Today to troubleshoot battery not charging issue due to over heating on my Dell laptop running on Windows 8, I have decided to load the Ubuntu OS onto my system. Ubuntu is known as one of the best free Linux operating system available today. I have downloaded the Ubuntu and installed in a new partition on my hard disk. It got installed properly without any issues. I was able to boot and work on Ubuntu OS. But when I restarted my PC, Windows 8 is not loading! However I was able to boot on Ubuntu. I am new to Ubuntu eco system, so I did research on forums to fixing this problem. My Windows 8 partition is intact and the only problem is, GRUB is not working as expected. After a some 8 to 10 minutes of research on forums, I got a very simple and quick solution to it. So I am sharing the same solution to you which worked for me.

Steps to Fix Ubuntu Booting Issue after Installing Windows 8
This one I have not tried. However, I am just quoting the solution provided in the forum. Here I assume that you have installed Ubuntu first and then installed Windows 8. Now you cannot boot on to Ubuntu. In this case, first boot your computer ona Ubuntu live-CD or live-USB.Then follow the same procedure mentioned above. It updates GRUB and you will be able to access Ubuntu.
