How to Create New Partition in Windows 7 without Formatting and Reinstalling?

You can take advantage of the hard disk to create partition for different usages. For example, one is for your Windows 7 operating system and the others are used for storing files, games and movies, etc. We advise you to create at least two partitions in Windows 7 to easily handle the data and system separately. Then, how to create partition in Windows 7?

In most cases, you are able to create partition with Windows 7 Disk Management snap-in. To create partition, you need to be well aware that MBR disk is limited to 4 primary partitions, or 3 primary partitions and 1 extended partition which can contain multiple logical drives. Otherwise, you may encounter two symptoms when trying to create partition in Windows 7 with Disk Management.

Symptom 1: "You cannot create a new volume in this unallocated space because the disk already contains maximum number of partitions".

Error Message 1

The above error message appears because there are already three primary partitions and one extended partition on Disk 0. Therefore, you can not create partition any more. In order to create more partitions, you have to reinstall Windows 7 and format hard drive. However, the latest Partition Magic Windows 7 software allows you to create more partitions without formatting and reinstalling.

Symptom 2: "The operation you selected will convert the selected basic disk(s) to dynamic disk(s). If you convert the disk(s) to dynamic, you will not be able to start installed operating systems from any volume on the disk(s) (except the current boot volume). Are you sure you want to continue?"

Error Message 2

The above error message appears (especially in HP OEM computer) because there are already four primary partitions on Disk 0. Therefore, you can not create partition any more unless converting to dynamic disk. However, you can only revert back to basic disk by deleting all the volumes on dynamic disk. Therefore, you must NOT click "Yes". Partition Magic Windows 7 software can help you create more partitions without converting to dynamic disk.
