Does win7 support uefi startup?

win7 supports uefi startup, but it needs to be a 64-bit system to be compatible with startup, and the hard disk must be in GPT format; UEFI does not support 32-bit systems.

UEFI startup is not supported in WIN7 32-bit. It can only be compatible with startup in 64-bit, and the hard disk must be in GPT format. .

1. Installation requirements: BIOS must start the computer in UEFI mode. Remember! Many people die at this step. If you start the installation program as before, an error message will appear stating that it cannot be installed to the GPT partition, causing the installation to fail.

2. Installation media: CD, U disk, mobile hard disk.

① CD: Just pay attention to one thing, start the computer in UEFI mode.

②U disk, mobile hard disk: The partition where the installation file is stored must be a FAT or FAT32 partition, not an NTFS partition. Because UEFI does not recognize NTFS partitions.

③ If it is installed from a USB disk or a mobile hard disk, you need to add UEFI support files, otherwise it cannot be started in UEFI mode.

Then let’s take a look at the benefits of turning on UEFI mode

1. UEFI provides larger disk capacity

The maximum traditional MBR partition is only It can support 2.2TB hard disk and 4 primary partitions, and the GPT partition format, one of the UEFI specifications, can support over 100TB of hard disk and 100 primary partitions, which is especially useful for users using Win7.

2. UEFI provides higher performance

Traditional BIOS is specially customized for traditional 16-bit processors, with low addressing capabilities and poor performance; while UEFI can be applied to any 64-bit processor The processor has much stronger addressing capabilities and excellent performance - to put it bluntly, it loads more hardware and boots to Windows faster.

3. 64-bit new systems have advantages

As long as the 64-bit system can provide UEFI startup support, XP systems and 32-bit new systems can only use UEFI compatible models. The group starts up.

4. More convenient batch installation

Motherboards equipped with UEFI can be installed "broadcast" through the network. One image is broadcast to multiple machines to install the operating system together, which is good for enterprise users. It's especially convenient.

5. Faster boot and hibernation recovery

Traditional BIOS uses Int 13 interrupt to read the disk, which can only read 64KB each time, which is very inefficient, while UEFI can read 1MB each time. Loads faster.

6. Safer startup

To ensure better security, users can choose to turn off this function if they feel it is not needed.
