Why do modern Windows installations commonly use GPT instead of MBR? The answer is closely connected to UEFIβ€”and Windows 11 adds important firmware requirements.


Modern Windows installations generally use GPT when the computer is configured for UEFI.

For Windows 11, Microsoft requires a compatible system with UEFI firmware and Secure Boot capability as part of its system requirements. A typical Windows 11 installation therefore uses:

UEFI + GPT

Older Windows installations may still use:

Legacy BIOS + MBR

If you're upgrading an older computer or moving from an MBR-based installation to a modern UEFI configuration, you may need to change the firmware boot configuration and, depending on the setup, convert the system disk from MBR to GPT.

In this Short, learn how Windows, UEFI, GPT, BIOS, and MBR are connected.

Transcript
00:00For a modern Windows computer, GPT with UEFI is the typical configuration.
00:05For older hardware that relies on legacy BIOS, MBR may still be appropriate.
00:10For modern Windows installations, GPT is generally the preferred partition style when the computer is configured for UEFI.
00:18Windows 11 has additional hardware and firmware requirements, including UEFI firmware and secure boot capability.
00:25Therefore, a typical Windows 11 installation uses UEFI and GPT.
00:31If an older installation is using legacy BIOS and MBR, upgrading the hardware or operating system may require changing the
00:40boot configuration and potentially converting the disk.
