What do the installed version and UEFI version mean respectively?

Simply put, the installed version is the version installed normally. UEFI version is specially designed for new computers started by UEFI. This startup method has certain advantages, but it is only supported by the BIOS of the new computer motherboard.

There are bios settings in the computer, which are mainly responsible for detecting hardware functions and booting the operating system. Uefi is used to automatically load the operating system from the pre-boot operating environment to the operating system, thus saving boot time.

BIOS running process: boot -BIOS initialization -BIOS self-check-boot the operating system-enter the system.

UEFI operation flow: boot -UEFI initialization-boot operating system-enter the system.

Advantages of UEFI startup-

1, security.

UEFI startup needs an independent partition, which isolates the system startup file from the operating system itself, which can better protect the system startup. Even if the system needs to be reconfigured due to a startup error, parents can simply reconfigure the startup partition.

Moreover, for systems above win8, using UEFI secure boot to create a trust source between the certificate stored in the firmware and the platform firmware can ensure that the signed and authenticated "known security" code and boot loader can be executed almost before the operating system is loaded, and can prevent users from executing malicious code at the root path.

2. Flexible startup.

EFI startup is similar to GRUB startup. At startup, you can call EFIShell, where you can load the specified hardware driver and select the startup file. For example, if the default startup fails, load the startup file on the U disk in the EFIShell and continue to start the system.

3. Support ability is greater.

Due to the limitation of MBR, the traditional BIOS startup cannot start the hard disk above 2. 1TB by default. With the continuous decline of hard disk price, hard disks with the size of 2. 1TB will gradually become popular, so UEFI startup is also called an increasingly mainstream startup mode.
