Migrate Windows systems to new disks through Linux systems

1. Overview

This article will show you how to copy the installed version of Windows to a new disk (the new disk is greater than or equal to the window mirror size) under the Linux system.

2. Tools to use

The LiveCD tool, which can be a CD or USB boot, requires tools DD, Fdisk, and Ntfsresize.

In this example, use the following assumption:

/DEV/SDC (New Hard drive)

/DEV/SDB (old hard Drive, installed window version data in/DEV/SDB1 partition)

= Format new Disk (/DEV/SDC) =

Using the root user, do the following partition operations

The code is as follows:

[Root@centos6 ~]# FDISK/DEV/SDC

Warning:dos-compatible mode is deprecated. It ' s strongly recommended to

Switch off "mode" (Command ' C ') and change display units to

Sectors (Command ' u ').

/DEV/SDC1 1 2088 16771828+ Linux

Before completing, we must set the boot flag and partition system ID, and the partition system ID must be windows, with an ID value of 7.

The code is as follows:

Command (M for help): A

Partition number (1-4): 1

Command (M for help): t

The partition table has been altered!

Syncing disks.

= Copy MBR =

In order for the new disk to boot, we must copy the boot code from the master Boot Record (MBR) to the new disk

The MBR is in the first sector of the disk, consisting of 3 parts:

The code is as follows:

Boot Code (446 bytes)

Partition Table (bytes)

Boot Code Signature = 55AA (2 bytes)

We just need to copy the boot code, starting with the 446 bytes. Use the DD tool to copy:

The code is as follows:

# 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)

= Copy partition =

The next task is to copy the file system from one disk to another disk. Here we use the Ntfsclone tool to copy the NTFS file system

The code is as follows:

[Root@centos6 ~]# Ntfsclone--OVERWRITE/DEV/SDC1/DEV/SDB1

< 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%)

If there is a bad sector on the source disk, you need to add the--rescue option

The code is as follows:

# Ntfsclone--rescue--OVERWRITE/DEV/SDC1/DEV/SDB1

Note: The source disk is the last parameter (/DEV/SDB1)

3. Change the partition size

In the case where the new disk is larger than the source disk, we need to change the partition size to use all the space, where we use the ntfsresize command

The code is as follows:

[Root@centos6 ~]# NTFSRESIZE/DEV/SDC1

< 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. Reboot the system with a new disk

After restarting, Windows automatically checks the file system as follows (because of the size of the partition), and automatically restarts when the check is complete to enter the Windows system.

5. Summary

Of course, the copy of this way is operated on the same server (drive unchanged), if a clean Windows naked system installed in this way to different models of the server, there will be a driver problem, how to solve, please see Let's!
