I have an Acer Aspire 6920G. I've been wanting to upgrade to windows 7 but I'm concerned about recovery. My laptop has its own built in recovery so I can revert back to factory defaults. My question is, if I do a clean install, will I still be able to recover back to vista if there's a problem? The recovery has it's own partition, so if I don't touch it, should it be ok? Is it just safer to recover back to defaults and then just upgrade?
