What to do if Windows won't start. Media Player does not work Windows Problem "Disk boot failure" or message with the text "Insert system disk"

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. Entering the market in 2009, the "seven" still does not get rid of the 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 the "seven", this article was written. In it, we will look at how to restore Windows 7 if it does not start.

BOOTMGR is missing

The most common problem that appears during the launch of the "seven".

The reasons for its appearance may be:

• bad sectors of the hard disk or non-working memory cells of the SSD 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;
• activity of viruses (very rarely);
• inept user handling of hard disk partitioning utilities.

There are several ways to make the error disappear. We will consider how to restore a computer using the OS itself.

• If you encounter problems during the startup of Windows 7, press F8 to open a menu with a list of advanced computer startup options.
• Select the "Troubleshooting..." option.

• Select the Russian language and click "Next".
• Select an account with administrator rights.
• We click on "Startup Repair" so that the operating system tries to find and fix the problem on its own.

• If the error is not fixed, launch the command line from the OS Resume Options window.
• We sequentially enter the commands:

"bootrec.exe /FixMbr" - write MBR to the system partition;

"bootrec.exe /FixBoot" - creates a boot entry on the system volume.

• Reboot and start the computer.

If, after following the above steps, the PC still does not detect the installed Windows 7 during startup, run the bootrec.exe command through the command line with the "RebuildBcd" attribute.

It will scan all devices of long-term storage of information installed on the computer for the presence of installed operating systems compatible with the "seven" on them, and will allow you to add them to the boot list.

And in the very last case, when nothing helps to restore the start of the "seven", reserve the old BCD folder responsible for starting the PC and create a new one. This is done using the following chain of commands:

"Disk boot failure" problem or "Insert system disk" message

The startup error is caused by one of several reasons, the essence of which is as follows: the computer is trying to find a boot record on a disk that is not bootable. Factors preventing Windows 7 from starting:

• The device from which the computer starts to boot is not a system drive - try disabling all flash drives, phone, camera, including external hard drives, and reboot the system.
• Check the BIOS settings that are responsible for prioritizing boot devices - there is a high probability that the computer starts to boot from a disk that is not a system disk. 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 considerable bending.

The list of reasons can safely include the absence of Windows 7 installed due to the fact that the disk with it was formatted due to the inattention or inexperience of a novice user, and reinstalling it or restoring a deleted partition will help here.

If none of the options brought the desired result, try to restore the OS, as described in the previous paragraph, and also make sure that the hard drive is working.

Inability to start Windows due to corrupted registry files

Among other things, Windows 7 may fail to boot due to corrupted registry files.

As a result, the computer will inform the user about the problem and launch an application that allows you to restore the operating system to working order.

But the tool for automatic recovery of Windows 7 is far from always effective and, for example, in the absence of a backup copy of damaged data, the user will have to manually restore the operating system.

• We call a window with an extended list of Windows startup 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".

• We confirm the execution of the specified operation by clicking on the "Finish" button and wait while the OS is being restored.

After a few minutes, the Windows 7 recovery will complete, the computer will restart, and most likely it will start normally.

We will fix errors in Windows 10. But we will have to do about the same in Windows XP, 7 and 8. In Windows 7 and later, developers have improved the recovery system after startup problems. In older versions of the system, serious errors often have to be solved by reinstallation.

Disable Peripherals

Try to remember what changes you recently made to the system: whether you installed new devices, devices, or switched something. Perhaps the problem is in one of the hardware components. Try to disable:

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 eliminate all possible sources of the problem.

Internal components such as RAM can also be the cause. In a desktop PC, you can check the performance of the RAM by connecting the brackets one by one.

Check nutrition

If the computer does not turn on at all, pay attention to the power cable and sockets. Don't forget the power switch on the back of the desktop case.

If everything works at this level, but the computer still does not turn on, then most likely the problem is in the power supply, which you are unlikely to be able to fix yourself: you will have to replace or repair it by a specialist.

