今天学习用grub4dos制作U盘启动盘，启动包括linux、windows、MSDOS、内核模块的Linux等，可以看下我的menu.lst内容就知道了，学习过的文件和样例都在附件
下图是U盘的内容：
有兴趣的朋友可以看下我的附件，里面会有你想要的文档。
本来想写得详细点，太懒了，呵呵
windows的启动引导：
1、 不修改MBR
NT loader-->ntldr -->boot.ini --> grldr -->menu.lst
一般用作“一键还原”，也可启动linux
2、 修改MBR
用bootice \bootlace\bootsect等工具写入MBR。
grub stage2 -->grldr -- > menu.lst --> ntldr/bootmgr -->boot.ini/BCD
启动的东西就多了，有兴趣看附件，里面有未加工的资料。
这是我的centos x86_64 和win 8 的linux grub启动conf文件（没有LV
M）

这是的笔记本的OEL6和xp（oel6位LVM）
