How to implement system restoration and image restoration in Win7 operating system? Let me give you a detailed introduction today, I hope everyone can help the operating system!
1. System Restore
Simply, when we When installing application software, hardware drivers, or system settings, Windows will first record the current system status to form a backup. In the future, if the system is not working properly, the entire system can be restored to the state at the time of backup. This function looks good, but in Windows XP and previous systems, there are not many people who have actually used this function. The reason is: restore needs to be done after system startup —— However, when the system can not When it is most needed to restore at startup, it becomes empty talk because the system cannot be started. To this end, the first thing many computer enthusiasts do after installing the system is to turn off this feature. Many friends and users do not know that this feature exists.
Windows 7 still retains this feature, but I believe that everyone will be reluctant to close it, because it can restore the system by repairing the CD — — completely solve the problem of the first restore after the start.
1) Creation of Restore Points
By default, Windows 7 automatically creates restore points in a timely manner, for example, when installing hardware drivers, when installing some software, and when making important settings to the system. It can also be created manually. Generally, if you think that some operations may affect the stability and security of the system, such as installing trial software and updating the unofficial driver, you need to manually create a restore point. The specific method is as follows:
(1) At the "Start" menu right-click "Computer", select the "Properties" command. Next, click “System Protection” from the window that opens. Here, we can observe that the "protect" status of the partition where Windows 7 is installed is "Open", that is, when the restore point is created manually or automatically, the partition is protected. In general, it is sufficient as long as this partition is in a protected state, as shown in FIG.
(2) Click the “Create” button to enter the name of the restore point in the dialog box that opens, and then click the “Create” button to create a restore point manually.
Note: The name of the restore point is best not to be entered for convenience. It should have certain mnemonic meanings, such as: " XX time to install XX", " XX time configuration XX" and so on. In this way, you can choose a restore point to restore the system.
2) Restore settings
System Restore is a very important and convenient feature, the biggest advantage is that it will not destroy the user's files, such as my documents, my pictures, my music, etc. To make it work better, you can make some simple settings.
System Restore only monitors the partition where Windows 7 is installed. If you want to monitor other partitions, please select it in Figure 7, click the “Configure” button, and select “Resume System Settings” in the dialog box that opens. Previous version of the file & rdquo;. Here, you can also control the hard disk space occupied by the restore function — — drag the corresponding slider, generally, you can choose about 10c /o. To turn off System Restore, simply select "Turn off system protection" here.
3)Recovering the system with a restore point
If you obviously feel that the system is not working properly because of a certain operation, or after a certain moment, the system is attacked by malware, use restore to fix it. It is a pretty good choice. Repairing your computer with a restore point can be done in the Windows 7 window or by repairing the CD.
4) In the Windows 7 window
Click on the "System Restore" in the dialog box of Figure 7. Next, select an existing restore point and click the “Next” button.
In this step, you must pay attention to the selection of the restore point, because the program installed after the restore point will not run, and some settings that we have manually performed on the system will no longer take effect. To solve this problem, please pay attention to the name of the restore point to distinguish, or click "Scan the affected program" to view, and strive to find a balance between the recovery system and try to ensure that the installed program and settings are effective.
5) Use the repair CD to restore
Use the repair CD (including the installation CD, security mode, etc.) to start the computer until the interface of Figure 6 appears, click & ldquo; System Restore & rdquo; Same as under the Windows 7 window.
2. Image Repair
Image Repair is one of the new features of Windows 7, and it works like the well-known Ghost. When creating, the entire partition is backed up as an image file, and when it is repaired, the image file is released to the specified hard disk partition.
Creating an image is done under the Windows 7 window, and restoring the system with an image can only be done by repairing the disc. This design concept takes care of both the ease of operation and the applicability. Creating an image is generally performed when the system is working properly. It is not necessary to use a repair disc to implement it, but it is simple and convenient to operate in the system window. In general, image restoration is mainly used to completely repair a damaged system, which is equivalent to re-installation, but the software installed before the image was created and the settings made to the system can be completely preserved. When the system is unable to start, and when it is most needed, the repair CD comes forward effectively to solve the drawbacks that other recovery measures (such as file recovery) cannot be implemented because the system cannot be started.
1) Create an image
Create an image in the Windows 7 window.
(1) Click “All Programs & Rarr;Maintain & Rarr; Backup or Restore & Rarr; Create System Image> to run the Backup Wizard in the "Start" menu.
(2) Choose where to save the backup. You can choose a shared location on a local hard drive or a removable hard drive on a partition, DVD, or LAN.
Tip: In order to ensure the convenience of recovery, it is recommended to store the backup on the local hard disk. Backups cannot be stored in a partition where Windows 7 is installed. Only other partitions can be selected.
