    Can’t boot in Uefi mode


    I just built a new pc and everything works great, as long as I select CSM in the bios. However, if I try to boot with UEFI, it boots straight to the bios. I have windows 10 pro installed on a sata ssd. Any suggestions?

    UEFI vs Legacy boot mode

    Yep, UEFI mode with Win 10 loading I get the Asus logo.

    IIRC there maybe an option within motherboard UEFI to disable the Asus logo but not looked into it. On another forum I have read that what logo you get at Win 10 loading is the easiest way to know what bios mode OS is in.

    If system is booting in legacy mode - you get Windows Logo.
    If system is booting in UEFI mode - you get OEM logo.

    Above also applies to Win 8 but not Win 7.

    Can't disable UEFI boot on HP 250 G3

    I got it, I was not accustomed to UEFI (because on HP 4540s I disabled it) and I automatically thought that if I boot from the first menu it will boot in UEFI mode, but I have to go to second menu "Boot From EFI File" to get a list of EFI boot options:

    I installed Ubuntu Mate and Windows 8.1 from the first menu (the picture) and they both installed in BIOS mode. Quite simple really.

    Can’t boot in Uefi mode

    Failing to install Windows 10 in UEFI boot mode

    Hi

    I’ve been reading articles in this community and others the last couple of days and I’m getting more and more confused.

    I have made my first build with the following equipment:

    Asus Prime Z370-P (Bios version 1002x64, firmware 11.8.50.3470)

    Intel Core i5 8400 2,8GHz

    Samsung 860 EVO Series MZ-76E250B 250GB

    and other..

    I purchased a Windows 10 Home Eng Retail licence on USB directly from Microsoft.

    When installing Win 10 it always ends up being installed in Legacy BIOS mode.

    First time, I only followed the instructions on screed and had a successful installation, but in Legacy Bios mode.

    The second time I made the following change the UEFI:

    Boot\Secure boot\OS type = Windows UEFI mode

    Installation was still being made in Legacy Bios mode.

    Third time

    Boot\Secure boot\OS type = Windows UEFI mode

    When Win 10 installation started I entered the cmd prompt and made the following commands in order to change to gpt

    Diskpart

    List disk

    Select disk 0

    convert gpt

    Exit

    I then continued with Windows installation which still ended up in Legacy Bios mode.

    I’m getting crazy and I don’t know what I’m going to do : (

    What do I need to change in the UEFI?

    What do I need to do to prepare the disk for UEFI mode?

    Is my purchased Windows 10 USB key prepared for UEFI mode?

    Can someone describe, step by step what I need to do?
