For starters, Windows 7, like past versions does not respect the MBR (master boot record). So you will need to install Windows first, then OSX86. OSX must have a primary partition to boot from also. This can all be done from within, Windows command prompt with diskpart.

Follow this guide: http://www.insanelymac.com/lofiversi...p/t129261.html

The guide is for Vista yes, but it works just the same for Windows 7. Print the guide if you can, or use another computer to read it from.

In addition, if you use Gparted to parition your disks (see the guide) then you will have to delete the partition that you want windows to go in, and recreate it from within the windows 7 installer. It does not like the partitions that Gparted makes and will not install on them. Unless of course you already have Windows 7 installed, then just ignore this last paragraph.

Anyway this is what worked for me. Good luck!
