6 down vote I wouldn't suggest using  diskpart  if the hard drive already has some data on it, especially if you've installed the system on it. This is because if you don't know how to use it, then it's better to avoid using it to prevent you from data loss. You can use a third part tool to do that instead, which will give you the same results. Use  EaseUS Partition Master  (Free Edition), or visit  the Best Free Partition Management Software  page to have other tools. In case you still prefer to do it the long way, using  diskpart , follow these steps : Open the Command Prompt as Administrator. Type  diskpart  and hit Enter. Once you enter to the diskpart screen type  list disk  and hit Enter. Now a list of the disks will be shown, type  select disk x  (the X is the disk number that has an unallocated space) and hit Enter. Now, type  create partition primary size=x  (The X is the number that you got from the Free column on the previous step) and hit Enter.
