I have grub2 working on my Centos7 system but the graphic characters which draw a box around the menu options are missing, and so is any text at the top/title bar.I've tried changing color_normal color_highlight menu_color_normal menu_color_highlight and they affect text on screen, but the line drawing characters never appear.My /etc/default/grub contains:GRUB_FONT=/boot/grub2/unicode.pf2GRUB_TIMEOUT=20GRUB_DEFAULT=savedGRUB_DISABLE_SUBMENU=falseGRUB_CMDLINE_LINUX=crashkernel=auto rhgb quietGRUB_DISABLE_RECOVERY=trueGRUB_GFXMODE=autoGRUB_BACKGROUND=/boot/grub2/logo2.pngmenu_color_normal=yellow/blackmenu_color_highlight=black/yellowcolor_normal=white/blackcolor_highlight=black/red
