What Are MBR Disk and GPT Disk

The hard disk is a kind of storage media installed in the computer. In general, there are two hard disk styles: MBR disk and GPT disk. MBR which is short for Master Boot Record and GPT which is short for GUID Partitioning Table are two different disk partition tables. MBR disk only supports hard disk no larger than 2 TB and up to four primary partitions or three primary partitions plus one extend partition; GPT disk can manage hard disk larger than 2TB and supports up to 128 primary partitions in Windows Operating System. Besides, MBR disk boots from legacy BIOS, while GPT disk boots from UEFI.

MBR disk is widely used nowadays. But in the era of information explosion, more and more data will be saved to the hard disk. With time goes by, the hard disk will be run out of space.

On the other hand, if you want to create more than four primary partitions on your hard disk, or you have to boot your hard disk from UEFI, the only thing you could do is to convert MBR disk to GPT disk. Is there any way which can convert MBR to GPT free in Windows 7? The answer is yes. Let's look the following content.
