Dual boot Windows and Centos 7

After I installed centos 7 in my system, I noticed that my windows 8 installation is not showing in the grub.

What to do when your computer running ubuntu freezes?

This is what you can do when your Ubuntu freezes There are different types of freezing, from a single program stops responding, to the entire system lock up. I will try to address them one by one.
