?minimal BASH like line editing is supported?

I encountered this Grub error while booting Kali installer (by usb), i?ve tried to fix the error with a live version, but as before, when It boots the usb it shows the same error. I?ve tried with ?normal? command that shows the OSs to boot (kali linux; kali linux (forences) and anothers similars) but newly don?t boot showing ?linux is not a recognized command?
