Windows 7 installation in Paviliom dm1

1. I was trying to install win7 on my laptop, but an error was fired that said the a partition can't be created (no se puede crear una particion). So reading this link I change the boot order to first boot from my unique hard drive and to start the installer at the time the laptop start up I press scape> F9> boot from USB CD/DVD Drive and finally was able to install win7.

I've leave a photo of the installation process on my laptop
