Hi

I presume you are reading the message provided from POST (Power On Self Test)
There you can see different messages.

As far as I know pressing F12 at the beginning of the boot process will enable the boot menu. Then you can choose between different boot options and boot devices;

So don’t worry, it’s nothing unusual.
I think it should be possible to disable this in the BIOS;
Check the option for Boot Settings Configuration / Quiet Boot -> Disabled or something like this.
Cannot remember exactly how the option is called.

greetings
