How do I install Windows 7 without BootCamp and keep the OS X installation intact? Because I already used BootCamp for creating the partition I used for installing Ubuntu, now I am not able to install Windows 7 by using BootCamp.

Here is my disk partiton configuration:


refit (fat)
osx (hfs+)
freespace (here I want to add the NTFS partition)
linux-swap (raw)
linux-ubuntu (ext4) 


How can I install Windows 7 on the freespace I do have now on the disk? I do not want to destroy osx partition by mistake.
You'll probably need to redo this setup and install Windows 7 before Ubuntu. I am pretty sure if you install Windows 7 it will take over the GRUB bootloader. There is an article on lifehacker that gives instructions on how to set this up http://lifehac.kr/ihVY4k
