1.进入目录：[root@RHCE grub]# cd /boot/grub/
2.更改文件grub.conf
vim grub.conf
# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE:  You have a /boot partition.  This means that
#       all kernel and initrd paths are relative to /boot/, eg.
#       root (hd0,0)
#       kernel /vmlinuz-version ro root=/dev/sda2
#       initrd /initrd-version.img
#boot=/dev/sda
default=1----------默认从0开始，1，2以此类推！如为0，就为选择第一个；1就为选择第二个。timeout=5---------等待时间。
