What does uefi boot mean? What are the advantages of UEFI boot versus Bios boot
UEFI boot is a new motherboard boot option that is being seen as a successor to the BIOS that has been around for more than 20 years. As the name suggests, fast boot is to improve the startup speed of the operating system after boot. Due to the intervention of UEFI in the boot process, the way Windows 8 boots into the system will be different from the traditional boot process. After SSDS subvert the problem of slow computer boot, UEFI+Win8 is likely to subvert our concept of boot speed once again.

What does UEFI boot mean?
In popular terms, UEFI is a new motherboard boot initialization of the annotation Settings, relative to the BIOS, the previous u disk boot is for bios, can not boot uefi files on the uefi motherboard to PE, and some pe to simplify this. UEFI stands for Unified Extensible Firmware Interface (Unified Extensible Firmware Interface), which is a standard that describes interface types in detail. This interface is used to automatically load an operating system from a pre-booted operating environment to an operating system.
So today Xiaobian will simply introduce to you what are the advantages of UEFI boot mode compared with the traditional BIOS. I hope that after reading this, you will have a new understanding of UEFI startup.

UEFI boot compared to Bios boot advantages
1, stronger security
UEFI boot requires a separate partition, which isolates the system boot file from the operating system itself, which can better protect the system boot. Even if a system boot error requires reconfiguration, we can simply reconfigure the boot partition. Moreover, for win8 systems, it leverages UEFI secure boot and creates a source of trust between the certificate stored in the firmware and the platform firmware, which ensures that signed and certified "known safe" code and boot loaders can be executed near before loading the operating system, preventing users from executing malicious code in the root path.

2. More flexible startup configuration
EFI boot is similar to GRUB boot in that you can call EFIShell at boot time, where you can load the specified hardware driver and select the boot file. For example, if the default boot fails, the startup file on the EFIShell loading USB flash drive continues to boot the system.
3, the support capacity is larger
Due to the limitation of the MBR, the traditional BIOS boot cannot boot a hard disk larger than 2.1TB by default. As the price of hard disks continues to fall, hard disks above 2.1TB will gradually become popular, so UEFI boot is also the mainstream boot method in the future.
