What is uefi windows?

UEFI (Unified Extensible Firmware Interface) is a type of firmware that has replaced the traditional BIOS (Basic Input/Output System) in most modern computers, including those running Windows. This new firmware provides more advanced features such as faster boot times, support for larger hard drives, and improved security.

UEFI has become the industry-standard firmware for all modern Windows PCs, including those running on Intel, AMD, and ARM-based processors. It works by providing a standardized interface for booting the operating system and managing hardware configurations.

UEFI-based Windows systems typically use GPT (GUID Partition Table) for partitioning the hard drive, which allows for larger volumes and more flexible partition management. In addition, UEFI provides a secure boot process that prevents unauthorized firmware or operating system code from running at boot time.

UEFI is also compatible with Windows 10’s fast startup feature, which allows the system to start up more quickly by saving the system state and restoring it on the next boot. This feature is only available on systems that use UEFI firmware.

Overall, UEFI has become an important part of modern Windows systems, providing improved performance, security, and flexibility compared to traditional BIOS-based firmware.
