Primary Partition or Logical?

Legacy BIOS has a limitation of 4 primary partitions and 2.2 TB per drive.

With UEFI, this limitation is now 128 primary partitions and 8 ZB (source: Wikipedia).

So you can choose either primary or logic partitions, UEFI will deal with them anyway. On my laptop, I have chosen primary partitions, it sounds proper than logic partitions on the same primary partition.

If you're booting in BIOS mode, you'll be limited by MBR's restrictions, which begin with a 4-primary-partition limit. This limit can be gotten around by creating a special type of primary partition, known as an extended partition, which serves as a placeholder for an arbitrary number of logical partitions.

If you're booting in EFI mode, you'll use GPT, which supports up to 128 partitions by default (and this value can be raised, if necessary). GPT doesn't distinguish between primary, extended, and logical partitions, although some partitioning tools still prompt for primary vs. logical status when you create partitions on GPT disk. (These tools then ignore what you say, since it's meaningless.)