(3) Select which partitions to back up. By default, the partition where Windows 7 is installed will be selected and cannot be modified, as shown in Figure 8. In general, selecting these two partitions is sufficient.
(4) Confirmation. In the next step, it will display the selected partitions to be backed up, the storage location of the backups, etc. in the form of a list. If it is correct, click “Start Backup", otherwise, click the back button in the upper left corner to reset. When completed, a file with the extension VHD is generated.
Tip: Because the partition file size of installing Windows 7 is relatively large, mostly 10GB or above, the backup takes a long time.
(5) Hidden partitions. In this example, the image file is stored in a partition on the local hard disk. To ensure the security of the image file, you can hide this partition. In the "Start" menu, right-click on "Computer" and select the "Manage" command. In the left window of the window that opens, expand “save →disk management”. Then right-click on the backup partition in the right window and select the “Change drive letter and path” command. Click the “Delete” button in the dialog that opens.
Note: This operation will not delete the partition, just delete the partition's drive letter (such as: E drive, F drive), so that it can not be displayed under the "Computer" window. In the future, when you use the image to recover your computer, you can display the partition letter: right-click the partition with the drive letter deleted, select “change the drive letter and path command ”, and then click “Add&rdquo in the dialog box that opens. ; button, then choose one.
(2) Repairing a computer with an image
Repairing a computer with an image can only be achieved by repairing the disc.
(1) Start the computer with the repair CD until the interface shown in Figure 6 appears, select “Image Repair”.
(2) Select the storage location of the image. First, it will recommend a recent backup for us. Xiaobian reminds everyone that unlike the restoration of the restore point, the image is generally only created once, so to directly select its recommended image.
Tip: If the image file is stored on the mobile hard disk or LAN shared location, you can click ““Advanced” on the recovery interface to make a selection. When specifying a LAN share location, the format of the path is: the folder name shared by the shared computer name.
(3) Extracting files from image files
In actual use, you may encounter a situation in which after the image is created, the user files are lost due to misoperation, and can be directly restored from the image without recovery. Extract the missing files?
According to Microsoft's description of the Windows 7 image file, the image file cannot be used for partial restore, but the author tried to show that some of the files in the image can be extracted. Thanks to Windows 7, the original ecological support for VHD files is provided.
The actual measurement shows that the image file generated when the image is created has the file extension VHD, and it is only necessary to load it as a virtual hard disk through the disk manager.
(1) The authority is released. On the author's computer, the image file storage location is N: WindowsImageBackupijiben-PCB
ackup 2009-10-14 185007, where bijiben-PC is the author's computer name, 2009-10-14 185007 indicates when creating the backup Date and number. When you enter these folders, you will get the prompt information related to the permissions, please click “unfree”, after the release, you will be able to access normally.
(2) Open the disk management. In the "Start" menu, right-click on "Computer" and select the "Manage" command. In the left window of the window that opens, expand “save →disk management”.
(3) Load the VHD file. Click the <;Operation→Add VHD" menu command and click the "Browse" button from the dialog that opens to find the VHD file to load. At this point, the image file is loaded as a virtual disk partition and the drive letter is automatically assigned.
Under the Explorer, double-click the virtual partition to observe the files, which are exactly the same as the partition folder structure and files before the backup.
3. Start repair
If the system can not be started, and can not find other reasons, please try “ start repair & rdquo;, select this option, the repair CD will automatically scan the files related to the startup, check Its integrity, reliability, and then replacement with normal files can generally solve the problem. During the repair process, you may be prompted to insert the Windows 7 installation CD as needed to replace the file.
The biggest benefit of this fix is that it does not destroy any of the user's files and does not affect the installed programs. When you fix a system that cannot be started, the first thing you should choose is it. If not, try the restore and image repair again.
4. Command prompt
Command prompt is a master of this savvy. Here, the author will present this problem in the form of an instance, so that you are among the best.
(1) Window interface scammed
Instance requirements: Windows 7 installed can not be started, try various repair measures are invalid, have to reinstall the system, how to back up the user files? In one instance, we will create a windowed environment with "out of nothing."
(1) Start the computer with the repair CD and select “ldquo command prompt” in the interface shown in Figure 6.
(2) In the Command Prompt window, enter the following command: notepad (this command is used to open the Notepad program).
(3) After the Notepad program is opened, just click the “File → Save As” menu command to open the windowed resource manager, as shown in Figure 9. It should be noted that the files that can be viewed at this time are only text files. To view all the files, select “All Files" in “Save Type”. The files that can be viewed can be copied to the partition of the hard disk.
Here, the system restore under the Win7 operating system. The image repair full Raiders is finished, do you understand? If you have any questions, please leave a message!
