usb闪存驱动器
If you’d like to install Windows but don’t have a DVD drive, it’s easy enough tocreate a bootable USB flash drive with the right installation media. Here’s how to get it done for Windows 10, 8, or 7.
如果您想安装Windows但没有DVD驱动器，那么使用正确的安装介质创建可引导的USB闪存驱动器就很容易了。 在Windows 10、8或7上完成操作的方法如下。
In this guide, we’ll be making a simple USBdrive that acts just like an installation DVD, and lets you install one version of Windows. If you’d like to create a USB drive from which you can install multiple versions of Windows, you’ll want to follow these instructionsinstead.
在本指南中，我们将制作一个简单的USB驱动器，其作用类似于安装DVD，并允许您安装一个版本的Windows。 如果您想创建一个USB驱动器，可以从中安装多个版本的Windows，请改用这些说明 。
第一步：为Windows安装介质创建或下载ISO(Step One: Create or Download an ISO for the Windows Installation Media)
Before you can create your USB installation drive, you’ll need to have your Windows installation media available as an ISO file. If you already have an installation DVD, you can use it to create an ISO file using ImgBurn, a handy little free utility that’s been around forever. If you don’t have Windows installation DVD, you can download ISO files for Windows 10, 8, or 7 directly from Microsoft.
在创建USB安装驱动器之前，您需要将Windows安装介质作为ISO文件提供。 如果您已经有安装DVD，则可以使用它使用ImgBurn创建ISO文件，ImgBurn是一个方便易用的免费实用工具，已经存在了很长时间。 如果没有Windows安装DVD，则可以直接从Microsoft下载Windows 10、8或7的ISO文件 。
You’ll also need a minimum of a 4GB flash drive to create your installer. Be sure to copy anything you want off of it, because this process will erase it.Once you have both your ISO and flash drive inhand, you’re ready to continue.
您还需要至少4GB的闪存驱动器来创建安装程序。 确保从中复制任何所需的内容，因为此过程将删除它。 拥有ISO和闪存驱动器之后，就可以继续了。
第二步：使用Windows USB / DVD下载工具创建安装USB驱动器(Step Two: Create Your Installation USB Drive with theWindows USB/DVD Download Tool)
With your ISO file saved to your computer, your next step is to download and install the Windows USB/DVD Download Tool. The description on that page, on the actual download page, and on the tool itself talk a lot about Windows 7 and even XP. Don’t let that worry you. The tool works just fine for Windows 7, 8, and even 10.
将ISO文件保存到计算机后，下一步就是下载并安装Windows USB / DVD下载工具 。 该页面上的说明，实际下载页面上以及该工具本身上的内容都涉及Windows 7甚至XP。 不要让那让你担心。 该工具适用于Windows 7、8甚至10。
Once you’ve got the tool installed, creating your USB installation drive isa pretty straightforward process. Run the tool and give it permission to make changes to your PC. Click “Browse” tolocate your Windows ISO file and then click “Next.”
安装完工具后，创建USB安装驱动器是一个非常简单的过程。 运行该工具并授予其对PC进行更改的权限。 单击“浏览”以找到Windows ISO文件，然后单击“下一步”。
On the next page, click “USB device.” The tool can also burn the ISO to a DVD if you need that option.
在下一页上，单击“ USB设备”。 如果需要，该工具还可以将ISO刻录到DVD。
Use the drop-down menu to choose the USB flash drive you want to use. If you haven’t inserted it yet, do that now, and then click the Refresh button. Once you’ve got the right drive selected, click “Begin copying.”
使用下拉菜单选择要使用的USB闪存盘。 如果尚未插入，请立即执行，然后单击刷新按钮。 选择正确的驱动器后，单击“开始复制”。
If your USB drive has anything already on it, you’ll next see a warning that it will be formatted and you’ll lose any data stored on the drive. Go ahead and click “Erase USB Device.” If you started with a newly-formatted USB drive, you won’t see this warning.
如果您的USB驱动器上已经有任何东西，那么您接下来将看到一条警告，指出该驱动器将被格式化，并且将丢失该驱动器上存储的所有数据。 继续，然后单击“擦除USB设备”。 如果您使用新格式化的USB驱动器启动，则不会看到此警告。
Now you just have to wait for the process to complete, which usuallytakes 15-20 minutes. The drive will be formatted and files copied to the flash drive.
现在，您只需要等待该过程完成即可，通常需要15到20分钟。 该驱动器将被格式化并将文件复制到闪存驱动器。
When the process is finished, you can close the download tool.
该过程完成后，您可以关闭下载工具。
If you take a look at the flash drive in File Explorer, you’ll be able to see the same files that you would if you opened the installation DVD.
如果您在File Explorer中查看闪存驱动器，将可以看到与打开安装DVD相同的文件。
And now that you have your installation USB drive, you can use it to start the computer on which you want to install Windows. You may have to fiddle with the BIOS on the computer to allow it to boot from USB or to change the boot order so that it will boot from the USB first. You may even be able to use the disk on computers that don’t support booting from USB, but you’ll need to take additional steps to create a bootable CD.
现在，您已经拥有安装的USB驱动器，您可以使用它来启动要安装Windows的计算机。 您可能必须摆弄计算机上的BIOS ，以使其从USB引导或更改引导顺序，以便它首先从USB引导。 您甚至可以在不支持从USB引导的计算机上使用该磁盘，但是您需要采取其他步骤来创建可引导CD。
