在Internet 上(Internet)，您可能会找到大量关于如何在计算机上安装Windows 8的指南，但很少有关于如何创建双启动设置(boot setup)并使其与Windows 7、Windows Vista 或 Windows XP(Windows Vista or Windows XP)一起运行的指南。这就是为什么我们决定帮助想要创建多重引导设置并分享安装(setup and share)Windows 8和早期版本的Windows所需的步骤的用户。不要犹豫，阅读整篇文章，避免问题和问题。
步骤 1(Step 1)。了解新的 Windows 8(New Windows 8) 启动管理器(Boot Manager)
首先，您需要了解Windows 8中包含的新引导管理器(boot manager)。它是Windows 8(Windows 8)中最重要的创新之一。新的引导管理器(boot manager)不仅看起来不同，而且：
- 它是触摸友好的，可以在平板电脑和触摸显示器上轻松使用；
- 它允许您选择在设定时间(set time)后启动的默认操作系统；
- 它提供了比Windows(Windows)早期版本的引导管理器更多的工具和功能；
- 加载时间比其他启动管理器要长，但有助于加快Windows 8的启动过程。正如您将亲身体验的那样，Windows 8的启动时间是所有Windows版本中最快的；
- 如果您选择启动到Windows 7或其他先前版本的Windows，它将重新启动您的系统并加载适合该版本Windows的(Windows)启动管理器(boot manager appropriate)。
由于它是如此不同，它与早期版本的Windows(Windows)的引导管理器不兼容。
步骤 2(Step 2)。首先安装其他版本的Windows(Windows First) -最后安装Windows 8(Leave Windows 8)
由于Windows 8 启动管理器(boot manager)如此不同，因此在多启动配置中，Windows 8 应始终最后安装(Windows 8 should always be installed last)。如果您先安装它，然后再安装其他版本的Windows，新的启动管理器(boot manager)将被覆盖，您将无法启动到Windows 8。然后，您需要使用Windows 8安装光盘修复(installation disc)启动管理器(boot manager)或使用一些第三方软件来管理和修复您的启动项。
您可以尝试支持Windows 8的(Windows 8)EasyBCD 2.2 Beta。如果您发现其他适用于Windows 8的启动管理器，请不要犹豫，在评论中分享它们。
步骤 3(Step 3)。创建仅适用于Windows 8的(Windows 8)分区(Partition Just)
安装完其他版本的Windows后，您应该对硬盘进行分区并为Windows 8创建一个新分区。确保此分区的大小至少为 20 - 25 GB。如果您打算在Windows 8中安装大量应用程序，请不要犹豫，让分区更大。
您可以使用许多工具来创建此分区。如果您更喜欢Windows中包含的工具，请不要犹豫，使用磁盘管理(Disk Management)工具。要了解如何使用它，请阅读本教程：如何使用磁盘管理实用程序管理您的(Disk Management Utility)磁盘(Disks)。
步骤 4. 安装 Windows 8
只有在您安装了其他版本的Windows并为(Windows)Windows 8创建分区后，才能继续安装Windows 8。
获取安装光盘(installation disc)，从中启动并启动Windows 8安装程序。请遵循我们的详细安装指南(installation guide)：如何在您的计算机上安装(Your Computer)Windows 8 RTM。
对于多重引导设置(multiboot setup)，步骤与该指南中的相同。唯一的区别是，当您被要求选择安装Windows 8的位置时，请选择您创建的分区，并确保您没有选择安装其他操作系统的分区。
第 5 步(Step 5)：自定义默认引导操作系统(Default Boot Operating System)
安装 Windows 8 后，它被设置为您的默认启动(default boot) 操作系统(operating system)。如果您打算将其用作您的主要操作系统(operating system)，那没关系。
但是，如果您打算将其用作辅助操作系统(operating system)，则最好更改默认值。您可以使用Windows中的系统配置实用程序(System Configuration utility)来更改默认引导(default boot)操作系统(operating system)。
您还可以使用第三方工具(party tool)，例如EasyBCD 2.2 Beta或 Windows 8 启动管理器。
结论
正如您从本指南中看到的那样，安装 Windows 8 和Windows 7、Windows Vista 或 Windows XP(Windows Vista or Windows XP)可以相对轻松地完成。但是，您确实需要相当多的时间才能完成所有工作，并且您需要注意操作系统的安装顺序。
How to Dual Boot Windows 8 with Windows 7, Windows Vista or Windows XP
On the Internet yоu may find plenty of guides on how to install Windows 8 on your computer but very few guides on how to create a duаl boot setυp and have it rυn alongside Windows 7, Windows Vista or Wіndows XP. That's why we decided to help users who want to create a multiboot setup and share the steps required to install Windows 8 alongside earlier versions of Windows. Don't hesitate to read the whole article and save yourself from problems and issues.
Step 1. Learn About The New Windows 8 Boot Manager
First, you need to learn about the new boot manager included with Windows 8. It is one of the most important novelties in Windows 8. The new boot manager not only looks different but:
- It is touch friendly and can be used easily on tablets and displays with touch;
- It allows you to choose the default operating system to boot into after a set time;
- It provides more tools and features than the boot managers of earlier versions of Windows;
- It takes longer to load than other boot managers but facilitates a faster boot procedure for Windows 8. As you will experience yourself, Windows 8 has the fastest boot time of all versions of Windows;
- If you choose to boot into Windows 7 or another previous version of Windows, it will reboot your system and load the boot manager appropriate for that version of Windows.
Since it is so different it is incompatible with the boot managers from earlier versions of Windows.
Step 2. Install Other Versions of Windows First - Leave Windows 8 Last
Since the Windows 8 boot manager is so different, in a multi-boot configuration, Windows 8 should always be installed last. If you install it first and then other versions of Windows, the new boot manager will be overwritten and you won't be able to boot into Windows 8. Then, you need to repair the boot manager with the Windows 8 installation disc or use some third-party software to manage and fix your boot entries.
You can try EasyBCD 2.2 Beta which provides support for Windows 8. If you find other boot managers that work with Windows 8, don't hesitate to share them in the comments.
Step 3. Create a Partition Just for Windows 8
Once you are done installing other versions of Windows, you should partition your hard drive and create a new partition just for Windows 8. Make sure that this partition is at least 20 - 25 GB in size. If you plan to install lots of applications in Windows 8, don't hesitate to make the partition bigger.
There are many tools you can use to create this partition. If you prefer the tools included in Windows, then don't hesitate to use the Disk Management tool. To learn how to use it, read this tutorial: How to Manage Your Disks using the Disk Management Utility.
Step 4. Install Windows 8
Only after you install the other versions of Windows and create the partition for Windows 8, go ahead and install Windows 8.
Get the installation disc, boot from it and start the Windows 8 setup. Follow our detailed installation guide: How to Install Windows 8 RTM on Your Computer.
For a multiboot setup, the steps are the same as in that guide. The only difference is that when you are asked to select where to install Windows 8, select the partition that you created and make sure you don't select the partitions where other operating systems are installed.
Step 5: Customize the Default Boot Operating System
After you install Windows 8, it is set as your default boot operating system. If you plan to use it as your main operating system, that's OK.
However, if you plan to use it as a secondary operating system, it is best to change the default. You can use the System Configuration utility in Windows to change the default boot operating system.
You can also use a third party tool like EasyBCD 2.2 Beta or the Windows 8 boot manager.
Conclusion
As you can see from this guide, installing Windows 8 alongside Windows 7, Windows Vista or Windows XP can be done with relative ease. However, you do need quite a bit of time to get everything done and you need to pay attention to the order in which operating systems are installed.
