Windows 10: Stuck in UEFI Bios when changing to UEFI boot mode for secure boot.

I want to upgrade to windows 11 but I do not have secure boot turned on, I go to turn it on in BIOS. To do that I have to switch to UEFI boot mode, this removes a handful of drives, I go to switch on secure boot but then I cannot exit BIOS until I switch the boot mode from UEFI. I do not know how to fix this, can someone help?

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.

 

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?

 

UEFI vs Legacy boot mode

I recommend you stick with legacy install instead to avoid any compatibility problem hardware or software. Uefi have the speed advantage for boot up but I don't find it to be a good trade-off for the compatibility problems that appeared. Secure boot for uefi is a pain if you decide to install multiple os as the other os is "locked" out. I used uefi for my previous install it is a lengthy install selecting the correct bios setting without borking the install. I'll move to uefi if I don't have a need for multiple os or legacy things. So far I seem to need it.
