Help!! With Boot Loader / Media Direct Button Change XP / Windows 7

Ok I found this edit using the Dell media direct DVD. It allows you to choose which partition the "Media Direct" button and the "Power" button boots from.

Yesterday I installed OS X on my M1530 and I used that trick and it worked.. When I pressed the Power button I would boot in to Windows XP & When I pressed the media Direct Button I would boot in to OS X. Indeed was nice.

Well OS X Didnt work out for me... So now I would like to do that same Idea
but with Windows 7.

Heres the problem... my setup is obviously 2 partitions on a single drive. Partition 1 is Windows XP and 2 Windows 7. This is how I want it and the reason for me writing this post.
When I install Windows 7 (Vista), its bootloader is used.
When I use the "media direct" button change method here and point the config to partition 2 (Windows7) it doesnt function and errors as there is no loader. However the power button pointed at partition 1 loads the Windows 7 bootloader. So I know that installing windows 7 installs its loader to one partition.
So now my question then I guess is ... How can I install 2 different bootloaders on each partition?

I simply want to load Windows XP from the Power button and Windows 7 from the Media Direct button. It seemed rather simply when I did it with OS X So I hope it is for Windows 7.

I know this is a long post so I thank you all who took the time out to read it.

Later
