BIOS+MBR and UEFI+GPT boot modes support the installed versions of windows systems.

The startup mode of operating system is divided into UEFI and Legacy. Traditional startup mode LegacyBIOS needs self-check when it is turned on, and the startup process is complicated. UEFI startup mode directly loads the operating system from the pre-boot operating environment, which simplifies the startup process and effectively improves the startup speed.

At present, there are two main boot modes: Legacy+MBR and UEFI+GPT. MBR and GPT are partition table formats of hard disks. Look at the difference between MBR and GPT formats. Because BIOS can't recognize GPT partition, GPT disk can't be used to install operating system under traditional BIOS, but can only be used for data storage. UEFI can recognize both MBR and GPT. Both MBR and GPT support the installation of operating system in UEFI mode, but Microsoft stipulates that only GPT hard disk can be used to install Windows in UEFI mode. Next, let's learn about the Windows system that Legacy+MBR and UEFI+GPT can install with Bian Xiao.

First, the compatibility analysis of different versions of Windows system to GPT disk;

GPT partition table disk does not support 32-bit win7 and system versions before win7, but supports 64-bit XP, win7, win8, win 10 and 32-bit win8, win 10. Generally, GPT disks are more combined with 64-bit windows systems.

Support GPT hard disk to install 32-bit Windows system.

Support GPT hard disk to install 64-bit Windows system.

Second, LegacyBIOS+MBR and UEFI+GPT support the installed Windows system.

Traditional LegacyBIOS+MBR supports the installation of all Windows systems. UEFI+GPT can't install 32-bit systems such as win7 and various 32-bit systems before win7, but supports the installation of 64-bit win7, win8, win8. 1, win8.10 and win8. 1 0. Xpx64 can only support IA64 Itanium processor based on x64 for GPT installation, while CPU based on AMDx64/IAx86 architecture cannot be used for GPT installation.

The above is the introduction of windows system versions supported by traditional LegacyBIOS+MBR and UEFI+GPT startup modes. After reading this introduction, I believe you have a certain understanding of the startup mode of the system.
