Windows 10: UEFI vs BIOS

    UEFI vs BIOS


    My computer has UEFI installed but when I go to the BIOS I see an old fashioned BIOS. I thought UEFI was supposed to replace the BIOS. Can someone explain?

    Some machines still keep an interface similar to what a regular BIOS looks like but still are an UEFI underneath. My Toshiba Satelite purchased in 2013 was like this. I assume it is done to help keep users from being confused by a new UEFI interface. Dont quote me on this, but I seem to think I have seen at least one with the option to switch between a classic BIOS like interface, and the new, more extensive UEFI interface. Your computer still has a UEFI like it should, the manufacturer just chose to keep a BIOS like interface to keep ease of use.

    Also yours may be like mine where you can use BIOS or UEFI. You have to tell the motherboard to use one or the other.

    That does not change the firmware that loads when you enter UEFI setup. That only changes the mode in which the computer boots the hard drive/SSD. UEFI requires a FAT32 EFI System partition to boot from. Legacy BIOS mode (also called CSM) boots the computer from either a System Reserved partition or other partition marked as Active that contains the proper boot files for BIOS booting. The active partition for legacy BIOS booting can be either FAT32 or NTFS.

    My ASUS laptop is UEFI but the BIOS GUI looks no different than any other PC BIOS I've seen. Other than a few extra settings.

    I think OEM manufacturers still retained old fashion way of Bios on top of UEFI. So you may see nothing fancy unless you are build a custom pc.
