I've attached a picture. (Hopefully)
Thanks. Yes, we can see the photos.
Unfortunately though you did not take a photo of the whole screen. In particular it would be interesting what the bottom of the screen says when you highlight one of the boot entries, because that's where they usually show the keys that you can use to alter settings, i.e. pressing F5 to disable a boot entry for example.
Can you please attach a photo of the entire screen, ideally with the "OS Boot Manager" entry being highlighted?
Also, is there any screen in the BIOS that has a setting for "Option ROMs" or "OpROMs" or something like that? If yes: Can you also post a photo of that one?
