If your computer is UEFI-based, you should choose the GPT partition style.

If you have read the content above, you would understand that whether to choose MBR or GPT has nothing to do with the type of your hard disk. MBR vs GPT, Which One is Better for An SSD?

For example, users could install both Windows and Linux on their computers. Partitioning a disk can also help users to create multiple bootable partitions with different operating systems. In this case, it means that you can format the system partition and reinstall the operating system without affecting any data on other partitions. For example, you can partition a 2TB disk into one bootable partition to install OS and applications, and one data partition to store data. To partition a hard drive is actually to process a virtual split of physical hard disk storage space.

Third, MBR can support up to 2TB, while GPT can handle unlimited storage space.

Second, users can only create four primary partitions in MBR but can create a maximum of 128 primary partitions in GPT.

First, MBR can only boot in BIOS, and GPT can only boot in UEFI.

In general, there are three differences between MBR and GPT. Generally, the number of primary partitions in a GPT disk is unlimited, you can create as many partitions as you want (You can create a maximum of 128 partitions on a GPT, but it is unlikely that you would ever be in such a situation). And it is not only more compatible than MBR but also supports larger memory than MBR. GPT needs a UEFI-based system to boot from. It is a more advanced and novel partition style, which didn't appear until the 1990s. Inside the extended partition, you can create logical partitions to circumvent the partition amount limitation.

MBR only supports users to build 4 primary partitions, or three primary partitions, plus one extended partition. MBR needs to boot from BIOS, and it only works with a maximum size of 2TB on a disk.

The master boot code stores the installed OS information and a short boot code. MBR consists of three parts: master boot code, a partition table for the disk, and the disk signature. MBR stands for Master Boot Record, it is the traditional partition style that first came up with by IBM in 1983.

How to Convert MBR to GPT Brief Introduction of MBR and GPTīoth MBR and GPT are partition styles that apply to Windows computers. What is Disk Partition? Why Need to Partition a Disk? And most of the computers are equipped with an SSD now, then which partition style is better for this kind of disk? To answer this question, you need to know what is partition style and the differences between MBR and GPT. Most users have no idea what's the difference between these two partition styles.

When installing and reinstalling the Windows OS on the hard drive, users will be required to choose between two partition styles, namely MBR and GPT. If you need to switch from MBR to GPT, or GPT to MBR, you need to back up your data ahead of time to avoid losing all of the data on the hard drive when you format it.įor more information on this subject and Windows, refer to the following Microsoft knowledge base article. If you have a hard drive that you would like to boot from and it is larger than 2 TB, you can select GPT (GUID), but you will also need to be running a supported operating system and the system's firmware must be UEFI, not BIOS. If you have a hard drive that you would like to use but not boot from and it is larger than 2 TB, select GPT (GUID). If you have a hard drive that you would like to use and it is 2 TB or smaller, select MBR when you initialize the hard drive for the first time. The maximum hard drive size of GPT is 9400000000 TB, with sector sizes of 512 (the standard size for most hard drives at this time). The G stands for GUID (Globally Unique Identifier), and the P and T stand for Partition Table. To remedy this, the GPT format was introduced. As such, if you have a 3 TB hard drive and you use MBR, only 2 TB of your 3 TB hard drive will be accessible. The maximum hard drive size of MBR is 2 TB. MBR stands for Master Boot Record and was the default partition table format before hard drives were larger than 2 TB.
