The partition table on the USB key is GPT and the bios is set to Legacy boot so it cannot boot the USB key, make sure that you have UEFI enabled in the BIOS
Try a different USB key or a different port
Try a different application for making the USB installer (Ventoy, Rufus, Fedora Media Writer) some of them work better or worse on some BIOSs
Try turn off the machine (unplug it if it's a desktop) and then try again. Sometimes that helps
