I planned to dual boot snow leopard and windows 7 professional both retail.

My rig:so far i checked the component should work with SL unless i made mistake.

P5Q Pro with bios version 2102
Q9550
4gb kingston hyperx 800ghz ram
500gb hd
9600gt asus

My question is how to get this plan going? Should i install snow leopard 1st as i read it will be easier to put windows on osx than osx on windows? i know if i was to install snow leopard i needed to copy all the SL dvd content into a usb drive, so i have my 8gb usb here ready.

also i been readiing all morning, i still dont know how to get this thing going...where to start and what to do 1st. Can anyone please help me?

I am working on the same thing. I had no problem with vista and osx.
trying win7 and osx is causing problems.
