Software to backup data and files on a Windows computer
How can I back up the entire Windows 7 installation to be used on another drive as if it were a new operating system?
For example, I'd like to use both Ubuntu and Windows 7, yet have an entire Ubuntu partition on the computer and Windows on a separate drive. But the OS backup would absolutely need to be like exactly the same version as before when first used.
Is there some way to do this?
