VirtualBox: Cloning a physical drive (HDD or SSD) to VDI on Windows

Open up Partition Manager on Windows to find your "disk number"

Open up a Command Prompt and type:

VBoxManage.exe convertfromraw \\.\PhysicalDrive2 C:\output.vdi --format VDI

Replacing "2" with the drive index you want to clone and changing the output location to whereever you want.

That should be it!

Update:

VBoxManage creates a full clone, meaning the image will take up as much space as the physical drive. If you want an image based on just the content, use Disk2vhd from Microsoft
