The Parallels Image Tool can create images of real hard disks. Such disks are intended mainly for migrating data from your real computer to a Virtual Machine. Since configuration of the Virtual Machine is probably different from the hardware configuration of your real computer, an operating system installed on the real disk (if it is installed) is not likely to function properly on the Virtual Machine. Thus such virtual disk is not recommended to serve as startup disk, rather it should be attached to an existing configuration as an additional one.
An image of a real hard disk is created in plain format only. See the Format of The Virtual Disk in the Hard Disk Images topic for description of the plain format.
Virtual hard disk in plain format occupies all its size right from the moment it is created. This means that the disk image is the same size as the real disk itself, regardless of how much space on the real disk is actually used. So, to create an image of a real hard disk you should have one real hard disk more for storing the image file. And to accommodate the image, the size of the additional hard disk should be not less than the size of the one you made a copy of.
Note: In order to create an image of a real hard disk you should have an additional hard disk connected to your computer for storing image of the first one. Additional disk should be at least 5% larger than the first one.
To create an image of a real hard disk:



in the Source field select physical hard disk to be duplicated,
in the Destination field specify destination directory and file name for the disk image file that should be located on another physical hard disk.
