Windows 10 pro x64, windows 7 ultimate x64 sp1, windows 8.1 pro x64 new 20 dec 2016 #2 virtualbox uses an emulated graphics card not your actual hardware so there is no need nor are you able to install the host machine driver.. Gpu: nvidia geforce gtx 520 1gb i've setup a virtual machine using virtualbox with windows 7 as guest. i want to use my (host's) graphics card in it but the virtual machine is only showing 128 mb of video memory.. For testing purposes i always have a virtualbox machine with the latest windows 10 build. i installed windows 10 build 10041 and faced an issue that the virtualbox video driver did not work in it..
Anyone know how to get the drivers and the guest additions cd image to work on windows 10 tech preview? i really like it i just think that it needs guest additions. whenever i try to install, it comes up with a dialogue saying: "the virtualbox guest additions cannot be installed on this version of windows".. I'm also experiencing the same issue running windows 10 enterprise 64-bit on a vm with 4 processors, 8gb memory, 128 mb video memory, 2 screens, 2d video acceleration, on a host running windows 7 enterprise 64-bit on a core i7 vpro with 16gb memory.. Then updated the settings for virtualbox to windows 10 (32-bit) version and updated the system processor by checking extended features: enable pae/nx. finally proceed as explained in this answer and download the windows media creation tool to force the update..
