• Recovering mbr windows 7 without boot disk

    For many years, Microsoft has been improving the recovery system for the Windows operating system, both in Windows 7 and Windows Vista she works practically automatic mode. If you boot from installation disk Windows 7 and click " System Restore" ("Repair Computer"), system Windows recovery will be launched and will independently try to correct all errors that it finds. She can fix large number problems, however, it is quite likely that the bootloader is damaged, and the recovery system cannot cope with this problem. In this case, you can restore the bootloader manually using the Bootrec.exe utility.

    The Bootrec.exe application is used to fix errors associated with bootloader corruption and, as a result, the inability to start the Windows 7 and Windows Vista operating systems.

    Sequence of actions

    Description of keys for launching the Bootrec.exe utility

    Bootrec.exe /FixMbr

    Launched with the /FixMbr key, the utility records the main one, compatible with Windows 7 and Windows Vista boot entry(Master Boot Record, MBR) in system partition. Use this option to resolve problems with the master boot record being corrupted, or if you wish to remove non-standard code from it. In this case, the existing partition table is not overwritten.

    Bootrec.exe /FixBoot

    Launched with the /FixBoot key, the utility writes a new boot sector compatible with Windows 7 and Windows Vista to the system partition. This option should be used in the following cases:

    1. The Windows Vista or Windows 7 boot sector has been replaced with a non-standard boot sector.
    2. The boot sector is damaged.
    3. Has been installed previous version Windows operating system after installing Windows Vista or Windows 7. For example, if Windows XP was installed, NTLDR (Windows NT Loader, Windows boot loader NT), the code of the standard NT 6 boot loader (Bootmgr) will be overwritten by the Windows XP installation program.

    It should be noted that a similar effect can be achieved using the bootsect.exe utility, also located on bootable media Windows 7. To do this, you need to run bootsect.exe with the following parameters:

    Bootsect /NT60 SYS

    The boot sector of the system partition will be overwritten with BOOTMGR compatible code. You can learn more about using the bootsect.exe utility by running it with the parameter /help.

    Bootrec.exe /ScanOs

    Launched with the /ScanOs key, the utility scans all disks for installed Windows Vista and Windows 7 operating systems. In addition, when using it, a list of found systems is displayed that are at the moment are not registered in the Windows boot configuration data store (Boot Configuration Data (BCD) Store).

    Bootrec.exe /RebuildBcd

    Launched with this key, the utility scans all disks for the presence of installed Windows Vista or Windows 7 operating systems. Found operating systems are displayed in a list from which they can be added to the Windows boot configuration data store (Boot Configuration Data Store). Also use this option if you want to completely rebuild the boot configuration data store. Before doing this, you must delete the previous storage. The set of commands could be as follows:

    Bcdedit /export C:\BCDcfg.bak attrib -s -h -r c:\boot\bcd del c:\boot\bcd bootrec /RebuildBcd

    The example above exports the current boot configuration store to C:\BCDcfg.bak, removes its system, hidden, and read-only attributes, removes it with DEL, and rebuilds it with bootrec /RebuildBcd.


    Enlarge picture

    Of course the utility Bootrec.exe is very functional, however, it will not help if, for example, the Windows boot loader file bootmgr damaged or physically missing. In this case, you can use another utility, also included in the Windows 7 distribution media - bcdboot.exe.

    Recovering the boot environment using BCDboot.exe

    BCDboot.exe is a tool that is used to create or restore a boot environment located on the active system partition. The utility can also be used to transfer download files.

    Command line V in this case might look like this:

    Bcdboot.exe e:\windows

    Replace e:\windows with the path that matches your system.
    This operation will repair a corrupted Windows boot environment, including boot configuration data (BCD) store files, including the bootmgr file mentioned above.

    Syntax of bcdboot command line parameters

    The bcdboot.exe utility uses the following command line parameters:

    BCDBOOT source ]

    source

    Indicates location Windows directory, used as a source when copying boot environment files.

    Optional parameter. Sets the boot environment language. The default is English (US).

    Optional parameter. Specifies the drive letter of the system partition where the boot environment files will be installed. By default, the system partition specified by the BIOS firmware is used.

    Optional parameter. Enables detailed logging mode of the utility operation.

