MacBook Pro (Summer 2010 Model, Basic Model)

I currently have OS X Lion and Windows 7 running side by side on my MacBook Pro. However I have a need to get Windows 8 running as well in this mix (a Virtual Machine is not good enough, I need the performance).

I have created a suitably sized parition (80GB) that is recognizable in Boot Camp. However every time I try to boot from the USB stick (that worked to install Windows 8 on my PC) using the latest version of rEFIt, it just boots Windows 7 and not the Windows 8 installer.

I cannot start the installation within Windows 7 as it will just install over Windows 7.

I'm guessing the Boot Camp emulation is doing something werid to stop the "Press any key to install Windows..." message from appearing (which should happen if the installer detects Windows is already installed (e.g. if you left your install disk in).

Is there a way to get around this / force the installer to start?

(Note I cannot start the Windows 7 installer either if I wanted to install a second copy of Windows 7 to upgrade to Windows 8)
