MBR and GPT are two formats of the hard disk. MBR stands for Master Boot Record, and GPT stands for GUID Partition Table. It is the traditional partition structure to manage disk partitions. It is widely used by a majority of users due to its compatibility with most systems.

GPT partition style is a newer standard for disk partitioning, which defines partition structure by GUID. It is part of the UEFI standard, which means the UEFI-based system should be installed on a GPT disk. 

Boot Windows from GPT, you should do two things. First, make sure your PC is booted in UEFI mode. Second, make sure that the motherboard of the device supports UEFI. If not, it is better to use MBR to boot from.

So, when you get “The Selected Disk is of the GPT Partition Style” error in Windows 10/8/7 or other previous Windows versions, please first check if your PC is booted in UEFI mode. If no, please do it.

Steps to boot into UEFI mode:
