How to clone or Image hard drives? How to migrate Windows installation and all installed applications to a new drive? Upgrading HDD to SDD?

You may be looking for Drive cloning or Imaging for creating a bootable backup of your computer’s disk drive or one or more partitions   or migrating from HDD to SDD.

Here are some tips:

  1. Download and install DriveImage XML ( It is free for Home use.
  2. DriveImage XML also supports “Raw” mode, which is basically bit-by-bit cloning/imaging, useful when you intend to conduct some Data Recovery or Forensics too.
  3. For creating a bootable backup of your drive, you just need to select “Backup”:


Note: Depending on you Windows version, you may have to run the DriveImage XML as “Run As Administrator”

  1. If your target partition size is lesser than the source partition, OR you want to recreate/resize partitions at target drive, you can use EaseUS Partition Master ( ) . It is a free disk management tool (For Home use).
  2. You may also try to migrate the newly cloned/imaged drive to another computer of similar manufacturer or hardware configuration. If you get any operating system error, you can use a bootable OS CD/DVD or create a bootable USB and try to repair the OS of the cloned/Imaged Disks.


To create a bootable Windows USB Flash Drive from ISO file of Windows, you can use Rufus ( ). Rufus also supports UEFI and  GPT.


  1. With Rufus, select FAT32 file systems, if your windows ISO file size is below 4 GB , otherwise select NTFS .
  2. Depending on you Windows version, you may have to run Rufus as “Run As Administrator”
  3. To detect portable USB Hard Drives: Click the Big White-Arrow (Format Options): and check: List Hard Drives


  1. After repairing cloned/imaged drive on new computer, if you get Windows Login screen, but nothing happens after login. i.e. Task Manager works, you are able to run new Tasks such as calculator, cmd.exe but explorer.exe does not work.


Possible Reason:  At startup Windows looks into the registry and expects installation partition that is  C: (usually) for loading OS completely, however the new cloned partition gets drive letter of the portable drive (may be H:, or I:, or  J:, …, depending upon your computer).


Solution: Change drive letter (from H:, or I:, or  J:, …) to C: :

Run regedit32.exe (Registry Editor) through Task Manager and modify following setting:

a). Go to registry key:


b). Click MountedDevices, and go to Security  > Permissions.

Verify that Administrators have full control.

Close regedt32.exe, and then run regedit.exe.

a). go to registry key:


b). Find “\DosDevices\C:”. Right-click \DosDevices\C:, and then select Rename  to rename this to an unused drive letter “\DosDevices\Y:”.

c). Find the drive letter of your cloned partition. For example “\DosDevices\I:”. Right-click \DosDevices\I:, and rename it to “\DosDevices\C:”.

d). Select \DosDevices\Y:, and then name it back to “\DosDevices\I:”.

Close regedt.exe, and then run regedit32.exe. Change the permissions back to the previous setting for Administrators.

Restart the computer. Your computer should work normally.



  1. In place of SATA interface, if you wish to boot the cloned drive over USB port (portable USB Hard Drive), you may use a good freeware application WinToUSB ( ). WinToUSB can install/clone Windows to a USB drive with BIOS and UEFI supports.


Note: If you want to install Windows onto second HDD/SSD drive without using a CD/DVD/USB drive, or clone your current Windows OS installation to a HDD/SSD drive, you can also try WinToHDD ( ).

How to play .avi or .mkv video chunks like .mkv.001, .mkv.002, .mkv.003, .mkv.00…? How to get entire movie in a single file?

 Usually Movies (Videos files) have huge sizes, so these are first splitted/divided into small chunks such as .avi.001, .avi.002, avi.00…. or .mkv.001,.mkv.002, .mkv.00…. before uploading online on a Website.

 There are two methods by which you can combine or join or merge these chunks into a single file:

 First method: there are software such as HJSplit (from, that can be used for splitting and merging.

 Second Method: if you are having Windows operating system, you can follow following simple steps  to get the single file:

 1. First, ensure that you are having all the chunk files in a single folder.

2. Open Command Prompt and navigate to the above folder using “cd” command.

3. type following command:

copy /b  movie.mkv

[where  movie.mkv.00N is the last chunk file ]

4. Wait for few minutes till it gives: “file(s) were copied successfully” message.

 Now, if your VLC Player or Winodws Media Player (with right codec installed) is playing the newly created file  movie.mkv, then you can delete the file chunks. It will save your disk space!!
