VirtualBox displays Black screen

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 an 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 virtualization support, the best thing you can do now is to fix this black screen issue.

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.

Option 1 – Try to disable Hyper-V

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.

Option 2 – Try to disable 3D Acceleration

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 on 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.

Turn On or Off the Recommended Troubleshooting
For a while now, Microsoft has been working hard to add various built-in troubleshooters in Windows 10. In fact, there is a troubleshooter for almost every standard or common error in Windows 10. And now with the newly released Windows 10 v1903, Microsoft has added the Recommended Troubleshooting which allows Windows 10 to automatically fix a lot of critical issues on your computer, and in this post, you will be guided on how you can turn on or off the Recommended Troubleshooting in Windows 10. The Microsoft Diagnostic & Feedback data only provides two settings – Basic and Full. So if you want to turn off the Recommended Troubleshooting for some reason, the only way to do so is to stop it from collecting complete data from your PC. And to turn it on or off, you can choose to switch between them. To do that, navigate to Settings > Privacy > Diagnostics & feedback and from there, select Basic under the Diagnostic Data section. After that, go back to Settings and go to Update & security > Troubleshoot. Once you’re there, you should see a warning message saying, “Share Full Diagnostic data to get additional troubleshooting recommendations”. Based on the message, Microsoft will only offer the recommended troubleshooting based on the Full Diagnostic data which it collects from your computer. On the other hand, if you know how to navigate and use the Windows Registry, then you can enable or disable the Recommended Troubleshooting via Registry Editor but before you proceed, make sure that you create a System Restore point. Once that’s covered, follow these steps:
  • Tap the Win + R keys to open the Run dialog box and type “regedit” in the field and tap Enter to open the Registry Editor.
  • Next, navigate to this registry path: HKEY_LOCAL_MACHINESOFTWAREMicrosoft
  • From there, look for the key named “WindowsMigration”. If you can’t find it, just right-click on the left pane and create a new key and then name it “WindowsMigration”.
  • After that, create a DWORD “UserPreference” and double click on it to set its value to “0” if you want to turn it off or “1” if you want to turn it on.
  • Exit the Registry Editor and restart your computer to apply the changes made.
Note: The Recommended Troubleshooting functionality can look into the error logs sent back to the Microsoft team and use an algorithm to set up a solution for you and they’re nothing but Diagnostics and Feedback data that Windows collects and sends back to Microsoft. Moreover, the recommendations are only visible if you are connected to the internet, else it will show the same message.

What is Windows 10X and do you need it

What is Windows 10X

Windows 10X is a new version of Windows that has been built from the ground up for new PCs and will begin shipping on hardware in 2021. It's built on top of a new modern version of Windows called 'Windows Core OS' that guts legacy components and features in favor of contemporary user experiences and enhanced security. This means everything from the Windows Shell to the underlying OS has been rebuilt with modern technologies.

As a result, Windows 10X does not support legacy Win32 applications at launch. Windows 10X PCs in 2021 will be able to run Microsoft Edge, UWP, and web apps. Legacy Win32 application support will arrive at a later date, however. When it does, Win32 applications will run in a secure container by default, meaning those legacy applications cannot affect system performance and battery life when closed. Windows 10X is a much more secure and stable OS as a result of this, as there's no opportunity for legacy apps to cause bitrot.

Windows 10X features a new shell of the user interface that has been built with modern technologies. It's an adaptive user experience that can adjust depending on the "posture" of your device. For example, with a foldable PC, the user might want to use it in several different ways; as a laptop, or tablet, or in tent mode for movies. Because of this, the user interface must adapt to provide the best experience no matter which way your device is being used. This also means that legacy shell elements, such as the Control Panel, File Explorer, and error dialogs and icons are gone on Windows 10X. As Microsoft has rebuilt the entire shell, it doesn't include any of the legacy things that make Windows 10 so inconsistent when it comes to UI. The Windows Shell on Windows 10X should be much more consistent. At launch, Windows 10X will only be available on traditional clamshell PCs aimed primarily at the education and enterprise markets. The platform will eventually ship on the new devices from factors such as foldable PCs, but that won't be happening in 2021.

Start menu

Microsoft is redesigning the Start menu experience on Windows 10X with a focus on productivity. It features a system-wide search bar along the top that can also search the web and a grid of installed apps below that in place of live tiles. It also has a "recent activities" area that dynamically updates with things the user might want to jump straight into, such as recent Office documents and visited websites. The apps list can be customized, with the ability for users to rearrange which apps show up in the first few rows.

