在许多情况下，您可能希望使用USB 闪存(USB flash)驱动器启动计算机。可能是因为您需要在 PC 上安装Windows，或者可能是因为您想尝试您最喜欢的Linux 发行(Linux distribution)版的最新版本。无论您出于何种原因，以下是使用可启动USB 闪存(USB flash)驱动器启动计算机的三种不同方法：
1. 使用 Windows 10 的设置让您的PC(PC boot)从USB 闪存(USB flash)驱动器启动
首先将可启动USB 闪存(USB flash)驱动器插入计算机上的USB 端口(USB port)。然后，打开设置应用程序并(Settings app and head)前往更新和安全(Update & Security)。
选择左侧的恢复(Recovery)，然后在窗口右侧滚动，直到找到高级启动(Advanced startup)部分。在其中，单击或点击立即重新启动(Restart now)按钮。
Windows 10 重新启动，然后显示一个屏幕，您可以在其中“选择一个选项(Choose an option)”。单击或点击“使用设备”。("Use a device.")
接下来，您应该会看到您的计算机可以启动的所有设备的列表，包括您插入的USB 闪存驱动器。(USB flash)单击(Click)或点击它。
然后，您的计算机将重新启动并从您选择的USB 闪存驱动器启动。(USB flash)
2. 使用Boot Menu选择USB 闪存(USB flash)驱动器作为第一个引导选项(boot option)
如果幸运的话，无论您的 PC 上安装了何种操作系统，从(operating system)USB 闪存(USB flash)驱动器启动所需要做的就是从BIOS的(BIOS)启动菜单(Boot Menu)中选择USB 闪存(USB flash)驱动器。确保(Make)您的USB 闪存(USB flash)驱动器可启动，然后将其插入计算机上的任何USB 端口(USB port)。
接下来，打开计算机电源（如果已打开，则重新启动）。开机后，当BIOS/UEFI screen出现时，按右键访问引导菜单。(Boot Menu)大多数 PC 制造商为此使用 F8、F9、F10 或 F11 键(F10 or F11 keys)，并且许多计算机在您开机后会立即显示启动菜单(Boot Menu)键。但是，如果您无法识别正确的，请查看您的计算机主板或设备制造商(device manufacturer)的文档。Boot Menu 访问密钥(access key)应在其用户手册中提及。
启动菜单(Boot Menu)出现在屏幕上后，使用它选择要从中启动的USB 闪存(USB flash)驱动器，然后按键盘上的Enter 。请注意，USB闪存驱动器可以使用不同的名称，具体取决于PC 或主板制造商(PC or motherboard manufacturer)的需求。有些将其列为Removable Device，有些列为USB-HDD等。
按下Enter后，计算机应从USB 闪存(USB flash)驱动器启动。
3. 使用BIOS/UEFI更改启动设备顺序并将USB 闪存(USB flash)驱动器移动到列表顶部
首先访问您的BIOS/UEFI。您应该可以在打开 PC 电源后立即按右键（组合键）来执行此操作。虽然您的PC 或主板(PC or motherboard)的制造商可以选择它想让您按的任何键，但常用的键包括Delete、 F1、 F2 、F10和F12。如果这些都不起作用，您可以在PC 或主板(PC or motherboard)的手册中找到正确的按键。
如果您的 PC 具有UEFI（一种较新的BIOS），它可能会启动得太快，以至于您没有时间按任何键来访问它。在这种情况下，请按照此处所述的步骤操作：如何在Windows平板电脑、笔记本电脑和敞篷车上访问UEFI BIOS 固件。(UEFI BIOS Firmware)
进入BIOS/UEFI后，浏览其配置选项，直到找到名为Boot或类似页面的页面。在那里您应该看到计算机使用的引导顺序(boot order)。在此列表中，您必须选择USB 闪存(USB flash)驱动器作为用于引导的第一个设备。请记住(Remember)，USB 选项(USB option)可以在您的 PC 上以不同的方式命名：检查可移动设备、USB-HDD(Removable Devices, USB-HDD)或类似名称。通常使用键盘键(keyboard keys)+, -, F5或F6将USB 闪存驱动器移动到(USB flash)引导列表(boot list)的顶部。您的BIOS/UEFI 应显示有关此主题的一些有用信息。
选择USB 闪存(USB flash)驱动器作为第一个启动选项(boot option)后，保存设置（通常通过按键盘上的F10完成）并(F10)退出(Exit) BIOS/UEFI。您的计算机应重新启动，然后自动从USB 闪存(USB flash)驱动器启动。
重要提示：(IMPORTANT:)如果您的计算机使用UEFI，您可能无法进行之前的设置。在这种情况下，您必须首先（暂时）禁用安全启动(Secure Boot)选项。根据制造商的需要，此选项也可以有不同的名称：Legacy Boot或Legacy Support、CSM或Launch CSM，等等。选择(Choose)启用以Legacy开头或名称中包含CSM的选项。
您最喜欢从USB 闪存(USB flash)驱动器启动的方法是什么？
现在您知道了使用USB 闪存(USB flash)驱动器启动计算机的三种不同方法。你最喜欢他们中的哪(Which)一个？您是使用Windows 10内置的选项，还是更喜欢从BIOS/UEFI中进行操作？您(Did)是否设法从USB 驱动器(USB drive)启动 PC ？如果没有，出了什么问题？在下面发表评论(Comment)，让我们讨论。
3 ways to boot your Windows 10 PC from a USB flash drive -
There are many situations in which you might want to boot your computеr using a USB flash drive. Maybe because you need to install Windows on your PС or maybe becauѕe you want to try the latest version of your favorite Linux distribution. Whateνer reasons you might have, here are three different ways to use a bootable USB flash drіve to start yoυr computеr:
1. Use Windows 10's Settings to make your PC boot from a USB flash drive
Start by plugging in the bootable USB flash drive to a USB port on your computer. Then, open the Settings app and head to Update & Security.
