Installed a new motherboard. Motherboard replacement

Question about replacement motherboard without reinstalling windows 7 difficult. Pitfalls will get in the way of ordinary users. Therefore, do not cut from the shoulder. It’s unpleasant to download everything yourself, and then sit in front of the “screen of death” and think about what to do next. It is better to study this issue carefully. It is necessary to understand what steps need to be taken, what problems may arise and what ways to solve them.

Prerequisites

It's important and serious. Perhaps you are not satisfied with one of the components. Technology advances, and your processor is no longer up to the task. Naturally, you need to buy a new chip. But often it is incompatible with specific model motherboard. Then along with it you will have to change the motherboard.

Or maybe you decide to buy new modules random access memory. Your old ones, based on DDR2, have long ceased to cope and are outdated. Even if you only want to expand the amount of RAM, then finding modules of this type will be extremely difficult and impractical. Therefore, it is better to look at DDR4. This is both newer and higher speed memory. But it requires special slots on the motherboard. Why not buy a new motherboard?

The same problems can arise with other components. For new models of video cards, advanced slots are needed - faster and better. The Winchester is being improved and switched to the third revision of Serial ATA a long time ago. To upgrade the system, you need to carefully study the aspects, since replacing the motherboard without reinstalling Windows 7 will be your main problem.

Demolish or save?

And why is it necessary to save the operating system? After all, it is many times easier to just demolish it and put another one after assembling the PC. Of course, for many users this will be the most profitable option. But there are also users who customize the system for themselves to the smallest detail. All personal parameters and necessary applications are important to them.

When you reinstall the OS, everything will naturally be deleted. And if for some this will be the beginning of something new, then for others it can turn into a great tragedy. It is necessary to eliminate all problems and keep personal data.

Tools

In order not to lose the operating system and information, it is better to use a couple of tools. To replace the motherboard without reinstalling Windows 7, two utilities will become useful to us.

Sysprep is a built-in OS tool. It is used to clean hardware parts, reset OS activation, etc. In general, the software will allow you to create an image of an operating system that does not need hardware.

ERD Commander is a tool that will have to be downloaded in advance. It helps even if it is damaged and the download is not possible. This is his main task. There are also additional features. In general, ERD Commander is a useful software for programmers. It helps to restore the system if it was blocked by ransomware viruses, selectively resume files from the registry, etc.

the main problem

Why is it desirable to have a copy at all? The fact is that replacing the motherboard usually leads to a huge amount of driver incompatibility. And if this problem is still fixable with some devices, then the main errors come from the ATA / SATA interface - ports for the hard drive. That's why so often the "screen of death" appears, which brings an endless reboot.

Preparation

Begin the whole process by working with Sysprep. To replace the motherboard without reinstalling Windows 7, you need this particular tool. It cleans up all unique files and drivers. Therefore, you need to do this before the new component takes place on the motherboard.

To start working with the utility, you need to find it through the Win + R command line. A small window will open in which we write the path to Sysprep: "C:\windows\system32\sysprep\sysprep.exe". In a new window, you should configure the software settings.

First, go to the section "Actions to clean up the system" and here you should select the line with the transition to the system welcome window. Here you need to check the box next to "Preparation for use". Now we are looking for a section with "Shutdown Options" and click "Shutdown". Don't forget to end everything with the OK button.

After a few seconds of operation, when the tool has done everything necessary, the system will turn off. Then we proceed to the collection of the motherboard, installation and other similar matters.

Alternative

When replacing the motherboard without reinstalling Windows 7, the registry will also be required. To ensure that the installation does not lead to compatibility errors, whether it is changing the motherboard or changing the controller mode, you need to dig into the system while it is working correctly.

We call the command line Win + R and enter regedit. So you launch the same registry and start working with it. Now you need to go HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\msahci. Open the last folder and look for the Start line on the right. In it, you need to change the value to zero. We return to the column on the left and look for the final pciide folder along the same path. Here again we set the value to zero. For users who use RAID arrays (multiple drives), the whole process is repeated in iaStorV.

