New Build Problem, Pressed Wrong Button on First Menu

[Unknown12]

Hello,

I had built a new PC and when I turned it on the screen said,

"CPU or Memory Changed ! ! ! Please enter setup to configure your system.
Press F1 to run system.
Press F2 to load default values and continue.

I meant to press F1 but (I don't know how but I) pressed F2 on accident. Is there any way to go back to that menu so that I can press F1 instead? I tried to figure it out but I couldn't because I am very new to building PCs.

Forgive me if this is simpler than I think it is, I'm not very experienced in PC building.

Thank you in advance.

EDIT: When I pressed F2 it said,

"Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press a key"

UPDATE: I fixed it. It was just ready to install the OS. There was no problem but thanks for the help anyways.

If you unplug the PC, and restart it you should be able to get a redo on this.

It didn't work. I should also include that when I pressed F2 it said

"Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press a key"

So, that message indicates that you have no boot drive.

What are the specs of your system? Do you have a hard drive or SSD installed, and is it configured as the boot drive?
