Run a Windows Virtual Machine on Mac OS X 10.8 with a real Hard Drive partition I have dual-boot setup on my MacBook using bootcamp.  I have 2 partitions: 1 is Windows 7 and the other is Mac OS X 10.8.  I have all of my stuff personal stuff setup for the Mac side.  I have programming things that are only compatible with Windows.  I want to make it so I can do things on my Mac computer and have a way to switch to the Windows side without quitting running applications (and being able to switch back)

I would prefer if the software is free, but if you can assure me that it will work flawlessly, I will be willing to pay for software to make this work.
Both the paid virtualization apps, VMWare Fusion and Parallels Desktop for Mac, allow you to boot the Windows partition from within OS X. You could also do this manually with the free Virtualbox solution, but it's a bit tedious and I'm not sure if it works reliably.

For instructions on VMWare Fusion and Parallels, see the below, respectively:
