Program after grub during iso USB installation?

I'm unable to get Fedora to boot since a new BIOS update. When trying to install, I get the Grub options - fedora, troubleshooting, etc. then when I select fedora install, it goes to a no blinking cursor.

Is this still part of grub that is not working, or is it another program that is failing to boot? In either case, is there any way to say sub in another distros equivalent program or something?
