you need to make your usb flash drive bootable using wintoflash or similar
you cant just copy the iso you need to either extract it or burn it in nero or similar as an image file
where did your iso come from? as this forum has rules against pirated copies
and yes its too big for a cd you need a dvd
My ISO came from the .exe file of which Microsoft gave me. The name of the .exe file is "DLMWin7Pro64US-ISO"
I did manage to download that ISO file to my computer, so I just gotta head out to the store, buy a DVD-RW, and burn it right?
Oh and I know I need to burn it as an image file, I just kinda assumed that the .exe did that for me, guess not
