I am using FreeBSD 11.3-STABLE for pfSense. In the process of restoring an old backup for pfSense, everything got trashed on the computer. So, now, when I boot up the computer, I get "no boot loader (see attached photo)." I put in the default and nothing happens. I tried to reinstall from a USB drive, but that doesn't work. Being a novice at this, how can I get out of this part to a prompt to get other information to boot from the USB drive to reinstall? Thanks.
