I have only ubuntu-gnome 14.04 on my laptop when i am booting into my system some times only show's the grub. Any way I don't need the grub any more but, if I have to get into generic mode to reset my password then what should I do
GRUB_DEFAULT=0
GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=lsb_release -i -s 2> /dev/null || echo Debian
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX=""
00:02.0 VGA compatible controller [0300]: Intel Corporation 3rd Gen Core processor Graphics Controller [8086:0166] (rev 09)
Subsystem: Dell Device [1028:0597]
Kernel driver in use: i915
uncomment this line from your grub file:
GRUB_HIDDEN_TIMEOUT=0
then change your:
GRUB_TIMEOUT=10
to:
GRUB_TIMEOUT=0
after:
P.S.
You can backup your old settings from current grub file in case you will change your mind and want to use it again.
