通过Linux系统将Windows系统迁移到到新的磁盘上

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

复制代码

代码如下:

[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').

Last cylinder, +cylinders or +size{K,M,G} (1-2088, default 2088):

Command (m for help): p

255 heads, 63 sectors/track, 2088 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0xa1c3a1c3

Device Boot Start End Blocks Id System
/dev/sdc1 1 2088 16771828+ 83 Linux

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.

复制代码

代码如下:

Command (m for help): A
Partition number (1-4): 1

Command (m for help): t
Selected partition 1
Hex code (type L to list codes): 7
Changed system type of partition 1 to 7 (HPFS/NTFS)

Command (m for help): p

= 复制MBR =
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:

复制代码

代码如下:

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：

复制代码

代码如下:

# 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)

= 复制分区 =
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

复制代码

代码如下:

[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)
Scanning volume ...
100.00 percent completed
Accounting clusters ...
Space in use : 7565 MB (70.5%)

如果在源盘上有坏的扇区，则需要添加 --rescue 选项

复制代码

代码如下:

# 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

复制代码

代码如下:

[root@centos6 ~]# ntfsresize /dev/sdc1/p> p> ntfsresize v2013.1.13 (libntfs-3g)
Device name : /dev/sdc1
NTFS volume version: 3.1

Current volume size: 10725732864 bytes (10726 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
