In most cases after replacing the motherboard Windows stops loading. Blue screen (BSOD) appears when loading windows with error STOP 0x0000007B... This is due to the change of the ATA / SATA bus controller.
The fact is that Windows cannot change the controller driver on its own at boot. As a result, when booting, the operating system simply loses its hard drive and cannot continue booting.
The question arises: how to produce replacing the motherboard without reinstalling Windows? After all, reinstalling Windows is not difficult, but all programs and settings will be lost. And this is often unacceptable!
Way replace the motherboard without reinstalling OS three. If you have Windows 7, skip straight to option 3
Option 1 - old working motherboard (Windows XP)
If it is possible to boot into Windows XP with an old motherboard, then you need to replace the IDE and SATA controller drivers with standard ones.
For this in device manager open the properties of the controller (the name depends on the model of the motherboard). In the tab Driver push the button Refresh.
To the question about connecting to the Internet to find a driver, we answer No, not this time and press Further... In the next window, select Install from a specified location and click Further... In the appeared driver search parameters window, select Do not search. I will choose the driver I need and press Further.
In the window that appears, select from the list Standard Dual Channel PCI IDE Controller and press Further.
After completing the driver installation, click Ready and restart your computer.
After loading, we check in Device manager what is installed standard IDE controller driver and turn off the computer.
If there is no driver in the selection list Standard IDE Controller Driver(for example, in the case of a SATA controller), you can simply remove the installed controller driver of the old motherboard. To do this, in the device manager, right-click on the device and select from the context menu Delete... After uninstalling, turn off your computer.
Now produce motherboard replacement to a new one. Windows XP should boot without any problems. After that, all that remains is to install all the drivers on the new motherboard from the disk and that's it!
Option 2 - boot from old motherboard is not possible (Windows XP)
Second option replacing the motherboard without reinstalling Windows XP longer than the first one and should be used if a computer with an old motherboard does not turn on or boot is impossible. We need a Windows XP installation disc. If there is no disk, you can download a disk image (WinXP Professional SP3 with an integrated package of hard disk controller drivers) and burn it to a CD-R disc, for example, using the DeepBurner 1.9 program (the distribution kit can be downloaded for free).
For recovering Windows XP after replacing the motherboard you need to do the following:
Install a new motherboard and connect all devices.
Start booting from the Windows XP installation disc. On the first installation screen (picture below), press ENTER to begin installing Windows XP.
On the next screen, press F8 to accept the license agreement.
The installer will then search for installed operating systems and display a list of them.
Select the operating system to recover and click the button R... The subsequent process is not very different from the usual installation of Windows XP. The difference is that the installer will not ask on which hard disk partition to install the OS and will not prompt you to enter your computer name and username. Be prepared to enter your Windows XP license code and activate it online after installation.
After the installation is complete, you need to install all the drivers on the new motherboard. All programs, user files and operating system settings will remain the same.
Option 3 - fix the IDE controller driver in the registry (Windows 7)
In the case of replacing the motherboard without reinstalling Windows 7, things are a little more complicated. The previous 2 options are not rolled. It will also not work to restore Windows 7 by updating it from the installation disk, since this function can only be launched from an already loaded OS.
But don't be upset! ERD Commander will help us (download the CD image, or make an ERD Commander bootable USB flash drive). With its help, we will make adjustments to the Windows 7 registry required to boot on the new controller.
Let's get started! We boot from a burned disk or flash drive. In the boot menu, select the version of ERD Commander 6.5 for Windows 7.
Selecting the ERD Commander version to download
When asked "Initialize network connection in the background?" we answer Not.
To the question "Reassign drive letters ..." we answer Yes.
Select the keyboard layout and press the button Further... Then we select our operating system from the list and click Further.
Selecting the operating system to which the ERD Commander will be connected
failed, the search for boot problems will start.
Troubleshooting Windows 7 Boot Problems
Push Cancellation so as not to waste time, as this startup repair tool will not help in case of motherboard change. When asked "Do you want to stop troubleshooting?" we answer Yes... The next message that it was not possible to fix the problems, do not get scared and press the button Ready.
