A partition table is a 64-byte data structure that provides basic information for a computer’s operating system about the division of the hard disk drive (HDD) into primary partitions. A data structure is an efficient way of organizing data. A partition is a division of a HDD into logically independent sections.
Do I need partition table?

What are the types of partition table?
There are two main types of partition table available. These are described below in the #Master Boot Record (MBR) and #GUID Partition Table (GPT) sections along with a discussion on how to choose between the two.

Is Windows MBR or GPT?
Modern versions of Windows–and other operating systems–can use either the older Master Boot Record (MBR) or newer GUID Partition Table (GPT) for their partition schemes. … MBR is required for booting older Windows systems in BIOS mode, although the 64-bit version of Windows 7 can also boot in UEFI mode.
