Hi,

When sometimes the power fails and during restarting it didn't boots up and
stops at Grub boot loader menu. And not loading the default OS.
GRUB_DEFAULT=0Do you have any other OS installed? As a workaround, you can try setting
GRUB_HIDDEN_TIMEOUT=1
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=""