Now you can replace the motherboard without reinstalling Windows 7 (64). We turn off the computer, install the updated motherboard in the case and turn on the computer. With the right actions, the process will be correct. The operating system will load the drivers on the controller on its own, and you will have to do all the necessary settings on your own.

Recovery

During all these operations, errors can occur. Incorrect entry of values or erroneous actions cannot be ruled out. This all leads to the fact that it is not possible to start the operating system. We are trying to download and upload ERD Commander to a flash drive. Replacing the motherboard without reinstalling Windows 7 should be easy. As we have already learned, this tool helps to restore the system in difficult situations.

To use this program, you need to download it from the Internet and throw it on a CD or flash drive if there is no drive. Now, when you turn on the PC, the boot drive will see this software and start downloading the necessary information from it. In the window, select the item ERD Commander 6.5 for the seventh OS, or for the version that you had previously installed.

A notification will now appear about "renaming" the drives. We agree with this process. We do not touch the network settings yet, do not forget about the keyboard layout. If several operating systems were installed on the disk, you need to select the previously used one in the next window. If there is only one, then only one line will appear in the table. Click "Next" and see what happens. It usually takes a few seconds for the system to cope with problems, etc.

Now a window with "System Recovery Options" will open. Here you need to select the last item with the restoration of MSDaRT. Next, click on the registry. Now we don't need commands. Replacing the motherboard without reinstalling Windows 7 takes place in the registry window that is already familiar to us.

On the path HKEY_LOCAL_MACHINE\SYSTEM you will find the MountedDevises folder - you need to delete it. The CurrentControlSet folder will be above, you need to find the atapi folder in it, changing the value in the Start line to zero, and repeat this setting in the rest of the archives.

The last step is to work with the Msahci folder. Here again we change the value to zero. The system should boot correctly. If nothing worked out, most likely, the problem is much more complicated. Here, in addition to other software errors, we are talking about conflicts with the built-in video adapter.

Safe mode

Still can't replace the motherboard without reinstalling Windows 7? You can go to " Safe mode". When starting the PC, hold down F8. When the OS loads, go to the "Device Manager" and remove the device that is failing. If you cannot determine it, then it is recommended to simply remove the PCI bus and load all the necessary drivers.

All these operations are designed for people who at least somehow understand the PC. Regular user unambiguously somewhere will get confused, something will choose not that. After that, the system will become a "brick" and programmers will save it. If you are not sure what you are doing, either find friends who understand all this, or ask for help at a service center.

Causes of Windows not working after replacing the motherboard. Often after replacing the motherboard or changing the operating mode of the controller hard drive V BIOS settings(Raid, Compatible, AHCI, Native SATA) the system boot starts as usual, the initial splash screen appears, then a reset, information about the BIOS POST, and again, the boot starts with the same continuation. This usually occurs because the system was unable to load the boot device driver and a critical error occurred STOP: 0x0000007B Inaccessible Boot Device (Inaccessible Boot Device)

In order to get accurate information about the problem instead of rebooting, critical error it is necessary to disable the mode of performing an automatic reboot when it occurs. For Windows XP and older, this can be done through the menu Windows bootloader, if at the very beginning of the download press F8 and select the boot option - Disable automatic reboot in case of system failure

When loading into this mode, upon the occurrence of a critical error, a Windows "blue screen of death" or a BSOD - Blue ScreenOf Death will be displayed on the monitor screen.

A critical Stop 7B error when replacing the motherboard, or changing the operating mode of the hard disk controller, occurs because the new controller is not recognized by the system as, exactly, a hard disk controller.

At the very beginning of the operation of the operating system loader, to perform operations with hard drive special BIOS routines (INT 13H interrupt functions) are used, and that is why the system starts booting and runs normally for a while. However, at a certain point in the boot and initialization of the kernel, since Windows does not use the BIOS interrupt function, it becomes necessary to load the drivers through which the boot device will be accessed (Boot Device). First of all, the system must determine which hard disk controller will be used and load the appropriate driver for it. If the controller is not found, the driver is not found, or its launch is prohibited, the system will complete the boot process due to a critical error in the boot device inaccessibility (stop 7B).

