What to do if VirtualBox displays Black screen and not Booting guest OS in Windows 10
If VirtualBox suddenly displays a black screen without any text or mouse cursor when you are trying to boot a guest operating system, then read on as this post will guide you in fixing such issue. This black screen occurs when Windows 10 failed to provide a specific setting that VirtualBox requires. Consequently, you will not be able to install or use any guest operating system in VirtualBox even if your PC has a virtualization support, the best thing you can do now is to fix this black screen issue.
Not sure about the black screen but if it doesn't automatically go to fullscreen and you installed Guest Additions you might need to check your BIOS and make sure virtualization technology (vt-d) is enabled. Your right ctrl key will toggle control between your host and guest for mouse and keyboard. Hello, I've installed Oracle VM VirtualBox and downloaded Cloudera quickstart 5.8.0-0. I'm still not able to lauch the VM desktop. I'm stuck at the blackscreen after the loading bar is down (see image below) I've enable virtualization in BIOS, and tried different set up (Windows and Red Hat) but.
There are two ways you can fix this black screen in VirtualBox, you can either try to disable Hyber-V or disable 3D Acceleration. For more details, refer to each one of the given options below.
Hyper-V is a built-in virtualization tool available in Windows that helps users in creating a virtual machine as well as install a guest operating system without using any third party tool like VMware, VirtualBox, and many more. However, the problem with this virtualization tool is that some systems cannot run it and VirtualBox simultaneously which is most likely why the screen abruptly turns into black. Thus, you have to disable Hyper-V to resolve the problem. How? Refer to these steps:
- In the Start Search, type “Turn Windows features on or off” and then click on it from the results.
- Once you’ve opened the Windows Features window, remove the checkmark from the Hyper-V box.
- Click the OK button and then restart your computer.
- Now try to use VirtualBox again and see if the problem is fixed.
The guest operating system will use the host computer’s GPU to render 3D graphics if you enable the 3D Acceleration for the virtual machine. To simply put it, it will enhance the graphics of the virtual machine and will let you use 3D graphics. Although it may seem nice, it can actually cause the black screen to appear as well so you might have to disable it to isolate the problem. In fact, a lot of operating systems have failed to use the 3D Acceleration for the guest operating system because of this black screen issue. To disable it, follow these steps:
- Open VirtualBox in your computer and select the virtual machine.
- Next, click on the Settings button and go to the Display section.
- After that, look for a checkbox named “Enable 3D Acceleration” located on your right hand side and then uncheck it.
- Save the changes you’ve made and reboot your PC and see if you can now run the virtual machine without any problem.
Apart from the black screen problem with the virtual machine, if your Windows 10 computer experiences other issues as well, there is also another option that might help. Often referred to as a

I have VirtualBox with two working virtual machines(VM): Windows and Linux Mint. I created new VM for the latest Linux Mint 19.3 which was installed successfully but after reboot the screen was black. No matter of changing or resizing the window. I decided to install the older working version and see if the problem is solved. But again - successful install followed by black screen after boot of the machine. The old machine were working fine.
So after short investigation of the problem I found several possible problems and solution which I decided to wrap up in article. Some of them are related to dual monitor setup, others to incorrect graphic settings. Please find them below.
It's good idea to ensure that guest additions are installed for this Virtual Machine. If not you can follow how to install them in this article:
Ubuntu Linux add VirtualBox Guest Additions
Ubuntu Linux add VirtualBox Guest Additions
Step #1: Check logs of VirtualBox for errors
The first thing you need to start when you have problems with your programs and VirtualBox in this case are the logs. The logs will help you to find what is causing the problem no matter of the VMs - Ubuntu, Linux Mint or Windows.
in order to see the logs:
- Start VirtualBox
- Start the VM which has blank screen
- Open Logs
- right click on the machine
- Show logs - CTRL + L
For example:
The logs above are taken when the guest VM Linux Mint has low Video Memory and full screen is activated for resolution: 2560x1440. In this case I can see only the last screen shown from the VM before the full screen. If I escape the full screen the VM starts working again.
or messages like:
which indicates possible problem with BIOS. It highly depends on the VirtualBox version and the hardware - so I recommend for you to test next steps in order to solve blank screen.
