I managed to resolve the issue but not by uninstalling Hyper-V. I saw a couple of suggestions but I find this one suitable:
STEP 1:
Open the command prompt as an Administrator.
STEP 2:
Run the command with no argument:
bcdedit
After you run the above command, you will see that the property hypervisorlaunchtype is set Auto by default. See screenshot below:
STEP 3:
Disable Hyper-V by running the command:
bcdedit /set hypervisorlaunchtype off
STEP 4:
Restart your PC system to use VirtualBox.
To turn Hyper-V back on, run the command:
bcdedit /set hypervisorlaunchtype auto
You will need to reboot the system to use Hyper-V.
