Why I have the ‘The selected disk is of the GPT partition style’ problem?

First things first, you might want to know what the GPT partition style is.

A disk needs to be partitioned to be used. MBR (Master Boot Record) and GPT (GUID Partition Table) are the two partition types of hard disk to store the partitioning information on the disk. MBR is the traditional style and compatible with most systems. A MBR disk uses the standard BIOS partition table. For the GPT, it’s a news standard which is gradually replacing MBR. A GPT disk uses UEFI partition table, which replaces the old BIOS in turn.

By now, you may have a brief understanding of GPT and MBR. If the Windows system you’re installing is BIOS based which requires to be installed on MBR, and your orginal system is with GPT partition, then the problem “Windows cannot be installed to this disk. The selected disk is of the GPT partition style” appears.
