How to install Windows 7 Bootcamp using iso file (without USB/DVD)? I have a MacBook Pro and I need to install Windows 7 besides Mac OS X so I can play games on it.

The problem is that I don't have a USB stick or DVD to copy the Win7 iso image like Bootcamp requires.

Can I install Win7 using an internal partition of my hard disk?
Here might be a solution : 


Create a new partition (at least 8Gig) 
Copy the iso on it
Try booting on it
If it works reboot and create a new Bootcamp partition
Try installing Windows on the bootcamp partition


If this don't work, You'll need a USB drive.
