The Differences between GPT and MBR

In case some users are not familiar with GPT and MBR, we'd like to tell you the basic knowledge of these two terms and differences between them.

Both MBR and GPT are partition styles that apply to Windows computers. MBR was introduced a bit earlier than GPT. It was first introduced in 1983, while GPT didn't appear until the late 1990s.

  • Different Structures

One noticeable difference between GPT and MBR is the structure. MBR consists of three parts: master boot code, a partition table for the disk, and the disk signature. GPT has a more complex structure, for it contains more components than that of MBR. If you want to know the detailed information, you can read MBR vs GPT for further exploration.

  • Different Partition Amounts

Another difference is the supported partition amounts. MBR only supports users to build 4 primary partitions at most. If you want to create more partitions, you need to create an extended one. In a GPT disk, the number of primary partitions is almost unlimited. On a Windows computer, you can create a maximum of 128 partitions on a GPT.

  • Different Boot Mode

The boot mode of theses two partition styles is different. With an MBR disk, you need to boot your Windows in BIOS mode, also called Legacy boot mode. With a GPT disk, you can only boot your Windows in UEFI mode.

The Bottom Line

As you can see, to convert a GPT to MBR, the safest and most reliable method is to seek help from EaseUS Partition Master. It not only supports conversion between GPT and MBR, but also supports to convert a basic disk to a dynamic one, switch the file system from FAT32 to NTFS, and change a logical partition to a primary partition, etc. With EaseUS Partition Master, partition management will be much easier.
