Answer 1

I too faced the same problem. Just follow the below steps and you will get to fix the issue.

1. Go to the C:\Program Files\Oracle\VirtualBox\drivers\vboxdrv folder.

2. Right-click on VBoxDrv.inf and click on Install.

3. Run the Command Prompt as an administrator.

4. Enter the following command and hit Enter.

   sc start vboxdrv

5. Open Virtual Box and run the virtual machine again.

Okay - got it working.
Here's what I did.

Went to the C:\Program Files\Oracle\VirtualBox\drivers\vboxdrv directory, right clicked on VBoxDrv.inf and selected Install. I then went back to my console and typed 'sc start vboxdrv' and got this:
SERVICE_NAME: vboxdrv
        TYPE               : 1  KERNEL_DRIVER
        STATE              : 4  RUNNING
                                (STOPPABLE, NOT_PAUSABLE, IGNORES_SHUTDOWN)
        WIN32_EXIT_CODE    : 0  (0x0)
        SERVICE_EXIT_CODE  : 0  (0x0)
        CHECKPOINT         : 0x0
        WAIT_HINT          : 0x0
        PID                : 0
        FLAGS              :

Went back to VirtualBox and was able to start the Ubuntu virtual machine.
