Windows 10: Windows fails to detect UEFI BIOS, assumes Legacy instead

Hi,


Due to some string of events, my computer has quick boot enabled in BIOS. I need to load UEFI to change some things, and am unable to because this setting is enabled. I assumed there was a way to reboot into UEFI from inside Windows 10, so I looked up how and found the answer: There is an option in the "Advanced startup" menus to do this. Unfortunately, this option seems to be hidden if Windows 10 erroneously detects that you are using legacy BIOS instead of UEFI. This appears to be the case in my current install in MSINFO the BIOS Mode is set to Legacy.


My questions are:

• How do I change BIOS Mode to UEFI in my current install?
• How do I make sure this remains the case in future OS resets/reformats?
• Similarly, when building other computers in the future, how do I make sure Windows 10 does not make this same error?

My questions are not:

• How do I access my BIOS despite Windows 10 misidentifying my BIOS Mode?

Thank you for your time,

Alex

Problem Regarding Bios Change from UEFI to Legacy

I have hp pavilion p045tx with windows 10 pro. I recently install Ubuntu with windows 10 so for that I convert my bios setting from UEFI to Legacy mode for install third party software like wireless Driver and all in Ubuntu.
But after every restart the bios setting change to default and that is to UEFI mode and that will cause an problem of no OS detect. Every time I have to go to bios setting and enable the legacy mode to start my OS. Can anyone suggest me what to do in this
case.

 

UEFI / Legacy BIOS Mess and Windows Update

@NavyLCDR suggested just that, and gave instructions on how to do it using Macrium.

IMO, that is the best way forward for the OP.

 

Legacy to UEFI

I'm debating moving to UEFI form my now legacy BIOS (Award Software Int.) the mother board is a GA-Z68XP-UD3 rev1.0 on the the following link it shows a UEFI BIOS U1J )UEFI BIOS)

GA-Z68XP-UD3 (rev. 1.0) | Motherboard - GIGABYTE Global

Currently I'm running the legacy F10 BIOS. Does installing the UEFI BIOS automatically take care of everything to get to the UEFI BIOS? Installing the UEFI BIOS following the instructions using the Q-flash method GIGABYTE How to Reflash Motherboard BIOS

What's steps do I take and in what order?

Much appreciated
