Hi O recently got my hard drive today and had a windows 7 home premium disk ready to install. However upon instaling i get a message saying " no drives that were signed were found Please make sure that the installation media contains the correct drivers." im stumped because i don't have that said disk to get the drives from. my notebook model is HP 2000-208CA Notebook PC. Oh my Hard drive is a 2.5 inch WD 500 gb black edition.
