Computers Done :D. but my HD is'nt formatted right...

Ok, so when i was installing windows 7 RC, i formatted my HD to....have 64 GB for the OS, 100GB for D and 100GB for E, i think i made a mistake and dident relocate the remainder space....how can i redo it?

Also, how can i make my, lets say, drive E my main drive for all my programs, how can i move Program files from C: to E:? OR are they required to stay in C:. Also, in C:, i have two different program files, "Program Files" and "Program Files 86x", which makes me confused because i have the 64 bit version of windows 7...

Thanks!

OH, btw, where are my ATI drivers relocated to? I dont think firefox lets you put the area where you want your files to be put, my ATI driver disk dident work so i just went straight online to ati and downloaded the windows 7 drivers
