- Open the drive and install the VBoxWindowsAdditions-amd64.exe if your VM is 64 bit.
If you are running a 32-bit virtual machine, you must install VBoxWindowsAdditions-x86.exe - The installation of this driver is pretty straight forward. Change the destination folder, if you want this to be installed at some different location, else simply click on Next.
- Click on Next, Next on each screen until you see below pop up. Make sure to click on Install, to have the driver installed correctly.
- Once the installation is complete, select the 'Reboot now' radio button.
Once your virtual machine is restarted, the VM opens in full screen mode and the display options disabled earlier are now enabled.