Another interesting messages are:
- 00:00:01.507808 GUI: 2D video acceleration is disabled
- 00:00:42.162769 GUI: UIMultiScreenLayout::update: GUI/AutomountGuestScreens is disabled
Step #2: VirtualBox Guest Low Video Memory
The only change I did for VirtualBox was to change default folder where the machines are stored(between the creation of the working and not working machines). This can be done by:
- File
- Preferences
- General
- Default Machine Folder
After reset to the initial folder the problem was still present. So after quick research I found that virtual memory will cause display issues.
If you need more memory for your Virtual Machine you better go with VMware Player because it has limit of 2 GB of Graphics memory while VirtualBox is 128 MB. If you plan to play games especially you can check these links:
Increase VM Graphics Memory
- Stop the VM
- Select the problematic VM
- Settings(Right Click)
- Tab Display
- Increase the Video Memory to 128 MB (or something higher than initial 16 MB in my case)
- Start VM and the problem should be resolved
Step #3: VirtualBox Change the Graphics Controller
This option works only for VirtualBox 6 (the option is not present in VirtualBox 5 and before). You can check the version of the VirtualBox by:
- start it
- Help
- About VirtualBox - then you will see something like: 5.2.34 or 6.0.14
Many complaints are reported for problems related to Graphic Controller which can be changed by:
- Stop the VM
- Select the problematic VM
- Settings(Right Click)
- Tab Display
- Graphics Controller
- select VBoxSVGA
So if you are running VirtualBox 6 and you have VBoxSVGA as display controller than you can try by increasing the video memory(step 1).
Step #4: Disable Hyper-V
Since VirtualBox 6 there are other changes which might cause blank screen and new notifications. For example if Hyper-V is enabled but not able to use the load of the Virtual Machine will be slow. Icon for green turtle will be shown in the notification area of VirtualBox as shown below.
In this case you need to disable Hyper-V:
- Stop the VM
- Select the problematic VM
- Settings(Right Click or from the menu)
- Tab System
- Acceleration
- Hardware Virtualization
- Change it to default in case it was changed:
Step #5: Multiple monitors, full screen, drivers and resolution
Another possible reasons for blank images of your machine might be:
Multi-monitor Setup
In case that you have multiple monitors but settings in the VirtualBox show warning or bad configuration. Open and verify that information in display tab are correct about: Monitor Count. You can also test with single monitor setup and see if the problem is still present.
Full Screen
Virtual machine which works fine in window can stop responding after going into Full Screen or Seamless mode. In this case you need to escape the VM from Full screen mode. This can be done by clicking the menu bar - button maximize or minimize as shown on the picture below:
Note: Sometimes the menu is hidden and you it should be shown by mouse hovering on it. In most cases is hidden in the bottom or top middle.
Virtualbox Full Screen Black
Drivers
As always is good idea to have latest version of Video Drivers for you Linux Mint installation. The latest driver available should be:
nvidia-driver-435
. If you have problems installing latest graphic drivers for Ubuntu or Linux Mint please check this article: Install Latest NVidia Drivers - Ubuntu and Linux MintResolution
In case that your harder is older or the machine has low performance profile - you can try to decrease the resolution for the guest machine.
Bonus #1: Check VirtualBox for warnings
Sometimes VirtualBox will show warnings in case of bad settings. You can check tabs: Display and System. Below you can find example of warning showing:
Invalid settings detected
:The warnings can help if there is problem with:
Google Docs
- Monitor Count
- Video Memory
- Invalid Storage
- Virtualization

But some errors are not so obvious - in this case best is to check the logs (as described in step 1).
