Although GPT disk is more advanced than MBR disk, not all operating systems can be installed on GPT disk. When GPT disk is not supported, users would better use a professional partition manager to initialize to MBR.

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.

Here, we are going to introduce a good tool – MiniTool Partition Wizard to help with this.
