Convert system disk from MBR to GPT safely
In computer hardware, 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, which restrict a disk and partition's size to a maximum of 2TB. GPT allows for a maximum disk and partition size of 9.4 ZB.
In some cases, people may want to remove or delete the GPT disk partitions. Some computer users want to remove single GPT disk partition for their special needs. For example, the first partition is low disk space, while the second partition is not used yet. If so, he can remove the second GPT disk partition and extend the first one. For detailed steps of extending GPT disk partition, please refer to resize GPT disk partition with the unallocated space.
Other computer users would remove all GPT disk partitions. For example, convert GPT disk to MBR disk. As they are two different partition table styles, if you want to convert GPT disk to MBR disk, you need to remove all partitions on the GPT disk before converting.
