Convert Primary Partition to Logical in Windows 7 with Ease
If you are in need of converting primary partition to logical in Windows 7, read this article patiently to get effortless methods.
When we buy a new computer or want to reinstall Windows and format the whole disk at the same time, it is concerning to convert between primary partitions and logical partitions. Then, what are a primary partition and a logical partition?
◈ Primary Partition
To make it simple, a primary partition is a disk partition where both Windows OS and other data can be stored. If you want to install operating system on a disk, there must be at least one primary partition on the disk. For MBR (Master Boot Record) disk, four primary partitions can be created at most; as for GPT (Globally Unique Identifier Partition Table) disk, up to 128 primary partitions can be created. However, only one primary partition can be set active for the system to boot.
◈ Logical Partition
After creating 3 primary partitions in an MBR disk, the rest storage space can be used as an extended partition. In general, you can use all the rest space on the disk to create an extended partition, but surely you can choose not to use all. However, an extended partition cannot be used to store data until a logical partition is created in it. An extended partition can be divided into multiple logical partitions. It’s inclusion relation between an extended partition and a logical partition, that is, all logical partitions are parts of the extended partition.
To sum up, a primary partition can be used to install Windows while a logical partition is mainly used to store data. What’s more, a primary partition can be set active for the system to boot while a logical partition cannot.
As it is mentioned above, MBR disks allow for the maximum number of four primary partitions. Apparently, four partitions are not enough for some users. At this time, it is required to change a primary partition to extended and create logical partitions in it as many as you need.
A logical partition acts as a storage medium. It has nothing to do with operating system and other logical partitions or primary partitions. It is “independent”. Changing primary partition to logical in Windows 7 not only makes it convenient to store files by category but also provides a destination path for file backup.
To convert primary partition to logical in Windows 7, here are two effortless methods I’d like to recommend:
1. Click Start and type “diskpart”. Right click on diskpart and select “Run as administrator”.
2. Type list disk and press Enter.
3. Type select disk # (ex: disk 1) to select the disk where you want to change primary partition to logical and press Enter.
4. Type create partition extended to create an extended partition using all the unallocated space on the disk and press Enter.
5. Type create partition logical to create a logical partition using all the space on the extended partition and press Enter.
6. Type format quick to format the partition quickly and press Enter.
7. Type assign letter=# (ex: letter=F) to assign a drive letter and press Enter.
8. Type exit to exit Diskpart and press Enter.
As you see, you cannot convert primary partition to logical directly via Diskpart. Instead, you create an extended partition with the unallocated space first and then create logic partitions in the extended partition. The process is complex and may cause data loss.