Taskbar

Windows 10X also has a new adaptive Taskbar that features a centered design. The Start and Task View buttons appear in the center, with running and pinned apps appearing between the two. When you open an app, the Start and Task View buttons gently spread apart, giving the Taskbar a much more fluid appearance. There are some new animations; the Start and Task View buttons have their own animations when clicked on, and there's a subtle bounce to app icons when you minimize running apps to the Taskbar. In addition to the new design, there are also up to three different Taskbar sizes: Small, medium, and large. Large is great for tablets, while medium and small mimic the usual sizes we already have today on Windows 10. On tablets, users can now swipe up anywhere on the Taskbar to access the Start menu, making it easier for touch users to access their apps list. You no longer have to hit the specific Start button to access your Start menu.

Action center

In addition to the new Start and Taskbar experiences, there's also a new Action Center to compliment them. This new Action Center puts more emphasis on quick actions, with the ability to jump into specific quick actions for further control without leaving the Action Center at all. It's also designed in such a way that mimics a control center, with notifications housed above it in a separate box. This new Action Center includes things like volume controls, power options, and battery percentage. There's also a new music control UI that appears in the Action Center when music is playing from a supported app.

State separation feature

Unlike Windows 10, Windows 10X features something called "state separation" which is how the OS lays itself out on a drive. Windows 10 today installs everything into a single partition, which means the user can access system files, as can apps and potential attackers. On Windows 10X, everything goes into its own read-only partition. So OS files are locked away, as are app files, as are drivers, and the registry. The only thing the user and applications can access is the user partition. This means that malware or viruses can't get in and affect the system because those programs are only able to operate in a single partition, and that assumes they're able to get outside of the app container system Microsoft has built. All apps on Windows 10X run in a container and need explicit permissions to access things that are outside that container. This is already how UWP apps work on Windows 10, and Microsoft will be extending that to Win32 apps on Windows 10X when support for Win32 apps arrives.

Launch date and info

Windows 10X will launch this spring first for commercial markets. Commercial markets include education and enterprise industries looking for sub-$600 PCs for students in the classroom or first-line workers. Windows 10X won't be launching on consumer PCs in 2021, meaning you won't find it on a flagship Dell or HP device. It's also only for clamshell PCs, with foldable, tablets, and other form factor support coming in 2022 and beyond. Windows 10X will launch without an in-box Mail and Calendar app. It's been removed from the first version of Windows 10X because the platform is aimed at commercial markets that will likely use Outlook Web or stream Outlook via Windows Virtual Desktop. Users can opt to reinstall the Mail and Calendar apps from the Microsoft Store if they wish. Windows 10X for mainstream markets won't happen until 2022 when Win32 app support among other features comes to the OS as part of the Windows 10 "Nickel" release scheduled for the first half of 2022. Because Windows 10X is a new operating system, it will not be released as an update for existing Windows 10 PCs. Users won't be able to install Windows 10X on a device that didn't come with Windows 10X, to begin with. There won't be any official ISO media and you won't be able to buy Windows 10X on its own to install on your existing device. It's for new PCs only.

Normally, it would take about several seconds for the system to boot and while on the startup process, error code 0xc000021a may take place to block the system to boot up. Users will get a blue screen of death (BOSD) when this error occurs. When upgrading to Windows 10, be careful; you might encounter other error messages such as error code 8007002c

Solution

Restoro box imageError Causes

There are several reasons why error code 0xc000021a occurs. It is important to have a full understanding of what caused the blue screen of death before attempting to fix the error by yourself. See below for a few common causes:

Computer malware has infiltrated your device.

• Important files such as Winlogon.exe and Csrss.exe are damaged. Winlogon.exe file is responsible for handling the login and logout processes while Csrss.exe is a vital part of Microsoft Client or Server ‘Runtime Server Subsystem’. Once one of these files is damaged or deleted, a stop error will occur.

• When there are mismatched system files installed or system upgrading process failed or still incomplete.

• Premature unloading of Wbemprox.dll

• Newly installed third-party software is not compatible with the operating system.

• There are corrupted, outdated, or incorrectly configured device drivers.

• There’s insufficient space in the system partition. Once the system partition is full, certain errors such as error code 0xc000021a will manifest.

• Windows registry is corrupted or damaged due to a software or system change. This means there are registry entries that are not cleared after uninstalling an application.

Further Information and Manual Repair

In fixing error code 0xc000021a, you might want to try and manually do so. Manual repair methods can give users effective and efficient solutions, addressing the root problems in relation to Windows error codes. Once the manual repair method is correctly implemented, users will be able to resolve issues immediately. However, there might be instances when a Windows professional is needed. In such cases, seek help from a certified Windows expert or you might want to consider using an automated tool whenever necessary.

