To find out if your computer is using a BIOS or UEFI interface, navigate to the Panther folder in Windows Explorer. Both systems act as an interface between the hardware and operating system. Despite the same task, UEFI and BIOS differed in some respects.
These are the differences between UEFI and BIOS
BIOS, short for basic input output system, is the basic input and output system of a computer and has the task to make the computer operational. For this, he initializes the individual components of the PC, checks their functionality and then starts the operating system. The successor of the BIOS is the Unified Extensible Firmware Interface (UEFI), which has some new features compared to the BIOS. The UEFI works like a small operating system can be operated with the mouse and updates can be loaded and installed directly via the UEFI. In addition, only booting 64-bit systems is possible with UEFI.
UEFI or BIOS: Find out which system your computer uses
If you would like to know whether your PC is still running a BIOS or using a UEFI interface, this can be done via the Windows Explorer. Open it by pressing the key combination “Windows key” + “E”.
Navigate in the Explorer to the folder “C: \ Windows \ Panther” and open the file “setupact.log” with a double-click.
Then start the search dialog by pressing “Ctrl” + “F” and type in the term “Detected Boot Environment”. Confirm your entry with the Enter key.
In the line with the term you are looking for, you can see which interface your PC uses. This entry ends with either BIOS or EFI.