In the window that appears, select the item Microsoft Diagnostics and Recovery Toolset.
Now we launch the registry editor.
The first step is to delete the registry branch HKLM \ SYSTEM \ MountedDevices
Now you need to enable the launch of services that load the standard drivers for the IDE and SATA controllers.
Opening a branch HKLM \ SYSTEM \ CurrentControlSet \ services on the left side of Registry Editor. Now check out the following sections in this thread: amdide, amdsata, amdxata, atapi, intelide, msahci, pciide... Parameter Start everyone should have equal 0x00000000 (0)... Start = 0 - the service starts at Windows startup. If it is 0x00000003 (3), double-click on the parameter name (Start) and change the value to 0 (picture below) and click OK.
After start will be set to 0 for all the above registry keys, close the registry editor and restart the computer in normal mode. In most cases, this is enough for Windows 7 to boot successfully. Now you need to install the drivers on the new motherboard.
If it doesn't help
If the actions taken did not help and Windows 7 still does not load and displays a STOP 0x0000007b error, then the required controller driver is not loaded. Let's try to enable loading of all drivers known to the operating system.
To do this, set the parameter value Start equal to 0 in the following 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, ql2300, ql40xx, SiSRaid2, SiSRaid4, vhdmp, vsmraid, aliide, cmdide, nvraid, viaide .
We reboot the computer as usual. The OS should boot up.
The Windows XP boot can also be restored in a similar way, but everything is more complicated there and I will not describe it in this article. Anyone interested can read it.
Users of personal computer operating systems have their own preferences and work habits. Some use standard Windows applications with default settings. For other users, it is extremely important to personalize the operating system interface, use a large number of applications and programs with personal settings.
Reinstalling Windows removes the customized interface. Therefore, users are not eager to "demolish" the old operating system. However, progress is constantly moving forward, "hardware" is quickly becoming 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 a new system while preserving all information and the integrity of Windows settings, then, in the event of a failure or upgrade of the motherboard and hard drive, you cannot avoid installing a new OS.
Prerequisites for saving Windows settings
To protect yourself from possible failure when carrying out the procedure for replacing the motherboard, you must have a copy of the installed system. Today 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, all drivers must be removed. After all, the main problem when replacing a "motherboard" is driver incompatibility, and the ATA / SATA controller is considered the most capricious.
Windows has a special program (sysprep) for cleaning unique data from the system, using which you can painlessly replace the motherboard. Particular attention should 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, write 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 "Actions to clean up the system" menu, select the item "Go to the system welcome window (OOBE)";
- tick the box "Preparing for use";
- in the menu "Shutdown options" indicate "Shutdown";
- press the "OK" button.
The computer will automatically shutdown as soon as the utility performs all the necessary operations. The next step is the process of replacing the motherboard and starting the computer with new hardware.
Recovery of Windows 7 in case of failure of the "motherboard"
However, it is not always possible to prepare for a "painless" motherboard replacement. Sometimes there are sudden hardware failures, and it is no longer possible to boot the working system.
In this situation, a special program ERD-Commander will help, which can be easily downloaded on the Internet, and then burned to a CD. After installing a new motherboard, follow the step-by-step instructions:
- Boot from a pre-recorded disc.
- Select "ERD Commander 6.5 for Windows 7" from the menu.
- In the pop-up window asking about the connection to the network, click "No".
- We answer "Yes" to the program's request for reassigning drive letters.
- We indicate our Windows7, click next.
- We are waiting for automatic fixing of problems.
- In the "System Recovery Options" window, select the lowest item "Run various MSDaRT recovery tools".
- Next, we call the registry editor.
- Find the "MountedDevices" branch and delete it.
- Go to the "HKLM \ SYSTEM \ CurrentControlSet \ services" branch and change the values in the Start parameter to "0".
Board replacement process
On the first boot, Windows will ask for a username. You must create a new account, which you can easily delete later, and you will use your old data. Further, the system itself installs the necessary drivers or prompts the user for those that will not be in the database.
The only drawback of this method is the reactivation of Windows, as the operating system is sometimes tied to previously installed hardware.
