Convert MBR disk to GPT disk

  • It is not an easy operation to convert MBR disk to GPT disk since it relates to the safety issue of entire disk which would crash due to even one small mistake. Compared with MBR, GPT enjoys more advantages, this is why users want to convert MBR disk to GPT disk. To realize this operation, user is recommended to utilize an excellent partition manager such as MiniTool Partition Wizard.

    MBR and GPT disks
    The full name of MBR is Master Boot Record.
    To facilitate understanding, MBR is defined in both narrow and broad sense: broadly, MBR contains entire sectors, namely the above-mentioned Master Boot Record; narrowly, MBR merely refers to bootstrap programs. MBR doesn't belong to any operating systems; the disk operation command provided by operating system can not access MBR but modify or rewrite it. For instance, in minix3, command: installboot -m /dev/c0d0 /usr/mdec/masterboot could write masterboot, a little program, into MBR.
    Compared with MBR, GPT enjoys more advantages since it allow 128 partitions at most and applying primary disk partition table and backup disk partition table in redundancy, supports a maximum volume size of 18GB and the only disk and ID(GUID).
    A single dynamic disk group can have both MBR and GPT disks and create mirrored volume, striped volume, spanned volume and RAI-5 volume.
