Minimal BASH-like line editing is supported

After starting my Asus R541N I got this line

GNU GRUB version 2.02-beta3+dev105.4191f2f-8beos3.1.1

Minimal BASH-like line editing is supported. For the first word, TAB lists possiblr command completions. Anywhere else TAB lists possible device or file completions.

grub>

I found in another board that I should reboot via USB or disc with the same endless system. But I don’t have an USB or disc.

So is there any idea how I can fix this?

Thank you!!!
