1. 概述
这篇文章将告诉你如何再 linux 系统下，将 安装好的windows版本 复制到新的磁盘上（新的磁盘大于等于window镜像大小）
2. 使用到的工具
livecd 工具，可以是CD 也可以是USB启动的 ，需要有的工具 dd, fdisk, and ntfsresize.
此例子中，使用如下假设:
/dev/sdc (新硬盘)
/dev/sdb (老硬盘，安装好的window版本数据在 /dev/sdb1 分区中）
= 格式化新盘(/dev/sdc) =
使用root 用户，进行如下分区操作
[root@centos6 ~]# fdisk /dev/sdc
WARNING: DOS-compatible mode is deprecated. It's strongly recommended to
switch off the mode (command 'c') and change display units to
sectors (command 'u').

在完成之前，我们必须设置启动标志和分区系统ID，分区系统ID必须是WINDOWS的，ID值为 7.

为了让新盘能够引导, 我们必须从Master Boot Record (MBR) 复制引导代码到新的磁盘上
MBR 在磁盘的第一个扇区,由3部分组成:
Boot Code (446 bytes)
Partition Table (64 bytes)
Boot Code Signature = 55aa (2 bytes)
我们只需要复制引导代码，起始的 446 bytes. 使用dd工具来复制：
# dd if=/dev/sdb of=/dev/sdc bs=446 count=1
1+0 records in
1+0 records out
446 bytes transferred in 0.026312 seconds (16950 bytes/sec)

下一步任务就是将文件系统从一个盘复制到另一个盘上.在这里我们使用 ntfsclone 工具来复制 NTFS 文件系统
[root@centos6 ~]# ntfsclone --overwrite /dev/sdc1 /dev/sdb1</p> <p> ntfsclone v2013.1.13 (libntfs-3g)
NTFS volume version: 3.1
Cluster size : 4096 bytes
Current volume size: 10725732352 bytes (10726 MB)
Current device size: 10725732864 bytes (10726 MB)

如果在源盘上有坏的扇区，则需要添加 --rescue 选项
# ntfsclone --rescue --overwrite /dev/sdc1 /dev/sdb1
注意： 源盘 是 最后一个参数(/dev/sdb1)
3. 改变分区大小
在新盘比源盘大的情况下，我们需要改变分区大小来使用所有空间，这里我们使用 ntfsresize 命令
[root@centos6 ~]# ntfsresize /dev/sdc1</p> <p> ntfsresize v2013.1.13 (libntfs-3g)
Device name : /dev/sdc1
NTFS volume version: 3.1
Cluster size : 4096 bytes
Current volume size: 10725732864 bytes (10726 MB)
Current device size: 17174352384 bytes (17175 MB)
New volume size : 17174348288 bytes (17175 MB)

4. 使用新盘重新启动系统
重新启动后，windows 会自动检查文件系统如下（因为分区大小有所变化）,检查完成后自动重起就能进入windows系统了
5. 总结
当然这种方式的拷贝是在同一台服务器上操作的(驱动无变化),如果将一个干净的windows裸系统通过这种方式安装到不同型号的服务器上时， 就会出现驱动问题，如何解决，请看下回分解！
