Installing Ubuntu 14.04.2 LTS for dual boot

1) Install minimal Ubuntu.
   In my case, Ubuntu 14.04.2 LTS

 a) Shrink partition size of C (from Windows) to make free space for installing Ubuntu
    In my case, partition #5 is the free space for installing Ubuntu.

 b) Insert installation CD or USB

 b) Make the partition #5 as EXT4.
     Mount point is /
     make available space for swap area (e.g. 30GB)

 c) Make swap area.
    It should be more than memory size. (e.g. 30GB.)

 d) user name: stack (for convenience when installing DevStack)