Select Recovery on the left, and then scroll on the right side of the window until you find the Advanced startup section. In it, click or tap the Restart now button.
Windows 10 restarts and then shows a screen where you can "Choose an option." Click or tap on "Use a device."
Next, you should see a list of all the devices that your computer can boot from, including the USB flash drive that you plugged in. Click or tap on it.
Your computer then restarts and boots from the USB flash drive that you chose.
2. Use the Boot Menu to select the USB flash drive as the first boot option
If you are lucky, then all that you must do to boot from a USB flash drive, regardless of the operating system installed on your PC, is choose the USB flash drive from the Boot Menu of your BIOS. Make sure that your USB flash drive is bootable and then plug it into any USB port on your computer.
Next, power on your computer (or restart it if it was on). Immediately after powering it on, when the BIOS/UEFI screen appears, access the Boot Menu by pressing the right key(s) for it. Most PC manufacturers use the F8, F9, F10 or F11 keys for that, and many computers show the Boot Menu key(s) right after you power them on. However, if you cannot identify the right one, check the documentation for your computer's motherboard, or device manufacturer. The Boot Menu access key(s) should be mentioned in their user manuals.
Once the Boot Menu appears on your screen, use it to select the USB flash drive from which you want to boot and press Enter on your keyboard. Note that the USB flash drive can bear different names depending on what the PC or motherboard manufacturer wanted. Some list it as Removable Device, some as USB-HDD and so on.
Once you have pressed Enter, the computer should boot from the USB flash drive.
3. Use the BIOS/UEFI to change the boot devices order and move the USB flash drive to the top of the list
Start by accessing your BIOS/UEFI. You should be able to do that by pressing the right key (combination) immediately after you power on your PC. Although the manufacturer of your PC or motherboard can choose whatever key it wants you to press, commonly used keys include Delete, F1, F2, F10, and F12. If none of these works, you can find the right key to press in the manual of your PC or motherboard.
If your PC has UEFI (a newer type of BIOS), it may boot so fast that you do not have time to press any key to access it. In such a situation, follow the steps described here: How to access the UEFI BIOS Firmware on Windows tablets, laptops and convertibles.
Once you have entered the BIOS/UEFI, browse through its configuration options until you find a page called Boot or similar. There you should see the boot order used by your computer. In this list, you must choose the USB flash drive to be the first device used for booting. Remember that the USB option can be named differently on your PC: check for Removable Devices, USB-HDD or similar names. Moving the USB flash drive to the top of the boot list is usually done using the keyboard keys +, -, F5 or F6. Your BIOS/UEFI should display some helpful information about this topic.
Once you have chosen the USB flash drive as the first boot option, save your settings (usually done by pressing F10 on your keyboard) and Exit BIOS/UEFI. Your computer should restart and then automatically boot from the USB flash drive.
IMPORTANT: If your computer uses UEFI, you might not be able to make the previous settings. In that case, you must first disable (temporarily) the Secure Boot option. This option can also have different names depending on what the manufacturer wanted: Legacy Boot or Legacy Support, CSM or Launch CSM, and so on. Choose to enable the options that start with Legacy or which have CSM in their names.
Which is your favorite method to boot from a USB flash drive?
Now you know three different ways to use a USB flash drive to boot your computer. Which of them is your favorite? Do you use the options built into Windows 10, or do you prefer to do it from BIOS/UEFI? Did you manage to boot your PC from a USB drive? If you did not, what went wrong? Comment below and let's discuss.
