迟早(Sooner)，每个人的操作系统(operating system)都会出现问题，无论版本如何。当事情变得艰难时，一些系统恢复(system recovery)工具会派上用场。Windows 7 有一些工具可以在系统不再正常运行时为您提供帮助。这些工具可用于以下场景：启动错误、升级失败或重启循环。
在本文中，我将与您分享可用工具的列表，解释它们的作用以及它们有用的场景。
系统恢复(System Recovery) 选项(Options)- 它们是什么以及何时使用它们
“系统恢复选项”('System Recovery Options')是一组 5 个工具，如下所列，可用于修复或恢复损坏的操作系统(operating system)：
-
启动修复 - 可用于扫描您的计算机并修复导致 Windows 无法正常启动的丢失或损坏的系统文件。如果您修改了 Windows 系统文件，或者如果您安装了修改了 Windows 系统文件的应用程序，您可以使用此工具，以使操作系统不再启动。
-
系统还原 - 可用于将 Windows 系统文件还原到较早时间点的状态，同时保持所有用户文件不变。当您想要恢复到您知道它正常工作的早期配置时，您可以使用系统还原。(System Restore)例如，如果您安装了多个应用程序并且突然遇到随机重启、启动失败和启动修复(Startup Repair)无法修复任何问题，那么解决问题的最快方法是使用系统还原(System Restore)。
注意：(NOTE:)为了使用系统还原(System Restore)，您必须至少有一个先前创建的系统还原点。有关此功能的更多信息将在即将发布的文章中发布。
-
系统映像恢复 - 可用于恢复系统映像。当其他一切都失败时，这可以解决您的问题。当启动修复(Startup Repair)和系统还原(System Restore)没有帮助时，请尝试使用系统映像恢复(System Image Recovery)工具。唯一的缺点是您只能恢复到创建系统映像时存在的文件、文件夹和应用程序。
注意：(NOTE:)要使用此工具，您必须有一个先前创建的系统映像文件。有关此功能的更多信息将在即将发布的文章中发布。
-
Windows 内存诊断 - 扫描您的计算机内存以查找错误。如果您的计算机在升级或更改 RAM 模块后随机冻结，最好使用Windows 内存诊断程序(Windows Memory Diagnostic)检查它们是否有错误。
-
命令提示符 - 高级用户可以使用它来执行与恢复相关的操作。这些操作只能由高级用户使用。如果您不确定自己在做什么，您的 Windows 7 可能会处于比以前更糟糕的状态。
有两种方法可以访问“系统恢复选项”('System Recovery Options')：从Windows 7安装DVD或直接从您的硬盘。我将从第一个场景开始。正如您将看到的，在这两种情况下都可以轻松找到“系统恢复选项” 。('System Recovery Options')
(Access System Recovery) 从安装 DVD(Installation DVD)访问系统恢复选项(Options)
第一步是将Windows 7安装DVD插入驱动器并(drive and boot)从中启动。选择您喜欢的语言，然后单击下一步(Next)。
注意：(NOTE:)为了从DVD引导，DVD 驱动器(DVD drive)必须是BIOS的(BIOS)“引导设备顺序”('Boot Device Order')部分中的第一个设备。根据您的主板制造商和 BIOS 型号，(motherboard manufacturer and BIOS model)此选项可能有不同的名称。
在下一个窗口中，单击“修复计算机”('Repair your computer')链接。
然后选择要修复的操作系统。(operating system)当您安装了多个操作系统(operating system)并且只有一个损坏时，此步骤很重要。单击(Click)下一步(Next)继续。
在新窗口中，您将看到所有“系统恢复选项”('System Recovery Options')。
(Access System Recovery) 从硬盘(Hard Disk)访问系统恢复选项(Options)
如果您没有Windows 7安装DVD，请不要担心。您仍然可以从第一次安装操作系统(operating system)时 Windows 7 自动创建的隐藏 100MB恢复分区访问(recovery partition)“系统恢复选项”('System Recovery Options')。
在下一次计算机重新启动(computer restart)时，在BIOS 信息(BIOS info)屏幕之后，按住键盘上的F8 键(F8 key)。很快您将看到一个“高级启动选项”('Advanced Boot Options)列表。从中选择名为“修复您的计算机”('Repair Your Computer')的第一个选项，然后按Enter键。
几秒钟后，将显示“系统安全选项”('System Security Options')窗口。选择您喜欢的键盘输入法(keyboard input method)，然后单击Next。
在下一个窗口中，选择一个用户名(user name)以登录到Windows 7。此外，如果您有该用户名(user name type)的密码，请在密码(Password)文本字段中输入。完成后，点击OK。
在新窗口中，您将看到可用于修复Windows 7的所有可用(Windows 7)“系统恢复选项”('System Recovery Options)。

An Overview of System Recovery Options for Windows 7
Sooner or later, everyone has problems with their operаting system, no matter the version. When the going gets tough, sоme system reсovery tools come in handy. Windows 7 has a few tools available which can help you when the syѕtem no longеr behaves as it is supрosed to. These tools can be used in the following scenarios: boot errors, upgrade failures or reboоt loops.
