2TB disk limit and allows for much faster initialization, supporting features like Secure Boot and pre-OS networking that were impossible in the legacy environment. It then reads the boot order, a prioritized list stored in NVRAM, to identify which device or application to execute next.
Bypass Boot Menu with the UEFI Boot Manager Shortcut
Unlike its predecessor, this manager provides a standardized environment with driver support, networking, and a more robust architecture that enables modern security features and complex hardware initialization. This on-screen menu is typically invoked by pressing a function key (such as F12, Esc, or another manufacturer-specific key) during the initial power-on sequence.
This chain of trust is essential for protecting against sophisticated rootkits that target the startup sequence. Secure Boot, a feature implemented within the UEFI specification, uses cryptographic signatures to verify the authenticity of boot drivers and the operating system loader.

During the Power-On Self Test (POST), it takes control after the initial hardware checks, loading drivers for hardware interfaces defined in the UEFI specification. The UEFI boot manager is the foundational process responsible for initializing a hardware platform and launching an operating system.
