ubuntu 10.04显示grub菜单
时间:2010-10-27 来源:coolper
安装ubuntu10.04后,如果机器上只有一个系统,默认grub菜单是不会显示的,如果想要显示,按如下步骤操作:
1.把/etc/default/grub文件中的GRUB_HIDDEN_TIMEOUT=0的0改为大于0的数字,比如5;
2.把/etc/grub.d/30_os-prober文件中的所有set timeout=0的0改为10,如下:
adjust_timeout () {
if [ "x${found_other_os}" = "x" ] ; then
if [ "x${GRUB_HIDDEN_TIMEOUT}" != "x" ] ; then
if [ "x${GRUB_HIDDEN_TIMEOUT_QUIET}" = "xtrue" ] ; then
verbose=
else
verbose=" --verbose"
fi
if [ "x${GRUB_HIDDEN_TIMEOUT}" = "x0" ] ; then cat <<EOF if [ \${timeout} != -1 ]; then if keystatus; then if keystatus --shift; then set timeout=-1 else set timeout=10 fi else if sleep$verbose --interruptible 3 ; then set timeout=10 fi fi fi EOF else cat << EOF if [ \${timeout} != -1 ]; then if sleep$verbose --interruptible ${GRUB_HIDDEN_TIMEOUT} ; then set timeout=10 fi fi EOF fi fi fi }
if [ "x${GRUB_HIDDEN_TIMEOUT}" = "x0" ] ; then cat <<EOF if [ \${timeout} != -1 ]; then if keystatus; then if keystatus --shift; then set timeout=-1 else set timeout=10 fi else if sleep$verbose --interruptible 3 ; then set timeout=10 fi fi fi EOF else cat << EOF if [ \${timeout} != -1 ]; then if sleep$verbose --interruptible ${GRUB_HIDDEN_TIMEOUT} ; then set timeout=10 fi fi EOF fi fi fi }