    Optional parameter. Combines the parameters of the newly created and existing boot storage record and writes them to the new boot record. If an operating system boot loader GUID is specified, combines the boot loader object with the system template to create a boot entry.

    Restoring the Windows 7 bootloader without a distribution and creating a dual boot using the MultiBoot program

    Annotation

    Restoring the Windows 7 boot loader after installing Windows XP and creating a boot menu are described in detail in the article Installing Windows XP on a computer with Windows 7 and is not difficult if you have a Windows 7 installation disk or a Windows 7 recovery disk. However, there are situations when neither one nor the other is at hand. The program is intended to help in this case MultiBoot, developed by participants of the OsZone conference.

    Download MultiBoot program possible at OSZone soft portal from this page.

    Program page on OsZone-Wiki: MultiBoot.

    Development history

    The program is based on Pavel Kravchenko’s idea to automate and present in a graphical interface (GUI) the user’s work on the command line - utility FixBootFull. However, the advent of the Windows 7 operating system prompted the improvement of the utility and the expansion of its functionality. Currently, the program covers almost all the necessary functions of the utility bcdedit.exe, designed to work with operating system records, with the exception of the function of deleting an entry from the boot store (BCD) and adding an entry for a second Windows 7 or Vista system to the BCD.

    Program features

    With this program you will be able to:

    • recover Windows Vista or Windows 7 boot files lost when formatting the active partition; New
    • restore the Windows Vista or Windows 7 bootloader that was erased during the installation of Windows XP;
    • create a dual-boot configuration both after and before installing Windows XP;
    • specify the default operating system;
    • edit entries of any operating system in the boot manager and determine their position in the boot menu;
    • set a timeout for the menu with the choice of loading operating systems;
    • export and import boot configuration data;
    • display detailed information about the download store, about boot files, layout by disks and partitions, and also save them to a text file;
    • launch the command line to execute commands manually;
    • specify file parameters boot.ini rdisk And partition for boot errors in Windows XP. New

    To make it easier to work with the program, each control element is equipped with a tooltip.

    Starting the program

    Download the archive with the program and unpack it into a separate folder. If you booted into Windows XP, just run the program, and if you booted into Windows 7/Vista, run it as an administrator. After starting the program:

    • will collect information about boot configuration data (BCD), disks and partitions, and installed Windows operating systems;
    • will analyze the bootloader file version bootmgr;
    • will search Windows XP boot files, including the contents of the files boot.ini(if there are several of them).

    The result of the analysis will be reflected in the field Configuration Details on the tab Additionally.

    The proposed version includes utilities bootsect.exe, so you do not need to additionally download or copy it from the Windows 7 installation disk, as well as the utility bcdboot.exe, available in the Windows\System32 folder of the Windows 7 operating system. You can read about the capabilities and use of the utility in the article BCDboot command line options.

    Recovery tab

    Let's look at the program functions implemented using this tab.

    Each control element is equipped with a tooltip, which makes working with the program easier.

    Figure 1 – “Recovery” tab: restoring the Windows 7 boot loader and adding an entry about Windows XP to the boot menu.

    Restoring the Windows Vista or Windows 7 bootloader that was erased during the installation of Windows XP

    When the checkbox is active Restore bootloaderWindows Vista /7 on all drives The command to repair the MBR compatible with Windows 7/Vista will be executed:

    Bootsect /nt60 All

    In the event that the computer has more than one hard drive, the command will be executed with the key /force.

    If you are using the program as a BCD entry editor, uncheck this box.

    Adding a Windows XP boot entry to the boot menu and storage.

    You can add an entry to boot Windows XP both before and after installing it. If there is no Windows XP boot entry in the BCD, you will see a second checkbox: Add an entry to the boot menu for Windows XP, and in the field Executed commands and report– list of required commands.

    Note: before adding the Windows XP download entry to the download store, in the combo box Select operating system there is no line about it, but the settings will be applied specifically to the record being created. On at this stage Can:

    • rename the created entry (by default – “Windows XP”);
    • set Windows XP as the default operating system (if you do not want this, uncheck the corresponding box);
    • determine the location of the entry in the boot menu (by default the entry will be located at the top of the list).

    After clicking the “Run” button, the scheduled commands will be executed.

