On EFI systems, Windwos can only be installed to GPT disk” during OS installation. That’s why you receive the error messages “Windows cannot be installed to this disk, The select disk is of the GPT partition style”, or “Windows cannot.The selected disk has an MBR partition table. Similarly, if the motherboard supports UEFI mode only, you can only boot OS from GPT disk. Namely, if the motherboard of your PC supports Legacy mode only, you can only boot Windows from MBR disk.
The MBR goes hand in hand with Legacy boot while GPT is with UEFI boot. Besides, the GPT supports disk up to 9.4ZB in size, allowing you to fully utilize disk that is larger than 2TB. You can create a nearly unlimited number of primary partitions on GPT-based disk, no need to create an extended partition. However, the newer partition style GPT breaks out the MBR’s limits. Besides, the MBR only works with disk up to 2TB. If you need more, you have to make one of the primary partitions an “extended partition” in which you can create unlimited logicial partitions. MBR only supports up to 4 primary partitions. GPT (GUID Partition Table) was developed by Intel in the late 1990s as part of what eventually became the Unified Extensible Firmware Interface and it becomes quite pupular nowadays, tending to take the replace of MBR. MBR (Master Boot Record) was introduced with IBM PC DOS 2.0 in March 1983 and it is the most compatible one. Refer to the following content on MBR VS.
