Transitioning to UEFI for Windows 11 Installation

[werkgevert7]

I've switched my drive and BIOS settings to UEFI to prepare for Windows 11 installation. However, upon restarting, I encounter the message "Select proper boot device and press any key." I've attempted reverting the BIOS settings back to legacy/disabled, but the issue persists. I've also tried using BIOS defaults and utilized Disk Genius to convert to GPT. How can I resolve this?

What kind of medium are you trying to install from?? It looks to me as if your installation
medium is not bootable or at least not recognized by your computer. If you want to install
on a GPT (UEFI) drive, your boot medium must be UEFI as well (BIOS must be set to UEFI).
Since I do not know what computer you have, this is all the information I can give you
