![]() UEFI uses GUID Partition Table(GPT) to keep the information related to boot-loader and partitions.Ī traditional GUID partition scheme might be a bit complex for you to understand so I will try to explain the basics of it:Īs per above image you can see what a GPT disk contains: GPT is a partition table layout for storage devices such as hard disks and SSDs. Basically, GPT and MBR are two types of partitioning tables. Partition tables are also responsible for storing and organizing data. Partition tables store partitioning information. Every storage disk has partitions and to keep the track of the beginning and end of each partition, we need partition tables. When you install a new storage disk on your computer, you get an option of whether you want it to be MBR or GPT. So let’s understand GPT, and MBR first as they play some important role in the starting process of a computer. Understanding these terms will help you to know more about the storage drives we use and how they work. In this article, you will learn what is GPT, MBR, NTFS, and FAT32. Earlier we have talked about BIOS, UEFI firmware, and which firmware works with MBR and GPT.
