“There are four primary partitions (system reserved, C, D, E) and some unallocated space in my Windows 10 laptop. Now I need to create two new partitions to store my different types of data. Someone advices me to convert partition to logical to achieve this aim. But how can I do it without losing data?”
As you know, primary partition and logical partition are two different partition types. To install operation system, there must be a primary partition at least. The logical partition is a part of extended partition, in other words, a extended partition can contain many logical partitions.
As to a MBR disk, there are at most four primary partitions, or three primary partitions plus one extended partition which includes many logical partitions. If there are already four primary partitions on your MBR disk, and you want to create more partitions to store data by category, you need to change one primary partition to logical and then release some unallocated space to create a new partition. As the above situation mentioned, is there any way to do this task without data loss? Of course, a very professional partition management software is your choice. Please read on.
Convert to Logical Partition with Disk Management
Before introducing a safe way, there is an unreliable way you need to know. You may say Windows built-in Disk Management can be used to create a logical partition. In fact, if there are four primary partitions on a MBR disk, you can use Disk Management “Delete Volume” feature to delete a primary partition and then create a new simple volume.
After creating a new volume, this volume will become a logical partition automatically. Then you can shrink this logical volume to get some free space and create a new partition. But this way makes your data loss, and you must backup data previously.