Method One: Convert the Drive or Partition from NTFS to GPT

In order to fix Error code 0xc000021a in Windows 10, you might need to convert the partition or drive from NTFS to GPT. See below for the procedure: 1. Shut down your device then put in the Windows installation USB key or DVD. 2. Boot your device to the USB key or DVD in UEFI mode. 3. Inside the Windows Setup, open a Command Prompt window by pressing Shift + F10. 4. Type diskpart in the Command Prompt window to open the diskpart tool. 5. Type list disk to identify which drive to reformat. 6. Select which drive to reformat by typing select disk in the command prompt. Afterward, type clean then hit Enter. Once done, type convert gpt to be able to convert the drive from NTFS to GPT. Finally, type exit and press Enter. You can now close the Command Prompt window. 7. Once the partition or drive is converted from NTFS to GPT, the user can now continue the Windows Setup installation. NOTE: Select Custom in choosing which installation type to use. The drive will then appear as a single area of unallocated space. Choose that unallocated space then select Next. At this point, Windows will now begin the installation.

Method Two: Fix System File Errors

There are times when system files get corrupted or damaged which will result in system failure. If this is the case, you can use a Windows free tool to repair corrupted or damaged system files. 1. Right-click on the Start button then selects Command Prompt (Admin) from the list to open a Command Prompt window. 2. Once the Command Prompt appears, type sfc /scannow then hit Enter. Wait until the process completes. If the process is completed and it doesn’t report any error or issues that remain unsolved, you might want to employ the next method.

Method Three: Reset Windows 10

Resetting Windows will delete all software and user accounts installed in the operating system and will reinstall a fresh Windows. 1. Boot your device using a Windows installation USB key or DVD. Select Repair your computer to locate the Troubleshoot option. Afterward, choose Reset this PC.

You just have to boot the device then navigate to Settings in the Start button. Choose Update & Recovery then select Recovery found on the left pane. Choose Reset this PC option then select Go back to an earlier build and Advanced startup. Select Get Started button found in the Reset this PC tab. 2. Depending on your device’s condition, you can either select Keep my files or Remove everything. Both options will remove all applications installed in the device and will revert to default settings. 3. Choose either Just remove my files or Remove files and clean the drive depending on the situation. If you choose the Remove files and clean the drive option, the procedure will take longer as it will erase all the files permanently. In this case, deleted files cannot be recovered. However, if you don’t want to remove files permanently, select Just remove my files. 4. Once you’ve decided how to reset your system, click on Next once the Warning screen appears. Afterward, choose Reset once prompted. When the process completed, click on Continue.

Fixing TV screen resolution on PC
When you connect your TV via HDMI cable Windows will recognize it as another monitor and will control the display settings for your HDMI connection. In most cases using it as the extended desktop will work fine, issues will arise when you play video on it. Video playing applications can override Windows settings which can lead to strange results on the screen. Here in this guide, we will tackle with reasons and solutions to this particular issue. Solutions provided are not meant to be followed in the way they are presented but as a silent rule, they go from most common one to most rare so it is advisable to try them in the order presented.

FIXING RESOLUTION ISSUES

The first thing when experiencing resolution issues on your TV connected to a PC is to check TV settings. There is very likely a chance that you will need to manually adjust picture settings on the TV itself using TV controls. On older models of TV, there is an overscan option which can lead to different resolutions and screen sizes. Overscan is a technology that was used in order to help content creators to deliver consistent pictures on different screen sizes and aspect ratios but how technology has advanced and everything including aspect ratio was standardized overscan itself has become a relic of the past. If you are unable to access or see edges of your desktop on the TV screen it is very likely that overscan is the issue. In order to fix this be sure to select HDTV's aspect ratio to fit the screen setting in the picture setting. Sadly finding this option on your TV will be different from manufacturer to manufacturer and even from model to model of the same manufacturer so we can not cover all models but in most cases option is located under picture settings or advanced options. Sometimes you will face even different overscan settings instead of classic ft to screen options, in this case, experiment with the setting until you find one which will work. If you have it, find settings in the user manual of your TV. Luckily you have managed to find the proper option on your TV set and have chosen the right aspect ratio for display. If everything works ok there is no need for the next step but if you experience a different resolution than desired on your TV follow this next guide on how to change the resolution of the TV on your PC.
  1. Press the ⊞ Windows and type Change Display Settings. Click on the top result.
  2. Once the Display Settings App opens, you’ll see two screens (or more if you’ve got multiple HDMI outputs connected). Make sure you select the right display for the HDMI TV before making any changes. You can do this by clicking on Identify.
  3. You’ll see the number from the screenshot above displayed on the monitors for a brief period. Depending on which screen is set to your primary display, make sure you change the settings for the HDMI monitor.
  4. Select the HDMI monitor from the available displays.
  5. Scroll down until you see the current resolution settings for your HDMI monitor.
  6. You can change the resolution settings and test different values that match your HDMI TV’s configuration.
  7. Once you change the setting, Windows will apply the new resolution for a limited time and revert if you don’t accept the new setting.
  8. Once you’ve found the best resolution for your TV, select Keep Changes to keep the new resolution.
You are all set now, make sure that you have the latest drivers on your system and enjoy using your TV as a second monitor.
