由于windows 7系统启动的引导方式与xp系统不同，通过反复试验于网上搜索的多种方法，总算找到了下述办法：
在Windows7 中使用grldr + menu.lst 引导linux系统和win7
首选备份bcd(为此付出了多次重裝win7的惨痛代价…):
/createstore 创建一个新的空白启动配置数据文件。 bcdedit /createstore C
创建BCD启动配置数据文件储存到“C”文件夹。 /export 备份启动配置数据文件。 bcdedit /export “C Backup” 备份BCD启动配置文件到“C”文件夹，并以“BCD Backup”命名。 /import 还原启动配置数据文件。 bcdedit /import “C Backup” 从“C”文件夹恢复BCD启动配置文件。然后拷贝准备好的 grldr 和 menu.lst 到C 盘根目录下.
重启电脑…见到了久违的menu.lst菜单…
注: 附上自己的menu.lst菜单样本：
