I've been considering Darik's boot & nuke to get rid of s**tty windows installations and get a fresh install. So is anything like bios/ Ethernet etc.'s config stored on hard drives? Also how can I get as near to perfect W7 installation as possible? I've noticed Windows has a general habit of developing exceedingly stupid errors like getting hanged if I use specific page view option, menus not auto closing etc. Any guidance to revert them (many more, hehe)? Daz is not answering : Does the loader insert script on every boot up?
