Short and simple, you only need one copy of windows installed.
When you install windows onto your Solid State Drive, it will become your (C:\) drive, and the other hard drive will appear as your (D:\) drive.
Be sure to change the location where your media is stored to point towards the (D:\) drive so you don't fill up the solid state drive with music and movies!
Hi Azathoth, thanks for your help, my second hard drive is F:\ is this a problem because my CD/DVD rom is called C:\ and my system reserved is called E:\. I formatted the soild state drive and put a fresh copy of win 7 on, then i formatted the 500gb hard drive using disk management. When i install game on the big hhd because its totally blank i create a folder in it for the game i am installing, eg call of duty, and i change the location of where the game is going from my C: drive to F:, when i do this i get this message(The folder F: you have selected alteady exists. Installing to an existing directory may overwrite exisiting files and potentially cause some applications to behave abnormally). which it does because when i install COD modern warfare it wont install steam. I hope you can understand what i have wrote and would be gratfull if you can help. Thanks.
