如何在同一台PC上双启动Windows 7和Windows 8
If you want to try out the new Windows 8 but don’t have a CPU that supports virtualization, check out our guide on how to get all the goodness of Windows 8 along side Windows 7 by dual booting.
如果您想试用新的Windows 8但没有支持虚拟化的CPU，请查看我们的指南，了解如何通过双启动将Windows 8与Windows 7结合使用。
The scenario: you are in a situation where you have Windows 7 installed and you really want to try out Windows 8, but your PC does not support virtualization and you don’t want to have to format since Windows 8 is still in pre-beta and the chances are that there are some things that are broken. The only option you have here is to dual boot. The only thing that is required in order to dual boot is a hard drive with at least 20 Gigs of free space, it will work with a bit less but this is the minimum we recommend.
场景：您已经安装了Windows 7，并且确实要尝试Windows 8，但您的PC不支持虚拟化，并且您不想格式化，因为Windows 8仍处于beta版而且有可能有些事情被打破了。 您这里唯一的选择是双重引导。 要进行双重引导，唯一需要的是具有至少20 Gigs可用空间的硬盘驱动器，它的工作空间要少一些，但这是我们建议的最小值。
双重启动Windows 7和Windows 8 (Dual Booting Windows 7 and Windows 8)
To get started we need to logically separate those 20 Gigs from the space that Windows 7 is currently using, to do this we need to create a new partition. You can do this in the disk management MMC snap-in, to launch the snap-in press the Windows Key + R to launch a run box, type “diskmgmt.msc” into the run box.
首先，我们需要从Windows 7当前使用的空间中将这20个Gig逻辑上分开，为此，我们需要创建一个新分区。 您可以在磁盘管理MMC管理单元中执行此操作，要启动管理单元，请按Windows键+ R启动运行框，在运行框中键入“ diskmgmt.msc”。
Once you press enter or click the ok button, a MMC will load with the disk management snap-in pre-loaded. From here you can get a nice overview of your hard drives.
一旦按Enter或单击“确定”按钮，MMC就会加载磁盘管理管理单元。 从这里您可以很好地了解硬盘驱动器。
A dialog box will appear asking you how much you want to shrink the drive by. It asks you how much you would like to shrink in megabytes, so remember that there is 1024 megabytes in a gig so in our example we shrink 20 gigs which is20480 megabytes because 20*1024=20480.
将出现一个对话框，询问您要将驱动器缩小多少。 它询问您要缩小多少兆字节，因此请记住，一个演出中有1024兆字节，因此在我们的示例中，我们缩小20个演出即20480兆字节，因为20 * 1024 = 20480。
Once you click the shrink button Windows will shrink your drive. Once it has completed shrinking your partition, the Disk Manager will display this new space with a black header meaning it is an empty partition, you now need to give it a file system. To format the drive with a file system right click on the black space and select “New Simple Volume”.
单击缩小按钮后，Windows将缩小驱动器。 完成分区的收缩后，磁盘管理器将显示带有黑色标题的新空间，这意味着它是一个空分区，现在需要为其提供文件系统。 要使用文件系统格式化驱动器，请在空白处单击鼠标右键，然后选择“新建简单卷”。
A wizard will launch this is going to take us through all the steps we need to format the drive. On the welcome screen you can just select next to be asked how much of the unallocated space you want to use, we recommend you leave the default which will use all the space you set aside if you alter this it may result in some space going to waste.
将启动一个向导，它将引导我们完成格式化驱动器所需的所有步骤。 在欢迎屏幕上，您可以仅选择下一步，然后询问您要使用多少未分配空间，我们建议您保留默认值，如果您更改此设置，它将使用您留出的所有空间，这可能会导致一些空间浪费。
In the next dialog it asks you to assign it a drive letter, you can accept the defaults and click next.
在下一个对话框中，要求您为其分配驱动器号，您可以接受默认值，然后单击“下一步”。
On the format partition step of the wizard you can leave everything at defaults accept for the Volume Label which you should change to something memorable for example “Windows 8” this is important as this is the partition you will have to select at install time.
在向导的格式分区步骤中，您可以将卷标的默认设置保留为默认值，应将其更改为令人难忘的名称，例如“ Windows 8”，这很重要，因为这是您在安装时必须选择的分区。
Click next and finish to initiate the format. Once the format is finished the once black header will now be blue and you are ready to install Windows 8.
单击下一步并完成以启动格式。 格式化完成后，曾经的黑色标题现在将变为蓝色，您可以安装Windows 8了。
安装 (Installation)
