Extended partition cannot store data directly, and logical partition should be created on extended partition. MBR partition table saves information about primary partition and extended partition only. Extended partition and logical partition are introduced for the purpose of breaking through the limit that MBR can have 4 primary partitions at most.ģ. There are three kinds of partitions on MBR disk: primary partition, extended partition and logical partition. The 64 bytes in the first sector is used to save partition information, and each partition requires 16 bytes.Ģ. There are 4 primary partitions at most on MBR disk. The following picture shows MBR partition scheme.ġ. Users can create multiples logical partitions in an extended partition. To eliminate this limitation, extended partition is introduced. But many users are not satisfied with 4 partitions and want to create more partitions. That is to say MBR partitioning can have up to 4 partitions. The entry for each partition is 16 bytes and the total is 64bytes, thus the maximum entries MBR partition table can save is four. MBR partition table scheme saves partition information on the first sector of disk. If Linux operating system is installed on the disk, the MBR holds the grub boot loader.

Thus, sometimes you may need to rebuild MBR when it is damaged or Windows cannot boot. If Windows is installed on the disk, the initial bit of the system boot loader is located here.

The boot loader holds a little piece of code which will load another larger loader from other partition on the drive. It is at the beginning of a hard drive, working as a special boot sector which includes a boot loader for the installed Windows and information recording logical partitions of the hard drive.

MBR, short form of Master Boot Record, was initially introduced with PC DOS 2.0 operating system in 1983. There are two types of partition plans: MBR and GPT on Windows computer, and we'll talk about both in the following sections. However, if you haven't heard about the concept, it's able to help you understand partition table and its function directly.

Actually, this picture can't present actual situation accurately, and some details are even not right. In the picture above, hard drive is divided into three partitions C, D and E, and partition table information is stored in disk's beginning part. Operating system gains partition information by way of accessing data in partition table. Partition table defines and stores partition information, locating certain disk space on the beginning area.

How to create multiple partitions? This is when partition table come to use. One physical hard drive or SSD can be divided into several partitions (it is OK to have one partition only). Partition should be formatted to NTFS or FAT files system before storing data. Strictly speaking, partition can't store data if files system is not built. If you want to know more about these, please continue reading.Ĭomputer contains at least one hard drive or SSD for data storage, but the physical drive can't store data directly before partitions are created. BIOS does not support GPT-partitioned volumes. If the motherboard uses legacy BIOS system, you should choose MBR. If the motherboard on your computer supports UEFI (Unified Extensile Firmware), you can choose GPT.ģ. If the capacity of your hard drive exceeds 2TB, you should choose GUID partition table (GPT) partitioning scheme, so that you can make use of all storage space.Ģ. If you just want to know how to choose between MBR and GPT instead of learning technical details, then follow advice below:ġ. This part sums up several rules that can help you decide which to choose. When installing operating system, you might be asked whether you want to use MBR or GPT partition table format.

MBR VS GPT, which one is better for you?.Two types of partition plans - MBR & GPT.
