Use Diskpart to Change Partition Type |Yes or No?
Want to change partition type to primary or logical? Except for Diskpart, you have better way to change partition type without formatting on Windows PCs.
Before you figure out is it possible to change partition type through Diskpart, it is better to learn what partition type is.
Theoretically, partition type is a byte value intended to specify the partition contains and/or to flag special access methods used to access these partitions. That is an answer from Wikipedia. Do not understand clearly? Don’t worry, you’ll see partition type in Disk Management marked as Primary partition and Logical partition.
Files like bootmgr and ntldr to boot Windows should be saved in a primary partition. Also, in MS-DOS and earlier versions of Microsoft Windows systems, the first partition (C:) must be a primary partition.
Please note that the Logical partition concept only exists in MBR disks. Therefore, the disk must be an MBR disk if you see Logical words in Disk Manager. Besides, if you want to change a partition type from Primary to Logical, make sure that your disk is MBR style (If not, convert to MBR first).
As different types of partitions have different features, you may need to change partition type:
If you want to create more partitions on an MBR disk which owns 4 primary partitions already, you can set one of primary partitions to extended/logical since an extended partition can hold multiple logical partitions.
When there have been 3 primary partitions and 1 extended partition, creating partition from unallocated space will convert the current disk to dynamic one. In this situation, converting one of primary partitions to logical is an ideal method too.
It is possible to set up dual boot operating system by changing an existing logical partition if there’s no other primary partition.
While there could be many other reasons as well, now the question is how to change partition type?
The fact is that even Windows 10, which has been improved much compared with early versions, doesn't provide features of using Diskpart change partition type. Neither in its Disk Management.
