIOS by pressing the F10 key.
The second method – you won’t believe it, but it actually works! Just go into the BIOS and, without changing anything there, exit, saving the changes that in fact did not exist (by pressing the F10 button). I personally once fixed my friends’ laptop this way, and when they asked me how I did it, my answer was: “Magic and nothing more 😉.” So give it a try, maybe everything will be much easier than you think.
Viruses. Sometimes viruses prevent Windows from booting. If there are viruses on your computer, you need to scan the entire disk for viruses. Here are articles that will be useful to you: “” and “”.
Of course, if you check your hard drive for viruses, you will need to disconnect it and connect it to another computer, since in your case Windows will not load. Or you can use special boot programs, with which you can check your computer for viruses even if you cannot boot your Windows. Here are a couple of them: and.
Attention! There are cases when, after installing updates, Windows 7 stopped loading! Therefore, you may want to try uninstalling recent updates that were installed before the Windows boot problem occurred.
Important! If you see a specific error on your screen, I recommend using a search in Google or Yandex. You can enter into the search not only the error code, but also the words that are used in it. Thus, you will save your time searching for the problem and its solution.
Important! If the system unit makes squeaks when turned on, then you need to use this squeak to determine the problem. Ask how? Here's an article on this topic: "".
That's all I wanted to say. The article turned out to be long, and I sincerely hope that at least one of the methods I described helped you.
Says a lot of unnecessary things, but there is useful information for you:
Many PC users work with Microsoft products. For example, with the corresponding operating systems. They are wearing Windows name(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 clear 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.
- 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.
- 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.
- 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 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 installation new video card The OS does not show the 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 bootloader for Windows 7 and Windows 8. It is initially hidden from users. Delete it when hard formatting disk 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 reading and loading does not occur when starting the PC system registry. 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:
- To restart a computer.
- At the PC boot stage, press "F8" several times.
- Select "Troubleshoot your computer."
- Enter the access password.
- Click on "Startup Repair".
- 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:
- Turn on the computer.
- Click on "F8".
- 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.
appears on the monitor display blue background. 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:
- Get to the motherboard and press the special jumper.
- 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.
- 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 does not boot due to corruption 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:
- Launch the command line in Windows 7. It is advisable to do this in safe mode.
- Write: sfc/scannow /offbootdir=c:\ /offwindir=c:\Windows.
- Click on "Enter".
You can wait for the computer scan and recovery boot files. 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:
- Open a command prompt in safe mode on your computer.
- First enter bcdboot.exe C:\Windows and perform the operation.
- Write bootrec/fixnbr and bootrec/fixboot.
- Execute requests.
- 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.
Hello friends! I have already written many articles about what to do if Windows 7 does not boot. But I haven’t written yet about what you need to do first if your computer refuses to start, or maybe I did :). Well, it’s okay, twice is better than never :).
This will be some advice on how to hit the first one ambulance system in case of failure. I usually write similar tips and describe in them how to restore Windows 7 if a specific error occurs. But today I will write how to try to cure the system from the appearance of various errors and problems when loading. If you turn on the computer, and it frankly does not turn on. Well, you know how it happens, a certain error appears, a blue screen appears, or the computer simply reboots itself, then you need to try to start the computer with the last successful configuration with working parameters.
If we talk about what can cause Windows to stop booting, there are a lot of options. For example, a failure may occur after installing some program or driver. After cleaning your computer from viruses. After incorrect completion of work (when, for example, there was a power outage). I had a problem where I normally turned off my computer in the evening, but in the morning it wouldn’t start, and it seemed like I hadn’t installed anything, but then this happened.
In such cases, the first thing we do is try to start the computer with the last known successful configuration. If this does not help, then you need to look for other ways to solve the problem, for example, searching by error. But as my practice shows, it very often helps to bring the computer back to life. Moreover, all these actions can be done in a few minutes. Now more details.
How to start Windows 7 with Last Known Known Configuration?
Everything is very simple. Reboot the computer and immediately actively press the key F8.
If Windows boots, then everything is fine, lucky. Well, if not, and the problem appears again, then you need to look for other solutions. You can read this blog, I described solutions to many specific errors. Good luck!
