You need to check in the BIOS to see that USB Legacy Support is enabled. Without that, the USB ports have no power until the operating system cuts in. That said, it would be a mystery if that setting had been changed since it last worked for you.

How did you make the USB stick a bootable device? If you used Rufus and added a working download of, say, a Linux or Windows system, it should have worked.

It's clear that the BIOS isn't recognising a valid bootable system on that stick and passes on to the next option.
