I have a hp 15-r131wm Rev: 2213-110 laptop and it came with windows 8.1. Now like an idiot i went and downgraded to windows 7 ultimate 64 bit without making a recovery disk or doing my homework and i dont have the disk it came with. Now i have an os with alot of missing drivers so now i cabt access the internet nor can i download drivers to my usb and put them on because im missing those drivers too! Please help! Next time ill take more precautions.
