How to install Windows 7 on a real hard drive

[CrashLaker]

3 important facts:

• 1 - Im using Windows 8 on my Imac by now (note : my Imac is late 2009)
  2 - My cd/dvd drive is broken n external cd/dvd doesn't work
  3 - Uefi only works with Windows 8 (that's why im using it) not with windows 7

You're probably thinking why can't i keep up with windows 8. Well that's because i can't install the graphics driver on it (well that's just another forum case -_-).
And of course no driver -> no games

So i've heard about people that could make that by using virtual box. He said this :

"I installed virtualbox, created a virtual machine with the full disk access (you'll have to unmount all the partitions first and run virtualbox as root), started installing windows, when the copy of the files ended and the vm was rebooting i simply closed it and rebooted my imac and finished the installation directly on the imac, everything went well...
Thanks again for the help".

So could u guys help me figured out how he did that?

I'm on Windows 8 right now.
