With Windows 7, you now have the option to boot the OS from a VHD, a virtual disk file, instead of a partition. This way, you don’t have to reconfigure your hard drive partitions.
This feature is similar to Ubuntu’s Wubi installer which uses a similar concept to avoid reconfiguring hard drive partitions.
Basically, instead of installing windows 7 to your physical HDD by getting rid of Vista or even dual booting off another partition, you can install to a virtual HDD (in VHD format), and boot off the VHD so you actually get the hardware functionality to play with!!