When replacing the motherboard with a different type of board, the hard disk controller, from the point of view of the operating system, will become a different, new device. In progress bootstrap, Plug-n-Play (PnP) devices are identified by the system using special code(PnP-ID), depending on the chipset on which the device or chipset is assembled (chipset), and a new HDD controller assembled on a different chipset will have a different ID. If the system "knows" the new PnP-ID of the HDD controller, and there is a driver to service it, then the motherboard will be replaced without any problems. IN otherwise, which is unknown to the installed system by the ID of the HDD controller, will not allow it to load the driver it needs to work.

And there are 2 possible solutions to the problem:

Make the system work with the new hard disk controller using standard drivers from Microsoft.
- add new driver hard disk controller from the hardware manufacturer to a non-working system.

The first option is much simpler, safer and can be easily done using the usual import of several keys into the registry of a non-working system, for example, using ERD Commander and also ensure its loading and initialization.

One way to resolve stop error 7B is to perform the following steps in sequence:

Translation of the controller, if necessary, in the settings motherboard BIOS boards in compatibility mode (Compatible Mode) with a standard IDE - controller
Usually, this is done in the configuration section of the hard disk controller and can have different settings,
Controller Mode: Compatible
Configure SATA as: IDE
SATA Operation as ATA
AHCI Mode: Disabled
SATA Native Mode: Disable

Using standard drivers from the Windows distribution to boot the system.
Usually, this does not require any special effort, except to check a few registry values.

Windows XP has an unpleasant feature - if you replace the motherboard, then there is a high probability that operating system will stop running. It usually looks like a blue screen on boot with a STOP 0x0000007b error followed by a restart of the computer. Booting in safe mode gives the same result.

But there is a solution to the problem. To do this, you need to boot from the Winternals ERD Commander disk (download link iso image at the bottom of the page) make changes to the registry using the file - mergeide.reg and add the drivers to the Windows\system32\drivers folder. After that, we restart the computer and enjoy the normal boot. It remains only to install the drivers for the new motherboard.

Quick Guide

1. Boot from the Winternals ERD Commander disc with support for your system
2. Write files from the idedrivers folder to C:\WINDOWS\system32\drivers
3. Run mergeide.reg to register standard IDE drivers

When switching from Intel chipset on any other, you must also delete the branch in the registry

otherwise the following error may appear

STOP 0×0000007E

If all this still does not help, you need to reinstall XP in recovery mode. We take for example Zver CD and start the installation not in automatic, but in manual mode and after the license agreement (where the product code is written instead of the agreement), there is a search for installed systems. Select the one you need and press R. (Not to be confused with pressing R to enter the recovery console immediately after loading the disk. There we press Enter) Then everything is as usual only after the installation is completed, we see our long-awaited desktop with all programs. :-)

Is it possible to replace the motherboard without reinstalling Windows? It turns out - yes. But in order to replace the motherboard on a personal PC with a working operating system, while avoiding reinstalling it, you must perform a number of the following steps.

The sequence of operations to restore the system

After a rather lengthy driver removal operation, turn off the PC and proceed to replace the computer motherboard. At the first Windows boot 7 with new mat. board install pre-downloaded drivers for the motherboard.

In the event that it is not possible to prepare systems for an upgrade, or the old motherboard is out of order, after replacement, the system may not boot, giving a BSOD with error code 0x0000007B:

Which indicates a failure of the hard disk controller driver or its incompatibility with the PC hardware.

To fix the problem, perform the following steps:

First of all, in the BIOS, we try to change the operating mode of the hard disk controller from SATA to IDE, and try to boot;
You need to reset the hard disk controller driver, which will force the system to use the standard ATA/IDE driver. To solve the problem, we need boot disk or flash drive and ERD Commander. You can download the ERD image from the link http://blog.fc-service.ru/downloads/erdc.htm, instructions for creating bootable flash drive well written here http://blog.fc-service.ru/soft/erd-commander-usb-download.htm .

