Hello, i need some help with my UEFI/BIOS startup, since i've made a bios update a few months ago i couldn't start my pc in UEFI mode (stuck on system loading with the Obsidian logo) and can only access windows when i disable it. Eeven if try to start from a bootable USB i can't get past that same screen. i even tried to convert my SSD from MBR to GBT but i still have the same problem.. i tried disabling secure boot but then again no boot but this time i've noticed something new when booting from a bootable USB. I will attach a picture and a video to this topic, but it's always the same thing. I can't get past that system loading screen with the obsidian logo. and even if i try my default settings on the BIOS, i can't find my SSD or HDD, only the bootable USB (MBR or GPT compatible) is visible.
I really want the UEFI boot back, since it's quicker, and more secure and can support larger hard drives.

If your Windows install was done with UEFI disabled then you can only boot it with UEFI disabled.
To boot another UEFI device like a USB pen, create something with UEFI boot, a windows install media for example:
Use this tool: https://www.microsoft.com/en-us/software-download/windows10
Enable UEFI and try to boot from that USB pen.

Please try it with the tool i linked. Just to make sure.

If there is a BIOS update available then you should do it! Test it again after the update.
