When you Delete a hard disk partition (volume) you turn that partition into a unallocated (unformated) partition. You can then use this unallocated partition to Extend another partition to a larger size. For more information, see: Windows Help and How-to: Partition and Understanding Disk Partitioning
A type of partition created on a hard drive that can host an operating system and functions as though it were a physically separate hard drive. Also called a volume. Only up to four primary partitions, or 3 primary partitions and 1 extended partition can be created on a single hard drive. Primary partitions can be used to install and start an operating system. If you want to create more than three partitions, the fourth partition is created as an extended partition.

A type of partition on a hard drive that should be used if you want to create more than four Primary partition. Extended partitions can contain multiple logical drives that can be formatted and have drive letters assigned to them. An extended partition is a container that can hold one or more logical drive. Logical drives function like primary partitions except that they cannot be used to start an operating system. This option has been removed in Disk Management for Vista.

This can be handy, for example, if you have one hard drive with two partitions and would like to Delete the second partition and Extend the first (boot) partition with Vista back to one large partion (volume).
The default location for Disk Management is C:\Windows\System32\diskmgmt.msc.
- You will not lose any data on the partition (volume) that you are Extending. The partition you want to delete and use to extend another partion must be to the immediate right of the one you want to extend. You can cannot extend a partition from a deleted partition two or more partions to the right of it.
- All data on a partition will be lost when you Delete it. Be sure to back up any files that you want to save to a different location before you continue.
STEP ONETo Delete a Partition
1. Open the Control Panel. (Classic View)
A) Click on the Administrative Tools icon.

4. Right click on the volume (EX: E:\ ) you want to delete that is just to the right of the partition that you want to extend, and click on Delete Volume.
NOTE: If your hard disk is currently set up as a single partition, then you cannot delete it. You also cannot delete a system partition (OS isntalled on), boot partition, or any partition that contains a virtual memory paging file, because Vista needs this information to start correctly. You will have to use the Vista installation disk to delete it.

WARNING: It is advised that you do not extend a volume on one disk with free space from another disk. If one of the drives has a hardware failure, then all the data on that partition (volume) will be deleted.
