About Primary Partition and Logical Partition
You can store your data on a hard disk only when you have partitioned the hard drive in Windows 10. There are different types of partitions such as
primary partition, logical partition and they are different from each other.
Primary partition is where operating system can be installed. Only the system is
installed on primary partition, can it boot normally. And the primary partition
where you install operating system will be marked as active partition which is used
for initial booting. Each primary partition has its own boot block.
The number of logical partitions on a hard drive depends on the type of the disk.
There are 2 disk types: MBR and GPT. As for MBR disk, you are only allowed to create
4 primary partitions or 3 primary partitions plus 1 extend partition. The extend
partition isn’t to store data, but to create unlimited logical partitions. After
creating partition, you can store data on logical drive just like primary
