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.
