Viruses in the boot sector. Use special download options

Appearance blue ScreenMotable as BSOD, users have almost the real shock. However, in most cases, you can get rid of the problem with several non-hard methods. But you first need to look at a special stop code in the description. Consider the BSOD appearance problem with the STOP code: 0x0000007B (Windows 7) when loading the system. Sometimes the description may also be present inaccessible_boot_device (for systems above the seventh version).

Error 0x0000007B when booting Windows 7: What is the problem?

The nature of this failure can be found out not only in stop code, but also according to the above advanced description of the problem. Even just to translate the phrase into Russian, it will immediately become clear that the link indicates the inaccessible boot device.

Thus, when download windows 7 Blue Screen (0x0000007B) Signals that there were any hard drives with a hard drive, more precisely, with a boot record, to which the system cannot access. However, this is only a general case. As practice shows, the problem may consist, oddly enough it sounds, even in a conventional USB flash drive, which is in port at the time of loading. In addition, the root causes of the failure of 0x0000007B Windows 7 when loading the system can be called still incorrect mounted mode Work controller hard disk, lack or failure of special drivers, damage boot record due to the effects of viruses, etc. Based on the reasons named, in each concrete case We will have to take appropriate measures. Consider the procedure that it is advisable to perform in the sequence in which they will be described.

Failure 0x0000007B Windows 7 when loading: How to fix what to do first?

Perhaps the appearance of a blue screen is a consequence of some short-term failure, such as a sudden power off, when the user has no block uninterrupted power. In this case, you should simply try to restart the computer (maybe even with a preliminary compulsion). At the same time, it is advisable to completely disconnect from system Block All available peripherals and connected drives.

When restarting, an automatic restoration of the system may follow if the failure was really short-term, after which everything will return to the circles.

Use special download options

If the Windows 7 failure is 0x0000007B when loading manages itself again, it should be restarted again, after which before starting the download operating system Press the F8 key several times.

The menu of special start options will appear. First of all, you need to select the launch string of the last workable configuration. In fact, it is the same recovery or system rollback to the previous stable state, when failures and errors were not observed.

Safe mode

In some cases, to eliminate the failure of 0x0000007B Windows 7, you can use the Safe Mode mode (Safe Mode), which can be selected from the menu described for the past case.

If the system is loaded normally, the first thing should be checked for viruses. To do this, it is best to use portable antivirus programs, and if necessary, apply "heavy artillery" in the form of disk utilities With the general name of Rescue Disk, from which the viral scanner will need to be downloaded before the operating system is launched, after setting the appropriate boot priority in the BIOS settings.

Disc Check

In the event of a re-appearance of a problem as a failure of 0x0000007B Windows 7, when loading may require a disc check using for this command line. If the system is loaded at least safe mode, command console is called standard method Using the CMD combination in the "Run" menu.

If it is impossible to download, you will have to use any boot or installation disk (or flash drive), in the menu of which the system is restored, and then call the command line (or from the corresponding partition, or combining SHIFT + F10).

In the console you need to register the team checks Chkdsk. / f / r (sometimes you can use chkdsk / p / r), the execution of which will result in complete check hard Disc with the restoration of damaged sectors. When booting from removable media, you must additionally enter a system partition.

Restore system files and boot sector

In the event that the verification of the results will not give results, you will have to use more complex technique. There are two options: restore system files and recovery (or complete overwriting) bootloader to which there is no access. But, again, for both methods it will be needed to call the command line, as shown above.

In the first case, the SFC / SCANNOW command is prescribed in the console. The process of its execution can be sufficiently long, so you have to wait.

In the second case, several commands are entered. The first is bootrec.exe / fixmbr. Second - bootrec.exe / fixboot. Upon completion of their execution, you need to get out of command Console. And check the system loading. If the result is the same, the console is called again, but it is prescribed a third full overwriter command - bootrec.exe / rebuildbcd. If the failure concerned exactly the boot record, it will give the result in a hundred percent of cases from one hundred.

BIOS settings

But the problem can be from another area. This applies to specialized hard disk controllers, whose settings are located in the BIOS primary I / O system.

When rebooting should be logged in to the BIOS and find something like SATA Mode or SATA Type (lines names, as well as the sections in which they are located in different versions of bios. may differ). In the settings of the controllers themselves, if installed aHCI modeIt must be switched to the IDE, after which save the set parameters (F10 + Y), and then reboot.

Problems with equipment and drivers

It is often possible to occur 0x0000007B Windows 7 when downloading after replacement motherboard or other equipment. In this case, the user deals with the situation when the installed model system board This OS is not supported, which causes the appearance of conflicts, or the system does not recognize it. In this case, the solution will be much more complicated, but if you have installation disk With the drivers it will be necessary to independently install the Material chipset drivers or specify the system when installing the driver, the choice is not from its database, but from removable media.

