Why UEFI boot will be faster than Legacy BIOS boot

UEFI Bios supports two boot modes: Legacy+UEFI boot mode and UEFI boot mode, Legacy+UEFI boot mode refers to the UEFI and legacy BIOS ****existing modes, which are compatible with legacy BIOS boot modes for booting the operating system; UEFI boot mode is just to boot the operating system in UEFI boot mode.

Tips:

1. Once the boot mode is selected and the operating system is installed, only the set mode can be used for booting the operating system after installation.

2. The operating system is installed using Legacy+UEFI mode, which is compatible with booting the operating system in legacy BIOS boot mode.

3. If the operating system is installed using UEFI boot mode, the operating system can only be booted in UEFI boot mode.

The difference between Legacy+UEFI mode and UEFI mode

1. Legacy+UEFI boot mode is based on the fact that some computer hardware devices and operating systems (such as WinXP/7) do not yet support UEFI-based BIOS, and consider booting from a traditional BIOS boot mode. Legacy BIOS boot modes allow Hba, and modular devices use the Rom option.

2. UEFI boot mode is used to automatically load the operating system from a pre-booted operating environment to an operating system, thereby simplifying the boot process and saving time. And support for more than 2T hard disk, to strengthen the support for hardware, Win8 is the reason why the boot speed, and Win8 native support UEFI mode is not unrelated!
