I am preparing for the Customer Preview for Windows 8 and I would like to have both Windows 7 and Windows 8 on my computer (dual booting).

However, I Don't want to lose my current data on Windows 7. Is there a tool where I can create a new partition for Windows 8 (customer preview) but also keep my current Windows 7 install?

Free is best but if I have to do a paid app then I will.

Windows 7 has this ability built in. You can shrink your current volume and then create a new volume in the unused space.

An option to run both Windows 8 and Windows 7 is to boot to VHD. This will let you choose to boot into either Windows 8 or Windows 7 and you won't have to worry about partitions.

The performance hit for virtualizing the hard disk is minimal. Everything else runs on bare metal.