In this article I will share with you the list of available tools, explain what they do and the scenarios when they are helpful.
System Recovery Options - What they Are & When to Use them
The 'System Recovery Options' are a set of 5 tools, listed below, which can be used to repair or recover a damaged operating system:
-
Startup Repair - can be used to scan your computer and fix missing or damaged system files that prevent Windows from starting correctly. You can use this tool if you have modified Windows system files or if you installed applications which have modified Windows system files in such a way that the operating system doesn't start anymore.
-
System Restore - can be used to restore Windows system files to the state of an earlier point in time, while leaving all your user files untouched. You can use System Restore when you want to revert to an earlier configuration which you know it worked properly. For example, if you installed multiple applications and you are suddenly experiencing random restarts, boot failures and Startup Repair failed to fix anything, the quickest way to solve the problem is to use System Restore.
NOTE: In order to use System Restore you must have at least one system restore point previously created. More info about this feature will be published in upcoming articles.
-
System Image Recovery - can be used to restore a system image. When everything else fails, this can be the solution to your problems. When Startup Repair and System Restore are not helping, try to use the System Image Recovery tool. The only drawback is that you will revert only to the files, folders and applications that were present at the time you created the system image.
NOTE: In order to use this tool you must have a previously created system image file. More info about this feature will be published in upcoming articles.
-
Windows Memory Diagnostic - scans your computer's memory for errors. If your computer randomly freezes after you upgraded or changed the RAM modules, it is a good idea to use the Windows Memory Diagnostic to check them for errors.
-
Command Prompt - can be used by advanced users to perform recovery-related operations. These operations should only be used by advanced users. If you are not sure on what you are doing, you can end-up with your Windows 7 in a state which is a lot worse than before.
There are two ways of accessing the 'System Recovery Options': from the Windows 7 installation DVD or directly from your hard-disk. I will start with the first scenario. As you will see, finding the 'System Recovery Options' is easy in both cases.
Access System Recovery Options From The Installation DVD
The first step is to insert the Windows 7 installation DVD into your drive and boot from it. Select the language you prefer and click on Next.
NOTE: In order to boot from a DVD, the DVD drive has to be the first device in the 'Boot Device Order' section of your BIOS. Depending on your motherboard manufacturer and BIOS model this option can have different names.
In the next window click on the 'Repair your computer' link.
Then select the operating system that you want to repair. This step is important when you have multiple operating systems installed and only one is damaged. Click on Next to continue.
In the new window you will see all the 'System Recovery Options'.
Access System Recovery Options From Your Hard Disk
If you don't have a Windows 7 installation DVD, don't worry. You can still access the 'System Recovery Options' from a hidden 100MB recovery partition that Windows 7 automatically creates when you first installed the operating system.
At the next computer restart, right after the BIOS info screen, press and hold the F8 key from your keyboard. Shortly you will see a list of 'Advanced Boot Options. From it, select the first option named 'Repair Your Computer' and press the Enter key.
After a few seconds a 'System Security Options' window will show up. Select the keyboard input method that you prefer and click on Next.
In the next window, select a user name to log on to Windows 7. Also, if you have a password for that user name type it in the Password text field. When done, click on OK.
In the new window you will see all the available 'System Recovery Options that you can use to repair Windows 7.
Conclusion
In this article I covered the basic information about the available 'System Recovery Options' in Windows 7, as well as when to use each of them. In future articles I will talk about each of these tools, one by one. So, stay tuned for future articles.
Until then, don't hesitate to share with us your questions & scenarios when these tools proved to be useful to you.
