Although GPT disk has many advantages over MBR disk, sometimes users still need to use MBR disk. For example, they  want to use a very old operating system, in this case, an MBR disk will be more suitable. Well then, how to convert GPT disk to MBR disk? You may check this post for detailed steps.

About Convert GPT Disk to MBR Disk

GPT, short for GUID Partition Table, is actually a standard BIOS partition table on a physical hard disk. Believe it or not, GPT is much better than MBR in many aspects. For instance, GPT disk supports at most 128 partitions in Windows while MBR disk supports only 4 primary partitions (or 3 primary partitions and 1 extended partition).

No wonder so many users become fans of GPT disk. But why there are still some users who want to convert GPT disk to MBR Disk?

Though GPT disk is more advanced when compared to MBR disk, users still need an MBR disk sometimes.

For instance, if users are using a very old operating system like Windows 2000 Server, a GPT disk is not suitable. Even if users employ a GPT disk in Windows 2000 Server, they can’t install the operating system to it because the booting from GPT disk is forbidden in such system. All in all, there are still some situations where users need to convert GPT disk to MBR disk.
