Ubuntu 16.04 LTS and GRUB2 - Ask Ubuntu


my grub2 ver 2.02~beta2-36ubuntu3.4 not automatically boot ubuntu. keeps coming grub os boot selection screen although have 1 os listed. have tried number of resolutions on own , cannot boot ubuntu directly. have tried modifying values in /boot/default/grub.cfg file following set follows:

# if change file, run 'update-grub' afterwards update # /boot/grub/grub.cfg. # full documentation of options in file, see: #   info -f grub -n 'simple configuration'  grub_default="saved" grub_saveddefault=true grub_hidden_timeout="3" grub_hidden_timeout_quiet="false" grub_timeout="0" grub_distributor="`lsb_release -i -s 2> /dev/null || echo debian`" grub_cmdline_linux_default="quiet splash" grub_cmdline_linux="" #grub_background="/boot/grub/kali.png"  # uncomment enable badram filtering, modify suit needs # works linux (no patch required) , kernel obtains # memory map information grub (gnu mach, kernel of freebsd ...) #grub_badram="0x01234567,0xfefefefe,0x89abcdef,0xefefefef"  # uncomment disable graphical terminal (grub-pc only) #grub_terminal="console"  # resolution used on graphical terminal # note can use modes graphic card supports via vbe # can see them in real grub command `vbeinfo' #grub_gfxmode="640x480"  # uncomment if don't want grub pass "root=uuid=xxx" parameter linux #grub_disable_linux_uuid="true"  # uncomment disable generation of recovery mode menu entries #grub_disable_recovery="true"  # uncomment beep @ grub start #grub_init_tune="480 440 1"  export grub_menu_picture="/boot/grub/kali.png" grub_disable_os_prober="true"

why complicate matters? go simple grub config. 

grub_default=0 grub_hidden_timeout_quiet=true grub_timeout=10 grub_distributor=`lsb_release -i -s 2> /dev/null || echo debian` grub_cmdline_linux_default="" grub_cmdline_linux=""