This guide is intended for users who would like to replace the motherboard in their computers without reinstalling the system. In particular, the article may be useful to you if:
- you are about to upgrade your motherboard, but you want to keep your current Windows installation along with settings and programs without reinstalling them from the beginning;
- you want to switch the SATA controller mode from IDE to AHCI or RAID (or vice versa) for better disk performance.
If one of the above scenarios applies to you, then you should know that regardless of your goal - replacing the motherboard or switching the SATA controller to another mode - the result will be the same: "blue screen of death" (BSOD) with an error STOP 0x0000007B INACCESSABLE_BOOT_DEVICE when loading the operating system.
The cause of this unfortunate incident is Windows' inability to find the correct drivers for the SATA controller. Fortunately, you can work around the problem to avoid reinstalling Windows. To do this, you just need to "tell" the operating system to use the standard SATA controller driver at startup, and it can help us with this.
To make the appropriate changes to the Windows Registry, simply follow the instructions below.
Before we start, please review the information in the two paragraphs below, as your plan of action depends on one of them:
1. The motherboard has not been replaced yet, so Windows boots normally. In this case, you need to make changes to the registry in a normal Windows operating environment and only then proceed to update the motherboard.
2. The operating system will not boot because you have already installed a different motherboard, or because you changed the SATA mode in the BIOS. In this case, you will have to use the offline registry editor.
Changing the registry before updating the motherboard (Windows boots normally)
These instructions are only for those who start Windows normally, because the motherboard has not yet been replaced. If you already have another board and Windows won't boot, then follow the instructions in the next section of the article.
So, turn on your computer normally, and then open the Windows Registry Editor. To do this, press + R, type regedit, press Enter.
Inside the registry, follow (in the left pane of the window) this path:
HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ services \ msahci
In the right pane of the window, double-click the parameter Start and change its value to 0 (zero). Then click OK.
Now do the same in the following registry key:
HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ services \ pciide
If you are using RAID (otherwise skip this step), then you need to perform the same modification in this section:
HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ services \ iaStorV
That's all. Your machine is now ready to be updated. Turn off your computer, install a new motherboard, and connect all the necessary components to it. Then start the system, enter BIOS and set the ATA mode (IDE-ATA, AHCI or RAID) or leave the default. Windows should start up without problems. When the operating system finishes installing the controller driver, continue installing the drivers for the rest of the devices on the new motherboard.
Windows Won't Boot: Modify the Registry with an Offline Editor
Use this instruction if the operating system does not boot because you have already replaced the motherboard, or changed the SATA controller mode in the BIOS.
In this case, you must use the offline registry editor. To solve this problem, I prefer to use the recovery environment, where you can get, for example, using the disk for installing the operating system.
To open Registry Editor using an installation DVD or USB drive, follow these steps:
Boot your computer using the installation disc. You may need to select DVD / CD or USB as the first boot device in your BIOS setup. For this:
- turn on the computer and press the DEL or F1 or F2 or F10 key to enter the BIOS (the BIOS enter key depends on the computer manufacturer);
- find the Boot Order parameter inside the BIOS menu (this parameter is usually found inside the Advanced BIOS Features menu);
- in Boot Order, select CD / DVDRW or USB (depending on what type of media the Windows installation files are on) as the first boot device. Save changes and restart your computer by pressing F10.
After rebooting, the computer will boot from the installation disc.
After downloading, on the very first screen, click "Next" and then select "System Restore".
If you have Windows 7, in the recovery options window, click Next, and on the next screen, run a command prompt.
If you are using Windows 8.x or Windows 10, then you need to select Diagnostics -> Advanced Options -> Command Prompt.
At the command prompt, enter regedit and press Enter.
In the registry editor, highlight the branch HKEY_LOCAL_MACHINE, and on the File menu, click Load Hive.
Open the disk where the operating system is installed.
Go to Windows \ system32 \ config directory, select file system and click "Open".
Enter a name for the section (for example, Offline) and click OK.
Expanding the HKEY_LOCAL_MACHINE branch, you will see the created section (in our example, it is called Offline).
Expand the new section and navigate to the next subsection:
HKEY_LOCAL_MACHINE \ Offline \ ControlSet001 \ services \ msahci
Open the parameter Start, change its value to 0 (zero), click OK.
