what is windows uefi mode

#UEFI is mainly a standard that describes type interfaces in detail. This type of interface is used as the operating system to automatically load the Windows operating system from the pre-boot operating environment. Simply put, UEFI boot mode is a new version of boot initialization annotation settings.

So, what are the advantages of using UEFI mode to start Windows systems?UEFI provides larger disk capacity

Because the traditional MBR partition can support up to 2.2TB hard disk and 4 primary partitions, while the GPT partition format in UEFI mode can support hundreds of TB size hard drive and 100 primary partitions, which is especially useful for users who use Windows operating system.On the other hand, with the efforts of various manufacturers (ASUS, Gigabyte, Seagate, etc.), the traditional MBR partition of 32-bit systems can also use hard drives of more than 2TB through "virtual disks" and the like. , but that is of course not as labor-saving and worry-free as the native support of UEFI GPT.

2. UEFI provides higher performance


Since the traditional BIOS is specially customized for traditional 16-bit processors, it is relatively The addressing ability is particularly low and the performance is very poor. On the contrary, UEFI can be applied to any 64-bit processor. The addressing ability is also very powerful and the performance is excellent. To put it bluntly, it can load more hardware. This will allow you to boot into Windows more quickly.

3. 64-bit new systems have advantages


Generally speaking, uefi only supports 64-bit systems, starting with Windows Vista SP1 and Windows Server Starting in 2003, all 64-bit systems can provide UEFI boot support, while xp systems and 32-bit systems can only be booted through UEFI compatible modules.

4. More convenient batch installation


Motherboards equipped with UEFI can be installed "broadcast" through the network, and one image is broadcast to Installing the operating system on multiple computers at the same time will be more convenient for some users in the enterprise.

5. Faster boot and hibernation recovery


Traditional BIOS uses Int 13 interrupt to read the disk, and can only read 64KB each time. Very inefficient, while UEFI can read 1MB each time and load faster. In addition, Microsoft's WIN8/WIN10 operating system has further optimized UEFI support, which can achieve fast startup and quick boot.

6. Safer startup


In addition, there are rumors that Microsoft’s WIN8/WIN10 operating system uses UEFI to limit the survival of Linux and other systems , in essence, this design is to prevent users from running unauthorized code and ensure better security. If you feel that you do not need this feature of safe startup, you can choose to turn off this feature.
