Unable to start Guest OS on Virtual Machine as Kernel driver not installed

Question

I am using Virtual Box on Ubuntu Host machine and Windows 7 as Guest OS. I was able to run Windows before many times but recently after installing updates on my Ubuntu Box, it is showing error. Below is the screenshot of the error-

Below is the detail of the error-

The virtual machine 'Windows' has terminated unexpectedly during startup with exit code 1 (0x1).


Result Code: 
NS_ERROR_FAILURE (0x80004005)
Component: 
MachineWrap
Interface: 
IMachine {f30138d4-e5ea-4b3a-8858-a059de4c93fd}

As per the suggestion, I tried running sudo /sbin/rcvboxdrv setup on terminal, but it failed with following message-

ravi@Dell:~$ sudo /sbin/rcvboxdrv setup
Stopping VirtualBox kernel modules ...done.

Removing old VirtualBox kernel module ...done.
Recompiling VirtualBox kernel modules ...done.
Starting VirtualBox kernel modules ...failed!
  (modprobe vboxdrv failed. Please use 'dmesg' to find out why)

The dmesg command is showing following information-

The virtual box log /var/log/vbox-install.log is displaying Kernel configuration is invalid. Please see the below error in log file-

test -e include/generated/autoconf.h -a -e include/config/auto.conf || (        \
    echo >&2;                           \
    echo >&2 "  ERROR: Kernel configuration is invalid.";       \
    echo >&2 "         include/generated/autoconf.h or include/config/auto.conf are missing.";\
    echo >&2 "         Run 'make oldconfig && make prepare' on kernel src to fix it.";  \

I tried sudo make oldconfig && make prepare but it also failed. Below is the error message-

If you recently installed a new kernel version, try the earlier one. Kernel vmlinuz-4.2.0-42-generic doesnt work for me, but vmlinuz-4.2.0-41-generic works. Apparently, there is no vboxdrv version for vmlinuz-4.2.0-42-generic . I'm using VirtualBox 5.1.
