MBR and GPT are two formats of the hard disk. MBR is the abbreviation of master bootable record, whereas GPT is an abbreviation of GUID partition table. In order to boot Windows from GPT, the motherboard of the device should support UEFI, else, it is better to use MBR to boot from.

When installing Windows on UEFI-based PCs using Windows Setup, your hard drive partition style must be set up to support either UEFI mode or legacy BIOS-compatibility mode. You receive such an error because your PC is booted in UEFI mode, but your hard drive is not configured for UEFI mode. You’ve got a few options:

  1. Reboot the PC in legacy BIOS-compatibility mode. This option lets you keep the existing partition style. For more information on this, read this TechNet article titled Boot to UEFI Mode or Legacy BIOS mode.
  2. Wipe the drive and reformat the drive to be able to use the PC’s firmware features.