By the way, there may be hard drives when there are no or incorrectly installed Special AHCI or SCSI drivers. They will also have to integrate into the system.

If quite nothing of the above will help, it may have to be done to reinstall the system with the full formatting of the system partition, and with physical damage to the hard drive - replace it. In extreme cases, if there is no possibility of buying a new hard disk, you can try to use software package HDD Regenerator.But for this it is necessary that the system loads at least in some mode.

Additional options

As an undocumented methods that are used very infrequently, you can use the CMOS settings reset, after 10-15 reversing the power battery on the motherboard. Sometimes it may be necessary to install new firmware BIOS. It is also desirable to check the correctness of the plugs and connectors of the hard drive itself and their integrity. With more serious faults, the computer will have to carry in service center For complete diagnostics.

One of the most common problems with which the Windows operating system is found is a 0x0000007B error.

Consider in more detail when an error occurs and how to deal with it.

Note! It is important not to confuse 0x0000007B error code with a problem of 0xc000007. They are very similar, but appear in different modes of use of the system and have different solutions from each other.

Process for the emergence of malfunction

An error occurs in Windows OS, while most often it appears in the XP version.

In what cases can you meet this problem? Consider two basic cases:

• In the process "Clean" (loading the system on an empty hard drive) installation of the operating system. Remember, the problem may appear when installing Windows of any versions;
• During the transfer of the operating system to any other motherboard. Also, the problem may occur while moving the system to another platform. For example, with Intel on AMD.

In this case, you must restart the computer and check the operating system installer for errors.

Insert it into the drive. Restart the computer and boot from the disk.

To do this, it is necessary to pre-change the order of loading devices in the BIOS.

On the initial installation window, find the key to enable the recovery console. Then enter the command in it. cHKDSK / P / R and press the Enter.

It allows you to restore files damaged on disk.

If the above team did not fit, replace the key P on F. Thus, the team will look: chkdsk / f / r. Press the Enter.

After executing the command, turn off the computer.

Now restart the system, after you have previously changed the download queue in the BIOS according to the standard (the first must be loaded on the OS).

Press the F8 key and in the download options window that opens, select "Safe Mode". Wait for your OS.

After enabling the computer and the OS boot, you must make sure that your device is not infected with viruses that could cause the blue screen appearance.

Use one of the utilities to scan the system. In our case, this is "Dr. Web Current! ".

Remember! After deleting detected viruses, also check all external media that you connect to the computer. They can be a source of infection.

If none of the above methods helped you solve the problems of the appearance of a blue screen, you must complete the full reinstalling of the operating system.

Troubleshooting 0x0000007B error during OS installation

If the error appears during the installation of the operating system, you may have set wrong settings In the computer's bios.

Follow the instructions to correct the situation:

1. Run the process of turning on the computer;
2. Press the ESC key to enable the bios menu;
3. In the window that opens, you need to change the mode of connection of hardware components. To do this, go to the Advanced Settings tab and find the item called "Onchip Sata Type" Select it and define the type instead of ACHI on Native IDE $
4. Exit the bios menu and restart the computer.

Now re-run the installation of the operating system. The error should not appear anymore.

Remember, the external menu of the BIOS window depends on the manufacturer of your device, so the required menu item can be in another tab.

You can learn how to use the BIOS of your device model on the official website of the personal computer or laptop manufacturer.

Stop error: 0x0000007B - solution.

Error 0x0000007B - Causes and Methods Solutions

Error 0x00000000 occurs when launching many applications, but it is typical when used virtual machines (programs like VirtualBox). The message most often appears due to the DEP system component, which is watching to third-party programs Did not use the memory allotted for Windows.

Methods for solving an error 0x00000000

To eliminate the problem, priority, follow the following:

• check the system for malicious software;
• check out system files For integrity, by running the command line under the administrator's rights and execute the SFC / SCANNOW command there.

1. Making exceptions in DEP. We follow the path "My computer" \u003d\u003e "Properties" \u003d\u003e " Extra options Systems "\u003d\u003e" Performance parameters "\u003d\u003e" Prevention of data execution ". We put a tick in the "Enable DEP for All Programs and Services ..." row. Below will be the active button "Add". By pressing it, select the application, starting or the operation of which is called 0x00000000. As a result system component DEP will not be disabled, which is good for stability, and the fulfillment of the previously problematic application will not be limited to this component.
2. Disable DEP. If you have Windows XP, then clamp Win + R, enter and start the C: /Boot.ini query. In the file that opens, we find a value (the Ctrl + F combination will help in this) / NoExecute \u003d Optin and replace it with / noexecute \u003d alwaysOFF. Save the changes in the file and overload the OS. If yours windows version From 7 to 10, then open the command line under the administrator rights. Enter the BCDedIt.exe / Set (Current) command nx alwaysOFF in it, confirming the action by pressing ENTER. This method will definitely eliminate the error 0x00000000, but the consequence can be a decrease in the stability of PC robots.

