How does Win10 determine the type of Windows startup?

During the process of installing the system, we often need to judge the startup mode of Windows. Normally, the Windows startup mode is divided into UEFI and BIOS. How to determine the type of Windows startup? The following small series to share with you the four methods of determining the Windows startup type under the Win10 system.

First, the most installed X method:

When installing the operating system, the installer will collect some necessary information, the computer startup method is one of them. Find the setupact.log file in your computer's C:\\Windows\\Panther folder, open it with Notepad, and search for Detected Boot Environment, where you can see how the system boots.

Second, the most intelligent method:

If you know the relationship between GPT and UEFI boot, then you probably know, Windows wants to boot from a GPT hard disk, it must be UEFI The mode is started (the reverse is not true). Look at the hard disk type in the disk management, if it is GPT, then the computer must be UEFI boot. Open disk management, right click on the main hard disk, if it appears "converted to GPT disk", then the hard disk is MBR type; if it appears "converted to MBR disk", the hard disk is GPT type (because it is the main Hard disk, this item is gray unavailable state).

Third, the expert use this method:

Note: This method is suitable for Win8 and later systems.

Press Win+R to open the run, enter msinfo32, and press Enter to view the system information. In the BIOS mode, if "Traditional" is displayed, it means that the system startup mode is Legacy BIOS; if it is UEFI, UEFI is displayed.

Fourth, the way you think of:

system startup files between the two methods is not the same, under the traditional mode startup file is exe program, and the next UEFI mode The startup file is the efi program. If you have Rubik's Cube installed (click here to download), open “software setup master”——“system settings”——“multiple system settings" in the boot menu you will see Go to the full path to the startup file and see the end of the file.
