Hello! I got my new Steam Deck in the mail today. I opened it up, plugged it in, and started setting it up. I chose my language, time zone, internet. Then it got stuck on “1 second remaining” when it was installing Steam. I looked online and it said this was common and to restart and switch to a 2G network. I did that. It found an error and stopped. I switched to my phone’s hot spot. It got about 80% of the way to installing Steam and then it blacked out and went to this menu. I think it is a “Boot Menu” or something? Anyways. I can’t select anything on here. No buttons work, the D pad doesn’t work. I can hit the power button but when I turn it back on it’s still this menu. I just got this Steam Deck and have barely done anything to it. I have only tried the initial start up process. Any help would be greatly appreciated.
If nothing else fixes this. Shut down the deck, press the volume up button and the power button at the same time. You should see the BIOS. Follow these instructions to reinstalk Steam OS.
