Creating a copy of a physical hard drive (HDD), including its operating system (OS), to a virtual hard drive (VHD) image
Creating a copy
of a physical hard drive (HDD), including its operating system (OS), to a
virtual hard drive (VHD) image involves several steps. You will essentially be
performing a disk cloning process that converts the contents of your physical
HDD into a virtual hard disk format. This allows you to run the OS and programs
from the virtual disk in a virtual machine (VM).
Here’s how you
can do it:
Requirements:
- A virtualization software (e.g., VMware, VirtualBox,
Hyper-V) that supports virtual hard disk (VHD or VDI) formats.
- Disk cloning software like Clonezilla, Macrium Reflect,
or Acronis True Image.
- A working physical machine
with the OS you want to copy.
- Sufficient storage space
for the virtual HDD image.
Steps to Create a Virtual HDD Image from a Physical HDD
1. Prepare the Tools
- Install a virtualization software
such as VirtualBox, VMware Workstation, or Hyper-V.
- Install a disk cloning tool like Clonezilla
(free), Macrium Reflect (free and paid), or Acronis True Image.
2. Clone the Physical HDD to an Image File
- Use your disk cloning software to
create an image of the physical HDD. The image should be stored on an
external drive or in a different partition (since it will likely be quite
large).
- Most tools will allow you to
create a disk image (e.g., .iso, .img) or clone
the entire drive sector by sector.
Example with Macrium Reflect:
- Open Macrium Reflect and select
the source disk (the physical HDD).
- Choose “Create an image of the
partition(s)” option and select a destination where you want to save the
image.
- Complete the imaging process.
3. Convert the Image to a Virtual HDD
If the cloning
software creates an image file (like .img), you can
convert it to a VHD or VDI format, which can be used by virtualization
software.
- Using VirtualBox: You can use the VBoxManage command to convert the image into
a VirtualBox-compatible virtual disk.

Copy
VBoxManage convertfromraw /path/to/image.img /path/to/vm_disk.vdi
--format VDI
- Using VMware: VMware has a tool called vCenter
Converter that can convert physical disks to virtual ones.
- Install VMware vCenter
Converter.
- Run the tool and select the
option to convert a physical machine.
- Follow the wizard to create a
virtual machine and select a destination in VMware.
4. Create a Virtual Machine and Attach the Virtual HDD
Once you have
the virtual hard disk (VHD/VDI), you need to create a virtual machine and
attach the newly created virtual disk.
- In VirtualBox:
- Open VirtualBox and create a new
virtual machine.
- When it asks for a hard disk,
select “Use an existing virtual hard disk file” and choose the .vdi file you just created.
- Proceed with the rest of the VM
setup and boot up.
- In VMware:
- Create a new virtual machine.
- When it prompts for a disk,
choose to use an existing disk and select the .vmdk or .vhd file.
- Complete the setup and start the
VM.
5. Adjust the Virtual Machine Settings
Depending on
the hardware and OS, the VM might not boot correctly right away. You may need
to make adjustments:
- Install VMware Tools or VirtualBox
Guest Additions for improved compatibility with the virtual
environment.
- If there are issues with drivers
(e.g., storage controllers), you may need to change settings for the
virtual machine's virtual hardware (e.g., IDE, SATA, etc.).
- You might also need to adjust
network or display settings for better performance.
6. Boot the Virtual Machine
Once everything
is set up, start the virtual machine. The system should boot from the virtual
disk, and you should have access to the same OS and programs you had on the
physical machine, running in a virtualized environment.
Additional Notes:
- Sysprep: Before cloning your physical
machine, it is recommended to run Sysprep (System Preparation Tool)
on Windows to generalize the OS. This removes hardware-specific
information and ensures the virtual machine can adapt to virtual hardware
without issues.
- For Windows: sysprep /oobe /generalize
/shutdown
- Performance: Virtual machines might have
lower performance compared to a physical machine, especially for
graphics-intensive applications. Ensure that you allocate sufficient
resources (RAM, CPU) to the VM.
Conclusion:
By using disk
cloning tools and virtualization software, you can successfully create a copy
of your physical HDD and boot it as a virtual machine. The key steps are
cloning the physical drive to an image, converting the image to a compatible
virtual disk format, and configuring the virtual machine to run from that disk.
