Solution of VirtualBox error “Kernel driver not installed (rc=-1908)”

I noticed somehow an error in VirtualBox working on Linux Ubuntu Desktop 16.04:

Kernel driver not installed (rc=-1908)
The VirtualBox Linux kernel driver (vboxdrv) is either not loaded or there is a permission problem with /dev/vboxdrv. Please install virtualbox-dkms package and load the kernel module by executing
‘modprobe vboxdrv’
as root. If it is available in your distribution, you should install the DKMS package first. This package keeps track of Linux kernel changes and recompiles the vboxdrv kernel module if necessary.
where: suplibOsInit what: 3 VERR_VM_DRIVER_NOT_INSTALLED (-1908) – The support driver is not installed. On linux, open returned ENOENT.

To solve the problem it was necessary to disable the secure boot in the BIOS, in my case “Windows UEFI” was selected, changed to “Other OS”.
Then after startup, the system executed the command from the root user:

modprobe vboxdrv

In Ubuntu, you can switch to root as follows:

sudo -i

Done, the error is solved.