    You can prepare in advance to install Windows XP and create a boot menu. To do this, run the program in Windows 7, configure the boot menu options in the same way as described above, but since there is no need to restore the bootloader at this stage, uncheck Restore bootloaderWindows Vista/7 on all drives and press the button Execute. After installing Windows XP, you only need to restore the Windows 7 boot loader.

    Edit any operating system entry in the boot manager.

    The Multiboot program allows you to edit existing boot records of operating systems. To do this, just uncheck both checkboxes on the tab Recovery over the field Editing a post. To start editing, select the desired entry in the combo box Select operating system. The remaining functions are similar to those applied to the created Windows XP boot record and are not difficult:

    • renaming the selected entry;
    • setting the selected system as the default boot system (if you do not want this, uncheck the corresponding box);
    • changing the location of the entry in the boot menu (at the top or bottom of the list).

    Setting a timeout

    To do this, you need to change the value in the checkbox field Set OS selection timeout.

    The command will be displayed in the control field

    X:\Windows\System32\bcdedit /timeout nn

    where X is the letter of the partition on which Windows 7 is located, nn is the number of seconds.

    Executed commands and report field

    A list of commands that you would need to run on the command line is displayed in the box Executed commands and report. After analyzing the existing BCD parameters, the program adds to the list only those commands that change the current ones. For example, if the timeout parameter is 15 seconds, it will not appear in the list of commands. Progress and results are visible in the field Executed commands and report. The text can be copied to the clipboard and then pasted into a notepad file or forum post.

    When you press the button Execute The boot menu will begin to be created or modified, and the Windows 7 boot loader will be restored.

    Restoring boot of Windows 7 or Windows Vista after formatting the active partition

    Sometimes during the installation of Windows XP, more often during reinstallation, unsuspecting users format the active partition on which the Windows 7 boot files were located. Naturally, after installing Windows XP, the ability to boot into Windows 7 disappears. If you have an installation disk with Windows 7, restoring startup is a matter of a couple of minutes, but what if you don’t have one? MultiBoot is equipped with tools to solve this problem without a distribution kit. At the beginning of the article I mentioned that the utility is used for this bcdboot.exe.

    Figure 2 – “Recovery” tab: recovery of Windows 7 or Windows Vista boot files after formatting the active partition.

    A window to restore the ability to boot Windows 7 will appear when the program does not detect on the active partition (or partitions, if there are 2 or more hard drives) hidden BOOT folder. All you have to do is configure the utility keys and select the active partition for BCD recovery. This program function is especially valuable for those who have Windows Vista installed, since the utilities bcdboot.exe not in Windows Vista.

    WITH MultiBoot BCD recovery– just a matter of a couple of mouse clicks.

    “Advanced” tab

    This tab provides you with the opportunity to see boot configuration data and the layout of disks and partitions in the field "Configuration Information".

    Figure 3 – “Advanced” tab

    If you need a text file containing the boot configuration data, click the Copy or Save links. In the first case, the information is saved in the clipboard, and you can use it as you wish. In the second case, you will be prompted to create text file. There are two options for saving information:

    The first will contain information about the operating system entries that form the boot menu, which is similar to running the command:

    Bcdedit /enum active

    The second option will contain information about all the entries contained in the BCD, which is the same as running the command:

    Bcdedit /enum all

    Data about Windows boot files, disk and partition layout, installed systems Windows, the text of the boot.ini files will be added in any case.

    Tools area

    Creation backup copy BCD is necessary so that in the event of an unsuccessful installation of the operating system or after experimenting with the boot menu, it is possible to return the boot to a working state. To perform BCD export, click on the link Save. You will be asked to select a location to store the backup in the program folder. You can change it if you wish.

    If you have a backup of your download data previously created by the program, you can restore it using the link Restore. To do this, click on it, specify the location where the backup file is stored, then click Open.

    Console subsystem of the program

    Help about the commands used in the MultiBoot console subsystem can be obtained by running

    MultiBoot/?

    Figure 4 – Operation of the console subsystem of the program

    To work with utilities bcdedit And bootsect you can use Multiboot, for example, to get information about BCD entries on partition C: with output to a text file:

    MultiBoot -bcdedit /store c:\boot\bcd >c:\bcd_on_c.txt

    or rewrite the bootloader on multiple hard drives:

    MultiBoot -bootsect /nt60 all /force

    Separately, I would like to dwell on the team

    MultiBoot –buildbootini

    This command can be used to check if the file settings are correct boot.ini, especially if booting Windows XP in a dual boot configuration is not possible. As a result of executing the command, the text of the file will appear in the command line window boot.ini Restoring Windows 7 boot after installing XP and creating a dual boot on the forum.

