Create a new partition on a hard disk drive

One may want to create partitions on a hard drive for different reasons including ability to install multiple operating systems, separate personal files from operating system files, and to hide a particular partition from access. 

To do this, follow the steps below: 
1. Open control panel (start, control panel) 


2. Double click administrative tools

3. Open computer management 


4. Click on disk management on the left portion of the window that appears 

5. Right click on the unallocated space and click on create partition. 


6. Select the size of the partition 

7. Format the partition by right clicking on it and clicking format 

8. Restart your PC

 PS: this method works for disk space that are already unallocated. 


If there is already data on the disk, third party software can be used. a Google search will lead you to one. 

I recommend the use of easeus partition manager (because i have used it before and it worked really well). 

Nice tweaking
