U盘启动WinPE

GRUB2->grub4dos方式

通过grub4dos提供的map功能引导WinPE.iso。 

menuentry "[iso] -- WinPE(g4d)" {
    set g4d_dir="/boot/grub4dos"
    set cfgfile="find --set-root /boot/iso/winpe.iso;map --mem /boot/iso/winpe.iso (0xff);map --hook;chainloader (0xff);boot"
    linux $g4d_dir/grub.exe --config-file=$cfgfile
}

menuentry "[iso] -- WinPE(g4d)" --class windows --class os {
    set cfgfile="map /image/winpe.iso (hd32) || map --mem /image/winpe.iso (hd32); map --hook; chainloader (hd32); rootnoverify (hd32)"
    linux16 /grub4dos/grub.exe --config-file=$cfgfile
    initrd16 /image/winpe.iso

grub2+syslinux/memdisk

首先下载最新版的Syslinux，解开压缩包，memdisk文件夹下面有一个memdisk文件（没有任何扩展名），把memdisk文件复制到U盘boot文件夹下。

GRUB2的memdisk是用来读取core.img的。和syslinux的MEMDISK完全不同……详见: http://wiki.xtronics.com/index.php/Grub2_howto

借助MEMDISK（几十KB的文件），GRUB2就能加载几乎任意的镜像文件（ISO、IMG等）了，相当于是「虚拟光驱」的作用？不过引导速度比GRUB4DOS稍微慢一点。

关键就是memdisk后面的raw参数 

menuentry 'Boot Windows 8 PE ISO'{
    set root='(hd0,msdos1)'
    echo 'Loading Memdisk...'
    # 不需要insmod memdisk，因为用的是Syslinux的MEMDISK而不是GRUB2的memdisk模块。
    #insmod memdisk
    linux16 /boot/memdisk iso raw
    echo 'Loading ISO...'
    initrd16 /boot/Win8PE.iso
}

menuentry '[iso] -- /WinPE(memdisk) ' {
    #insmod memdisk
    insmod fat
    set root='hd0,msdos1'
    linux16 /boot/memdisk iso raw
    initrd16 /winpe.iso

ntldr方式

目前网络上的WinPE到处都是，各种版本其实都差不多，主要需要如下5个文件： 

LDRXPE  NTCOM  PE  SETUPLDR.BIN  WINPE.IS_

大致过程是：LDRXPE调用NTCOM和SETUPLDR.BIN读取PE找到WINPE.IS_镜像，加载WinPE。

编译syslinux

测试编译报错，以后再来查找原因。

在boot.ini中添加grub4dos

WinXP

Win7

Windows7上使用Grub4DOS有两种方法实现（除了直接将Grub安装至MBR）：

  1. 通过创建boot.ini添加启动启动项。
  2. 通过windows 7的BOOTMGR启动管理器添加启动项。

使用bcdedit或bcdedit /enum all来查看系统中硬盘或分区的GUID 标识，例如{dc0a0dea-4a4e-11df-900b-d0c518f1f5f1}。其中{legacy}表示上一代操作系统，{current} 表示当前启动硬盘上的操作系统（Windows 7），下面均以{GUID}表示。

BCDEdit修改启动选项的常用命令格式：

命令 说明
bcdedit 或 bcdedit /enum all 查看系统中硬盘或分区的GUID 标识
bcdedit /set {GUID} Description "Windows XP Professional SP3" 修改{GUID}在启动菜单中的显示内容
bcdedit /default {GUID} 设置指定GUID上的操作系统为默认启动的系统
bcdedit /timeout 3 将默认的启动菜单显示时间更改为3秒
bcdedit /displayorder {current} {legacy} 将首先显示默认启动的Windows 7，然后再显示Windows XP，
bcdedit /delete {GUID} 删除GUID上的启动菜单