    Using a laptop or desktop PC on operating system Windows 7, users often encounter problems with its loading, system freezing or blue screen. The main causes of these problems may be viruses, deletion of system files and low-quality software. To solve these problems, it is enough to use system restore points.

    These restore points are designed to restore the OS to the point in time when it was worked stably. Each restore point is created automatically when there are some changes in the system. For example, when installing a driver or software.

    In this material we will pay special attention command line, with which we will restore Windows 7. By restoring the OS through the console, you will significantly speed up the process. Our article will be especially interesting for beginners system administrators and advanced PC users.

    Running System Restore in the console when the OS boots normally

    If in Windows 7 after booting there is unstable work, programs do not open, system components freeze and do not work, then in this case it is necessary roll back to the previous saved point. Let's launch the console as Administrator. To do this, go to the menu “ Start" and in the search we will type " CMD" Then right-click on the result found and select in context menu paragraph " Run as administrator».

    After these steps, the console will start in Administrator mode. In the running console window, enter the command rstrui.exe

    After executing the command, the System Restore Wizard will open. Click the Next > button in the window that appears to proceed to selecting recovery points.

    Let's choose suitable the restore point at which Windows 7 functioned normally and we will continue.

    In the window that opens, click the Finish button and confirm the message. After confirming the message, we will start a system rollback to the selected restore point. If the restoration is successful, you will see a corresponding message.

    As you can see, launching recovery through the console is not difficult at all.

    Recovering via the console in safe mode

    The recovery method described below is necessary if Windows 7 cannot start in the usual way. To go to the alternative Windows boot menu, press the F8 key when the system starts (there may be other options, for example, Del or others). In this menu you need to select the item shown in the image below.

    By selecting this item, the operating system will boot without GUI , and the only means through which the system can be controlled will be console. In the console window, enter the already familiar command rstrui.exe

    By executing this command we will open the System Restore Wizard. Let's select a suitable access point in the wizard.

    From the example it is clear that it is identical to the previous one. The only difference is the launch Windows in safe mode with console support. Typically, this method almost always works, even if the system heavily damaged by viruses, since at startup the OS loads only the main drivers and there is no access to the Internet.

    Running System Restore in the console using the Windows 7 installation disc

    If the second method does not help restore the system, then the only option to start recovery using the console is installation disk or boot flash drive. Let's turn on our PC and boot from the Windows 7 installation disk.

    Now let's move directly to the console itself. To do this, click the hyperlink “ System Restore", which will start searching for installed systems.

    Let's select the operating system we need and move on to the next window.

    In this window, select the item “ Command line", after which it must start.

    In the console, we will type the command rstrui.exe that is already familiar to us. After executing this command, the recovery wizard will start. The work of the master is identical to the examples described above. Therefore, we will skip further description of the recovery wizard.

    Recovering the Windows boot record using the console

    Using a PC with operating system Windows system 7, users often encounter problems loading it and receive messages of this type when the OS starts.

    Or something like that.

    The main culprit for this problem is a corrupted boot record. MBR or broken boot configuration BCD. You can solve this problem using the utility Bootrec.exe. Using the commands " /FixMbr" And " /FixBoot"The utility can create a new boot entry and fix it.

    To use these commands, we need to boot from the installation disk and launch the command prompt, as in the previous example. Let's use the first command " /FixMbr» utilities Bootrec.exe.

    By running this command we have fixed our boot entry MBR. If this command does not help, then use the second command " /FixBoot» utilities Bootrec.exe.

    By running this command we will create a new boot entry that will allow Windows 7 to start.

    From the example it is clear that using Bootrec.exe in most cases, you will be able to restore or fix the boot record in Windows 7. I would also like to note that the main reasons that damage or overwrite the boot record are:

    • Resizing local disk with the operating system using special software;
    • Installing old Windows OS on top of new ones. For example, Windows installation XP on the same PC with seven installed;
    • Third party recording boot sector, which does not support Windows. For example, linux bootloader GRUB;
    • Various viruses and malware.

