MAC OSX running Windows 7

Hi there,

I have an iMac running only windows 7
The purpose of only running windows 7 is to have the aesthetics of a Mac but the functionality of Windows 7. These computers are for K-6 students.
I got Windows 7 to work perfectly but when I restart the machine, the only way for me to run Windows 7 is to hold the Option key. If I don't hold the Option key, the screen will just stay at a white screen.

I do not want Mac on this computer nor do I wnt bootcamp on it, I want it to only run Windows 7, I would really appreciate your help

This link - mac - How do I install a 64-bit Windows 7 on a Macbook Pro without Boot Camp? - Super User - leads me to believe that you NEED to Bootcamp the Mac in order to do what you want...

BUT -- there are supposedly some drivers on the OSX install disk for running Windows on your Mac -- drivers that you install on the Windows side, that is, that might actually facilitate it for you...