Windows 10 is one of the most successful "Operations" from the Microsoft Products Line. Success is achieved due to multimillion coded OS values. In this complex structure sometimes failures. Below is a list of error codes and error correction paths in Windows 10.

Problems, their sources and solutions

We will analyze the error codes in Windows 10, find out the causes and give general options that will eliminate system errors:

Brokes Windows 10 Mobile

On versions of Windows WINDOVS for mobile devices Nokia Lumia. And Microsoft can also occur various kinds of problems. Consider several basic codes windows errors Phone 10:

Excellent day!

Error 0x0000000a may occur as during operation installed system Windows 7, and when it is installed for the following reasons:

• the incorrect operation of the driver operating system drivers. Attempting the driver in a secure system area of \u200b\u200bmemory. Very often occurs when connecting and installing driers of cheap Chinese devices type Web cameras, joysticks, uninterruptible power sources;
• failure random access memory;
• bad compatibility of component PCs. Very often lead to this error when windows installation 7;
• incorrect bIOS settings;
• conflict between system applications;
• incompatibility of the system drivers with equipment. Often occurs when trying to automatically use standard Driver Devices for connected to personal computer Devices.

To eliminate the 0x0000000A error, it is important to interpret BSOD correctly. Consider the situation shown in the figure below:

The inscription driver_irql_not_less_or_equal or irql_not_less_or_equal indicates that the error occurred during the BIOS system interrupt, due to accessing the prohibited memory area for this level of interrupt access. That is, at the time of the system interaction with computer hardware.

After the error code 0x0000000a in curly brackets we see detailed information About the error, in this case:

• 0x0075008c will be an incorrect address for this circulation;
• 0x00000002 The level of the necessary interruption of access to work with the above-mentioned memory area;
• 0x00000001 indicates that the error occurred while trying to write to memory, the code 0x00000000 indicated a failure during the read operation;
• 0x83A19829 Address Instructions, which caused an error, at this address can be determined, if the system driver error, or incorrect operation of the application with a hardware PC. To do this, it is necessary to refer to the distribution table of RAM.

Often under construction with an error address (0x0000000a), you can see how the name of the driver was caused by failure, but unfortunately not always.

In this example, the cause of failure - Driver DRV.SYS

To solve the problem, it is worth performing the following steps.

1. If this failure occurred at the time of installation of the driver in Windows 7, it is necessary to restart in a safe power to the PC to pre-turning off the PC and shutting down the installed equipment. To do this, when rebooting, press the F8 key. After the screen appears with the load option, select the "Safe Mode" or "Safe Mode" as shown below and confirm the selection by pressing the ENTER key.
   
2. After download windows systems 7 In safe mode, run the equipment manager by pressing the right mouse button on My Computer. After opening the console, select the installed equipment, click on it with the right mouse button and select the properties, go to the Driver tab, clicks "Delete", install the bird and click "OK".
   
3. After rebooting the system, install the correct driver for this device. We overload the system in normal mode. It happens, an error with 0x0000000A code in Windows 7 occurs after the driver updates or the operating system itself. In this case, overload in safe mode. Start Start Run, in the window that appears, enter the Verifier / Reset command, which will reset the default drivers check parameters, click "OK".
   
4. If a this error It occurs when you switch the Windows 7 system to "Sleeping Mode" or "Hibernation Mode", then you need to install latest updates, Or, on the contrary, make a rollback to the last point of the system recovery.
5. If the error is called after setting up the BIOS, especially games in IRQL interrupts, it is recommended to reset the default settings data, save the BIOS settings.
6. In case of failure as a result incorrect work PC hardware should try in BIOS as follows:
   • disable cache memory, including the second and third level;
   • disable in Bios Plug and Play mode;
   • access to shaded memory;
   • antivirus protection BIOS, if there is such available;
   • it is worth updating bIOS firmware motherboard and video card to the latest version;
   • start the RAM test, it is possible to insert the operational memory in another slot, try to reduce the frequency of operation of the RAM to the most slow plank if you are different;
7. To determine which device in the PC calls the conflict, you can try to turn off the components of the PC in turn. It is worth starting with RAM if you have 2 or more RAM plaques, then we check each of them. Before that, it is important to carry out a complete test of RAM to eliminate failed cells.
8. If the application leads to an error, you can view in the Windows 7 error log. You need to watch in the "Applications" section of the driver errors will be recorded in the "System" section.
