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>
Can somebody help me out what I should do now, please?