    By paying attention to the reasons that damage or overwrite the boot record, you can keep your PC in working order.

    BCDboot utility

    The Windows 7 installation disc contains another great utility that can be used to restore the OS. Let's also boot from the installation disk into the command line. Then enter the command shown below.

    In our Windows case installed on drive “E:\”, so we specified the path in the command “ E:\windows" By running this command we will restore the configuration files BCD, as well as the bootloader file bootmgr.

    By entering the bcdboot.exe command in the console, you can see a description of the utility, as well as a list of additional keys that can be used when starting it.

    Console utility MBRFix

    This console utility comes bundled with multiboot disk Hiren's Boot CD.

    Hiren's Boot CD this is a disk with dozens of programs that help many computer scientists and system administrators. The main task MBRFix is to restore the Windows boot loader. Disk image Hiren's Boot CD can be downloaded from the official website www.hirensbootcd.org. Booting from Hiren's Boot CD, we will be taken to its boot menu.

    In this menu you need to select “ Mini Windows XP" and press Enter. By performing this action we will download portable version Windows XP with necessary utilities for diagnosing and repairing the system, including our utility MBRFix. Now let's go to " HBCD Menu» from a shortcut on the Desktop. Then in the menu " Programs"let's move on to the points " Partition/Boot/MBR/Commandline/MBRFix».

    This will allow us to open the console utility MBRFix. In the console window, enter the command MBRFix.exe /drive 0 fixmbr /win7 /yes

    This team will restore the boot record and bootloader, which will allow you to start Windows 7.

    Use disk Hiren's Boot CD with utility MBRFix It’s especially convenient if you don’t have the original disk with the seven.

    Let's sum it up

    In this material, we tried to look at all the ways to restore Windows 7 using the command line. Therefore, after reading this article, you can easily restore the functionality of your computer under Windows control 7.

    I would also like to note that if system files If the OS is severely damaged or erased, it will not be possible to restore the system or its bootloader. Therefore, if this is exactly the case for you, then make a backup all important information on the hard drive and reinstall Windows.

    We hope that our material will help you restore your system or its boot record, and will also allow you to avoid similar problems in the future or quickly solve them.

    Video on the topic

    Friends, many of you have repeatedly had problems loading the operating system and asked the question how to restore loading Windows 7 and make sure that the operating system boots normally. In this article, we will look at the most common ways to restore the Windows 7 bootloader, which help in most cases.

    1. Restore Windows 7 boot using the recovery tool

    Boot from your Windows version 7. The main thing is that the system bit size matches (32-bit or 64-bit). Also, it is desirable that the release coincides (Home, Professional, Ultimate).

    Instead of installing, select System Restore.

    Go to the System Recovery Options window and select the Startup Repair tool.

    After this, the recovery program will search for errors in the boot sector and boot Windows section 7 and, if detected, will try to correct them. After this, you will need to reboot the system and Windows 7 may boot normally.

    If you were unable to restore the boot using the Windows 7 recovery tool the first time, try repeating this process 1-2 more times. This often helps since a repair tool can't always fix multiple problems in one pass.

    2. Restore Windows 7 boot using the command line

    If you were unable to restore your Windows 7 boot using the automatic repair tool, then try using the command line. Boot into your version of Windows 7 and select System Restore instead of installing.

    Go to the System Recovery Options window and select the Command Prompt recovery tool.

    After this, a window with a black background will appear in which you will need to write several commands.

    Enter the following commands in turn:

    bootrec/fixmbr
    bootrec/fixboot
    bootsect /nt60 ALL /force /mbr
    exit

    Switching the language is done using the key combination “Alt” + “Shift”. After entering each command (line), you need to press the “Enter” key.

    Then restart your computer.

    After this, in most cases, problems associated with the boot sector and bootloader of Windows 7 will disappear and the operating system will boot normally.

    If after using the command line, Windows 7 still does not boot, then try using it again automatic tool boot recovery, as we discussed above.

    3. Restore Windows 7 boot with system reinstallation

    If you were unable to restore the operating system boot using the methods described above, you will most likely have to delete the partitions.