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

Set up a disk to boot the system

Errors may appear during startup: An operating system wasn't found. Try disconnecting any drives that don't contain an operating system. Press Ctrl+Alt+Del to restart or boot failure. Reboot and Select Proper Boot device or Insert Boot Media in selected Boot device.

The BIOS or UEFI settings may be set to boot from an external device or other logical partition, and not from the system drive. You can restore the default settings like this:

1. To restart a computer.
2. Immediately after the restart, 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 manufacturer of the laptop or motherboard.
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 did not help, you will have to restore the system bootloader. To do this, you will need a bootable USB flash drive or recovery disk with a system that is suitable in terms of bit depth. How to make a bootable USB flash drive or disk, read Lifehacker about installing Windows.

Start the system from a USB 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 that, the system will try to automatically fix the bootloader. In most cases, it solves the problem.

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

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

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

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

To check the drive for errors and corruption, type chkdsk X: /r (where X is the name of the Windows drive). The check usually takes a long time, you have to wait.

Start Windows in Safe Mode

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 through the fault of utilities to speed up Windows, system files may be damaged. In this case, the blue screen of death will appear when the system boots.

Try to start Windows in safe mode without loading drivers and programs in autorun. If the computer works in this mode, you will have to remove the drivers, perform a system rollback and scan for viruses.

If you have restore points, this problem is quite easy to solve. You just need to roll back to the previous stable configuration.

Reinstall system files

The steps above may not help. Then you have to reset Windows settings and reinstall the system while saving the files. Unfortunately, all programs will need to be installed again.

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

The system will roll back to the original settings.

Sometimes users encounter a problem when windows media player does not work, a global search for a solution to the problem begins. There are a lot of tips, but there are only a few really working ones.

Today I will show you 3 easy ways to make the media player work normally, as it was originally. And as a bonus, at the end of the article, you can watch a video tutorial in which a practical example shows how to perform all the necessary actions.

Introduction

If you read on, it means that you no longer run the standard windows media player that you have always used, or maybe you are just a curious user who wants to be armed with knowledge just in case.

Therefore, before proceeding to solve the problem, I will tell you a little about the reasons why people face this problem. After all, the majority starts screaming that they say they caught the virus, yes, of course, this happens, but very rarely. Basically, a failure occurs in the operating system and the media player has data libraries or startup keys in the registry. The situation is not very pleasant, but easily solved.

Dear readers, the main thing is not to rush, do everything in order. You don’t have to immediately jump to the last option, because the problems are different and only by applying all the available steps you can restore the work of your windows media playera. Let's get down to business.

Restart media components

The easiest way to solve the problem with a non-working player is, let's say, rebooting it, for this you need to perform a number of simple steps.

Go to the "Start" menu and select the "Control Panel" section

Now we are looking for the section "Programs and Features / Uninstall or change programs", go:

Go to the "Turn Windows features on or off" section

We are waiting for a few seconds to load and we see a small window in front of us in which we need to find the line “Components for working with multimedia”, our task is to uncheck this line and apply the settings. Be careful, you will be prompted to restart your computer, this must be done.

After you have applied the new settings and restarted your computer, just go back to this menu again and put the checkmark in place that you unchecked, after that we try to start windows media player. If the problem remains, then do not despair, just move on to the next method and everything will work out.

Re-registration of system libraries

The process is quite complicated from the technical side, but in practice it is very easy to perform and thousands of users use their player in normal mode in a minute, I wish you good luck. Our task is to put things in order in the system libraries, for this we simply click the "Start" menu and right in the search bar we write the command: regsvr32 jscript.dll

Then we enter two more commands:

• regsvr32 vbscript.dll
• regsvr32 wmp.dll

It turned out three commands that you applied in turn, the main thing is not to miss more than one, just registered, applied and the same thing with the next and the next. And when finished, we try to turn on our non-working windows media player.

