来源：互联网发布：成都锐理数据编辑：程序博客网时间：2024/06/14 09:22

打开/boot/grub/grub.conf文件，修改其中的default的值即可。

当default=0时默认启动CentOS (2.6.32-279.el6.x86_64)
当default=1时默认启动Win7

# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You do not have a /boot partition. This means that
#          all kernel and initrd paths are relative to /, eg.
#          root (hd0,6)
#          kernel /boot/vmlinuz-version ro root=/dev/sdb7
#          initrd /boot/initrd-[generic-]version.img
#boot=/dev/sdb
