To use a GPT partitioning system on the hard drive what firmware is required What operating system architecture.?

To use a GPT (GUID Partition Table) partitioning system on a hard drive, UEFI (Unified Extensible Firmware Interface) firmware is required, as it supports booting from GPT disks. Operating systems that can utilize GPT typically include 64-bit versions of Windows, Linux, and macOS. While some 32-bit operating systems can read GPT disks, they usually cannot boot from them.
