I'm going to install windows 7 rc next week on a laptop using the advanced custom install with a full unpartion. Any worries as far as drivers. Will be doing without backup. Connection worries or anything like that?
My only concern is internet drivers (So either Ethernet, or wireless), I would get Vista's latest, and put them on a flash drive incase Windows 7 doesn't automatically install them. Other than that, you should be fine.
