What is GPT

According to Wikipedia, GUID Partition Table (GPT) is a standard for the layout of the partition table on a physical hard disk. Although it forms a part of the Extensible Firmware Interface (EFI) standard (Intel's proposed replacement for the PC BIOS), it is also used on some BIOS systems because of the limitations of MBR partition tables.

MBR restricts a disk and partition's size to a maximum of 2TB. While GPT allows for a maximum disk and partition size of 9.4 ZB.

More details about GPT:

  • Max size of GPT disk/partition: 9.4ZB (1ZB=1 billion terabytes)
  • Consist of GPT disk

Disk layout of GPT

1). Primary Partition Table - for system to load partition information and access to existing partition data; 
2). Normal Partition - the physical location for saving data and files; 
3). Backup Partition Table - backup of GPT header and partition table in the Primary Partition Table.

  • Operating OS Support: UEFI Boot with Windows 8/8.1/10 and newer versions.
  • Read and Write Support: Windows 10/8.1/8/7/Vista and XP(64bit only)

Why need to remove or delete GPT disk partition

Although GPT disk indeed breaks some limits of MBR disk, however, it also has shortages. For example, GPT doesn't support OS boot on old Windows systems, like Windows 7 (32bit) or Windows XP. This is one of the main reasons that many people want to remove the GPT disk partition style. Here is a list of why people need to remove, delete or format GPT partition:

  1. 1. Remove GPT disk partition style to install Windows
  2. 2. Convert GPT disk to MBR disk by removing all partitions
  3. 3. Delete single GPT partition to resolve low disk space or resize GPT disk partition
  4. 4. Format GPT partition to clear partition or reset the file system

In some cases, people may want to remove or delete the GPT disk partitions. Other computer users would remove all GPT disk partitions. If you are one of these people and have some specific needs on Partition disk or partition, check and follow the provided solutions to change or remove GPT disk partition now.
