How to Initialize to MBR Disk [MiniTool Wiki]

About Initialize to MBR Disk

We found an increasing number of users now would like to initialize their disk to MBR, due to the following reasons:

  • No UEFI option is offered in BIOS, operating system has to be installed on MBR disk.
  • Operating systems like Windows 7 32-bit and Windows Vista 32-bit do not support GPT disk.
  • Some programs do not support GPT disk.

However, if users need to mount a second operating system to the GPT disk, they may be disappointed. The reason is simple – common BIOS system doesn’t support booting from GPT disk. In this case, users may need to initialize to MBR disk sometimes so as to keep both operating systems.
