Yes. It’s possible in this version of Windows to repartition your hard disk by using the Shrink feature in Disk Management. You can shrink an existing partition or volume to create unallocated disk space, from which you can create a new partition or volume. (Often, the terms partition and volume are used interchangeably.)

For detailed information on how to shrink a volume, open Disk Management, click Help on the menu bar, click Help Topics, click the Contents tab, click Disk Management: Welcome, click Manage Basic Volumes, and then click Shrink a Basic Volume.

Notes

• If you have multiple partitions on your hard disk, you can delete and create partitions from the resulting unallocated space. When you delete a partition, all data on the partition will be erased.
• You can also repartition hard disks with a third-party partitioning program. Several third-party manufacturers offer programs that allow you to repartition your hard disk without erasing data.
