CD 安装程序的日子已经一去不复返了。现在您可以使用更方便的工具（如USB）来安装或修复操作系统。我们将向您展示如何使用它来重新启动和修复 PC。
默认情况下，Windows会在启动过程中尝试检测任何错误，如果出现问题，通常会自动启动到安全模式。然而，虽然Windows 10具有强大的自我恢复工具，但它并不是万无一失的。
可启动 USB
您想要一个可启动的USB(USB)是有充分理由的。如果您的 PC 崩溃并且无法自行启动，您可以使用USB驱动器作为恢复系统。
这就像拥有一个全新的便携式操作系统，而无需经历完整的Windows安装的麻烦。您可以在任何计算机上使用您喜欢的设置和工具。有些人使用可启动USB(USBs)来提供针对键盘记录器和病毒的安全性。
外部硬盘驱动器也可以代替标准USB工作。
要求
您需要具备以下条件才能继续：
- 访问Windows DiskPart或第三方等效项
- 具有至少 8GB 存储空间的 USB 3.0
- 您要安装或用于修复的操作系统的ISO文件(ISO)
您可以直接从 Microsoft 网站下载 Windows 操作系统(download the Windows OS straight from Microsoft’s website)。但是您将需要一个产品密钥来激活其所有功能并合法拥有操作系统。
创建可启动驱动器
使用DiskPart和命令提示符，您可以创建安装了任何操作系统的可引导 USB。
将(Insert)可启动的USB闪存驱动器插入您的 PC 或笔记本电脑。通过单击Start，键入cmd然后右键单击Command Prompt并选择Run as Administrator打开管理员命令提示符(Command Prompt)。
键入DISKPART并按Enter。这将启动Windows DiskPart。
在下一个命令行上，键入LIST DISK以查看可用的存储设备。确定(Identify)哪个存储设备指的是您插入的USB驱动器。(USB)
如果你不确定，你可以点击Start并输入Disk Management。然后点击Create and Format Hard Disk Partitions。在Disk Management中，查找下方列出了Removable的磁盘#。(Removable)您也可以通过查看驱动器的大小来确认。
键入命令SEL DISK 1，其中“1”是USB驱动器的相应位置。如果USB驱动器位于Disk 2上，则键入SEL DISK 2。
在新行上，输入
CLEAN并按Enter。此命令将删除USB的内容，因此请确保您已备份所有文件。
现在我们对驱动器进行分区。我们将输入一系列命令。确保(Make)在每个之后按Enter 。类型CREATE PARTITION PRIMARY。然后键入LIST PAR以选择主分区。要激活分区，请键入ACTIVE。
我们可以通过键入FORMAT FS=FAT32 LABEL=“ABC” QUICK OVERRIDE来格式化 USB，其中“ABC”是您要为USB驱动器指定的名称。您还可以通过输入代码ASSIGN自动为您的(ASSIGN)USB分配驱动器号。
完成后，您可以退出DiskPart和Command Prompt。将Windows ISO(Windows ISO)
文件拖放到可启动驱动器(Drag)。
更改引导顺序
接下来，如果要使用可启动USB ，则需要更改 PC 上的启动顺序(change the boot order on your PC)。您可以通过进入BIOS设置来执行此操作。您将需要搜索引导菜单并查找引导(Boot)或引导顺序(Boot Order)（每台 PC 都不同）。
在那里，您可以选择您的USB驱动器并命令您的计算机从该设备启动。您可以通过移动引导驱动器的顺序来永久更改引导顺序。这样，如果需要，您可以随时从USB驱动器启动计算机。
按ESC(ESC)退出 BIOS 。当计算机启动时，它应该会检测到连接到您的计算机的新可启动USB驱动器并开始加载操作系统。
此时，您可以使用它来修复您当前的操作系统或安装新的操作系统副本（如果您愿意）。享受！
How to Make a Bootable USB and Save Your PC
Gone are the days of СD installers. Now you can use more convenient tools like a USB to install or repair an operating system. We’ll show you how you can use one to reboot and repair a PC.
By default, Windows will try to detect any errors during startup and will normally automatically boot to safe mode if there are issues. However, while Windows 10 has robust self-recovery tools, it’s not bullet-proof.
Bootable
USBs
There’s a good reason why you’d want a bootable USB lying around. In the event that your PC crashes and would no longer boot on its own, you can use the USB drive as a recovery system.
It’s like having a fresh, portable OS with you without having to go through the hassle of a full Windows installation. You can have your preferred settings and tools available on any computer. Some use bootable USBs for the security it offers against keyloggers and viruses.
An external hard
drive would also work in place of a standard USB.
Requirements
You will need to
have the following in order to proceed:
- Access to Windows DiskPart or a third-party equivalent
- USB 3.0 with at least 8GB of storage
- An ISO file of the OS you want to install or use to repair
You can download the Windows OS straight from Microsoft’s website. But you will need a product key to activate all its features and own the OS legally.
Create
a Bootable Drive
With DiskPart and
the command prompt, you can create a bootable USB with any operating system
installed.
Insert a bootable USB flash drive into your PC or laptop. Open an administrator Command Prompt by clicking on Start, typing cmd and then right-clicking on Command Prompt and choosing Run as Administrator.
Type DISKPART and hit Enter. This will launch Windows DiskPart.
On the next command line, type LIST DISK to view the available storage devices. Identify which storage device is referring to the USB drive you’ve plugged in.
If you’re not sure, you can click on Start and type in Disk Management. Then click on Create and Format Hard Disk Partitions. In Disk Management, look for the disk # that has Removable listed underneath. You can also confirm by looking at the size of the drive.
Type the command SEL DISK 1 where “1” is the
corresponding location of the USB drive. If the USB drive is located on Disk 2,
then type SEL DISK 2 instead.
On a new line, type
CLEAN and hit Enter. This command will remove the content of the USB so make sure
you’ve backed up all your files.
Now we partition
the drive. We’ll be entering a series of commands. Make sure to press Enter after each one. Type CREATE PARTITION PRIMARY. Then type LIST PAR to select the main partition.
To activate the partition, type ACTIVE.
We can format the USB by typing FORMAT FS=FAT32 LABEL=“ABC” QUICK OVERRIDE where “ABC” is the name you’d like to designate for your USB drive. You can also automatically assign a drive letter to your USB by entering the code ASSIGN.
Once you’re done,
you can exit both DiskPart and Command Prompt. Drag and drop the Windows ISO
file to your bootable drive.
Changing
the Boot Order
Next, you need to change the boot order on your PC if you want to use your bootable USB. You can do this by going to your BIOS settings. You will need to search through the boot menu and look for Boot or Boot Order (every PC is different).
Once there, you can select your USB drive and order your computer to boot from that device. You can permanently change the boot order by moving the order of the boot drives. This way, you can always have your computer boot from your USB drive if you want.
Exit the BIOS by hitting ESC. As the computer boots up, it should detect the new bootable USB drive connected to your machine and begin loading the operating system.
At this point, you can use it to repair your current operating system or install a fresh copy of the OS if you like. Enjoy!
