Uefi is no different from traditional bios startup.

The difference between UEFI and Legacy+UEFI boot mode. Many users who reinstall the computer operating system have to deal with Bios if they boot with CD-ROM. Many users will find that there are two modes when they enter the BIOS setup boot mode, namely Legacy+UEFI and UEFI. Therefore, Bian Xiao will tell you the difference between them here, and interested friends can have a look!

First, UEFI Bios startup mode

UEFI Bios supports two startup modes: Legacy+UEFI startup mode and UEFI startup mode, where Legacy+UEFI startup mode refers to UEFI and traditional Bios*** storage mode, which can be compatible with traditional BIOS boot mode to start the operating system; UEFI Boot Mode Starts the operating system only in UEFI Boot Mode.

Tip:

1. Select the boot mode and install the operating system. After installation, you can only use the set mode to start the operating system.

2. Legacy+UEFI mode is used when installing the operating system, which is compatible with the traditional BIOS boot mode to start the operating system;

3. The operating system is installed in UEFI boot mode, and the operating system can only be started in UEFI boot mode.

Second, the difference between Legacy+UEFI mode and UEFI mode

1 and Legacy+UEFI boot modes are based on the fact that some computer hardware devices and operating systems (such as WinXP/7) do not support UEFI BIOS, so consider starting with the traditional BIOS boot mode. Traditional BIOS boot mode allows Hba and module devices to use Rom option.

2.UEFI boot mode is used to automatically load the operating system from the pre-boot operating environment to the operating system, thus simplifying the boot process and saving time. And support more than 2T hard disk, strengthen the support for hardware. The reason why Win8 starts fast is not unrelated to Win8' s native support for UEFI mode!
