After upgrade from Ubuntu 11.10 to 12.04 I am unable to get Ubuntu to automatically boot. Even when I set grub.cfg as follows:
GRUB_DEFAULT=0 GRUB_HIDDEN_TIMEOUT=0 GRUB_HIDDEN_TIMEOUT_QUIET=true GRUB_TIMEOUT=2 GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` GRUB_CMDLINE_LINUX_DEFAULT="quiet" GRUB_CMDLINE_LINUX=""
when rebooting, GRUB waits on its splash screen for keypressing on selected kernel.
Please help if you have any idea. I updated a grub by
update-grub command with different timeout but it does not change.
