The question “how to change GPT partition to NTFS” was discussed in many forums now and then. However, some people don’t know the difference between GPT and NTFS.

Let me be very clear at the start, GPT and NTFS are two different items. A disk on a computer is usually partitioned in either MBR or GPT (two different partition table). Those partitions are then formatted with a file system, such as FAT, EXT2, and NTFS. Most disks smaller than 2TB are NTFS and MBR. Disks larger than 2TB are NTFS and GPT.

One situation is about installing operating system. Some people receive error messages like “the hard disk is in GPT, please enable the bios to boot...” and “Windows cannot be installed on GPT partitions. Windows must be installed on an NTFS formatted partition” when they install Windows XP or Windows 7.

We should know first that Windows XP can’t be installed on a GPT partitioned hard drive because Windows XP doesn’t support it.

As for Windows 7, make sure your motherboard is equipped with UEFI (about UEFI/BIOS, please visit Legacy VS UEFI VS Legacy+ UEFI). Then you can boot the Windows DVD, partitioning the drive with GPT, and installing Windows on an NTFS partition.

Another situation is about “GTP Protective Partition”. Suppose you have an external hard drive, and you hooked it up to your PC, but it has a description "GPT protective partition". And you are unable to reformat it to NTFS.

In either case, the first thing we should do is converting GPT to MBR, and applying the NTFS format for backward compatibility.

How to convert? One way is with diskpart command. Another way is with the help of AOMEI Partition Assistant Professional Edition. AOMEI Partition Assistant has a powerful function named “Convert to MBR Disk”. It can solve the problem easily and securely because it has a clear demonstration on every step. Now, see how it works.
