  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:,  #,  # DO NOT EDIT THIS FILE,  #,  # It is automatically generated by grub-mkconfig using templates,  # from /etc/grub.d and settings from /etc/default/grub,  #,  ### BEGIN /etc/grub.d/00_header ###,  if [ -s $prefix/grubenv ];