After booting from a CD or a bootable flash drive, select Erd Commander for Windows 7.

When asked by the system to change about reassigning drive letters, click "Yes" Skip the network settings, select the keyboard layout. In the operating system selection list, select the one we need a copy of Windows if there are several installed on the disk.

In the window that appears, select the menu item as shown in the figure below.

Choosing an editor Windows Registry 7:

In the registry editor window, find the "MountedDevises" branch and delete:

Now you need to enable the use of standard IDE and SATA drivers. To do this, go to the registry branch HKLM\SYSTEM\CurrentControlSet\Services and edit the Start parameter

setting it to 0

This operation must be done for the services adp94xx, adpahci, adpu320, aic78xx, amdsbs, arc, arcsas, elxstor, HpSAMD, iaStorV, iirsp, LSI_FC, LSI_SAS, LSI_SAS2, LSI_SCSI, megasas, MegaSR, nfrd960, nvraid, nvstor, ql20xx, ql40xx SiSRaid2, SiSRaid4, vhdmp, vsmraid, aliide, cmdide, nvraid, viaide . Next, we find the Msahci parameter by searching the registry branch and set its value to 0.

After the done operations, boot the system in normal mode and install the drivers. If, nevertheless, a BSOD occurs, then its cause is most likely a conflict with the built-in video card or another driver. By the way this algorithm can be applied to a running Windows 7 before the upgrade.

To fix the problem, reboot in bladeless mode. You can enter the mode by pressing the F8 key when the system boots, and select "Safe Mode" from the list. After loading the seven, through the "Device Manager" we remove the equipment that interferes with us from the system. In the case when it was not possible to determine the conflicting device, you can remove the entire PCI bus, by the way, it is best to do this right away, and install all the motherboard drivers instead of the standard ones.

If instead of ERD Commander you have at hand Acronis disk True Image Home 2013 Plus Pack, you can migrate your system by following these steps:

we create an image of the Acronis system on another partition, if there is only one partition, then the image must be created in a protected area previously prepared by Acronis.
we deploy the system to the same partition using Universal Restore, which is able to deploy the system image without being tied to the hardware.

Using this guide, you will certainly be able to replace the motherboard without having to reinstall Windows 7, which in some cases is very convenient and saves you from having to reconfigure the system, applications, etc.

Quite often there is a situation when a user who has upgraded a PC and replaced the motherboard in it, then has to reinstall the system on the hard drive, and, accordingly, reinstall all previously installed programs. This is due to the fact that the PC simply does not want to start and gives a "blue screen" or other error when trying to activate. Let's find out how you can avoid such inconvenience and replace the "motherboard" without reinstalling Windows 7.

The reason that in the described situation a reinstallation of Windows is required is the inability old version OS to find the required drivers for the SATA controller of the new "motherboard". This problem is solved by editing the registry or pre-installing drivers. Then you will not have to reinstall the system software.

Algorithm Windows settings 7 depends on whether you do it before replacing the motherboard or already after the fact, that is, when the reinstallation is completed and an error is displayed when the computer starts. Naturally, the first option is more preferable and a little easier than the second, but even if you have already changed the motherboard and cannot start the OS, then you should not fall into despair. The problem can also be solved without reinstalling Windows, although this will require more effort.

Method 1: Adjusting the OS before replacing the board

Let's immediately consider the procedure for when the system setup is performed before the motherboard has been replaced.

Attention! Before you begin to apply the steps described below, without fail and the system registry.

First of all, you need to see if the drivers of the old motherboard are suitable for replacing it. After all, if they are compatible, then no additional manipulations are necessary, since after installation new board Windows will start in normal mode. So click "Start" and open "Control Panel".

Next, go to the section "System and safety".

Click on an element "Device Manager" in the block "System".

You can also type on the keyboard instead of these actions Win+R and put in the expression:

After that you should press OK.
In the opened "Dispatcher" click on the section name "IDE ATA/ATAPI controllers".

