如果您尝试启动客户操作系统，但VirtualBox 显示黑屏^{(VirtualBox displays a black screen)}，没有任何文本或鼠标光标，您可以尝试以下几种解决方案。VirtualBox需要一个特定的设置。如果您的Windows系统无法提供该功能，VirtualBox可以显示此黑屏。因此，即使您的计算机支持虚拟化，您也无法在VirtualBox中安装或使用任何来宾操作系统。^(VirtualBox)

Windows 11/10 上的VirtualBox^(VirtualBox)黑屏

要解决VirtualBox中这个非常常见的问题，您需要遵循以下建议：

1. 禁用 Hyper-V
2. 禁用 3D 加速。

完成此操作后，VirtualBox将开始正常运行。

1]禁用Hyper-V

Hyper-V是Windows内置的虚拟化工具，可帮助用户创建虚拟机并安装客户操作系统，无需任何第三方工具，如VMware、VirtualBox等。问题是某些系统无法运行Hyper-V和VirtualBox同时地。因此，如果您的Hyper-V已启用，如果您想使用VirtualBox ，您需要禁用它。

要禁用或关闭Hyper-V，您可以按照以下步骤操作。

搜索打开或关闭 Windows 功能^{(Turn Windows features on or off)}。打开Windows 功能^{(Windows Features)}窗口后，从Hyper-V框中删除复选标记，然后单击确定^{(OK )}按钮。

完成该过程后，重新启动计算机并尝试使用VirtualBox。它应该运行没有任何问题。

2]禁用3D加速

如果为虚拟机启用 3D加速^{(Acceleration)}，来宾操作系统将使用主机的GPU来渲染 3D 图形。简而言之，它将改善虚拟机的图形并让您使用 3D 图形。但是，同样的事情也可能导致问题。许多系统未能为来宾操作系统使用 3D加速^{(Acceleration)}。

因此，您可以尝试禁用此选项。为此，在您的计算机上打开VirtualBox > 选择虚拟机 > 单击“设置”^{(Settings )}按钮并转到“显示”^{(Display )}部分。在您的右侧，您应该会找到一个名为Enable 3D Acceleration的复选框。

从复选框中删除标记并保存您的更改。

重新启动计算机并检查是否可以正常运行虚拟机。希望^(Hopefully)您可以毫无问题地使用来宾操作系统。

如何修复VirtualBox上的黑屏？

如果在Windows 11/10上启动来宾操作系统时在VirtualBox上出现黑屏，则需要做两件事。您必须打开Hyper-V并禁用 3D加速^{(Acceleration)}。可以使用Windows 功能^{(Windows Features)}面板在Windows 11/10计算机上禁用Hyper-V 。另一方面，您可以从 VirtualBox 的 显示 ^(Display )设置面板中禁用 3D加速。^{(Acceleration)}

All the best!

VirtualBox displays Black screen and not Booting guest OS

If you are trying to bоot a guest operаting ѕystem, but VirtualBox displays a black screen without any text or mouse cursor, here are a couple of solutions you can try. There is a specific setting that VirtualBox requires. If your Windows system fails to provide that, VirtualBox can show this black screen. As a result, you cannot install or use any guest OS in VirtualBox even when your computer has virtualization support.

VirtualBox black screen on Windows 11/10

To fix this very common issue in VirtualBox, you need to follow these suggestions:

1. Disable Hyper-V
2. Disable 3D Acceleration.

Once you have done this, VirtualBox will start functioning normally.

1] Disable Hyper-V

Hyper-V is an inbuilt virtualization tool available in Windows that helps users create a virtual machine and install a guest operating system without any third-party tool such as VMware, VirtualBox, etc. The problem is some systems cannot run Hyper-V and VirtualBox simultaneously. Therefore, if your Hyper-V is enabled, you need to disable it, if you want to use VirtualBox.

To disable or turn off Hyper-V, you can follow these steps.

Search for Turn Windows features on or off. After opening the Windows Features window, remove the checkmark from Hyper-V box and click the OK button.

After completing the process, restart your computer and try using the VirtualBox. It should run without any problem.

2] Disable 3D Acceleration

If you enable 3D Acceleration for the virtual machine, the guest OS will use the host computer’s GPU to render 3D graphics. In simple words, it will improve the graphics of the virtual machine and lets you use 3D graphics. However, the same thing can cause an issue as well. Many systems have failed to use the 3D Acceleration for the guest OS.

So you can try disabling this option. For that, open VirtualBox on your computer > select the virtual machine > click the Settings button and go to the Display section. On your right-hand side, you should find a checkbox named Enable 3D Acceleration.

Remove the mark from the checkbox and save your change.

Restart your computer and check if you can run a virtual machine properly or not. Hopefully, you can use the guest OS without any problem.

How do I fix black screen on VirtualBox?

If you get a black screen on VirtualBox while booting a guest OS on Windows 11/10, you need to do two things. You must turn on Hyper-V and disable the 3D Acceleration. It is possible to disable Hyper-V on your Windows 11/10 computer using the Windows Features panel. On the other hand, you can disable 3D Acceleration from the Display settings panel in VirtualBox.

All the best!
