MBR and GPT are two different partition tables. Many users are confused about the question of can MBR and GPT on same disk. So, we share this article from MiniTool Partition Wizard to clear your doubts about MBR and GPT.

Brief Introduction of MBR and GPT

MBR is the abbreviation of Master Boot Record. It uses Legacy BIOS and supports 4 primary partitions or 3 primary partitions plus 1 extended partition. The maximum addressable storage space of an MBR partition table is 2TB.

GPT is the abbreviation of GUID Partition Table, which supports up to 128 primary partitions in Windows using UEFI BIOS. GPT disks place no practical limit on the size of the hard drive.

MBR and GPT disks are two popular partition styles on Windows-based computers. They are layout standards for storage devices such as HDDs or SSDs.

In general, GPT was originally designed to break through the limitations of MBR, especially storage limitations.

Can MBR and GPT on Same Disk

Sometimes, you may have a question: can you mix MBR and GPT drives? MBR and GPT are two different hard drive partition styles. As we all know, before we can store any data, there must be partitions on the hard drive. However, a hard drive must be initialized to a certain partitioning style (MBR or GPT) before it can be divided into partitions.

Therefore, a disk can use either MBR or GPT, but not both. In other words, it is not possible to mix MBR and GPT on the same disk.

Recommendation: Convert MBR/GPT Without Data Loss

Although you can use MBR or GPT on the same disk, there are a few reasons why you might want to make the conversion. The most common tools are the Windows built-in Disk Management and DiskPart. But they can only convert empty disks to MBR/GPT and need to delete all existing partitions before conversion.

Therefore, we recommend using MiniTool Partition Wizard to convert to MBR/GPT as it will keep your data safe and intact. This means you can convert your hard drive directly without deleting any partitions.

If you want to convert the system disk to MBR, it is best to use the MiniTool Partition Wizard Bootable Editon to convert the system disk and back up the system disk in advance.

Here we take a non-system disk as an example to show you how to convert MBR to GPT without data loss. Alternatively, you can convert GPT to MBR with this software.