A list of connected controllers will open. If their name contains only the name of the controller type (IDE, ATA or ATAPI) without the name of a specific brand, then this means that the computer has standard drivers Windows and they are suitable for almost any model of motherboards. But if in "Device Manager" the specific name of the brand of the controller was displayed, in this case it is necessary to check it with the name of the controller of the new "motherboard". If they differ, then in order for the OS to start without problems after changing the board, you need to perform a series of manipulations.

First of all, you need to transfer the drivers of the new "motherboard" to the computer. The easiest way to do this is to use that disk with software which comes with motherboard. Just insert it into the drive and download the drivers for the hard drive, but do not install them yet. Even if for some reason the media with the specified software is not at hand, you can download required drivers from the official website of the motherboard manufacturer.
Then you should remove the hard drive controller driver. IN "Dispatcher" double-click on the name of the controller with the left mouse button.

In the controller properties wrapper, navigate to the section "Driver".

Next, click on the button "Delete".

Then, in the dialog box, confirm your actions by clicking OK.

After uninstalling, restart the computer and install the controller driver for the new motherboard using the standard method.
Next in "Dispatcher" click on section name "System Devices".

Find the item in the list that appears. "PCI bus" and double click on it.

In the properties wrapper PCI bus move to section "Driver".

Click on an element "Delete".

As with removing the previous driver, click on the button in the dialog box OK.

After uninstalling the driver, which may take a long time, turn off the computer and perform the motherboard replacement procedure. After turning on the PC for the first time, install the pre-prepared motherboard drivers.

You can configure Windows 7 to change the motherboard and more simple method by editing the registry.

Type on the keyboard Win+R and type the following command in the window that opens:
Then click on the button OK.

In the left area of the displayed interface "Registry Editor" go to the following folders in sequence: "HKEY_LOCAL_MACHINE" And "SYSTEM". Then open "CurrentControlSet" And services.

Next, in the last specified folder, find the directory "msahci" and highlight it.

Move to the right area of the interface "Editor". Click on the name of the element Start.

In field "Meaning" set number «0» without quotes and click OK.

Further in the section services find the folder pciide and after selecting it in the right area of the shell, click on the name of the element Start. In the window that opens, also change the value to «0» and click OK.

If you will use the RAID mode, then in this case you need to perform one more additional step. Move to section "iaStorV" all the same directory services. Here also go to the properties of the element Start and change the value in the field to «0» , don't forget to click after that OK.

After performing these manipulations, turn off the computer and replace the motherboard on it. After replacing, go to the BIOS and activate one of the three ATA modes, or just leave the value at the default settings. Start Windows and install the controller driver and other motherboard drivers.

Method 2: OS setup after board replacement

If you have already reinstalled the "motherboard" and received an error in the form of " blue screen', you don't have to worry. To perform the necessary manipulations, you need to have an installation USB flash drive or a Windows 7 CD on hand.

Start your computer from the installation flash drive or CD. In the start window of the installer, click on the item "System Restore".

Select an item from the displayed list of funds "Command line".

In the opened shell « command line» enter the command:

The interface familiar to us will be displayed "Registry Editor". Check Folder "HKEY_LOCAL_MACHINE".

Then click on the menu "File" and select an option "Load hive".

In the address bar of the window that opens "Explorer" type in the following path:
C:\Windows\system32\config

Then click ENTER or click on the arrow icon to the right of the address.

In the displayed directory, find the file without extension under the name "SYSTEM", mark it and click "Open".

Next, a window will open in which you need to arbitrarily specify any name for the new section. For example, you can name "new". Then click on the button OK.

Now click on the folder name "HKEY_LOCAL_MACHINE" and go to the newly downloaded section.

Then sequentially go to the directories "ControlSet001" And services.

Find a section "msahci" and after selecting it, change the value of the parameter Start on «0» in the same way as it was done when considering Method 1.

Then, in exactly the same way, go to the folder pciide section services and change the parameter value Start on «0» .

