1. Right click on the space listed as unallocated.
2. At the menu that comes up, click on the New Partition option.
3. You will now be presented with a wizard as to how you would like the partition to be created. At the first screen press Next.
4. At the following screen, determine if you need a primary or extended partition. For more information about these partitions you can read our partition tutorial listed above. Most people will be fine selecting Primary Partition. Select Primary Partition and press Next.
5. You will be prompted to type in how much of the unallocated space you would like used for the new partition. In my example, my unallocated space is 26.43 GB, so I can choose to make a partition of that entire amount of only use half and save the rest for another partition. Regardless, of what you decide, you need to enter a size in the Partition size in MB: field, or stick with the default size, and press the Next button.
6. At the next screen, select the drive letter you would like assigned to it, or use the default one given. When done, press the Next button. The drive letter that you assign here will be how you access the partition later.
7. For the most part you are advised to use the NTFS file system. If you need a file system that can be readable by older operating systems like DOS, Windows 95, Windows 98, or Windows ME, then you should instead choose the FAT32 file system.
8. Type a name in the Volume Label field that will be associated with this partition or leave it blank.
9. Finally press the Next button and you will come to a summary screen. Review how the partition will be created, and if you are satisfied, press the Finish button to complete the creation and formatting of your new hard disk partition.
