使用grub for dos来引导双系统(zz)
我用的是双硬盘，分别装xp和mandrake,以前都是在bios中设置双引导很不方便（我不想覆盖xp的mbr）.自从找到grub for
dos后引导双系统真是太方便了。下载：Grub_for_dos-0.2.0pre12.tar.gz文件，解压后把 grub 和 GRLDR
两个文件拷贝到 c: 盘的根下。在boot.ini中增加一行：c:\GRLDR＝“start
grub”.重启后选择此项，它会自动搜索boot/grub/menu.lst文件，以后就像是在linux下一样。压缩包中自带boot/grub
/menu.lst文件，可以把它也放在c: 盘的根下，这样就会自动加载。不过要根据自己的情况加以修改。以下是我的menu.lst文件。

Even if you are using(in MBR)an MS-compatible boot loader such as LILO and GRUB, you may encounter problems like hard-disk-boot-failure when you move or delete the /boot/grub/stage2 file, or even when disk defragmentation operations are made.
