I have a Dell Laptop with dualboot Windows 10 and Ubuntu Mate (Linux).
I have installed VirtualBox several times, but keeps getting an error.
I havve tried to disble UEFI, but that dident work.
I have tried several times to run different kind of fixes that I have found on the net, but with no result.
In the Ubuntu Mate forum, I got som feedback, and found a solution by running this commands;
sudo dpkg-reconfigure virtualbox-dkms
sudo dpkg-reconfigure virtualbox
And then;
sudo rmmod vboxnetadp vboxnetflt vboxpci vboxdrv
sudo /sbin/rcvboxdrv setup
And now it is working.
Remember to disable the UEFI boot.
