as i got a new hard drive yesterday, i decided to try it for real instead of in a VM.
there's a handy tip in that MSDN thread linked a few posts up if you want to dual boot. rather than waste time creating a usb stick/DVD, simply mount the ISO within your current windows, make sure you have another partition/drive already formatted. don't run the installer when prompted because that only lets you upgrade. instead cancel it, and browse to x:\sources\setup.exe that starts another installer which lets you choose a partition from within windows meaning it doesn't **** up your drive letters like dual booting from a usb install does.
finally when setup is complete, you'll notice windows 8 actually fully boots before giving you the choice to boot 7 - if you pick 7 it then reboots which is very time consuming. so when in windows 8, go to the startup options (right click "computer") and set the default OS to 7. this brings backs the 7 bootloader meaning you get the choice straight after bios but you can boot either 7 or 8.
