    BIOS and UEFI issue


    I have a brand new Asus K555 laptop running core i5 5th gen. But though it is new, it seems to be running BIOS. It is old fashioned cursor less one. But it supports secure boot, GPT disk and it boots in CSM mode. So I think I can install UEFI. Please advise.
    Thank you

    Never have run into "It is old fashioned cursor less one.", can't comment on that.

    If it is using Secure Boot it most likely is UEFI. Since it is new it either is properly set up or you need to contact ASUS about getting it fixed.

    I heard UEFI has mouse support. But mine doesn't. That's what I meant with 'cursor less'. It doesn't use secure boot as of now. Once I enable it CSM gets turned off and I can't boot into win10. So I have it disabled. The laptop had come with DOS. I installed win10 on my own and then converted my hard disk into MBR for another purpose. So now I can't install easyUEFI on my system though it can on older PCs. This is what is bothering me. Please help me.

    Thank you very much

    UEFI Supports a Graphical UI with mouse, but it doesn't have to implement one. That's just an option, and depends on the OEM. It may also have a setting in the firmware to enable the UI mode.

    So you think mine is UEFI? But I can't boot win10 without CSM. So I messed up while installing win10? EasyUEFI says it can't install in non UEFI OSes.
    Please help

    Lots of bioses use a dos style text interface. You just navigate using cursor keys. You meant mouseless.

    Windows 10 can run in bios or eufi mode.

    Open up a command box with admin rights and run these two commands

    diskpart

    list disk

    and post image of results.

    Also check on system info page (control panel, system) and post image of that page as well.

    This confirms you have a legacy bios install. You need to do an EUFI install, assuming your PC is EUFI capable (most in last four years or so are). Given your pc is an i5, pretty sure it must be.

    May need to change bios settings, and create new indtallation mefia).
