I am running Vista Home in a new Dell desktop machine. The machine came with the following partitions: EISA - Primary C (OS) - Primary D (Recovery) - Logical I used DDS10 and made the following changes: EISA - Primary (no change) C (OS) - Primary (changed size only) D (Applications) - Primary (new) E (Recovery) - Logical (changed drive letter) G (Data) - Logical (new) I would like to make the G partition a primary partition using the DDS10 conversion process. However, only logical is available. The E partition in also a logical partition, however, DDS10 provides to option to convert this partition to primary. Question: Why will DDS10 allow me to convert partition E to primary but not partition G?
