Hi,
I'm going to do a clean installation of Windows 7, because of weird bugs and crashes (could be a virus, but i'm not sure). The problem is - my cd/dvd drive is broken, but luckily I got *.iso copy. Another problem is - i'm using a single hdd.

So, I was wondering is it possible to reformat my hdd (G drive in this case) and do a clean installation of Windows, I'm not sure, because reformating basically means deleting everything that is saved on this disk, including the *.iso file. After installation reformats my disk will it save all the needed installation data somewhere in memory? - because it can't load from nothing, I guess.