As a result? Problem solved? I think that after that almost all users are happy with the player without problems, but if you are still suffering, because you have some kind of special problem, then it's time to move on to the "heavy artillery".

Automatic Media Player Recovery

At this stage, everything is incredibly simple, our task is to go to the official Microsoft support website and find a free utility there, which should automatically test a number of problem cases related to the windows media player and immediately fix them.

Agree, this is very cool and incredibly simple, the main thing is that it helps. And to do this, we take action.

And now download the same program on your computer:

After you have downloaded the utility, just run it and follow the clear instructions:

For those who still doubt their abilities a little or are worried that they will make a mistake. Then I already foresaw this too and prepared for you a detailed video with practical examples, where I myself do each step in front of your eyes. It remains only to watch and repeat on your computer. Happy viewing.

Watch video: Windows Media Player not working, there is a solution!

After studying all the material, please unsubscribe in the comments, did my recommendations help you solve the problem? Did the player now work or not? Maybe you have applied some of your own method, don’t be greedy, there are already about a thousand of us on this site every day, share your knowledge and many will be grateful to you.

Unfortunately, sometimes you can encounter quite serious problems with turning on computers and starting operating systems, although nothing foreshadowed trouble until a certain point. It happens that but most often the computer turns on, but the operating system does not start. It is these situations that will be discussed below. Consider questions related to why the computer does not boot, and what to do in such situations. There are several universal solutions here.

The computer turns on, but the operating system does not start: reasons

Among all the possible situations when failures occur at the boot stage, there are several typical cases.

There are three options here:

• a black screen appears;
• a blue screen BSoD occurs;
• The operating system starts but cannot fully boot.

In the first case, when the computer does not start (boot does not turn on), messages may appear on the black screen, indicating physical or software problems. In the simplest case, when nothing serious happens, the system may report that, for example, there is no keyboard (for desktop PCs). The simplest solution would be to plug it in and reboot.

If the computer turns on, but the boot does not start, and instead warnings about software failures or missing files appear on a black screen, there can be quite a few reasons for this system behavior. Among them, first of all, one can single out problems with the hard drive, damage to the operating system (accidental or intentional deletion of system components or registry entries), exposure to viruses, incorrect boot sector entries, RAM conflicts, etc. By the way, if a blue screen pops up, this is more related to the “RAM” or recently installed device drivers, which cause conflicts to appear not at the software level, but at the physical level.

What to do if the computer does not boot and the operating system does not start for the above reasons? There are several solutions depending on the situation. To an uninitiated user, they may seem quite complicated, but in certain situations, only them can be used to resuscitate the system. Therefore, you will have to spend both time and effort.

The computer turns on but does not boot: what to do first?

So, let's start with the simplest. Let's assume that the system has experienced a short-term technical failure, for example, due to an incorrect shutdown or power surges.

As a rule, almost all Windows modifications used today usually automatically activate the startup upon restart. If this did not happen, you will have to use the F8 key before starting the system to call an additional boot menu (Windows 10 uses a different method).

The computer turns on, but the operating system does not start? It's not worth getting upset. Here, in the simplest version, you can select the line for loading the last working configuration. If everything is in order with the system components, the system will boot without problems. If this does not help, you will have to use the troubleshooting section, and sometimes even trying to boot in safe mode may be successful.

Possible viral infection

Unfortunately, viruses can also cause such situations. What to do if the computer does not turn on? Ways to solve this particular problem come down to using a powerful one that could check for threats even before the start of the OS itself.

Among the variety of anti-virus software, it is worth noting the disk utilities that start directly from an optical media or USB device, have their own boot records, and even a graphical interface like Windows. One of the most powerful tools is Kaspersky Rescue Disk. Its use can guarantee almost one hundred percent detection of viruses, even hiding in RAM.

