当您启动计算机时，它只显示黑屏或空白屏幕并带有闪烁的光标（可能看起来像下划线），这意味着BIOS 或 UEFI正在尝试从硬盘驱动器以外的源启动。只有在找到可以引导的确切路径时，引导的下一步才会开始。在这篇文章中，我们将分享您可以采取哪些措施来解决这种情况。

电脑^(Computer)开机黑屏或黑屏

如果您的Windows计算机重新启动并引导至黑屏/空白屏幕且光标闪烁，通常是因为引导设备冲突。有一些简单的方法可以解决这个问题，只有当源损坏或无法访问时它才会失败。

1. 移除不必要的外部设备
2. 更改引导源的顺序
3. 更换硬盘^{(Change Hard Drive)}或重新安装 Windows^{(Reinstall Windows)}
4. 运行黑屏疑难解答

某些解决步骤需要了解计算机 BIOS并可以更改一些设置的人。如果您不知道，最好寻求帮助来解决它。

1]删除^(Remove)不必要的外部设备

如果您有一个用于安装Windows或使用可启动设备执行重置但后来格式化的USB设备，那么这可能是一个问题。^(USB)BIOS仍在调查中。

另一组情况是您尝试从错误的USB驱动器启动。它可能是一个外观相似的USB，但无法启动。第二个可能是可引导 USB^{(bootable USB)}的创建不成功。

对于这些情况，您需要做的就是移除额外的USB或光驱^(Optical)连接。

2]更改引导源的顺序

启动进入 BIOS，将启动源的顺序^{(order of boot source)}从 CD-ROM/Drive 更改为HDD。更改过程因计算机而异，但这里是基本步骤。

• Press F2/F10/Del键启动进入BIOS 设置^{(BIOS Settings)}
• 切换到书籍部分
• 找到定义引导顺序的部分
• 选择 HDD^{(Select HDD)}，然后使用Page up 或Page down 更改顺序。

3]更换硬盘

如果没有其他工作，那么它可能是硬盘驱动器^{(Hard Drive)}。BIOS无法找到可以引导的信息，因此它一直显示黑屏/空白屏幕并带有闪烁的光标。要仔细检查硬盘^(HDD)状况，您可以连接到另一台计算机并尝试从它启动。如果它仍然不起作用，那么您将不得不重新安装 Windows或使用恢复方法修复引导记录。

在修复过程中，如果恢复无法找到硬盘，那么是时候购买一个新的了。我们建议您切换到 SSD，这将使整体体验更快。

4]运行黑屏疑难解答

您还可以使用Microsoft的在线^(Microsoft)黑屏疑难解答，看看是否有帮助。

我们希望这些方法能够解决每次启动计算机时出现空白或闪烁光标的问题。

Computer boots to black or blank screen with blinking cursor

When you boot a computer, and all it shows is a black or blank screen with а blinking cursor (it may look like an underscore), then it means the BIOS or UEFI is attempting to boot from a sоurce other than the hard drive. The next step of the boot will only begin when it finds the exact path from where іt can boot. In this post, we will ѕhare what you can do to resolve this situation.

Computer boots to black or blank screen

If your Windows computer restarts & boots to black/blank screen with a blinking cursor, it is usually because of conflicting boot devices. There are some easy ways to fix this problem, and the only time it will fail when the source is corrupt or not accessible.

1. Remove unnecessary external devices
2. Change the order of boot source
3. Change Hard Drive or Reinstall Windows
4. Run Black Screen Troubleshooter

Some of the resolution steps will need someone who understands computer BIOS and can change a few settings. If you do not know, it is best to seek help to fix it.

1] Remove unnecessary external devices

If you have a USB device that you had used to install Windows or perform a reset using a bootable device but had later formatted, then this could be a problem. The BIOS is still looking into it.

Another set of situations is where you are trying to boot from a wrong USB drive. It could be a similar-looking USB, juts not bootable. The second probability is the creation of bootable USB was not successful.

All you need to do for these scenarios is to remove the additional USB or Optical drive connection.

2] Change the order of boot source

Boot into BIOS, and change the order of boot source from CD-ROM/Drive to HDD. The process of changing will differ from computer to computer, but here are the basic steps.

• Press F2/F10/Del key to boot into BIOS Settings
• Switch to Book section
• Locate the section which defines the order of the boot
• Select HDD, and use Page up or Page down to change the order.

3] Change Hard Drive

If nothing else works, then its probably the Hard Drive. The BIOS is not able to find information from where it can boot, and hence it keeps displaying the black/blank screen with a blinking cursor. To double-check the HDD condition, you can connect to another computer and try to boot from it. If it still doesn’t work, then you will have to reinstall Windows or fix the boot record using the recovery method.

During the fix, if the recovery is not able to find the hard drive, then it’s time to buy a new one. We recommend you switch to SSD, which will make the overall experience a lot faster.

4]  Run Black Screen Troubleshooter

You can also use the online Black Screen Troubleshooter from Microsoft and see if that helps.

We hope the methods were able to resolve the problem of blank or blinking cursor every time you boot your computer.
