MBR disk uses a master boot record disk partition system which contains a master boot record (MBR for short). MBR includes operating system boot code, master partition table and exit code. Master partition table is used to record some basic information of disk partition and boot operating system to help users find desired partition. MBR disk supports 4 primary partitions or 3 primary partitions and 1 extended partition, and the biggest partition size can reach 2TB. MBR is the most widely-used disk type, and also the default type of newly-added disk under Windows operating system. When you mount a new disk in Windows operating system, Windows operating system will guide you to initialize new disk to MBR disk. However, what if we mount an initialized GPT disk and we want to initialize GPT to MBR? There are two common ways to initialize GPT disk to MBR disk. That is to use Disk Management Tool and the third-party partition magic like MiniTool Partition Wizard.
Take Windows Server 2003 for example, I will initialize GPT disk to MBR disk with Disk Management Tool (Utility) below:
1. Click "start".
2. Select "My Computer" on pop-up menu and right click.
3. Click "Management" on pop-up menu.
4. On the computer management interface, click "Disk Management" on the left storage unit to see interface below:
5. Delete all partitions on GPT disk.
6. After that, select GPT disk and right click, and then click "Convert to MBR Disk" on pop-up menu.
Performing steps above, we will initialize GPT disk to MBR disk on Windows Server 2003. Because Disk Management Tool of Windows Server 2003 only can delete partition one by one, it's troublesome if you have many partitions.
Note: Because deleting partition will cause partition data loss, please back up data before deleting GPT disk partition.
