Why dualboot when you can run linux in a VM, though?

This is how I do it. I run Win7 x64 with Debian Linux running in VMWare Player. I have shared folders set up and most of my Debian home folder is symlinked to folders on my Windows drive. I use Unity so my Linux apps show up on my Windows desktop with my Win7 programs (Autohotkey hot strings work in my Linix programs this way). I drag Linux programs off the "Start Menu" VMWare Player provides in Unity mode to create shortcuts which I use in a True Launch Bar Linux menu and place in a directory that FARR searches so I can just type "konsole", "kate", "word", or whatever in FARR and start whatever software I wish whether it is Windows software or Linux software. It's very nice as for the most part Windows and Linux blend fairly seamlessly. I'd never go back to dual booting again (unless I was doing 3D graphics work on the Linux side).
