I recently got a new asus laptop and some of my programs aren't compatible with windows 8. So i'm trying to downgrade to windows 7 because i never liked w8 in the first place. So when i boot from CD (64-bit windows 7 ultimate) it will install without any problems, but when it gets to the 'starting windows' screen the animation freezes and it just stays there.. I've been looking on various forums and it seems like quite a lot of people are having this problem. A majority of the cases seem to be solved by disabling drivers or updating them. But i'm not sure how to do that from the bios. Help is appreciated!