    Before reinstalling Windows 7, copy all important files from your hard drive to or. This can be done using any boot disk LiveCD. Please note that external drive or flash drive must be connected to the PC before booting from the LiveCD, otherwise they may not be detected.

    If you are unable to reinstall Windows 7 due to boot errors, remove all partitions from the disk using third party utility, for example, boot Acronis disk Disk Director. After that, try again by creating new partitions.

    If at reinstalling Windows 7 at the stage of setting up the disk (creating partitions, selecting a partition for installation) or when restarting the computer during the installation process, if you encounter the same boot errors, then launch the command line and run the commands that we discussed above.

  • Errors when using Disk Utilities
  • Incorrect activators
  • Installing Windows on an existing partition along with a bootloader

    • In order to prevent loading problems in the future, you need to determine what exactly led to the problem and not repeat these mistakes. If you are unable to restore Windows boot, or other errors occur with the installation and operation of the system, please visit the website http://esate.ru where you will find instructions for solving various problems with the operating system.

    Hello dear readers.

    Sometimes, as a result of various actions, it may happen that the computer refuses to enter the operating system. And in some cases, this is due to a malfunction of an important tool. The solution is to restore the Windows 7 bootloader.

    There are several main signs indicating the need to “return to life” the corresponding element of the operating system:

    Bootrec( )

    To return your computer to working condition, you need to perform a number of steps. In addition, for the procedure we will need installation Windows files. So we can’t cope with the corresponding data without a disk. We do the following:


    This command will show all the possible parameters it works with.

    Description of Bootrec keys( )

    Teams in the environment cmd.exe can be launched in the standard version, or with special additions. So, for example, if you write “ bootrec.exe /FixMbr", the program writes a boot record to the main partition. Moreover, the latter is compatible with Windows 7 and Vista. This will help restore the device's functionality. In addition, you can resort to this trick if there is a need to remove non-standard code in the corresponding segment. However, the existing partition table remains the same.

    If you use the key " /FixBoot", the program writes a new boot sector. It is also compatible with the above operating systems from Microsoft. This option is used in several cases:

      The boot file has been replaced with a non-standard one.

      It's damaged.

      After the seventh version or Vista, the previous build was posted. For example, after installing XP, the Windows NT boot loader is used.

    Interesting to know! The same effect can be achieved by using the program " bootsect.exe" It is also on disk. To do this, we write “ bootsect /NT60 SYS" A boot sector that is compatible with "" will appear. For detailed information you need to run the utility with the key " /help».

    When writing " bootrec.exe /ScanOs", the application scans all available disks for OS 7 and Vista. As a result, users receive a list of all systems found, even those not registered in the boot data storage.

    Using the key " /RebuildBcd"will start scanning all disks for installed operating systems. A list is compiled from which they can be added to the storage. Besides, this command will allow you to rebuild the database. However, before doing this, you definitely need to delete past data.

    The above utility has wide functionality. But it will not help if the system startup file is missing. In this case, you need to resort to another tool.

    It is worth noting that it works automatically. That is, users only need to get to certain tools, enter a command, and everything will be done independently - there is no need to do anything during the process itself.

    BCDboot( )

    This tool is designed to create or repair a bootloader located on the main partition. The program also allows you to transfer files between hard drives. Even if the system is not visible on the latter.

    To get started, just type “ bcdboot.exe C:\windows" The operation recovers damaged data, including storage files.

    The process has several parameters:

      Source – location of the directory in which it is located Windows distribution. In our case, this is a plastic disk or USB flash drive. This parameter is mandatory. The rest are indicated as necessary.

      « /I» — sets the language of the environment. If left unchanged, English is used.

      « /s"—indicates the drive letter where the files will be located. necessary files. By default, this is the location that is set by the BIOS or new system- UEFI.

      « /v"—the detailed work accounting mode starts.

      « /m» - combining the parameters of an existing record and a newly created one. All this is written to a new boot area.

    Returning after using Linux( )

    It’s worth imagining a situation where you previously had an operating system from Microsoft. And after Linux installations suddenly the first one stopped starting. This happened as a result of some errors.

    If you have after Ubuntu installations Windows doesn't work, don't panic right away. The problem can be solved simply.

    dd if=/dev/sda2 of=/linux.boot bs=512 count=1

    The code above allows you to copy the boot sector from the " sda2" in linux.boot.