RAM conflicts

Now let's see what to do if the computer does not boot, and instead a blue screen appears. As already mentioned, most often this indicates problems with drivers and RAM. We don’t touch the drivers yet, but let’s look at the “RAM”.

The proposed solution to the question of if the computer does not boot is mainly designed for stationary PCs. In this situation, you should remove all the memory sticks, and then insert them one by one and check the load. Perhaps one of them is the link that causes failures. This can be observed when trims from different manufacturers are added.

If the system can somehow boot using the same safe mode, the “RAM” should immediately be checked with the Memtest86 + utility, which will help identify the true cause of the problem.

The system does not see the hard drive

Now the worst situation is when the computer does not boot. Causes and solutions may be related to the hard drive.

A hard drive can have both software and physical problems, although sometimes that's not even the point. The problem can be quite banal: the user in the BIOS settings is set to boot priority from a removable device, for example, from an optical disk that is currently in the drive, but is not a system one. You just need to extract it and re-download it.

On the other hand, another problem that the computer does not start (the system does not start) may be due to the fact that the bootloader and the records of the corresponding sector are damaged. The solution to this situation will be discussed later. But in the simplest case, you can try to recover disk data using Recovery utilities.

Sometimes changing the settings of the primary I / O system BIOS helps. Here you need to find the section related to setting up the hard drive, and deactivate the use of AHCI mode in the SATA configuration parameters.

Finally, a hard drive can also have purely physical damage, and outside interference is indispensable here.

Using the installation disc

Many users clearly underestimate the help that the installation or system image can provide in solving problems associated with situations when the computer turns on but the operating system does not boot.

Firstly, almost any kit includes the so-called recovery console, with which you can fix many software failures, and secondly, you can use the command line here. By the way, this is the most efficient method. Further it will be clear how it works.

Problems with the bootloader BOOTMGR

It is believed that the most common problem when the computer turns on but the operating system does not start is damage to the Windows bootloader (Boot Manager). In this case, the system just writes that there is no system partition (it simply does not see the hard drive).

You can fix this problem if you start from a boot disk and go to the command line in the recovery console, to open it, press the "R" key. Next, you must first use the check disk command, and then fix (repair) the boot records.

The whole sequence looks like this:

• chkdsk c: /f /r;
• Bootrec.exe /FixMbr;
• Bootrec.exe /FixBoot.

After entering commands, punctuation marks are not put, but the enter key is pressed. If for some reason the execution of these commands did not have a positive effect, as an option, you can use the complete rewriting of the boot sector, which is performed by the Bootrec.exe /RebuildBcd command. If the hard drive is not physically damaged, this should work, as they say, one hundred percent.

You can also use some third-party utilities. The most suitable program seems to be a tool called MbrFix, which is included with Hiren's Boot CD. After calling it, for example, for Windows 7, provided that this particular system is installed, and only on one disk (there is no partitioning), the following should be written:

• MbrFix.exe /drive 0 fixmbr /win7.

This will save the user from having to make changes to the boot records, and the boot will be restored.

Problems accessing the NTLDR file

When a message appears that this component is not present in the system, the boot fixation is applied first, as in the previous case.

However, if the result is not achieved, you will need to copy the original file to the root of the system partition. For example, if the drive is "C" and the drive is "E", the command would be:

• E:\i386> copy ntldr C:\ (after copying, the system will boot without problems).

Corrupted or missing HAL.dll file

In the case when the computer turns on, but the operating system does not boot in normal mode, the reason may be a damaged HAL.dll component (the corresponding notification may be displayed on the screen).

In this situation, you need to boot the system in safe mode, call the command console and write the following line in it:

• C:\windows\system32\restore\rstrui.exe (then press the Enter key and restart).

Instead of total

Here is briefly everything related to solving the problem of the impossibility of starting the operating system. Naturally, the issues that the cause could be low power, CMOS battery failure, loose cables, dust inside the system unit, or other malfunctions were not addressed here. But in software terms, the above methods work flawlessly.
