本文档介绍了如何在Centos 6环境下制作一个包含grub 0.97的U盘启动盘。首先确保U盘有一个MBR和boot分区，如sdb1。然后通过两个步骤完成：1. 将grub写入U盘；2. 从grub4dos官网下载grub.exe并存入U盘boot分区。参考链接包括grub 0.97官方文档和grub4dos使用指南。

前提：

U盘:需要MBR和至少一个分区，假设u盘boot分区为sdb1

操作系统:Centos 6

#写入bootsector
[root@localhost ~]# grub-install --root-directory=/mnt/extend/usbdisk /dev/sdb1

Installation finished. No error reported.
This is the contents of the device map /mnt/extend/usbdisk/boot/grub/device.map.
Check if this is correct or not. If any of the lines is incorrect,
fix it and re-run the script `grub-install'.

(hd0)	/dev/sda
(hd1)	/dev/sdb

#写入MBR
