I've installed a new SSD into a laptop of mine, and I need to install Windows 10 on it. I have anEUFI firmware (not classic BIOS nor enabled CSM), but it will not recognize the boot media. Every time I hit "Add Boot Option" I get "File System Not Found".
I have confirmed the boot media is UEFI capable and working – I used it yesterday on another machine successfully in UEFI mode AFTER I saw the issue on this one. The boot media is on an external USB BluRay player. I confirmed the firmwareis set to normal UEFI and USB support is enabled. The BluRay player is visible when an OS is installed, so the USB ports are working. I have updated the firmware to the latest version. I have removed the CMOS battery to try and drain/reset the BIOS. Nothing has changed though – I still cant select a boot device.
Is there some way to reset the UEFI so it can detect the USB media?

It will not allow non-OEM installations likely. Try disabling
Secure Bootand enablingLegacy Supportin BIOS. This will allow installations from most media devices.
