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.

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.

• Step four: Restart PC

Once the issue has been resolved, it is time to verify if the error code is fixed. Open Windows Update then select the option which enables you to access the latest upgrades to your machine. Wait to see if the error code reoccurs or if you can now access the upgrade to your operating system. If the error code reoccurs, move to the next manual repair method.

Method Three: Disable Firewall Settings

Another issue that may be causing an error code to occur is your firewall. To verify if your firewall is preventing you from accessing the upgrade, disable your firewall. If you are using third-party security software, simply open the security app and check its firewall settings. Select disable or turn off the firewall.

Restart your computer, then open Windows Update to reattempt to upgrade your device. If this proves successful, you will be able to access the upgrade. Error code 0x80072EE2 in Windows 10 will no longer be present.

If you suddenly encounter an error message saying, “ File Record Segment is Unreadable ” on a blue screen while booting your PC, it means that your hard drive is in an error state. This particular blue screen of death error might have a lot of bad sectors or might have reached its end. The workarounds you can try to resolve the issue is by locating the bad sectors or checking your hard drive for any discrepancies in the mapping and fix them. Follow the detailed instructions laid out below for these workarounds.

Option 1 – Try to check for any bad sectors and wrong configurations in your hard drive

The first thing you have to check is the boot files on your PC. As you know, your PC boots from these files and if there is anything wrong with any one of them or if one of them ends up getting corrupted, you will most likely see the blue screen of death error or a prompt with an error message saying, “File record segment is unreadable”. According to some users who reported this issue, new hard drives aren’t exempted from this error. That’s why it is recommended that you carry out this solution no matter what kind of scenario you are in. You will have to launch the Command Prompt in recovery mode and see if you can fix the problem by executing the check disk commands.

• Upon booting, restart your PC and tap F11 to go to the recovery environment then select Troubleshoot.
• Next, click Advanced from the given options and select Command Prompt.
• After opening Command Prompt, execute the commands listed below, and don’t forget to hit Enter right after you type in each one of them and if you have installed Windows to some different directory, you must replace “C” with the name of the drive you’ve installed Windows with.
• chkdsk C: /r /x
• chkdsk C: /f

Note: The Chkdsk function might take a while before it finishes its operations so you need to be patient and wait until the entire process is completed. And depending on the situation, it might even take a day at most so patience is really the key here.

Option 2 – Try connecting the hard drive to a different computer

If option 1 didn’t work for you and you’re still seeing the error, you can try connecting the hard drive to a different computer and then copy the data first. Make it a priority to salvage the data just in case the hard drive won’t make it in the future. After replicating your hard drive, you can then try running the chkdsk commands that are listed in option 1 above in the new computer you’re connecting your hard drive to and make sure that you key in the correct drive letter that’s assigned to the hard drive you’re using. After executing the chkdsk commands, plug your hard drive back into the previous computer and then check if you can now boot it without any issues.

Option 4 – Replace the faulty hard drive

If none of the options provided above really worked out then maybe it’s time to consider getting a replacement for your hard drive. In about 50% of the cases about this error, some unfortunate users were left with no choice but to replace the hard drive since the problem is with the hard drive itself. Hard drives have a complex running mechanism which includes a head and the disk that rotates accordingly so you can check if the cables connected to the hard drive are connected properly and if it is in a correct position or not. In addition, you also have to make sure that the SATA adapters where the hard drive is connected are working properly. If the drive is showing problems in the I/O operation, there is little chance for you to use it as a normal hard drive. If the hard drive is in warranty, get it checked and replace it. If not, you might consider taking it to the service center for the specialists to take a look into it.