If you will use RAID mode, you will need to perform one more step, otherwise just skip it. Go to catalog "iaStorV" section services and change the parameter value in it Start from the current version to «0» . As always, don't forget to press the button after making changes. OK in the parameter properties window.

Then go back to the root of the folder "HKEY_LOCAL_MACHINE" and select the formed section in which editing was performed. In our example, it is called "new", but you can have it with any other name.

Next, click on the menu item called "File" and select the option "Unload Bush".

A dialog box will open where you need to click on the button to confirm the unloading of the current section and all its subsections. "Yes".

Next, close the window. "Registry Editor", shell "Command line" and restart your PC. After the standard start of the computer, install the hard drive controller drivers for the new motherboard. Now the system should activate without a hitch.

In order not to have to reinstall Windows 7 after the motherboard has been replaced, you need to perform the appropriate OS settings. Moreover, this is done both before replacing the "motherboard", and after this procedure. In the second case, manipulations are performed in system registry. And in the first situation, in addition to this option, you can also use the mechanism for pre-reinstalling the drivers of the hard disk controllers.

Operating system users personal computers They have their own preferences and work habits. One uses standard applications Windows with default settings. For other users, it is extremely important to personalize the interface of the operating system, use a large number applications and programs with personal settings.

When you reinstall Windows, the custom interface is removed. Therefore, users are not eager to "demolish" the old operating system. However, progress is constantly moving forward, hardware quickly becomes obsolete and the moment comes to replace some components.

And if the replacement of RAM, graphics adapter, power supply or processor can be done without installing new system maintaining all information and integrity Windows settings, then, in case of failure or updating of the motherboard and hard drive, you cannot avoid installing a new OS.

Preliminary steps for saving Windows settings

To protect yourself from possible failure during the motherboard replacement procedure, you must have a copy installed system. To date, there is a huge variety of software with which you can create a rescue disk with an old operating system.

In order to trick the system when replacing the motherboard, you must remove all drivers. After all, the main problem when replacing the "motherboard" is the incompatibility of drivers, and the ATA / SATA controller is considered the most capricious.

Windows has special program(sysprep) to clean unique data from the system, using which you can painlessly replace the motherboard. Particular attention must be paid to the fact that this program should be run before replacing old components.

So, we can start deleting data using the sysprep utility. To call the program, you must simultaneously press the "Win + R" keys, in the window that appears, enter the address: "C:\windows\system32\sysprep\sysprep.exe" and click the "ok" button.

After the dialog box with the program settings appears on the monitor, you need to do the following manipulations:

in the menu "Actions to clean up the system" select the item "Go to the system welcome window (OOBE)";
check the box "Preparing for use";
in the "Shutdown Options" menu, select "Shutdown";
press the “OK” button.

The computer will automatically turn off as soon as the utility performs all the necessary operations. The next step is the process of replacing the motherboard and running the computer with the new hardware.

Restoring Windows 7 when the motherboard fails

However, it is not always possible to prepare for a "painless" replacement of the motherboard. Sometimes there are sudden failures in the equipment, and it is no longer possible to boot the working system.

In this situation, the special ERD-Commander program will help, which can be easily downloaded from the Internet and then burned to a CD. After installing a new motherboard, follow step by step instructions:

Boot from a pre-recorded disc.
In the menu, select "ERD Commander 6.5 for Windows 7".
In the pop-up window with a question about connecting to the network, click "No".
We answer “Yes” to the program’s request to reassign drive letters.
We indicate our Windows7, click next.
Looking forward to the automatic fix.
In the "System Recovery Options" window, select the lowest item "Run various MSDaRT recovery tools".
Next, we call the registry editor.
We find the branch "MountedDevices" and delete it.
Go to the "HKLM\SYSTEM\CurrentControlSet\services" branch and edit the values in the Start parameter to "0".

Board replacement process

On first boot, Windows will ask for a username. You must get a new account, which you can then easily delete, and you will use your old data. Further, the system itself installs the necessary drivers or asks the user for those that are not in the database.

The only downside this method is repeated Windows activation, since the operating system is sometimes tied to previously installed hardware.
