Ok, This should not be a problem.

First try with wubi which comes with Ubuntu 1404 LTS CD. Inside there wubi icon can be found. Once you double click it, it will starts the installation as a normal windows program. But what this does is that it installs the Ubuntu on the system as a dual boot instead as a program inside the windows. Thats all..

When system rebooting it will give you list of OS to select.


In the Ubuntu terminal, execute the command line below:

sudo update-grub

Then reboot the system, then you could see the boot menu options including both windows7 and ubuntu.
