There is currently no line option to remove this entry from the menu. The display of memtest86+ can be inhibited by removing the executable bit from this file and running sudo update-grub. </quote> </blockquote></div> Removing only the executable bit makes recovery mode still in the system but that option would not be highlighted in the display. Is it like that? It's a better option then.