Perform the same operation in the subsection:
HKEY_LOCAL_MACHINE \ Offline \ ControlSet001 \ services \ pciide
If you are using RAID (otherwise skip this step), do the same here:
HKEY_LOCAL_MACHINE \ Offline \ ControlSet001 \ services \ iaStorV
Close Registry Editor, Command Prompt and restart your computer. Remove the installation disc so that the operating system can boot normally. Windows should now start without any problems and then install the required hard disk controller drivers.
That's all!
Have a great day!
The result and painlessness of replacing a motherboard with a Windows 7 PC depends on many factors. The version of the operating system is important here (OEM versions, for example, cling to hardware), and the models of motherboards (the more differences, the more chances that Win 7 will start to be capricious), and the platform (if you "move" from AMD to Intel or on the contrary, the likelihood of problems increases). Perhaps many people remember what numbers were broken off by Windows XP when replacing the motherboard ... Seven, I must say, is not a gift in this regard either. Unlike Linux, just changing the motherboard and then tucking in a couple of packages often fails here. To be honest, I only succeeded once in six or seven. This, as you understand, does not in any way pull on a stable result. Therefore, the question of how to replace the motherboard on a Windows 7 PC without reinstalling the OS is still relevant.
Preparatory activities
Before starting such an operation, just in case, I make an image of the partition with the installed operating system. I try to have this image with any major hardware replacement surgery. A couple of times, you know, it helped a lot. And I recommend it to you. This image is made using any program you like. For example, or.
Why does replacing the motherboard often translate into reinstalling Windows? The most common reason is the incompatibility of motherboard chipset drivers. In particular, the incompatibility of the ATA / SATA controller driver with the new controller on the installed "motherboard" can become quite sensitive. In order to avoid such problems, we can simply get rid of the drivers that can cause them.
How do we get rid of the drivers? It's very simple! Using the sysprep utility. Perhaps someone she is familiar with on Windows XP. Personally, I used it to prepare reference images of system partitions with preinstalled software for mass installations on a PC 8 years ago.
This utility is dedicated to removing unique information from the installed Windows operating system. Including, the drivers installed in the system are also cleaned. Now is it clear why I suggested creating an image with an existing system? Sysprep does not touch the software and user settings. This utility must be run front connecting the hard drive with the system partition to the new motherboard.
To launch the utility, press the key combination: "Win + R". In the window that appears, enter the command: “ C: \ windows \ system32 \ sysprep \ sysprep.exe "and click“OK”. After that, a window with utility settings will open (see screenshot). By the way, the screenshot shows the settings that I suggest you make. Select in the drop-down menu "Actions to clean up the system" option "Go to the system welcome window (OOBE)". Next to it there is a place for the "Prepare for use" checkbox. It should also be activated. In the drop-down menu "Shutdown options" you should set the option "Shutdown".
After that, press the "OK" button to start cleaning the system. After the end of this process, the computer will turn off, for which, however, we set the last option.
Replacing the motherboard and starting the system
Only after the final shutdown of the computer do we turn it off from the network (it is better to unplug the power cord). And now you can replace the motherboard or connect a hard drive with an installed and sysprepated operating system to a new system unit.
During the first boot, the OS will install device drivers (it may ask for branded ones, so keep them ready). In addition, she will definitely ask you to set the regional parameters, since they are also removed by the utility.
When the system asks for the username, there is a little trick. Do not include a pre-existing username. Enter something else. Then delete this new user, but the system will not write anything superfluous to the profiles of your users - the settings will not be lost. You can go under them after the first start of the updated system.
As a user, the system will ask you to confirm the date and time, as well as a number of other settings, including the automatic installation of updates. After you enter all these settings (this is much faster than reinstalling the system), the desktop of the user that you created specifically for this process will load. This account can now be deleted and logged in as old users.
