What is the difference between GPT and MBR mode when partitioning a hard disk?

When partitioning a computer's hard disk, especially when installing Windows 10, the user will find that the system asks him if he wants to use MBR or GPT in partitioning the hard disk, as MBR and GPT are two different ways to store partition information on a drive, this information includes where the partitions start and end on the physical disk, and below we explain the difference between GPT and MBR to show the appropriate type for a personal computer as follows.

What is the difference between GPT and MBR when partitioning a hard disk?

GPT offers a range of advantages, but at the same time, MBR is more compatible and still necessary in some cases, as GPT, or GUID Partition Table, is a newer standard that has many advantages including support for large drives and is required by most hardware devices. Modern computer.

MBR stands for Master Boot Record because it is a special boot sector located at the beginning of the drive. This sector contains a boot loader for the installed operating system and information about the drive's logical partitions. The boot loader is a small piece of code that generally loads the larger boot loader. From another partition on the drive.

And if you have Windows installed, you'll find here the raw parts of the Windows boot loader that's why you might have to repair the MBR if it's overwritten and Windows won't start, MBR only works with disks up to 2TB, and MBR also supports up to four Basic Partitions Only If you want more, you should make one of the basic partitions an “extended partition” and create a logical partition inside it.

The difference between GPT and MBR when partitioning a hard disk?

GPT is a new standard that is gradually replacing MBR, it is related to UEFI, which replaces the old BIOS with something more modern, and GPT, in turn, replaces the old MBR partition system with something more modern, called GUID Partition Table because each partition on the drive has an “ID Globally Unique” or GUID – A random string so long that each GPT partition is likely to have its own unique identifier.
