Hi, have not needed to ask much questions over my while at macrumors. Have a quick and pretty simple question that i have not found a reliable enough source to go ahead with the process. I have the 2.26GHZ macbook pro 13". I have lost my recovery CD's. However I'm looking to upgrade to lion OS. Also upgrading the HDD myself. however can i do a OS install using the downloaded Lion OS? (bearing in mind i have not got my recovery CD's) If not, anyone know where i can get hold of a copy of these disks online? Many thanks.
