Is it necessary to start uefi?

What is UEFI?

As we all know, 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. (Recommended learning: phpstorm)

What are the advantages of using UEFI mode to start Windows systems?

1. UEFI provides greater Disk capacity

Because the traditional MBR partition can support up to 2.2TB hard disk and 4 primary partitions, the GPT partition format in UEFI mode can support 100TB hard disk and 100 primary partitions. Partition, which is especially useful for users who use Windows operating systems.

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, the relative addressing capabilities are particularly low. , the performance is very poor, on the contrary, UEFI can be applied to any 64-bit processor, the addressing capability is also very powerful, and the performance is also very good. To put it bluntly, it can start faster when loading more hardware. Enter Windows.

3. 64-bit new systems have advantages

Generally speaking, uefi only supports 64-bit systems, starting from Windows Vista SP1 and Windows Server 2003, so as long as 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 perform "broadcast" installation through the network, and one image is broadcast to multiple machines for simultaneous installation operations. The system 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, which can only read 64KB at a time, which is very inefficient, and UEFI You 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. More secure 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 It is to prevent users from running unauthorized code and ensure better security. If you feel that you do not need to start this function safely, you can choose to turn off this function
