Cannot boot Windows guest in VirtualBox without kernel module error : <p>I'm running Vagrant (1.8.1) + VirtualBox (5.0.12) on Windows 7 and trying to boot up a Windows 7 image (modernIE/w7-ie8). However, I get this error:</p>

<pre><code>---------------------------
VirtualBox - Error In supR3HardenedWinReSpawn
---------------------------
&lt;html&gt;&lt;b&gt;NtCreateFile(\Device\VBoxDrvStub) failed: 0xc0000034 STATUS_OBJECT_NAME_NOT_FOUND (0 retries) (rc=-101)&lt;/b&gt;&lt;br/&gt;&lt;br/&gt;Make sure the kernel module has been loaded successfully.&lt;br&gt;&lt;br&gt;&lt;!--EOM--&gt;where: supR3HardenedWinReSpawn
what:  3
VERR_OPEN_FAILED (-101) - File/Device open failed.

Driver is probably stuck stopping/starting. Try 'sc.exe query vboxdrv' to get more information about its state. Rebooting may actually help.&lt;/html&gt;
---------------------------
OK

<p>I ran the query command, but the service "is not found".</p>

<pre><code>&gt; sc.exe query vboxdrv
[SC] EnumQueryServicesStatus:OpenService FAILED 1060:

The specified service does not exist as an installed service.
</code></pre>

<p>I tried rebooting, too. Nothing.</p>
