Can I copy from VHD to physical disk to replace my host OS? [duplicate]

I am planning to upgrade from a 32 bit os (Vista) to 64 bit (7). As there is no straight upgrade path, and I do not want to spend an entire weekend setting everything up with no immediate rollback (apart from an image), is there a way I can make a virtual disk with Windows 7 and then copy this to the physical hard drive and override my host OS (Vista)?
