How To Partition A Hard Drive

Disk partitioning is the act of dividing a hard disk drive (HDD) into multiple logical storage units referred to as partitions, to treat one physical disk drive as if it were multiple disks, so that different file systems can be used on each partition.
People don’t often choose to partition their hard disks, but it has many benefits. Mainly, by partitioning your disk, you can separate your operating system from your data and thus reduce the chances of your data becoming corrupted.
Steps

1. Open the Computer Management tool. Open the Start menu. Type “Computer Management” in the search bar of the Start menu and press enter. 
   
2.  Select the Disk Management tool. Click on Disk Management on the left side of the window and you should see all of the disks and their partitions on your computer. 
   
3.  Make some space for the new partition. Right-click on the partition you wish to re-size and select the Shrink Volume option. 
   
4.  Shrink the drive. Enter the size you wish to shrink your drive to in megabytes. Then click on the Shrink button (102,400MB for a 100GB partition, etc.).
   
5. Create a new volume. You should now see a new unallocated partition in your Disk Management window. Right-click on the Unallocated partition and select the New Simple Volume option.
