Windows 7 computer does not start. Windows OS does not load

If a user has a problem when Windows 7 does not start on a computer or laptop, then this article will help solve this difficult problem. Starting Windows 7 is sometimes impossible due to errors occurring in the system after hardware problems, incorrectly installed software, malicious utilities, etc.

But the most common reason why Windows 7 sometimes won’t load lies in the operating system itself.

Solving the problem

In the case when all the initial stages Windows launch 7 on a PC or laptop runs fine, but Windows 7 still doesn’t start completely, which usually confuses novice users. Although if available detailed instructions, the question: “What to do?” will not appear even for beginners. If the cause of the problem is a hardware failure, then it will be indicated by a signal from the laptop speaker or desktop computer during POST test. If this is the case, then the OS will not start.

But if the problem is of a software nature and the process stops at the stage Windows downloads 7, this means that the user is faced with the most common problem that can be solved using an algorithm of typical actions.

Instructions for action

You must use an OS recovery tool. During the PC startup process, if Windows 7 does not start, the system often recommends that the owner of the computer or laptop select boot options. If for some reason such an offer has not been received, then the user can independently open this menu by clicking on the “F8” button. Then proceed to "Sevens".

What to do if the above instructions did not solve the problem?

To fix the problem when Windows 7 does not start, you need to use a CD with the OS:

1. Insert the installation disk into the PC drive;
2. Start the system from the disk (in the BIOS the appropriate order for booting the system from media must be set);
3. In the window that appears, click on “Apply recovery functions that resolve OS boot problems” and click on “Next”;
4. Then in the “OS Recovery Options” menu, click on “Startup Repair”;
5. Wait until the system analysis is completed and the causes of failures are eliminated;
6. Reboot the PC;
7. In BIOS, set the system to start with hard drive (When exiting the BIOS, be sure to save the adjustments made);
8. Restart the computer again;
9. Ready! Windows 7 will now boot normally.

Using the command line

If for some reason it was not possible to restore Windows using the installation disk, then there is another way to do this through the command line.

First, you need to take the steps indicated in the paragraph about restoring normal loading of the “Seven”. The only changes are that simply in the “ ” menu you now need to specify the section “Command Line”.

What to do when you fail to achieve a positive result by following the above instructions?

If success was not achieved and the user has already reached this part of the article, then the problem cannot be classified as a typical failure of a bootable OS distribution. You will need to do all further actions safely Windows mode. It is recommended to analyze drive “C” for the appearance of broken clusters.

To login " safe mode» you must do the following:

Why are preventive measures important?

Windows 7 has a special system that can make special reference points, with the help of which, if necessary, it is restored. By using this protection function, even a novice user can always easily return the OS to a working state.

For example, in case of failures due to incorrect installation of applications, drivers and other utilities such as codecs, or when errors occur due to adjustments being made to the registry.

It should be noted that in “Seven” it is possible to allocate a fixed amount of memory on the hard drive specifically for such protection of the operating system. Implementation available in Windows 7 self-configuration protect files along with system data, or you can do this separately.

We will fix errors in Windows 10. But approximately the same will need to be done in Windows XP, 7 and 8. In Windows 7 and later releases, the developers have improved the recovery system for startup problems. In older versions of the system, serious errors often have to be resolved by reinstallation.

Disable peripherals

positive.org

Try to remember what changes you recently made to the system: did you install new devices or switch something. There may be a problem with one of the hardware components. Try disabling:

1. USB drives.
2. Card readers.
3. Printers.
4. Scanners.
5. Cameras.
6. All other external devices.

If this does not help, disconnect the keyboard and mouse: you need to exclude all possible sources of malfunction.

It may also be due to internal components, such as RAM. On a desktop PC, you can check the performance of the RAM by connecting the strips one by one.

Check power

takprosto.cc

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 your desktop computer.

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 it or have it repaired by a specialist.

It is possible that the computer turns on, but only for a short time. This is the same problem with the power supply.

Configure the 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 may be set to boot from external device or another logical partition, and not from the system disk. You can restore default settings like this:

1. Restart your computer.
2. Immediately after restarting, press the 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 or motherboard manufacturer.
3. In the settings, set the desired disk to the first place in the boot.
4. Select the Save and Exit option to save your changes.

If the above does 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 of suitable capacity. How to do bootable USB flash drive or disk, read Lifehacker about Windows installation.

Start the system from a flash drive or disk by selecting the desired option in the boot menu. In the Windows installation menu that opens, select “System Restore.”

From the recovery menu, select Troubleshooting → Advanced options → Startup Repair. After this, the system will try to automatically fix the bootloader. In most cases this solves the problem.

The same can be done manually via the command line, but it is better to select the automatic option so as not to aggravate the situation.

If this method does not help, the problem probably lies in the hardware: the hard drive is damaged.

From the recovery menu, select Troubleshooting → Advanced Options → Command Prompt.

At the command line, you need to enter the commands one after another: diskpart → list volume (be sure to remember the name of the Windows disk) → exit.

To check the disk for errors and damage, enter the command chkdsk X: /r (where X is the name of the Windows disk). The check usually takes quite a long time, you will have to wait.

Start Windows in Safe Mode

Due to a sudden shutdown of the computer during the installation of operating system updates, cleaning of viruses and unnecessary entries in the registry, or due to the fault of utilities to speed up Windows, Windows may become damaged system files. In this case, when the system boots, “ blue screen death."

Try starting Windows in safe mode without loading drivers and programs in startup. If the computer is running 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'll have to reset Windows settings and reinstall the system while saving the files. Unfortunately, all programs will need to be reinstalled.

In the recovery environment, select Troubleshoot → Reset this PC → Keep my files → Reset.

The system will roll back to the original settings.

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

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

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

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

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

Possible reasons and what to do:

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

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

• If you have several installed on your hard drive at once operating systems, then perhaps there was a conflict between them.

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

Windows XP won't boot due to registry problems

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

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

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

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

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

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

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

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

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

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

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

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

Why Windows won't boot and freezes during boot

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

Here are the main reasons why this can happen:

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

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

• Computer hard drive failure.

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

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

Blue screen of death appears

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

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

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

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

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

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

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

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

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, then do not 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.

I will not dwell in detail on installing Windows, since 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 BIOS Features tab, or search for it yourself. 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 the hard drive is set in the BIOS settings, since that 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 at this stage a message may appear in which you will be asked to restore the 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 on the condition that this function was turned on.

Restoring a system image – if you have Windows image for 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 completed.

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 the 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, with command line We've sorted it out for you. 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 a boot disk Acronis Disk Director to change partition attributes. So, download and burn bootable Acronis disk Disk Director and boot from it. How to do this? 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

Hard drive. 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 can try uninstalling recent updates that were installed before the problem appeared Windows boot.

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:
