    EFI, UEFI, Legacy BIOS.......

    This weekend I will try to do a clean install of Win 10 again, from Win 7. Have to try som new methods to see if I can get my computer running flawlessly with Windows 10.

    I will use the clean install tutorials from this forum. I hav two options, with or without UEFI installed?

    What about this thing with EFI, UEFI, Legacy BIOS? How much impact will this have on my computer regarding a flawlessly Win 10 setup?

    I don't know anything about this, other than UEFI is the newest standard regarding BIOS.

    When I look into my boot setup, it says, 1. Boot Device - [EFI Device].
    If I open Diskmanagement, this is the picture:

    Should I use the tutorial with or without UEFI when I do a clean install?

    Your OS seems to be currently installed in Legacy Mode, that means your drive is probably formatted using a scheme called MBR. For Windows to boot in UEFI mode, it required the drive to be formatted using a different scheme called GPT.
    If you can, backup the drive and reformat it to GPT if you want UEFI.

    As far as the benefits go, Legacy is old, UEFI is new. It's faster, looks prettier while booting :P. Thats pretty much it for the average consumer.

So, basically if we have a computer that doesn't have a UEFI BIOS with Secure Boot, then we can't upgrade to Windows 10? Am I right or wrong here?
