In this small article, I shall show how to partition your Hard Disk while your computer is fully functional (without formatting stuffs and doing partition at the time of installation).


Generally when we buy a new laptop of computer, the vendor gives the whole hard disk as a single partition. In order to organize our stuffs well we feel the need of a separate partitions. In this article, I am going to show the steps of doing partition of the hard drive while you are working on your computer. You do not need to format the disk and do the partitioning at the installing the operating system.


Generally it is not suggested to partition the hard drive as I have heard that it slows down the system performance. Also you must ensure that you have backup of all your important data and softwares including Operating System so that you can install them again in case something goes wrong.
