XP与Centos Linux双系统 默认启动顺序解决方案.doc

XP与Centos 双系统默认启动顺序解决方案情况一：默认Centos启动，要改为XP启动1、进入Centos系统，寻找系统启动文件，然后使用vi 或 gedit 等指令打开配置文件进行更改。2、配置文件位置：/etc/grub.conf 或 /boot/grub/grub.conf 3、配置文件内容#以下为配置文件内容 # grub.conf generated by anaconda# Note that you do not have to rerun grub after making changes to this file# NOTICE: You do not have a /boot partition.
