Choose uefi or legacy when booting from USB disk
Nowadays, new computers use uefi gpt boot mode to adapt to new operating systems such as win8 and win10. However, most systems before win7 do not support uefi, but use legacy boot mode. The hard disk partition table is mbr. instead of gpt.
The operating environment of this tutorial: Windows 7 system, Dell G3 computer.
This depends on which computer system is used. If you install win7 64, please select legacy only or old version first, and check if there is a secure boot option in the bios. If so, set it to disable.
Because now new computers use uefi gpt boot mode to adapt to new operating systems such as win8 and win10. However, most systems before win7 do not support uefi, but use legacy boot mode. The hard disk partition table is mbr , instead of gpt. If you want to install a system before win7 on a new model, you must change uefi to legacy, and then change the hard disk partition table gpt to mbr.
Extended information:
The difference between Legacy UEFI mode and UEFI mode:
1. Legacy UEFI boot mode is based on certain computer hardware devices and The operating system (such as WinXP/7) does not yet support UEFI BIOS-based situations. Consider starting from the traditional BIOS boot mode. Legacy BIOS boot mode allows HBA, module devices to use Rom options.
2. The UEFI boot mode is used for the operating system to automatically load from the pre-boot operating environment to an operating system, thereby simplifying the boot process and saving time. It also supports hard drives above 2T and strengthens hardware support. The reason why Win8 starts quickly is related to Win8’s native support for UEFI mode.

What does legacy and uefi startup mean?
Mar 10, 2023 pm 06:21 PM
Legacy boot refers to the boot method before BIOS. It is the traditional BIOS boot mode and is interdependent with the MBR partition mode. It can install the MBR partition system and supports the installation of all Win systems. It has strong compatibility; however, the MBR partition cannot support more than 2T hard drive and low efficiency. uefi boot refers to the boot method after BIOS. It is a new boot mode. It supports GPT partition structure and must be in GPT partition table format to boot; it can speed up the startup speed and improve the startup speed of the operating system after booting.

Jan 01, 2024 am 10:38 AM
Some older motherboards do not support uefi startup, but the automatic update and upgrade of win11 system requires uefi startup, so you cannot directly upgrade win11 during the system update. But this does not mean that we really cannot install win11. We can still use the pe system to install it. Let’s take a look at it together. How to install win111 if the motherboard does not support uefi? If the motherboard does not support uefi, you can use the pe system to install it, because the pe system installation can ignore almost all installation conditions. 2. First, you need to download a win11 image system file. 3. Then download a Youqitong software to help us quickly enter the pe system. 4. After the preparation work is completed, open Uqitong.

With the continuous updating of win10 system, its original installation image is getting larger and larger, which brings troubles to students who like to use U disk for UEFI boot method installation. As we all know, using EFI method to install the system directly installs the original Microsoft image. After decompressing, copy to the root directory of the U disk in fat32 or fat16 format, and then directly set the motherboard U disk to start the installation. However, many friends have reported that it backfired recently. There is a restriction on using the U disk in fat format, that is, a single file. The maximum cannot exceed 4G, otherwise it will be impossible to write. However, as the win10 image increases, the install.wim file in the installation package becomes larger and larger, exceeding 4G, which makes it impossible to directly use
