Nov 4, 2017 - High Sierra comes with a new security feature: Secure Kernel Extension Loading, which blocks kernel extension loading. The implementation. Install Mac OS X El Capitan on VirtualBox. First, what you are going to do is download the VirtualBox for Windows from its website. Once you have downloaded the VirtualBox, then install it on your computer. If you run VMware or Hyper-V so, you should not use them at the same time. Because you can not run two different Virtualization software on one PC.

• When I installed VirtualBox it said that the installation 'failed' but I still got VirtualBox.app in my applications folder. • When I try to boot windows 7 VM, it says 'Kernel drivers not installed (rc = -1908). • Online solutions are saying I should 'restart the host'. I checked my StartupItems folder and it's empty.

So I guess the installer failed to install kernel extensions. So there's this thing called SIP which prevents installing kernel extensions. Should I disable it for now? What do I do?

I need a Windows virtual machine in 8 hours.

Hey, Host computer is Windows 7, Virtualbox is also full installation of Windows 7. The Virtual Win 7 is running good except that there are no GPU drivers installed on it. I tried downloading drivers from AMD's website, but as the installation starts, I get an error and the installation stops.

I don't really know what the Guest Additions really is but I downloaded VBoxGuestAdditions_2.2.0.iso and installed it on the Virtual Win 7 but I still don't seem to have any GPU drivers and I can't install the drivers from AMD manually. Posts: 7 Joined: 12. May 2015, 12:04.

You don't need AMD drivers in your guest because your guest Windows 7 does not see the AMD video card your host has. (I assume that your host has an AMD GPU, since you didn't actually say your host had that kind of card, just that you were downloading AMD drivers for the guest.) The guest's hardware is all virtual, except for the CPU. So the video card is a simulated Virtualbox video card, and the special drivers for this 'card' come from the Guest Additions. In almost all situations, the Guest Additions to be installed is the version that comes with Virtualbox.

So unless you're running Virtualbox version 2.2.0, you should uninstall those rrrrreeeeaaaallllyyyy old Guest Additions, and install the ones with the Virtualbox version you're running now: See the Devices menu on the guest's window, choose to load the Guest Additions at the bottom of the menu. The Guest Additions matching the version of Virtualbox will load itself into the guest's virtual CD drive, which you would open and run if Autorun doesn't start the install for you. I don't really know what the Guest Additions really is but I downloaded VBoxGuestAdditions_2.2.0.iso and installed it on the Virtual Win 7 but I still don't seem to have any GPU drivers and I can't install the drivers from AMD manually. No idea where you found the VBoxGuestAdditions_2.2.0.iso but the current version is VBoxGuestAdditions_4.3.26.iso. There is however no need to download the guest additions separately.

They come with the VirtualBox package and can be installed from the 'Devices' menu. The user manual is a wonderful thing. Edit: scott beat me to it.

Why did you do that instead using the Guest Additions supplied with every VirtualBox release?

I'd just like to know where you got the idea that the Guest Additions are something that should be downloaded separately. They can be, but in 99.99% of cases it is unnecessary. Microsoft outlook free download for mac.

Just trying to figure out how to make it clearer to users where to find the Guest Additions. Oracle Corporation Posts: 2932 Joined: 19.
