关于手把手恢复win7系统ubuntu 12。

 随着电脑的使用率越来越高,我们有时候可能会遇到对win7系统ubuntu 12.04 xp双盘3系统grub配置进行设置,如果我们需要对win7系统ubuntu 12.04 xp双盘3系统grub配置进行设置时,要怎么处理win7系统ubuntu 12.04 xp双盘3系统grub配置呢?我们按照即在/boot/grub/grub.cfg中添加如下内容即可就搞定了;接下来给大家带来win7系统ubuntu 12.04 xp双盘3系统grub配置的详细步骤:

 盘1: ubuntu12.04 win7

盘2: xp

sudo update-grub 的结果只有win7 和 ubuntu,点击win7进入系统,看到了win7和xp,win7可以启动,但是xp不能。于是在网上搜索找到了一个别人的xp和ubuntu共存的grub文件。

发现我的少了一句话,drivemap -s (hd0) ${root},于是加上就ok了。

即在/boot/grub/grub.cfg中添加如下内容即可

menuentry "Windows xp" --class windows --class os {

insmod ntfs

set root='(hd0,1)'

search --no-floppy --fs-uuid --set=root 4C844B34844B2036

drivemap -s (hd0) ${root}

chainloader +1

}

set root=(hd0,1),代表第0块磁盘的第一个分区,其中硬盘号是从0开始,分区号是从1开始。我的xp是在第0个分区。我的xp和ubuntu不再同一个磁盘,grub中ubuntu显示在hd1所以xp必然在hd0,而系统在c:盘,所以是第一个分区

整个的grub文件如下:

# from /etc/grub.d and settings from /etc/default/grub