The sysprep utility greatly increases the likelihood of replacing your motherboard without reinstalling Windows. In addition, such preparation of the previously installed system takes about half an hour. The only inconvenience is that you will have to reactivate Windows 7, since a number of versions of this OS are tied to hardware. In particular, this applies to the most common in our country legal versions of Windows 7 - OEM (pre-installed on new PCs and laptops). They will have to be activated by phone, since activation via the Internet in this case, alas, is not available due to the fact that the system considers this operation to be reinstallation on another computer, which is prohibited by the terms of the license agreement of this version.
Good day, dear users of computer systems. Today our focus will be on replacing the hardware base of the personal computer. In simple terms, in this article we will walk you through the process of replacing the old printing platform with a new one step by step. This kind of technical work has to be carried out for two reasons - failure of the previous motherboard or updating an outdated desktop assembly database. This is quite a difficult job, so before you get down to business, you should be well prepared. Gather all the information you need on this topic, prepare your desktop and everything you need to successfully complete the assignment. If you know how to install a motherboard into a PC case, then replacing this component will not be difficult for you, because dismantling the old platform is similar to installing it.
Replacing the motherboard this is a rarely done procedure. As a rule, the system bus is changed either in the event of a planned upgrade of components, or in the event of a breakdown of this component. Unlike replacing the system unit, updating the motherboard does not require such a lot of work from the user. Here, high concentration and consistency of actions come to the fore. The owner of a stationary computer is obliged to adhere to the intended plan exactly and not to change the order of the necessary manipulations. Before starting work, make sure that the future base for your computer is compatible with a specific case (micro ATX, mini ATX, ATX). In this case, such a factor as the form factor plays an important role. It is he who determines the standard of compliance between the PC case and the mother base. Therefore, when buying a new printed circuit board, you should clarify its compatibility with the system unit of your computer.
Replacing the motherboard starts with organizing the workspace. Before changing the base of the PC, you should prepare all the necessary tools and equipment for carrying out the planned work. So, let's proceed to dismantling our old motherboard. Carefully disconnect all cables and cords connected to the computer system unit. Next, we remove the charge of statistical electricity from ourselves, according to how it can harm the electronic filling of the machine. We put the case on its side and open its removable cover. If this is your first time doing this, we strongly recommend that you write down the order of operations and tag all major system cables. Now you have to disconnect all wires connected to your old motherboard (board power, CPU power, SATA, IDE, etc.). Remember the main types of connectors on the printed bus to which the power cables, indication and data transmission cables are connected.
Replacing the motherboard a stationary computer requires concentration and attention. The plugs of all disconnected wires must be installed in the corresponding sockets on the new motherboard. The next point will be to disconnect additional devices such as discrete adapters, Wi-Fi modules, TV tuners, etc. We carefully remove them and put them on the table. Particular attention should be paid to one very important component. This is a combined unit with light indication contacts (power supply, HDD operation). On relatively new cases, all these contacts are made in the form of a single plug, which greatly facilitates the work of inexperienced PC users. At the next stage, we take out the RAM strips. After that, you can go to the motherboard itself.
Use a screwdriver to unscrew several screws that secure the device in the metal frame. You need to know that in addition to them, there are insulating racks in the system unit that prevent the motherboard from touching the steel sheets. With a little effort, you can pull out an obsolete motherboard and replace it with a new, more perfect base for your PC. The clips hold the device securely in the case, so be careful when removing the MP. After we got the board out of the box, we need to remove the cooler and the central processor if we want to put them on a new base of the computer. Also, do not forget to remove the rear MP bracket that covers the input / output connectors. Before installing a modern hardware center into a PC case, we recommend users to clean its interior. Free the case from all kinds of dust and only after that you can start installing the new motherboard.
In fact, installing a motherboard into a case is the reverse process of removing it. In other words, we carry out all the above actions in the reverse order. Carefully place the metal back plate in the desired opening, place the board in its niche and connect system cables, power cables, expansion modules, and much more. The main thing here is to clearly adhere to the plan and do everything in order so as not to forget anything. The main thing is not to rush anywhere and to be attentive to the matter. The proverb "measure seven times, cut once" will be relevant here. Better to play it safe, but do everything without mistakes. After you install and connect all the devices, you can start checking the system operation without closing the lid on the stand. Complete with the motherboard, you will have a CD with all the software you need to get started.
