How to Partition a Hard Drive on Windows 10/8/7 without Formarting

Windows 7 and later systems have built-in partitioning tool, Disk management. In order to partition a hard drive, we need to shrink an existing partition and split out the extra space for a new partition.

  • Step 1. Go to Start menu (or search box if no Start menu), then type: partitions.
  • Step 2. Click Create and format hard disk partitions from the match results.
  • Step 3. Check the columns at the bottom. Right-click the partition that has extra space, then choose Shrink volume

  • Step 4. Enter the amount of space to shrink, then click Shrink. Once it is done, a new unallocated column will appear.
  • Step 5. Right-click the unallocated volume and choose New Simple Volume

  • Step 6. Follow the New simple volume setup wizard. The default settings are usually fine.
  • Step 7. Now you should get a new partition on your hard drive.

Notes:

  1. If there already exists Unallocated space, then you can skip Step 3 and 4.
  2. If it is an initial partitioning or setup of your hard drive, you may be asked to choose a partition style for the new hard drive. Check the differences between MBR and GPT.
